Planning permission drawings, loft conversions, and extensions for Eltham's 1930s semis and suburban houses. MCIAT chartered, fixed fees, Greenwich planning expertise built in.
Eltham sits in the SE9 postcode within the Royal Borough of Greenwich. The neighbourhood's tree-lined avenues of 1930s semi-detached houses, combined with good schools and green spaces, make it one of south-east London's most popular family areas — and one where demand for residential extensions and loft conversions is consistently high.
1930s semi-detached houses: Eltham's inter-war semis are ideal candidates for hip-to-gable loft conversions, single-storey and two-storey rear extensions, and side extensions. The typical hipped roof can be squared off to create a full gable, then a rear dormer added to create a generous loft room. Under permitted development, these works can often proceed without planning permission.
Eltham Palace context: Properties near Eltham Palace and its grounds — a Scheduled Ancient Monument — may face additional planning scrutiny. English Heritage consultation may be required for works affecting the setting of the palace. Our team assesses each site's constraints before committing to a design.
Suburban character: Greenwich Council is mindful of preserving Eltham's suburban character. Extensions that are overly dominant or materially inappropriate may face objections. We design schemes that complement the existing 1930s aesthetic while delivering modern living spaces.
Permitted development: Most Eltham properties outside conservation areas enjoy full permitted development rights. We confirm eligibility, prepare building regulations drawings, and manage the prior notification process where required.

Start a free quoteYes, hip-to-gable loft conversions are very popular on Eltham's 1930s semis. Under permitted development, these can usually proceed without planning permission. The hipped roof is squared off to create a gable wall, with a rear dormer added for additional headroom. We survey your roof and confirm eligibility.
Under permitted development, semi-detached houses can build single-storey rear extensions up to 6 metres without planning permission (subject to prior notification). Two-storey rear extensions up to 3 metres are also possible under PD. We confirm the maximum achievable for your specific property.
