How much will a home extension cost in West London? 

As with all estimates, the cost will fluctuate depending on the size of the property and the scale of the project. It is important to remember that the cost will ultimately be determined by the square footage required and you must factor in varying styles of fixtures and fittings in addition to VAT. A typical single-storey extension is usually around £2000 per square metre whereas a two-storey extension can be in the region of £3000 per square metre. Extensions which include bathrooms, kitchens or utility areas can be on the upper end of costings.
