Anyone Converted the Roof Space of Their Garage

[boysey]

I've got a huge potential space in the roof of my attached garage roof and a need for a decent home office. Has anyone done this and can point me toward any useful web sites>

I can find plenty of sites that has information about converting the whole garage (which I don't want to do) and plenty on loft conversions but guess what I am proposing is a little different.

Would like to try and understand key steps so I can see what is involved from a planning, regulations and cost perspective before I decide to go further with this or ditch it and buikd a cabin outside instead.

Thanks!

The first question you need to answer is whether the walls of the exiting garage are double skin, or single skin with localised thickening by means of piers.

If the latter, you'll quite probably find that they're not strong enough to support the additional storey without further structural work.

I was considering this myself a few months ago. Bloke next door is a builder and his opinion was that it would be too costly for what I had in mind. I would need brick piers, long RSJs, big changes to the joists/purlins etc., and that's before you consider the staircase cost/access, velux windows, boarding, electrics, insulation etc. etc.

He put me off and I looked into garden rooms and was quite pleasantly surprised at the cost & style and the range of accessories including power panels etc.
Found a couple of sites which look promising.

I understood the OP to mean that he just wanted to utilise the existing triangular space.

If it's anything my garage (whch it may well not be) you'll end up in the 'Fink Truss Conundrum' However at least in a garage where the structure is exposed it's possible to support the trusses - I bolted blocks of 4x2 to the central piers so at least some of the load is trnsferred. Hardly NHBC I agree but OK for storage.
