Discover What takes shape here
Timber buildings for
garden, home and everyday life.
It starts with a place and an idea. Holzmeisterei Frenken develops a building that fits its use, surroundings and budget – and guides it through to installation.
Personally guided
One contact
from design to installation.
From the first sketch to installation, responsibility stays in one pair of hands. This keeps the idea, construction and details on site working together.
If structural engineering, approval or other trades are required, responsibilities are clarified early. That creates certainty before the actual work begins.
- Direct
- One consistent contact for the entire project.
- Continuous
- Planning, making and installation work together.
- Master craftsmanship
- Well-resolved details, including those that are barely visible later.

Built for everyday life.
