Densification & Rooftop Extensions

  • Homepage
  • > Timber Construction
  • > Densification & Rooftop Extensions

We make use of existing commercial and retail areas such as supermarkets, retail parks and parking lots to create new living space. This sustainable approach expands the potential uses of existing sites and helps ease pressure on the housing market. At the same time, modern residential concepts are created that blend seamlessly into the existing environment and contribute to the long-term positive development of the location.

Your Benefits

  • Land Efficiency & Site Optimisation
    Maximising land utilisation through additional usable space — without the cost of acquiring new land
     
  • Site Enhancement
    Added value through additional functions and space — increasing the attractiveness and financial performance of the location

Our Approach: Design-Build

We accompany you from the first idea to the completion of your building. Within just two weeks, you receive:

  • A project study
  • A rough cost estimate
  • An initial life-cycle assessment
