I feel that choosing a contractor is also a highly personal thing. Some people look for the lowest cost and can live with lower finishing standards. Others requires a lot of attention to detail. Material quality also differs greatly. Cost of construction goes up every year so comparisons to house built a few years ago is moot. Arcitect cost is different as well as an architect with innovative design and ideas will not cost the same as a cookie cutter design. At the end of the day the best thing to do is set a budget . Allow for 10 to 20 percent allowance and select architect, contractor and rest based on a realistic selection process. I think cheap and good almost never exist here. Value for money is the key and value is a highly individual thing.
