The Steps on Your Way to Your Individual PERR Log House

After making contact we will inform you about our construction methods. We will explain the possibilities of the various wall structures, soil structures, doors, windows and roof structures. Then we need the building plans or a ground plan, so that we can make an accurate offer. If you do not have a plan yet, we will create a first draft for you on request. After you know about the different possibilities of our construction method, we determine together which positions are to be included in the offer. Of course you can get your desired square log house logs also built as a round log house.

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 building permit 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 will 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 .

Design Description of Our Residential Log Houses

Exterior and Interior Walls

We use woods from domestic, winter-felled pruces, either non-glued or optionally glued, dried, planed and chamfered. The exterior walls are made with wall thicknesses of 20 cm, 22 cm or 24 cm, with triple or fourfold tounge-and-groove connection and corner connection either by so called „Tiroler Schloss“ or corner halving. The interior walls are usually 10 cm, 12 cm or 14 cm thick, with a double or triple tounge-and-groove connection. They are connected to the exterior wall with dovetail joints or a so called „Tiroler Schloss“. The screwing is done with continuous threaded rods. On both sides of door and window openings, vertical T-boards are mounted. Sealing tapes on the corner and longitudinal connections, as well as all holes for threaded rods and electrical lines are included.

Base Connection

The base connection must be made in such a way that the log house is protected from rising moisture and from splashing water. It is also recommendable to cover the base connection with a metal sheet.

Ceiling Above Ground Floor

The framing of beams is made of chamber-dried, planed and chamfered pruce beams, that have been seperated at the core; required joists and abutments are included. The framing of beams is neatly worked into the walls with tenons and dovetail joints.

We manufacture the soil structure from a visible roof boarding made of tongue-and-groove boards – depending on the floor structure – 19 or 28 mm thick. For the remaining soil structure there are a lot of possibilities again. Our offer includes a natural soil structure. This is mainly laid in the bedrooms and the hallway. It consists of a vapour control layer, fibreboards of 10 mm, acoustic panels of 50 mm, a woodfibre insulating board with joint laths 40 mm and tongue-and-groove floor boards 26 mm. The entire soil structure is about 140 – 150 mm high.


As with any other architectural style, there are also many possibilities for the soil structure. Either tiled floor, stone floor, parquet floor… or even floorboards made of solid wood can be laid. Our offer includes all solid wood floorboards, preferably in the bedrooms or in all other rooms where the natural floor is desired.

The head rails and posts are made from dried, planed and chamfered larch woods, the rungs are made from vertical larch boards and can be decorated on request. The balcony can also have a different look according to the design wishes of the client.
