I really want a garden room/log cabin. We've got a maximum of 3m wide by 7m long. Start to finish we have a budget of about £15-20k. I want it as an artist studio all year round so i need it completely weatherproof. I'm wondering what the best way to go about it is - a wooden log cabin with insulation or getting someone to build a brick structure? I can't have anything that needs foundations so was looking at a concrete base. And how realistic is my budget? I don't really have time to do any of the work myself so ideally i want someone to do it all for me. The log cabin im looking at is about £6.5k.
