If you do not know exactly what an Architect does, what Planning and Building Approval consists of, what a set of documents look like and how much Architects charge, or what the approximate costs of designing and building using an Architect are then you should spend some time looking through the Resources section of my Website. Alternately just give me a call & I can talk you through the process.
If you are a Graduate Architect or Student of Architecture then there is also something for you. My blog about running a SOHO Architectural practice and Documentation system including AutoCAD template drawings have helped many get a start in a very competitive workforce.
