GM Engineering offers competent and approachable structural design for small house builders. Our objective is to work closely with other designers and keep the customer well-informed. We prefer to attend the project at an early stage to integrate the plans with other designers and avoid surprises on site. We operate as the responsible structural designer and depending on the scope and municipality, as the main designer of your site.

We create structural calculations, working drawings and instructions in the following fields:


  • Residential buildings
  • Maintenance buildings
  • Saunas
  • Row houses
  • Maisonettes
  • Wood structures
  • Concrete structures
  • Steel structures
  • Brick structures


  • Extensions
  • Renovations
    • Strengthening of structures, drainage, leaks
  • Alterations
    • New openings to bearing structures
    • Transforming attic to living space
    • Additional floors

Contact us and we can figure out what your project needs to be succesful and lawful.

Hire an expert main designer for your project to handle building permit issues with the municipality. The main designer may be the architect or in many cases the structural designer of the project (depending on the municipality). It is worth hiring an active and professional structural designer and the responsible site manager already at the draft phase so the structural boundaries can be taken in to account when applying for the permit and there is no need to alter the main plans after obtaining the permit.
