Why Bromley

Local Architectural Expertise

Navigating Bromley's Architectural Diversity

Bromley’s diverse housing stock presents unique structural considerations. The borough features a significant number of large inter-war semi-detached and detached houses in areas like Bickley and Petts Wood, often with hipped roofs ideal for complex loft conversions. In Beckenham and Penge, Victorian and Edwardian terraces require careful assessment for rear extensions and basement works, managing party wall implications and original foundation integrity. Chislehurst and Keston are known for their spacious plots and detached properties, where ambitious single and double-storey extensions are common. Many of these areas fall within conservation areas, such as the Chislehurst or Keston Park Conservation Areas, demanding designs that are sensitive to the established architectural character while delivering modern, functional living spaces. Our structural approach is tailored to these specific contexts.

Bourdon Hill is a London-based residential structural engineering firm with chartered IStructE and ICE engineers who specialise in the building types found across Bromley. Read more about our structural engineering services or explore our Structural Digest for expert guidance.

Local Planning Expertise

Navigating Bromley Planning

Planning and Structural Design in Bromley

Navigating Bromley Council’s planning requirements demands a clear understanding of its Local Plan and Residential Design Guide SPD. The council places a strong emphasis on protecting the borough's predominantly suburban character, particularly within its 25 conservation areas. Policies often restrict the scale, massing, and materials of extensions to ensure they remain subordinate to the original dwelling. For instance, double-storey rear extensions on semi-detached properties require careful design to avoid unbalancing the pair. In areas like Bickley Park, specific design codes apply. Our structural designs are developed from the outset to align with these policies, providing your architect with the robust technical information needed to justify the proposal to planning officers and demonstrate compliance with Bromley’s specific residential design standards, smoothing the path to approval.

Our role is to provide the essential structural calculations and drawings that form a critical part of your Building Regulations application. While your architect leads on planning permission, our designs are informed by Bromley's policies to ensure feasibility. We produce clear, detailed structural information that demonstrates the safety and integrity of the proposed works, from foundation plans for a new extension to steel beam calculations for internal wall removals. This robust documentation gives Bromley’s Building Control department the confidence to approve your project for construction.
