​

At The Architectural Design Syndicate, our structural engineering services are an integral part of our full-spectrum design and construction consultancy. We provide reliable, compliant, and buildable structural solutions for residential, commercial, and mixed-use developments across the UK.

Whether you're planning a home extension, loft conversion, new-build, or a commercial refurbishment, our qualified structural engineers are here to ensure that your project stands strong—literally and legally.

​

What We Offer

​

Our structural engineering services are tailored to suit the scale, complexity, and specific requirements of your project. We offer:

✅ Structural Calculations & Load Assessments
For beams, floors, walls, roofs, and foundations—ensuring your structure complies with British Standards and Eurocodes.

✅ Steel Beam Design (RSJ)
Commonly used in extensions and open-plan designs, we specify the right beam size, placement, and support details for Building Control approval.

✅ Foundation & Slab Design
Including pile foundations, raft slabs, trench fill, and pad footings—tailored to ground conditions and structural loads.

✅ Structural Drawings
Clear, construction-ready CAD drawings for use on-site and for submission to Building Control and contractors.

✅ Retaining Wall & Underpinning Design
Where stability, excavation, or neighbouring structures are factors, we engineer the best retaining or support system.

✅ Site Visits & Structural Reports
When needed, we offer structural inspections, feasibility assessments, and engineer-signed reports for insurers or mortgage lenders.

✅ Temporary Works Design
Including propping, needling, and sequencing advice for safe demolition or phased construction.

Our engineers calculate the appropriate solutions, factoring in building regulations, safety, materials, and cost-efficiency.

​

Step 3: Calculations & Drawings

We produce detailed structural calculations and CAD drawings—suitable for Building Control submission and for your builder to work from.
