A typical single-storey house extension may take approximately three to five months to construct, although the timeframe varies according to its size, complexity, ground conditions and finishing requirements. More substantial extensions or projects involving extensive structural work can take longer.
Planning permission, architectural drawings, structural calculations and Building Regulations considerations may also add time before construction begins.
At Adam Hurst Construction, we take a structured approach to building house extensions in our Hampshire service area, coordinating trades, materials and construction stages to support efficient project delivery.
