Villa Extension
The design of the extension to the villa was a challenging process since the new program is twice as big as the main historic villa. To make a functional extension and at the same time respect the historic villa, we propose an equal relationship between the villa and the new garden house. From the historic lakeside, we maintain the historic view with the iconic villa in the foreground overlooking the prominent landscape. From the entrance side, the garden house is put forward marking a clear entrance and main entrance for the different users.

Human Scale
Living in the observation home the kids and families are met with a soft and human scale in harmony with the natural setting. The building is constructed and cladded in wood and the material gives a natural and warm atmosphere in and around the building.

Living Spaces
Between the individual apartments, the garden house is programmed with common living rooms. From the living rooms there are accesses to the garden or generous balconies overlooking the garden and lake.

Voluntary sustainability standard
Serving as a test project for Den Frivillige Bæredygtighedsklasse (Voluntary sustainability standard) the Bagsværd Observation Home project seeks to embrace both environmental, climate, social, and economic quality. The standard can be seen as a preview – and a test – of how future climate-oriented regulations of construction can be incorporated into future building regulations.
Having a major impact on the CO2 footprint, we have, among other things, focused on the materials we use in the building. The use of wood, including all the CLT elements, helps us to get below 8 kg. CO2 equivalent per m2 per year, which are the requirements for the standard.
