New housing and commerce linked by a green outdoor space
In a central corner in Copenhagen, 15.000 m² housing and offices are being built to exploit some tricky geometry, to create harmony between the existing and new buildings, and to make space for green common areas.

The integrated residential and commercial complex, covering a total of 15,000 square meters, is conceived as a cohesive whole—comprising a new office building, an infill block of apartments, and the partial transformation of a heritage industrial property into housing.
The residential building reuses elements of the existing structure along Jagtvej and varies in height from five to seven storeys where it meets the original building.
The project also includes an underground parking facility, landscaped courtyards, and ground-floor functions designed to activate urban life.
Multifunctional building for a central location
The two different-purpose buildings are situated in a busy and architecturally complex area of the city, meaning that the best solution and the best utilisation of the geometry is to separate the two types of building, and yet render them a certain cohesion through a common green outdoor area.
The nine-storey office block, named 21Ø, gradually drops down to four storeys towards Aldersrogade to fit in with the surroundings. It appears as an independent building towards Vibenshus Runddel, while the homes are more secluded and appear as a continuation of the existing residential block.
The building is carefully shaped in response to the site conditions – it is precisely adapted to the triangular plot and steps down towards Aldersrogade to four storeys, ensuring that the neighbouring buildings retain their views.
Dialogue with Context
The commercial volume asserts itself as a distinct, solitary element towards Vibenshus Runddel, while the residential component is set back, integrating seamlessly as a continuation of the existing urban block. The development comprises 77 rental apartments, intended for both students and families, alongside approximately 600 workplaces. At ground level, provision is made for retail functions.
The transition between programmes is articulated through a landscaped communal courtyard – a green breathing space within an otherwise dense and noise-exposed urban setting.
Vertical window bands draw daylight deep into the building and contribute to a façade expression that evolves with the rhythm of the day and the seasons. The architectural surfaces are never static; each plane engages dynamically with light and its urban surroundings.
According to the plan, the building must be awarded the DGNB gold certificate.
The colours and materials in all the facades are in line with the surrounding buildings, and a noise barrier, common terraces on roofs, good reception areas, etc. have also been integrated in the plans to create attractive surroundings to work and live in the heart of Copenhagen. Green roof terrace and courtyard gardens
We have established green areas for residents above an underground carpark between the housing and offices. Footpaths wind between trees and areas for cycle parking. Via terraces and steps, there is access to a courtyard garden from the ground-floor flats.
