Measure first
Every renovation starts with on-site measurements of energy use, moisture, and structure.
Structural & energy engineering
Buildings that last longer and use less.
We design timber structures and energy renovations for housing, schools, and offices — from the first sketch to the last site visit.

How we work
Small teams, one engineer responsible from start to finish, and decisions based on measured data.
Design with timber
Cross-laminated timber and glulam replace concrete and steel wherever it makes sense.
Follow it through
We stay on the project during construction and check the results a year after handover.
