Parts of Carshalton, Sutton, and several Surrey towns lie within conservation areas — we advise on planning requirements at the free site assessment before any commitments are made.

Our Joinery Construction Services
Loft Conversions & Roof Carpentry
Transform wasted attic space into a master suite, office, or playroom.
- Structural timber framing – Reinforced floors and load-bearing walls.
- Dormer windows – Maximise light and headroom.
- Staircase integration – Space-saving spiral or alternating tread designs.
- Velux and skylight installation – Full structural opening and weatherproofing included.
Timeline: A standard loft conversion on a 3-bedroom semi-detached takes 6–8 weeks from start to finish. This includes structural frame, insulation, boarding, windows, and staircase. Planning permission, where required, adds time before work begins — we advise on this at the free site assessment.
House Extensions & Orangery Builds
Expand your living space without moving.
- Single and double-storey extensions – Brickwork, timber frames, or glazed designs.
- Seamless integration – Match original features like skirting, cornices, and architraves.
- Underfloor heating prep – Subfloor installations for tiles, wood, or vinyl.
- Conservation area compliance – We advise on what is and is not permitted under local planning rules before any work starts.
Timeline: A single-storey rear extension typically takes 8–12 weeks. Double-storey extensions run 12–16 weeks. Timelines depend on groundworks, materials, and whether planning permission is required.
Partition Walls & Internal Remodelling
Open-plan or zoned – your choice, our craftsmanship.
- Acoustic partition walls – Ideal for home offices or duplex conversions.
- Pocket door systems – Save space in tight layouts.
- Load-bearing solutions – Steel beam installations supported by structural timber.
- Period feature matching – New partitions finished with matching skirting, architrave, and coving to blend with the existing room.
Timeline: A standard partition wall takes 2–4 days. Load-bearing wall removal with steel beam installation runs 3–5 days including structural engineer sign-off.
Materials & Structural Standards
We use materials specified to meet UK Building Regulations and suited to each property type:
- FSC-certified structural timber – C16 and C24 graded for all load-bearing applications.
- Steel beams (RSJ) – For load-bearing wall removals, specified by a structural engineer and included in our fixed-price quote.
- Insulation – Kingspan, Rockwool, or PIR boards depending on application and U-value targets.
- Finishing joinery – Skirting, architrave, and coving matched to existing profiles using solid timber or moisture-resistant MDF.
All structural work is fully insured and compliant with UK Building Regulations Part A (Structure), Part B (Fire Safety), and Part L (Energy Efficiency).
From Planning to Completion
We manage the full project — from planning advice through to final finish. Here is how it works:
- Step 1 — Free Site Assessment – We visit, assess the structure, discuss your ideas and budget, and confirm whether planning permission or building regulations approval is required. No charge, no obligation.
- Step 2 — 3D Architectural Visuals – See your extension or conversion in photorealistic detail before any commitments are made. We work with local architects to produce drawings for planning submissions where needed.
- Step 3 — Material Sourcing – Sustainable FSC-certified timber, structural steel, and insulation specified to meet Building Regulations and your project requirements.
- Step 4 — Build & Finish – Our team coordinates carpenters, electricians, and plasterers. One point of contact throughout. Fixed price agreed upfront — no surprise costs.

❓ FAQs — Structural Joinery & House Extensions
- Q: Do you handle planning permission applications?
A: Yes — we partner with local architects to manage the full planning process. We advise at the free site assessment on whether your project needs permitted development approval or a full planning application, particularly for conservation areas across Carshalton, Sutton, and parts of Surrey. - Q: How long does a loft conversion take?
A: 6–8 weeks for a standard 3-bedroom semi-detached. This covers structural frame, insulation, boarding, dormer windows, and staircase integration. Planning permission, where required, is arranged before work begins and is not included in the build timeline. - Q: Can you match period features in new extensions?
A: Yes — replicating original features is one of our specialisms. We match skirting profiles, architraves, cornices, and brick bonds so new additions blend seamlessly with the existing structure. We take samples from the existing property before ordering any finishing joinery. - Q: Do I need a structural engineer for a load-bearing wall removal?
A: Yes — and we organise this as part of the project. A structural engineer specifies the steel beam size and provides calculations for Building Regulations sign-off. The cost is included in our fixed-price quote. - Q: What is included in the 10-year structural warranty?
A: The warranty covers all structural carpentry — timber framing, load-bearing elements, and roof structure. It is fully documented and transferable if you sell the property. - Q: Can you work in conservation areas in Surrey?
A: Yes — we regularly work in conservation areas across Carshalton, Sutton, Guildford, and Oxted. We advise on what is and is not permitted at the free site assessment and can prepare supporting documentation for planning submissions where needed.
