About Bourdon Hill
Why Choose Bourdon Hill for Your London Property?
Bourdon Hill is a specialist structural design consultancy based in London. We provide Basement Impact Assessments (BIA), structural design for luxury residential refurbishments, temporary works design, and technical planning support for architects and homeowners across Greater London.
Since 2009, we've completed over 800 projects across Greater London, creating 12,000m² of new living space. Our local expertise means we understand London-specific planning regulations, conservation area policies, and the structural challenges of Victorian terraces, Georgian townhouses, and modern developments.
As design-led structural engineers, we respect the architectural intent. Our goal is to provide the hidden structural calculations and precise steelwork (RSJ) detailing that makes open-plan living and expansive glazing possible — without compromising the design.

For Design Professionals
Design-Led Engineering: The Architect's Technical Partner
As a design-led structural engineering consultancy, we understand that our job is not to compromise your architectural vision, but to engineer the reality of it. We are not building surveyors looking for defects; we are design engineers focused on creation, spatial optimisation, and structural elegance.
How We Support Your Practice
Preserving the Aesthetic
We know that a bulky column or an oversized beam can ruin months of careful spatial planning. We specialise in the hidden calculations—detailing slimline steelwork (RSJs), integrating structural glass, and hiding load-bearing solutions within ceiling voids to protect your design intent.
Unlocking Planning Permission
London boroughs are increasingly hostile to complex developments. We take the technical red tape off your desk. From delivering stringent Basement Impact Assessments (BIA) for Westminster to drafting the Construction Method Statements (CMS) required by RBKC's Policy CL7, we provide the robust documentation that planning committees demand.
Proactive "Yes, And" Engineering
Architects waste too much time with engineers who simply run a calculation and say, "It fails." If a proposed layout presents a structural challenge, we do not just flag the problem; we bring three viable, cost-effective structural solutions to the table to make it work.
