Factors affecting an extension’s cost

The major factors that affect the cost of an extension include:
– How many floors?
– Rear, side, or wrap around?
– Conservatory of orangery?
– Basement?
– Roof-space or extra floor?
– Method of construction?
– Cladding?
– Personal involvement?
– VAT?

At ICE Arch Ltd we will be happy to discuss the choices and implications, and we work with a number of quantity surveyors who will cost specific proposals, but before contacting us you may wish to do you own research.
