In general it can be said that larger buildings with simple, rectangular, regular floor plans and elevations will be less expensive per sq.m. of floor area than smaller, complex shaped, curved or angular buildings. Economies of scale apportion fixed overheads to a larger extent of productive space. Simple setting out and buildable solutions encourage greater plant use and generate higher productivity and less waste. Complex layouts and details are slower to assemble and may involve a number of trades with a consequent greater risk of mistakes and defects. The degree of compartmentation and repetition will also affect the overall cost of the work. New building work is considerably cheaper than work of a repairing nature or work in existing buildings. Single storey structures tend to be more costly than buildings up to three storeys high, beyond which point they become progressively more expensive.
Insulation is an area where some look to save. Because after all, the reasoning goes, you cannot see the insulation in the walls or the attic once it is complete and who wants to spend money on things you can not see in your new home? Do not make this mistake. Not only will it translate into a lifetime of higher monthly energy bills, but it will lead to everyday discomfort with the home feeling too cold in winter and too hot in summer.
