Why Croydon

Local Architectural Expertise

Designing for Croydon's Architectural Diversity

The London Borough of Croydon presents a rich tapestry of residential architecture, demanding a nuanced approach to structural design. The northern parts, like Thornton Heath and West Croydon, are dominated by Victorian and Edwardian terraces, where rear extensions and loft conversions are common. Further south, in areas like Purley, Coulsdon, and Sanderstead, the landscape shifts to larger 1920s and 1930s semi-detached and detached houses, often with generous gardens ideal for substantial extensions. Our structural designs respect this diversity, whether it's specifying a box frame for a period property or designing a steel frame for an open-plan layout in a more modern home.

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

Navigating Croydon Planning

Navigating Croydon Council Planning Policies

Navigating Croydon's planning landscape requires a clear understanding of the Croydon Local Plan 2018 and its associated Supplementary Planning Documents, particularly the Suburban Design Guide. The council places significant emphasis on ensuring new extensions and alterations respect the character and scale of the existing property and the wider street scene. For terraced houses, this often means careful consideration of rear extension depth and height to avoid a 'terracing' effect. In areas with larger semi-detached homes, policies focus on maintaining adequate garden space and preventing proposals from appearing overly dominant. Within Conservation Areas such as Park Hill or the Webb Estate, material choices and design details are scrutinised to ensure they preserve or enhance the area's special character. Our structural designs are developed with these constraints in mind, providing a solid foundation for a successful planning application.

"Bourdon Hill provided a very clear and comprehensive set of structural drawings for our side-return extension. Their engineer was pragmatic and responsive, offering a sensible solution that our builder found easy to work with. The whole process was straightforward, and they were a great help in getting our plans through Building Control."
