District center and city park

With the complex urban redevelopment project De Harmonie, Antwerp has had a new public space since fall 2021. In the southern part of the city, Rotterdam-based studio Kempe Thill and local firm RE-ST architecten transformed the former ballroom and concert hall of the Société Royale d’Harmonie into a new district center, which now houses offices for the municipal administration, a large civic center and an event space for concerts, among other things. The architects combined the concert hall, which has been a listed building since 1997, with an existing town house and the former orangery and extended the building to include a meeting center. They also redesigned the historic park and had the fountain designed by Henry van der Velde restored. The project was originally an open architectural competition organized by the Flemish government (2010) to transform the concert hall into a “Silent Room”. In 2013, however, it was decided to develop the building as a district center.

A look at the history of De Harmonie in Antwerp

De Harmonie is the former summer concert hall of the Société Royale d’Harmonie music society, founded in 1814. The then 25-year-old Pieter Dens, who later became the city architect of Antwerp, won the architectural competition for it. In 1846, after just two years of planning and construction, the ballroom and its private landscaped garden were opened. The neoclassical building was characterized above all by the flowing relationship between the interior and exterior spaces and served as a festive setting for the open-air concerts. A conversion in 1890 doubled the volume of the building.

At the beginning of the 20th century, however, the Societé’s concert business began to decline, which was exacerbated by the outbreak of the First World War. The city therefore took over the building and the garden in 1922. The landscaped garden was then converted into a public park and the concert hall was used as an exhibition hall. In the late 1970s, the building was converted into a nightclub. Acoustic suspended ceilings were installed in the partly preserved historic interior spaces and the opening to the garden was closed. The 2010 tender was intended to help fundamentally re-roof and reinterpret the 170-year-old De Harmonie ensemble. In addition to restoring the concert hall, which was in dire need of renovation, the city of Antwerp also wanted a new connection for the various buildings on the site.

The building

In order to connect the various buildings, Atelier Kempe Thiel devised a sensible overall organization for the new complex. On the north side of the concert hall, they built an access structure that connects all the functional areas with each other and provides barrier-free access. They also lined up the different functional areas along the new west-east axis. The architects organized all the necessary ancillary rooms such as the café, offices and meeting rooms along this corridor in order to free the historic rooms from new functional constraints. The connecting structure is only partially visible between the orangery and the concert hall as a new covered entrance hall – and on the east side of the complex as a conference pavilion. Towards the historic Stadthaus, the connecting building forms a small, green inner courtyard.

Renovation of the façade

The aim was to restore the classical character of the concert hall as far as possible. For this reason, after extensive research and consultation with the monument preservation authorities, a glass pergola in front of the main façade from 1890 was demolished to expose the original volume of the building. The balustrades that once existed in the attic area were added in a modern, abstract form. The architects interpreted the windows of the façade in a neoclassical style with four-metre-high double-glazed doors. They also reconstructed lost ornamentation. Atelier Kempe Thill based the color scheme on a neoclassical color spectrum. Light gray plaster and medium gray windows were combined with the existing dark gray limestone base made of Belgian granite.

The redesign of the interior of the De Harmonie concert hall

The architects also developed the original neoclassical design further when designing the interior. They removed the suspended ceilings and exposed the remaining stucco fragments. However, as there was little information about the historical interior, it was not reconstructed. The architects worked with gray terrazzo in the form of wall and column cladding. They had the existing wooden columns clad with handmade terrazzo elements. The abstract capitals look both traditional and contemporary at the same time. All technical elements, such as the ventilation system, smoke extraction, hall lighting and theater technology, were carefully integrated into the historical ensemble.

An English landscape park for the 21st century

Together with LAND landschapsarchitecten and ARA (both Antwerp), Kempe Thill redesigned the existing park along the lines of an English landscape garden. A number of large trees were felled and shrubs and fences removed to create more open play and exercise areas. At the same time, the edges of the park were planted more densely to create more intimacy and security and to visually block out the surrounding roads, some of which are very busy. In their design, Kempe Thill completely removed the existing network of paths in order to create as much unsealed space as possible. Towards the former concert hall, the site was slightly lowered to better integrate it into the park. A key element of the design was to open up the building towards the park in order to restore the flowing, characteristic relationship between inside and outside. The restored orangery was converted into a café. The newly designed tranquil city park now forms an intensively used green oasis in Antwerp and invites visitors to enjoy a wide range of activities.

The Olympic Park in Munich also impresses with its design and versatility. Read everything you need to know about its 50th anniversary this year here.

Anyone who enters a large landscape garden experiences nature as a work of art: vast lawns that gently give way to groups of trees, winding paths that continually draw the eye in new directions, bodies of water that reflect the sky, and sightlines that stretch across hills and valleys. The large landscape garden is one of the most influential inventions in European garden design—a design philosophy that, since the 18th century, has fundamentally redefined the relationship between people, nature, and space, and continues to shape open-space planning to this day.

Definition and Classification: What Is a Large Landscape Garden?

The large landscape garden, known in English-speaking countries as a “landscape garden” or “English landscape garden,” is a type of open space that deliberately eschews the formal, geometric garden design of the Baroque and Renaissance periods and instead takes an idealized natural landscape as its design basis. It is characterized by meandering paths and shorelines, freely shaped bodies of water, irregularly arranged groups of trees and shrubs, expansive lawns, and a carefully staged sequence of spatial impressions. The word “large” refers not only to the area—which in fact often spans several hundred to over a thousand hectares—but also to the conceptual aspiration: the garden as a reflection of a complete, internally coherent landscape.

The large landscape garden differs fundamentally from the Baroque palace garden in its design logic. While the Baroque garden controls and organizes nature through symmetry, axes, parterres, and topiary (the pruning of trees and shrubs into geometric shapes), the landscape garden simulates the random, the organic, and the picturesque. This simulation, however, is by no means random: It is based on precise design decisions and the deliberate use of topography, vegetation, water, and architecture to create specific moods, visual relationships, and spatial experiences. In this sense, the landscape garden is a highly refined art form that conceals its methods.

Typologically, the large landscape garden can be distinguished from smaller landscape-style home gardens, 19th-century public parks, and modern city parks, even though all these types have emerged from it or been influenced by it. The decisive difference lies in scale and intention: the large landscape garden is a total work of art that reinvents an entire landscape, whereas the 19th-century city park primarily served social and hygienic purposes, and the landscape-style private garden merely borrows formal elements.

Historical Origins: England, the Enlightenment, and Criticism of the Baroque

The roots of the grand landscape garden lie in early 18th-century England, where a combination of philosophical, literary, and political currents gave rise to a new aesthetic of nature. The Enlightenment, with its trust in reason and the observation of nature, stood in productive tension with the contemporary longing for the sublime and the picturesque—that is, for landscapes that evoke awe, vastness, and irregularity. Poets such as Alexander Pope, philosophers such as Anthony Ashley Cooper, the third Earl of Shaftesbury, and painters such as Claude Lorrain and Nicolas Poussin—whose landscape paintings served as direct models—shaped the aesthetic program of the new garden style.

The gardens at Stowe (Buckinghamshire), Stourhead (Wiltshire), and Rousham (Oxfordshire) are considered key early examples. At Stowe, Charles Bridgeman, William Kent, and finally Lancelot “Capability” Brown—who would become the most influential landscape architect of the 18th century—worked in succession. Brown earned his nickname “Capability” from his habit of identifying the “capabilities” of a site for improvement. His style, characterized by meandering lakes, gently undulating lawns, clusters of trees, and belts of trees along the edges, became the epitome of the English landscape garden and influenced hundreds of gardens throughout Great Britain.

At the same time, a theoretical debate developed about the picturesque, led primarily by William Gilpin, Uvedale Price, and Richard Payne Knight. These authors criticized Brown’s style as too smooth and too orderly and called for a rougher, wilder garden aesthetic more closely aligned with painting. This debate is important for understanding the grand landscape garden because it shows that the style was not a uniform doctrine but a dynamic field of aesthetic debate.

The landscape garden style reached Germany in the second half of the 18th century, initially through travelogues and publications, then through direct commissions of English gardeners and the work of local designers such as Friedrich Ludwig von Sckell, who laid out the English Garden in Munich, and Peter Joseph Lenné, who had a decisive influence on the Potsdam park landscape surrounding the New Garden and Sanssouci Park. Prince Franz von Anhalt-Dessau created the Wörlitz Park, the first significant landscape garden project on German soil, which is now a UNESCO World Heritage Site. In these German gardens, the English landscape style is often combined with Enlightenment-era educational programs: temples, inscriptions, monuments, and symbolic structures transform the garden into a walk-through total work of art with a moral and political message.

Design Principles and Design Elements of the Grand Landscape Garden

The grand landscape garden employs a range of design elements that, when combined, create its characteristic spatial experience. The most important element is the staging of visual relationships: the path through the garden is a sequence of images that the designer has deliberately composed. Axial views open up onto temples, bridges, or bodies of water; groups of trees and shrubs frame vistas and block unwanted views; hills and depressions create moments of surprise when, after an ascent, a sweeping view suddenly opens up.

Water plays a central role. Natural or artificially created lakes and ponds with irregular, curved shores are a hallmark of the style. Capability Brown was famous for transforming rivers into expansive lakes through damming, which gave the impression of natural bodies of water. The reflection of the sky and the surrounding vegetation on the water’s surface significantly enhances the sense of depth in the space. Bridges, islands, and shoreline plantings complement the body of water as design elements.

Vegetation is conceived not as individual plants but as mass and volume. Solitary trees—that is, freestanding individual trees with distinctive shapes or sizes—provide focal points within the lawn. Groups of trees and shrubs of varying sizes and compositions structure the space and create a layering of foreground, middle ground, and background reminiscent of landscape painting. Belts of trees and shrubs along the garden’s edges enclose the grounds from the outside and create the impression of a self-contained world. The lawn itself, referred to in the original English as “lawn,” is not merely leftover space but a design element: it connects the groups of trees and shrubs, guides the eye, and gives the garden its sense of expansiveness.

Architectural features—such as temples, grottoes, ruins, bridges, obelisks, and similar structures—complete the picture. They are not functional buildings but rather convey meaning: they allude to ancient models, literary themes, or the client’s worldview. Ruins, whether genuine or artificially created, are a particularly characteristic element because they symbolize transience and the superiority of nature over human creation—a central theme of Enlightenment aesthetics.

Plant Selection and Vegetation Design in the Landscape Garden

The use of plants in large landscape gardens follows different principles than in formal gardens. The focus is not on the individual plant with its botanical characteristics, but on the effect of the mass of plants within the space. For woody plantings, native tree species were and continue to be used predominantly; in Central Europe, these include oak, beech, hornbeam, linden, ash, maple, and alder, supplemented by introduced species such as plane tree, horse chestnut, and various conifers, which have been widespread in European landscape gardens since the 18th century.

Creating woody plantings in the landscape garden style requires thinking in terms of long time frames. A tree planted today as a solitary specimen will not fully unfold its spatial impact until decades later. Capability Brown is said to have remarked that he worked for posterity, not for the present. This temporal dimension is a fundamental difference from architecture: the landscape garden is never finished; it changes continuously through the growth, aging, and loss of trees and shrubs. Professional care and maintenance must guide this process without destroying the original design concept.

The lawns of historic landscape gardens were originally maintained through grazing by sheep and cattle, which also served an ecologically valuable purpose. With the invention of the lawn mower in the 19th century and the increasing mechanization of maintenance, maintenance practices changed fundamentally. Today, those responsible for maintenance face the challenge of balancing the preservation of the historic character, the demands of visitor use, and the goals of promoting biodiversity. Extensive meadow management with infrequent mowing, the creation of wildflower strips, and the promotion of old-growth wood in groups of trees and shrubs are strategies that are increasingly being incorporated into modern maintenance concepts for historic landscape gardens.

The introduction of exotic woody plants, particularly rhododendron species and conifers from North America and East Asia, was a significant expansion of the plant repertoire in the 19th century. Many historic landscape gardens today contain significant collections of these species, which have since acquired historical value in their own right. At the same time, Rhododendron ponticum has become an invasive problem in Atlantic-influenced regions of Great Britain and Ireland, threatening the ecological integrity of historic sites. This tension between historical authenticity and ecological responsibility is a central theme in today’s preservation of landscape gardens.

Maintenance, Preservation, and Management Concepts for Historic Sites

Historic landscape gardens pose special challenges for heritage conservation because their heritage value lies not in solid materials but in a living, ever-changing composition of vegetation, topography, water, and architecture. The challenge lies in preserving the spirit of the original design without freezing the growth of the vegetation or reducing the site to an artificial state. Maintenance concepts for historic landscape gardens must therefore be based on a careful historical analysis that evaluates sources such as original plans, paintings, engravings, travelogues, and plant lists.

In Germany, historic garden conservation has established itself as a distinct discipline situated at the intersection of landscape architecture, historic preservation, and garden history. The Florence Charter, a document adopted in 1981 by the International Council on Monuments and Sites (ICOMOS), defines principles for the preservation of historic gardens and parks. It emphasizes that the historic garden is a living monument that requires continuous care, and that restoration measures must be based on documented sources.

Practical maintenance tasks in historic landscape gardens include the regular inspection and care of tree and shrub populations, the preservation and restoration of water features and ornamental structures, the maintenance of lawns and paths, and the management of visitor flows. The latter is a particularly complex task in heavily visited sites such as the English Garden in Munich or Sanssouci Park in Potsdam, where user needs, historic preservation, and ecological goals must be balanced. Foot traffic, soil compaction, and damage to the root systems of old trees caused by visitors are real threats that are mitigated through route guidance, signage, and, if necessary, temporary closures.

Significance for Contemporary Open-Space Planning, Climate Adaptation, and Biodiversity

The large landscape garden is not a museum relic, but rather a reference model that remains highly relevant for today’s open-space planning and urban development. Its fundamental principles—the linking of open spaces into contiguous green spaces, the use of topography and water as design elements, and the creation of spatial diversity through the alternation of open and enclosed areas—are reflected in modern concepts such as the Green Belt, Green Infrastructure, and the 21st-century city park.

In the context of climate adaptation, this type of landscape garden offers specific advantages. Extensive stands of trees and shrubs create cooling effects through evaporation and shading, which are increasingly in demand in overheated cities. Extensive lawns and water bodies help regulate the urban water cycle by absorbing, temporarily storing, and gradually releasing rainwater. The topography of many historic landscape gardens—with hollows, depressions, and ponds—corresponds in its basic structure to the principle of the “sponge city” (a concept of water-sensitive urban planning), which is currently being discussed as a response to increasing heavy rainfall events.

For biodiversity, large-scale landscape gardens—with their stands of mature trees, extensive lawns, bodies of water, and wooded edges—serve as valuable habitats. Old oaks, beeches, and linden trees, with their hollows, cracks, and dead branches, provide habitat structures for bats, woodpeckers, beetles, and numerous other species that can hardly find a place in intensively used urban landscapes. Promoting deadwood, adopting a more extensive approach to lawn care, and creating riparian buffer zones are measures that can enhance the ecological value of historic landscape gardens without compromising their character.

At the same time, open-space planning must critically reflect on what the grand landscape garden historically also was: an instrument of land acquisition and social segregation. Many of the most significant English landscape gardens were created through the enclosure and transformation of common land—a process that displaced villages and dispossessed farmers. This socio-historical dimension is essential to a complete understanding of the type, even if it does not negate its aesthetic and ecological value.

The Grand Landscape Garden as an Enduring Design Model

The large landscape garden established a design philosophy that extends far beyond its historical context of origin. The idea that open space is designed not through geometry but through reflection on spatial sequences, visual relationships, movement, and atmosphere remains a fundamental principle of landscape architecture to this day. Anyone planning a city park, a park complex, or a large-scale open space works—consciously or unconsciously—with techniques developed in 18th-century English landscape gardens.

The strength of this typology lies in its adaptability. The large landscape garden can serve simultaneously as a recreational space, a nature conservation area, a climate buffer, a cultural heritage site, and a source of urban identity. It requires its planners and caretakers to think in the long term, to understand ecological processes, and to exercise aesthetic judgment that transcends short-term trends. This combination makes it a challenging yet rewarding field of practice for landscape architecture.

The great historic gardens—from Stourhead to Wörlitz to the English Garden in Munich—are not only testaments to a bygone era of garden art, but also living laboratories where one can observe how vegetation, topography, water, and architecture have interacted over the centuries. Anyone who walks through these gardens with a knowledgeable eye learns more about open-space planning than from many textbooks. The grand landscape garden remains what it has been since its inception: a design model of extraordinary depth and durability.

How do our metropolitan areas need to grow and what do cities still need to learn in the future? Look forward to the mini-series “Cities for tomorrow 2021”.

Three issues, three questions and definitely three topics that no city, no municipality, no planning department, no planning division can ignore. In the three-part series “Cities for tomorrow 2021”, we ask: How do our metropolitan areas need to grow in the future? What can rural areas learn from cities and vice versa? And: How can we as planners promote diversity and tolerance in urban areas? Join us to experience and analyze new approaches to urban development, different constellations of players and impressive best practices.

(Issue 04/21)

The total population in Germany will change only slightly by 2035. Nevertheless, the demographic trend will hit us with full force – both in the metropolitan areas and in rural areas. In the April 2021 issue of G+L, our focus is on metropolitan areas and their increasing growing pains. We take a look at Frankfurt, Hamburg, Leipzig, Paris and Potsdam and critically discuss how cities will deal with the increasing pressure on space in the future without cannibalizing their green spaces.

Planning between city and region

(Issue 05/21)

Around 60 percent of German districts and independent cities will lose population by 2035. Eastern Germany in particular is massively affected by shrinkage, but the “old federal states” are also struggling with population losses. At the same time, numerous regions are having to absorb and compensate for the growth of nearby metropolitan areas. In the May 2021 issue, we turn our attention to rural areas and ask how urban and rural areas can support and learn from each other in terms of healthy development.

The diverse city

(Issue 06/21)

Since 2019, around 100 Polish local governments have declared their regions to be “LGBT-free zones”, while the small Hungarian town of Nagykáta followed suit in November 2020 and also passed a resolution banning the “dissemination and promotion of LGBTQ propaganda”. According to the Gay Travel Index, homosexuals face the death penalty in 15 countries worldwide. In the June 2021 issue, we want to set an example against LGBTQ phobia with positive examples. We present the Queer Inclusive Planning approach and discuss with experts from urban planning and society how we can support and promote diversity and tolerance in our cities through planning.
