Urban timber construction in Berlin – a remarkable project is currently establishing itself in the heart of the capital: “Haus 2+”, a new three-storey building in eye-catching red that serves as the latest access point to the Holzmarkt 25 cultural quarter. It is an architectural statement – uncompromisingly sustainable, precisely planned and embedded in a creative microcosm directly on the banks of the Spree.
The location itself is already a chapter in Berlin’s urban culture: Holzmarkt was once a central transshipment point for timber, later a GDR border area, then a wasteland. In the early 2000s, it became a stage for alternative urban culture – with the legendary Bar25 paving the way for today’s Holzmarkt 25 cultural area. Today, the quarter is home to concert halls, studios, workshops and restaurants – and the new Haus 2+ is a striking architectural and functional highlight.
House 2+, designed as an extension to the existing building complex along Holzmarktstrasse, provides a strong counterpoint to the urban surroundings with its confident red wooden façade. With a gross floor area of around 200 square meters and three levels, it combines an unusual mix of uses: a local bakery, a booking agency, a tattoo studio and a physiotherapy practice.
This mix is no coincidence – it reflects the open, permeable self-image of the district. Here, crafts, creative industries and healthcare merge into a living microcosm of urban diversity. The fact that this microcosm is built in wood not only lends the ensemble a warm atmosphere, but also sends a strong signal for resource-conserving construction in an inner-city context.
According to the responsible planners, House 2+ is the first almost 100% timber construction on the site. It is based on LIGNATUR ceiling elements that meet static, thermal and acoustic requirements in equal measure. The element ceilings take up the projections and recesses of the geometry via cantilevers – and at the same time allow a visible soffit that emphasizes the material honesty of the building.
Inside, the cavities are filled with chippings to optimize sound insulation – particularly relevant in view of the small-scale use. The integrated thermal insulation allows a cantilever without thermal bridges, which combines energy efficiency and structural clarity. The timber elements weigh just 50 kilograms per square meter, which enabled a particularly fast and minimally invasive construction method – an advantage that should not be underestimated in the middle of a busy, densely used district.
Despite its lightness of design, the building meets the high fire protection requirements for multi-storey timber construction. Certified fire barriers within the ceiling modules ensure reliable safety without compromising the architectural expression. The solution: a consistent, prefabricated construction method in which all safety-relevant aspects were already integrated into the design at the planning stage.
In functional terms, Haus 2+ is far more than just an extension of the existing infrastructure. As a new access point to the Holzmarkt quarter, it acts as an architectural threshold between public space and creative biotope. Its striking form, composed of clear geometric bodies, emphasizes the transition from urban street space to an informally organized, mixed-use world.
At the same time, the building does not appear forbidding or closed off – on the contrary. The colorfulness, the openness of the first floor use and the diversity of the tenants make Haus 2+ a lively part of the banks of the Spree, inviting passers-by and visitors alike.
On an urban planning scale, Haus 2+ shows how modern timber construction can succeed in dense urban spaces – functionally, aesthetically and sustainably at the same time. Its high level of prefabrication, visible materiality and flexible usability make it an exemplary project for the future development of Berlin, particularly in light of the growing demands for climate protection and resource-saving construction.
At the same time, the building is not an isolated lighthouse project, but part of an urban experiment that has focused on mix, participation and sustainability from the outset. The Holzmarkt 25 district remains a model of what urban transformation with social aspirations can look like – and Haus 2+ now provides architectural proof that climate-friendly construction is not only possible, but can also be outstanding in terms of design.
House 2+ is red – and sends out a signal. It stands for a new generation of urban architecture: resource-conserving, flexible, inviting. As an architectural building block in the creative fabric of the timber market, it impressively demonstrates how urban timber construction can be realized in Berlin – not as a marginal phenomenon, but as a sustainable model for urban construction in the 21st century.
