Thanks Thyri. I had thought about the thermal mass aspect with a heater bench at the beginning and had nixed it as being too complicated for a first project,but you're probably right and it's at least  worth reconsidering.  

The room will have one full time occupant and some occasional volunteers passing through.

It does get chilly at night.

Not sure what impact the wind has on interior temperature, but it does make it colder at night. It generally comes from the northwest. There's a vinyard directly to the west and we need the visibility on the northern side, so no chance of a windbreak.

Haven't checked the valley yet for clay, but I may end up bringing some in -apparently it's a waste product from the water company?

Hi all, new member and relatively new permie. I've recently been asked to build a small structure with an interior of 4m x 5m to be used as a sleeping space. This will be the first building for which I design and lead construction. The lot selected is flattish and directly on limestone bedrock. There are tons of rocks in every size around here, but not much in the way of other resources. We have very strong winds out here, 0% humidity in the summers with temperatures of up to 39°C.  I haven't been here in the winter yet, but I understand that it can get pretty cold (down to - 5°C) with up to 30cm of snow, although above freezing is much more usual.

Frankly, I'm a little at a loss in terms of where to start. I'd like to build stone walls directly on the bedrock and lay a wood floor, but am struggling with what kind of insulation to use and what to do about the roof. From what I understand, light straw may be my best insulation option,  but I'd prefer something more efficient. I prefer to design around the materials rather than trying to work against them, so I have to get these down before actually getting started.

Any and all input is appreciated!
