Construction technique for this outdoor building?

[flanajb]

I would like to do something like the following in the garden, but am unsure how best to achieve it.

I assume the slab would be the usual block with damp course and a concrete slab filled with DPM, but it is the construction of the walls that I am trying to understand.

Looks like studding with a cedar clad exterior to me. It is possible that there is a concealed steel portal frame within the studding to give extra strength to the area around the doors. I would just use 6" x 2" studding with a breathable membrane with the cedar clapped on the outside, internally either plasterboard or whatever wall cladding you fancy. Solid header from the door openings up to the roof would keep it all nice and strong.

I've been looking into this myself as I have something similar to do for a customer later in the year. Walls generally seem to be a WBP skin around CLS studwork, with the voids filled with Kingspan/Celotex. These are then clad with Shiplap/T&G/whatever on the outside, and drywalled/plastered on the inside.

Whether you need a slab or not seems to depend on the state of the ground - these guys show their construction process in broad terms - a bit light on detail, understandably, and there's a time-lapse video of a construction here

It's certainly a lot lighter-weight than you might think...

Yes timber framing and stud walls is the way I would do it. Timber floor also with insolation under it. You wouldnt need a slab but maybe short foundations or even just pins where support is needed.

Google SIP buildings. Structural Insulated Panels.
I've just sketched up my next workshop and it's going to be built this way. Very quick and very energy efficient. You can have entire houses built this way and, indeed, it is common in Germany, Scandinavia and North America. It arrives flat-pack on the back of a lorry.

If you do google, you will soon find a familiar name. Mark Ramuz, late of Woodworker Magazine, is now running a company called garden2office.

I've sent my sketch to a couple of companies, including Mark, so we'll see what my sanctum sanctorum is going to cost me.

I too did a bit more research and came to the conclusion that a neat solution would be to hire a post borer and concrete into the ground a series of pillars with a heavy duty 60mm threaded bar. You could then use the threaded bar and nuts to level a suspended timber base with which to build the rest of the structure on. I have found a firm that sells 60mm threaded bar which when concreted into the ground should make adequate pillars to build on.

As mentioned already, a concrete base is overkill and costly too

Flan, have a look at this:

Have a look at this set of photos. Can't remember now if it was posted by a member here or on another forum

Thanks for that link. Some great photos showing the whole process. I think I may download those and keep for reference

Perhaps look at the Walter Segal house. Self build design with minimal foundations.

Second Jacobs suggestion. Walter Segal had ground breaking ideas which worked. Best wishes to you all.
