Who we are

Your local Structural Engineer — approachable, thorough, and on your side.

We are a chartered structural engineering practice based in Milton Keynes, working with homeowners, architects and builders across Buckinghamshire, Bedfordshire, Northamptonshire, and North London boroughs including Barnet, Enfield, and Harrow.

Whether you’re planning a rear extension, knocking through walls, converting your loft, or buying a property with concerns, we provide the structural engineering expertise to keep your project safe, compliant, and moving forward — without the jargon.

What we do

Residential Structural Engineering services

01

Load-Bearing Wall Removal

Thinking of opening up your ground floor? We assess whether walls are load-bearing, specify the right RSJ or steel beam, and provide full calculations for building control — so your builder can get on with the job.

02

House Extension Structural Calculations

Single-storey, double-storey, or wrap-around — we provide the structural design and calculations your architect and builder need to get your extension built safely and sign-off ready.

03

Loft Conversion Structural Engineer

Loft conversions involve complex load redistribution. We design structural solutions for Velux, hip-to-gable, and dormer conversions, including steel frame design, floor beam sizing, and party wall considerations.

04

Structural Surveys & Reports

Cracking in walls, subsidence concerns, or a mortgage lender requiring a structural report? We carry out thorough inspections and provide clear written reports explaining our findings and recommendations.

05

Foundation Design

Extending into poor ground or onto a tricky site? We carry out ground assessments and design appropriate foundations — strip, pad, or piled — factoring in the local soil conditions of your specific area.

06

Building Regulations Support

We prepare structural calculations and drawings for your local building control — Milton Keynes Council, Harrow, Luton, Barnet, Enfield, and more. Our submissions are accepted first time, keeping your project on schedule.

How it works

Simple, transparent, straightforward

Step 01

Tell us about your project

Send us a brief description and any drawings you have. We’ll respond the same working day with initial guidance and a fixed-fee quote.

Step 02

Site visit or remote assessment

Where needed, a chartered engineer visits your property to take measurements, assess the structure, and identify any specific site considerations.

Step 03

Structural calculations & drawings

We produce a full calculation pack and any supporting drawings — ready to submit to building control or hand straight to your builder.

Step 04

Ongoing support

We’re available throughout your build for any follow-up questions from your builder or building control. We don’t disappear once the paperwork is done.
