The Build cost we refer to is currently £2,200/sq.m plus VAT (March 2023) and is for the fabric of the completed building with standard finishes and elements such as foundations, walls, roofs, windows, doors, architraves, skirtings, lighting and electrical circuits, heating and ventilation in the Cheshire area. This basic build cost excludes kitchens, bathrooms, and feature items such as fireplaces, feature light fittings, smart home technology, underfloor heating and luxury floor and wall finishes.  For a luxury new build, including the kitchens, bathrooms and finishes, you should budget for a minimum of £3,000/sq.m. New builds have a lower VAT rating than standard, 0% for labour and most materials – we can advise on this. Extensions, including loft conversions – depending on the existing house structure, garages and out buildings vary from the basic and luxury build cost, listed above.
