What Affects the Cost?
Extension costs in Littlehampton depend on footprint size, storey height, building complexity, and material quality. Foundation type (clay soil common in the area), proximity to neighbouring properties, and existing building condition all influence pricing. Planning permission requirements and Building Regulations compliance add £800–£1,500. Material costs fluctuate; brick, render finishes, and roofing specifications significantly impact budgets. Labour costs reflect local trade availability and project timescales.
Money-Saving Tips
Obtain multiple quotes from local builders to compare genuine market rates. Consider phased building to spread costs; plan extensions during quieter winter months when builder availability increases. Simplify design elements—standardised roof angles and material selections reduce complexity and costs without sacrificing quality.
