Architecture / June 12, 2018 /
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.
Many people will choose a new home because they want to be as maintenance-free as they can. They do not want the headache or hassle of failing systems. But when you choose lesser-quality finishes in appliances, tile, flooring, roofing and windows to achieve size, these items, too, will fail sooner than a higher quality item.
