Structural Engineer Devon
Structural engineering for homes across Devon
Devon has a wide mix of homes. Stone cottages in small villages, 1930s semis around Exeter, post-war estates across Torbay and rows of terraces in market towns. Many people contact us when they want to open up a ground floor, convert a loft or build a rear extension.
We design the structure behind those plans.
You get clear calculations, tidy drawings and direct support for Building Control.
Whether you live in Exeter, Torquay, Paignton, Newton Abbot, Barnstaple, Exmouth, Tiverton or a rural village, we provide practical, straight-talking structural design that fits your home and your builder’s style of working.

Common wall-removal jobs in Devon:
- Kitchen and dining room knock-throughs in Exeter terraces
- Larger openings in Torquay and Paignton semis
- Turning dated layouts into open-plan living in Newton Abbot and Exmouth
- RSJ beams above wide garden doors in Barnstaple and rural homes
Residential Projects We Support
We provide clear, direct calcs that match your drawings and answer the questions inspectors normally ask.
RSJ beams and wall removals across Devon
Opening up older layouts is one of the most common requests across the county. Many Devon homes were built with small, closed-off rooms. A simple RSJ can turn two awkward rooms into a single, useful space.
What we check before designing your RSJ:
- Floor span directions in older homes
- Irregular stone walls in villages and rural cottages
- Bearing strength when walls are mixed construction
- Padstone needs and how loads pass to footings
- Moisture and corrosion risks in coastal areas
Loft conversions in Devon
Loft conversions are popular across the county, especially where families want more space without extending the footprint.
Structural elements we design for Devon lofts:
- Ridge beams
- Dormer support
- Stair trimmers
- New joist layouts
- Strengthening to old rafters where needed
Structural calculations Devon
Whatever the project size, you need structural calculations that Building Control can trust. We provide clear, direct calcs that match your drawings and answer the questions inspectors normally ask.
Devon Building Control expectations:
- Well-matched drawings and calcs
- Clear assumptions
- No confusing theory
- Simple sketches
- Straight answers when they query anything
Extensions and renovations
Extensions vary across Devon. Some houses sit on steep plots, others need retaining walls, and some older cottages have shallow footings. We design what you need so your builder can build safely.
Common extension types in Devon:
- Kitchen-diner rear extensions in Exeter and Exmouth
- Side extensions in Torquay and Paignton
- Larger rear extensions in South Hams villages
- Garden rooms on sloping ground around Newton Abbot and Teignbridge
Timber design Devon
Timber is common in many Devon homes, especially older ones. We’re often asked to check spans or upgrade parts of the structure during renovations.
Typical timber issues in the county:
- Mixed joist sizes in old cottages
- Overspanned ceiling joists in older terraces
- Wet or softened timbers in coastal homes
- Dormer framing issues in loft conversions
Subsidence and movement in Devon
Devon has pockets of clay, older foundations and large mature trees close to houses. Some homes show signs of settlement or cracking.
Causes we see locally:
- Clay pockets around Exeter and Newton Abbot
- Stone walls without proper foundations
- Tree roots pulling moisture from the ground
- Coastal ground conditions near Exmouth and Torbay

Notes for Devon projects
Who prepares your structural calculations
Your calculations are prepared by qualified structural engineers with experience in domestic UK projects, including extensions, loft conversions and wall removals. We work with Eurocode standards (EC2, EC3 and EC5) and follow current Building Regulations for England and Wales.
We have over 10 years of experience looking at load paths in typical UK homes, from Victorian terraces and 1930s semis to newer estates and timber-frame builds. Every project is checked by an engineer before the pack is sent out, and we stay available if Building Control needs clarification.

Before we start, you get a clear fixed fee for the job. No extras hidden in the small print.
We offer fixed fees for:
- Wall-removal designs
- Loft conversion beams and joists
- Extension structural packs
- Timber floor or roof design
- Subsidence inspections

“We converted our loft in Torbay. The calcs were quick and Building Control approved them straight away.”
“We live in a small rural cottage and needed advice about movement cracks. SECalcs visited and gave us a clear plan for repairs.”
