What goes into every MF Timber House cabin
No mystery materials and no proprietary names that mean nothing. This is what arrives on the lorry and what it is made of, with the figures taken straight from our model catalogue.
Structure: solid Nordic pine and spruce
The walls are solid, precision-milled Nordic logs, not a frame with cladding pretending to be logs. Depending on the model they are 44 mm or 70 mm thick, with machined interlocking profiles so each course seats into the one below without gaps that need filling later.
Nordic pine and spruce are slow-grown, which gives tight growth rings, high resin content and better dimensional stability than fast-grown timber. That stability is what keeps doors and windows operating correctly after the building has been through a couple of Irish winters.
Structural specification across the range
| Wall logs | 44–70 mm solid Nordic pine or spruce, machined interlocking profile |
|---|---|
| Floor insulation | 100–150 mm, included as standard |
| Roof insulation | 100–200 mm mineral wool in a three-layer thermal, acoustic and moisture build-up |
| Roof covering | Galvanised steel, tile-look profile, anthracite |
| Windows and doors | Double-glazed timber joinery, with shutters and solid wood doors |
| Optional upgrade | Double wall insulation kit — extruded polystyrene in walls and floor |
| Foundations | Concrete foundation blocks supplied and set as part of the assembly |
Roof: three layers, then steel
The roof does most of the work in this climate, so it gets the most attention. Above the structure sits a three-layer build-up that handles heat, sound and moisture together — a mineral wool blanket of 100–200 mm depending on model, with the vapour and moisture layers that keep it dry and working.
The covering is galvanised steel in a tile-look profile, finished in anthracite. Steel was chosen over felt shingles for the Irish market for a straightforward reason: it sheds wind-driven rain, it does not lift in a storm the way shingle edges can, and it has a far longer service life with no maintenance.
Worth knowing: The roof is anthracite on every model, and that is deliberate. It is the only colour that holds up reliably in this climate without going chalky, so we do not offer alternatives rather than offer one we would not stand behind.
Joinery: timber, double-glazed, with shutters
Windows and doors are double-glazed timber units with shutters, and the external doors are solid wood. Timber joinery was an easy decision in a timber building: it moves with the structure in the same way and at the same rate, which is where PVC units in a log wall tend to cause trouble.
Glazing is where comfort is won or lost in a small building, because the window area is proportionally large. If the cabin is going to be a winter workspace rather than a summer room, this is the part of the specification worth discussing before you order.
What is not in the price
Being specific about exclusions saves everyone a difficult conversation later. The shell version includes the structure, the roof, the joinery, the standard insulation, the foundation blocks, delivery and assembly. The turnkey version adds hot, cold and drainage pre-installation for the bathroom, and a shower, toilet and sink kit fitted.
Electrical work is not included in either version and we do not quote a figure for it. It is priced and carried out separately by the electrical contractor we work with, because the installation has to be certified by a registered electrician and the scope depends entirely on your site and existing supply.
- Site levelling beyond setting the supplied foundation blocks is quoted separately.
- Connection to water and drainage beyond the pre-installation in the turnkey version is a local plumbing job.
- Electrical installation and certification: quoted by our partner electrical contractor after a site review.
- Decking, terraces and verandas are available on some models and priced per project.
Frequently asked
What thickness are the log walls?
Between 44 mm and 70 mm of solid Nordic timber depending on the model, with machined interlocking profiles. The thicker 70 mm walls appear on the larger models in the range. The specification for each model is listed on its own page.
Can I choose a different roof colour?
No, and that is a deliberate decision rather than a limitation of supply. The roof is galvanised steel in anthracite across the whole range, because in the Irish climate it is the finish that holds its appearance over time. The same applies to the cabin as a whole.
Is the timber treated before delivery?
The timber is factory-prepared, and exterior surfaces need a protective finish as part of the build and recoating on a cycle afterwards. How often depends on exposure — an Atlantic coastal site needs attention sooner than a sheltered inland garden. Our maintenance guide sets out the schedule.
