Manufacturing and Assembly

After you have decided for our company, the pre-construction drawing is created. If you have your own architect, the planning can also be done on site. After the approval has been received, the structural calculations such as static and thermal insulation certificate are set up. In consultation with the heating engineer and the electrician, the construction documentations are prepared and transferred to the participating companies and the client for review.

Once the plans have been approved, the PERR Log House is milled and cut on computer-controlled special machines with millimeter precision. We drill all holes for power and installation lines exactly according to the plan.

Due to the high level of prefabrication of the PERR Log Houses, hardly any machining is necessary during assembly. This ensures fast construction progress.

Foreman Assembly

Also the large log houses by PERR are delivered compactly in a construction-kit. In case of a larger log house, we recommend you, to demand our carpenters assistance – at least until the roof truss is standing. Getting assisted by 3-4 workers, who are comfortable with working on a rooftop, you’ll move on with the project soon.

Weatherproof Assembly / Final assembly

Your house is professionally assembled by our experienced carpenters. You can also choose between different construction possibilities, for example either the complete final assembly or only the assembly of the builiding envelope (with or without tile roofing) or the assembly without windows or without floors etc. We build your log house to the extent you request .
