We advise on permitted development vs. full planning and handle submissions.
RSJs, load paths, and openings set out by qualified engineers; we build once, build right.
Materials and profiles matched so the extension looks like it has always been there, or deliberately modern if you prefer contrast.
Phasing to limit disruption, dust management, and safe segregation of work areas.
Structural integrity and integration
Engineered openings, correctly sized steels, and load paths that protect the existing fabric. New work ties in cleanly so the finished space feels solid and seamless.
Thermal and acoustic performance
Upgraded insulation, airtight detailing, and acoustic layers where needed. Warmer rooms, quieter living, and lower energy use from day one.
Daylight and glazing
Thoughtful window and door sizing with considered orientations and sightlines. Solar control and ventilation routes that balance light, privacy, and comfort.
Heating and smart controls
Underfloor heating or correctly sized radiators with zoned control. Efficient boilers or low temperature systems commissioned for even, responsive warmth.
Kitchens, bathrooms, and utilities
Service routes planned early for clean installations. Durable carcasses, quality hardware, waterproofing in wet areas, and easy maintenance finishes.
Compliance and approvals
Clear drawings for planning or permitted development and Building Regulations coordination. Party Wall guidance where applicable and documented inspections.
Programme, protection, and handover
Realistic scheduling with live in phasing, dust control, and protection to unaffected areas. Handover pack with manuals, certificates, and care guidance.
Do all extensions need planning permission?
Many fall under permitted development; we’ll confirm after a survey.
How long does a typical extension take?
10–16 weeks depending on size, structure, and finishes.
