What Affects the Cost?
Extension costs in Slough vary significantly based on design complexity, foundation type, and existing property structure. Ground conditions affect foundation work costs; semi-detached and terraced homes may require party wall procedures, adding £500–£1,500. Material quality, whether utilities need relocating, and roof style (pitched vs flat) influence pricing. Local labour availability and Slough's proximity to London increase rates. Planning approval timescales and building control requirements also impact overall project timeline and cost.
Money-Saving Tips
Request multiple quotes from local builders to compare pricing. Consider standard finishes over bespoke designs to reduce costs by 15–20%. Plan extensions during quieter seasons (winter) when builders may offer discounts. Manage groundwork efficiently by clearing the site yourself. Obtain planning advice early to avoid costly redesigns later.
