House extensions in Bath, Trowbridge and across BANES — from a side-return on a terraced street to a double-storey rear build. We handle planning drawings, structural steel, groundworks and Building Control in one fixed-price contract, so the number you sign is the number you pay. Single-storey builds typically run 10–14 weeks; double-storey 16–24 weeks — both confirmed at quote, not discovered mid-build.
Southdown's mid-century estates — including the Poets' Corner streets named for Chaucer, Milton and Shelley — offer solid, well-built housing that, with the right structural investment, can be transformed into genuinely spacious family homes. The typical plot sizes allow for meaningful rear extensions; the roof profiles on many properties suit dormer loft conversions well; and the relative simplicity of the construction means structural interventions are often more straightforward than in Bath's older terraced stock. Our team works efficiently with these property types, delivering extensions and conversions that maximise the permitted development opportunities available and deliver strong returns on investment.
