Renovation works

Renovation is a different craft from new construction: the walls are already standing, and every one of them holds surprises. Old buildings demand experience — knowing what can be opened up and what must be propped, what carries load and what only appears to.

This is where the engineering background is worth the most: we create wall openings and modify load-bearing structures safely, coordinated with a structural engineer. From demolition to paint-ready, the project stays in one hand.

Frequently asked questions

Can you work in an occupied home?

Yes, with phased room-by-room work and dust protection. We leave the place tidy at the end of every day — our clients say it is our trademark.

Do I need a permit for interior remodelling?

Usually not for non-load-bearing partitions; modifying load-bearing structures requires a structural design. At the survey we tell you what is needed — and help with the engineering coordination.

How long does a complete flat renovation take?

A complete renovation of a 50–70 m² flat typically takes 6–10 weeks from demolition to paint-ready, depending on scope. We give a written schedule and keep to it.

Do you handle debris removal too?

Yes, containerised removal and certified disposal of demolition debris is part of our service.
