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.

    Pricing notes

    Mid-century structural methods, estate road access and permitted development envelope assessments are addressed proactively at every Southdown project — the simpler construction often makes these the most cost-effective extensions we build.

    Who lives here

    Established owner-occupier families, many of whom have watched the estate mature for decades and now invest in extending rather than moving.
