Hello folks. I am writing from Canada so I am not sure if the sq. ft. price is calculated the same there. We have been in the residential custom home market for 28 years. When the sq. ft. price first became very popular was in the days of building what we fondly referred to as a "BC Box" A basic rectangle with either two or three bedrooms ups, one bathroom up and family room and secondary bedrooms and bathroom down. A split entry. Very basic. The consumer didn't have the huge variety of choices for finish etc. that we do now so really it was pretty realistic. Now... not so much. Home come in many shapes, size, variables in roof design affecting trusses, more stringent building code, and the list goes on. Personally in our company we dislike the use of the sq. ft. price, here is why. Each builder will consider in his or her sq. ft. price what they feel should be included, there is no industry standard. For some (like ourselves) include the driveways, sidewalks, excavation, bascially everything to get you from excavation to turn key into a newly built clean home. The definition for the homeowner is not always the same as the builder you speak to. It is VERY important when questioning someone regarding a sq. ft. price to find out what is included within that price. Clarity and transparency is huge when having someone build you a home. Make sure that you are not only using a sq. ft. price to choose a builder, be sure to use your senses when interviewing builders. Gut feeling as to how you feel you could work with this individual is a greater guide than the sq. ft. price is. If you feel the builder is being open and honest with you and will talk through the process with you, then you know your new Home will be handled the same way. You will be financially and emotionally "married" to that company for 5 months or so while you build, so be sure there is trust and a sense of assurance that you and your money are in good hands.
