The outlook and often also the structural solutions of our log homes are individual, based on our customer’s wishes, but are also subject to local and national requirements and regulations.


Log house - External walls

Painumaton hirsinurkka, 200x220 mm


Non-settling massive wooden wall construction, that is well suited for modern and diverse architecture. Creates new, ecological solutions also for public building.

Square log wall

Square log wall is suitable for many kinds of buildings. In a house that is designed for a permanent home the log wall must be at least 270 mm in thickness. That way no extra insulation is needed but compliance with energy regulations must be taken into account in the design.

Höylähirsiseinä, lyhytnurkka


Square log wall withouth traditional cross corners fits well in urban environments and modern log houses.

Sisäpuolelta eristetty hirsiseinä

Log wall with internal insulation

This is suited for holiday homes that are heated only occasionally during winter. If this structure is to be used in a building intended for winter living, special attention must be paid to the ventilation between the insulator and the logs as well as sufficient insulator thickness.


Round log wall

The round log wall can be used in a similar manner to the square log. Both can be executed with laminate structures and they are suitable for all kinds of building types as they are or with extra insulation. The diameter of the round log must be approximately 300 mm if it is to be used without extra insulation. An extra-tight corner solution with a special structure is available for larger round logs.

Passiivihirsitalon seinä

Passive log house walls

Our wall structure meets the upcoming requirements for zero-energy buildings. The compact and durable wall structure is healthy and has excellent thermal insulation properties. The inner side of the external walls is lined with vertical logs, followed by steam-proof fibre fabric, a thermal insulation layer, a wind-proof layer, air gap and cladding.

Roof and intermediate floor structures

Roof structures

The insulator thickness required by the total energy calculation must be taken into consideration. Extra insulation can be fitted below or above load-bearing roofing abutments. The structure and seals of the roof must always be checked on a case-by-case basis to ensure faultless function and good insulation.

Intermediate floor structures

Our log frame manufacturing and wood joint methods enable clean and beautiful visible structures for floor joist frames, roofs, terraces and balconies.

Connecting intermediate floors to external walls in passive log houses

As an altenative to the traditional structure, the intermediate floor of a passive log house can consist of approximately 10 cm thick solid wood panel with timber joists and the floor surface material on top of it Making the external wall airtight is easy, as the adjacent illustration shows. This wall design allows for continuous air barrier installation on the outer side of the log wall, as it eliminates troublesome joints. This results in a structurally sound house with improved indoor air quality, airtightness and moisture resistance.
