Structural design, analysis and calculations for residential and commercial projects — clear drawings, fast turnaround, and one point of contact from quote to sign-off.
The five things we do most, across the residential and commercial sectors — each delivered as a signed pack of calculations and drawings.
Full structural design packages in line with current British Standards — foundation systems, superstructure frameworks, lateral stability provisions and load path optimisation. Geotechnical data, material specifications and analysis are brought together so the design is compliant, cost-efficient and built to last.
Assessment, design and certification of changes to load-bearing and non-load-bearing elements. We survey the structure and calculate load redistribution, member sizing and stability retention — wall removals, beam and column insertions, floor strengthening and underpinning, with connection details and installation sequencing.
Designed to meet the structural and fire safety requirements alongside thermal and acoustic performance. We assess the existing roof for capacity, specify new steel or timber members, and detail ridge, purlin and joist reinforcement — including dormers, roof openings and staircase installations.
Rear and side extensions designed to the relevant British Standards and local planning constraints: foundations (strip, raft or pile), wall and roof load calculations, lateral stability, and steelwork or engineered timber specification. We address differential settlement, thermal bridging and the interface with the existing fabric.
Structural surveys, feasibility studies and inspection reports for owners, buyers and managing agents — crack and movement analysis, defect diagnosis, condition assessments and basement impact studies. Each one sets out what we found, what it means and what to do next, in language a non-engineer can use.
Three stages, each resting on the one before it. No stage begins until the load beneath it is understood.
Send drawings, photos or a sketch. We come back with exactly what's included, what isn't, and a fixed fee — usually within a few hours.
Loads traced from roof to foundation, members sized to the Eurocodes, and every assumption written down so it can be checked.
A signed calculation pack and drawings go to you and Building Control — then we answer your builder's questions while the work is on site.
Enstruct Consulting was founded in London in 2024 to help clients feel supported from the very first conversation — whether that's strengthening an existing home, creating more space with a loft or extension, or bringing an entirely new building to life.
We're here to solve problems, not create them — to make the process smooth, the outcome dependable, and the experience genuinely positive. No drip-fed invoices, and no calculation pack that leaves your builder guessing.
If yours isn't here, ask — a straight answer costs nothing.
If you are removing or altering anything that carries load — a wall, a chimney breast, a roof member — Building Control will ask for calculations from a qualified engineer before they sign the work off. It is usually cheaper to have them done before the builder starts than to correct assumptions afterwards.
Most domestic packages are issued three to five working days after the scope is agreed and drawings are received. If you are up against a Building Control or start-on-site date, say so in your enquiry — urgent work can often be turned around sooner.
Architectural drawings if you have them, or clear photographs and rough dimensions if you don't. Tell us what is being removed or added, roughly when the work starts, and whether Building Control has already been approached.
Yes. Once a design is issued we will talk your builder through connection details, substitutions, or a site condition that differs from the drawing. Ask at enquiry stage and we will set out exactly what the fee covers.
Enquiries come straight to us, not to a call centre. Send the details and you'll hear back the same working day.
Thanks — we'll come back to you by email with a scope and a fixed fee, usually the same working day.
