Architectural drawings in Balham

Balham sits in the SW12 postcode within the London Borough of Wandsworth, positioned between Clapham Common to the north and Tooting to the south. Its broad, tree-lined streets of generously proportioned Victorian and Edwardian terraces make it one of south-west London's most sought-after family neighbourhoods — and one of its busiest for residential architectural work.

Large terraces with extension potential: Balham's terraces are notably wider and deeper than those in many neighbouring areas, offering significant potential for rear extensions, side-return infills, and loft conversions. Many properties have rear gardens of 15-20 metres, giving ample scope for single or even double-storey rear extensions within Wandsworth's planning policies.

Balham Conservation Area: The Balham Conservation Area covers key streets around Balham High Road, protecting the Victorian commercial and residential character. Within the conservation area, Article 4 Directions require planning permission for external alterations including replacement windows, front doors, and boundary walls. Our MCIAT-chartered team prepares applications that respect the conservation area's character.

Loft conversions: Balham's Victorian and Edwardian terraces typically have generous roof spaces well suited to dormer loft conversions. Outside the conservation area, rear dormers can often be built under permitted development. Within the conservation area, planning permission is required but Wandsworth Council is generally supportive of well-designed rear dormers. We survey the roof structure and advise on the best approach for each property.

Period features and design sensitivity: Many Balham properties retain original Victorian and Edwardian features — bay windows, decorative brickwork, tiled paths, and ornate plasterwork. Wandsworth Council expects new extensions and alterations to complement these features. Our designs balance contemporary functionality with sensitivity to the existing period character.
