What Affects the Cost?
Extension costs in Ashford depend primarily on footprint and height—single-storey builds cost significantly less than double-storey projects. Construction method matters greatly: timber-framed extensions are faster and cheaper than traditional brick and block, though both have merits. Local factors include ground conditions, existing structural integrity, and proximity to conservation areas (which require additional approval). Specification choices—finishes, glazing, heating systems—substantially impact the final bill. Design complexity and site access further influence labour costs and timescales.
Money-Saving Tips
Obtain multiple quotes from established local builders—prices vary by 15-25% between reputable firms. Consider timber frame over brick block if budget is tight; plan extensions to avoid listed building restrictions. Schedule work during off-peak months (autumn/winter) when builders may offer discounts. Pre-obtain planning permission yourself to reduce costs by £300-600.
