Renovation of your home in Broendby.
Brøndby is a densely built suburban municipality south of Copenhagen with 37,000 residents. The municipality is characterised by a large social housing stock, world-class sports facilities and easy S-train access to Copenhagen. With only 3.5% vacancy and a location close to the Ring 3 light rail line, the housing market is under pressure — and renovation investments can pay off.
