Vertical Extension - Student Living

Award Criteria

Architectural Excellence

This project by DMDmodular shows how modular technology can be used even in complex layouts. The building is a three-storey extension on top of a traditional office building from the 1980s in Copenhagen. It adds 77 apartments built from 84 prefabricated modules, covering 2,464 sqm. Despite the non-rectangular shape of the structure, the layout is fully modular, allowing design flexibility with the benefits of standardization. Repeating apartment types and modular units allowed for optimization in production and faster on-site assembly. All apartments are fully finished, with a kitchenette and access to a balcony or terrace. Modules were designed to fit transport dimensions, making logistics efficient. The design includes technical rooms, two staircases, and an elevator, ensuring full functionality and accessibility. This extension blends well with its surroundings while offering a modern and efficient residential solution.

Technical Innovation & Sustainability

This project showcases technical innovation and sustainability through advanced offsite construction. As a modular extension atop an existing traditional building, it required solving major structural challenges. A custom-designed transfer structure was implemented between the old and new parts, ensuring safe load distribution and stability. Fire-rated and thermal partitions with low U-values improve safety and energy efficiency. Double-layer floor and ceiling systems provide enhanced acoustic insulation. Prefabricated balconies were installed with full thermal break, avoiding cold bridging. Offsite production minimized waste, sped up assembly, and reduced the project’s carbon footprint. Sustainable materials and efficient systems were used throughout, lowering energy use and supporting green building goals.

Cost Effectiveness

The project applies cost-effective strategies through the use of modular construction, which minimizes on-site work, shortens construction time, and reduces labor costs. Prefabricated modules are bolted together and can be disassembled or relocated, which adds long-term flexibility and lowers future renovation or expansion costs. Repetition of apartment layouts and standardized production allowed for material optimization and reduced waste. The use of certified, recyclable materials helped lower both environmental and financial impact. Balconies and technical elements were integrated offsite, reducing on-site installation time and errors. Close cooperation with manufacturing partners ensured efficient production and delivery. These methods result in a high-quality, efficient building that meets performance standards while reducing total costs for the user.
