Local knowledge of Orpington's historic centre and its suburban streets, from first feasibility conversation through to a finished project.

Living and Building in Orpington

Orpington grew around The Priory, a building of 15th-century origins that later housed Bromley's museum, and around its parish church of All Saints, before the railway turned it into a suburban town.

Diagram X brings AEC (Architecture, Engineering and Construction) together for homeowners across the interwar and post-war houses that make up most of the area, one of the borough's busiest housing markets.

Planning in Orpington

The Broomhill conservation area and the listed Priory and church add heritage consideration near the centre, while most of the suburb is typical interwar and post-war housing.

Permitted development rights should be checked for the exact property, as controls vary between streets.

Refurbishing in Orpington

Across the area's interwar and post-war houses, most interiors have had little meaningful updating in decades, so refurbishment starts from open, light-filled layouts and modern performance.

A genuinely worthwhile period feature earns its place when retained, but a confidently modern result inside is always the starting assumption.

Construction in Orpington

Consistent semi-detached streets, generous rear gardens and some Green Belt edges shape what extensions and loft conversions can achieve, alongside the usual party wall agreements.

We plan for these from the outset, so Orpington's suburban streets and its individual homes are both well served.
