Solid wood

[bunni]

Hello!

First, I just have to say that both I and my partner have absolutely NO knowledge or experience in house building. So what I'm asking about may sound really silly, but I hope that those of you reading this understand

The thing is, we have bought a plot in Oslo and have already involved an architect for floor plans and bounced some ideas back and forth.
It's decided that we will build in about 2.5-3 years, so I want to believe that we have plenty of time to think about what we want.

I (and my partner) have become interested in building a solid wood house. Simply because we can't see any disadvantages with it, and the area where the plot is located is partially in the forest, but close enough to Oslo that we feel the theme of solid wood fits perfectly.

I have Googled a lot about solid wood. We are still looking for suppliers/contractors of solid wood both in Sweden and Norway, but it seems that there aren't too many dealing with it. I've only READ and heard that Germany is leading in this field, but I don't quite know what to search for or exactly whom to ask. That's why I turned here

For those of you who know a bit about the topic:
-Are there any disadvantages of solid wood? We only read about positive things, but I WANT to read about the negatives too so we can have an overview - if there are any.
-Is there anyone here who has built with solid wood? It would be fun to see pictures and hear about how the process went, from the planning stage to the finished project!
-Supplier/contractor? We would really appreciate it if anyone knows companies that work with solid wood houses!

It also seems that Sweden is a bit more modern and ahead with solid wood than Norway is - at least that's the impression I've gotten. That there are actually more solid wood houses in Sweden than in Norway.

Regardless, I think most of the pictures I've seen of these houses are so incredibly beautiful in some way, blending so nicely with the surrounding nature.

Thank you so much in advance!
Regards,
Sandra

A timber house maybe?

I assume you mean CLT (cross-laminated timber). It has been used quite a lot in Sweden. It's impressive that they have a tolerance of around +- 1 mm on the blocks.
For example, Martinsons, Setra, and Moelven manufacture it.

A log house perhaps?

I assume you mean CLT (cross-laminated). Quite a lot has been built with it in Sweden. It's cool that they have a tolerance of around +- 1 mm on the blocks.
Manufacturers like Martinsons, Setra, and Moelven.

You're probably right that it's called a log house! I tried Googling massive wood and got some search results on that. I know it's called massivt tre in Norway (considering we live here ).

As mentioned, I don't know much about house building, but why is it cool to have a "tolerance of around +- 1 mm on the blocks"?

I'll Google more on log houses and see if I can get more information, thanks!

Now confused.
Log houses have been built for a thousand years. And new ones can be built as well. There are house manufacturers that build in a modern/machine-based way and then there are craftsmen who construct traditionally.

Cross-laminated timber (CLT) is a modern construction method where wood is cross-laminated into large panels that are processed in CNC machines with high precision. These panels or blocks are lifted into place and screwed together.

Not sure which one you're thinking of?

What is difficult is meeting the isolation requirements. Then it becomes expensive.

Check with Isotimber!

We have been living in ours for almost a year now and it works just as well as intended.

They sell a lot to Norway and it meets the insulation requirements without any issues.

Are you perhaps referring to CLT? Cross-laminated timber elements that can be obtained in all possible shapes and sizes. The largest manufacturers in Sweden are Martinssons, Moelven, and Setra. I know some companies that construct and assemble a lot of buildings in CLT and regular Glulam. Send a pm if you want the numbers to some.

Fun to read this, there was a thread not long ago about how it was difficult to meet insulation requirements with wooden walls.
Please share more about the house.

Fun to read this, there was a thread not too long ago here that talked about the difficulty of meeting insulation requirements with wooden walls. Please tell us more about the house

The frame is 30cm Isotimber and 6cm CLT. The exterior is clad with plywood, nail battens, and horizontal glulam paneling. No studs anywhere, so there are no thermal bridges.

I remember the U-value ended up at 0.24.

The energy consumption forecast looks to be around 4500 kWh/year for 257m2 A-temp.

The frame with intermediate floors, trusses, and windows/doors cost approximately 1.3. That's for the house + 65m2 garage.

Umedel, if I remember correctly, ended up at 0.24.

The forecast for energy consumption looks to be about 4500 kWh/year for 257m2 A-temp.

Framework with intermediate floors, roof trusses, and windows/doors cost about 1.3. That's for the house + 65m2 garage.

No studs anywhere? The whole house is basically a stud/thermal bridge? Or have I misunderstood what isotimber is?

 

[Robert-san01]

No studs anywhere? The whole house is just one stud/cold bridge? Or have I misunderstood what isotimber is?

Isotimber can support itself, but the layers are offset so there are no bridges.

 

[Daniel 109]

But can it be called massive?

 

[Robert-san01]

But can it be called massive?

Good question.

It is at least a bit more massive than a regular frame.

The inside is massive, it's CLT.

Must reasonably be traditional log houses being referred to. CLT elements are just a frame (+ insulation) that can be clad with a facade of choice(?). So I assume those houses generally look like any other house?
