Absolutely !!!! Best advice is do as much as you can yourself, drawings, planning application, building regs, project manage, negotiations, two and a half years of pain with a full time job as well, long days and nights, no social life to speak of, loads of research before hand so you know what to expect and have a budget, all planned out and stick to it 100%, we did and it worked a treat, starting our next two once planning is agreed !!!!
