Project ยท renovation and extension
A 1920 semi-detached house in a protected townscape: stripped back, extended over two storeys and made all-electric.
The project
The house dates from 1920 and stands in a protected townscape in Bussum. When we started it had energy label F, a gas boiler from 2004 and a geyser for hot water, and only the walls were insulated.
We ran the project from the first drawings through to planting the garden: the architectural and structural drawings, the permit application, a two-storey extension, a new roof and an installation that runs on electricity alone.
149 mยฒ of living space before the works, on a plot of 244 mยฒ.
