House Refurbishment vs Home Extension: Which Adds More Value?

Extensions typically add more property value per pound spent because they increase floor area. Refurbishment upgrades quality and finish without adding footprint. Combining a refurbishment with an extension typically produces the highest returns — the extension delivers square footage while the refurbishment ensures the whole property looks and functions as one integrated home.
