ARCHITECT-LED DESIGN & BUILD
- Leave everything to an experienced local architect — minimal hassle, maximum precision and control.
- Designed for complex, planning-sensitive, or technically challenging properties, including conservation areas, tight roof geometries, or unusual structures.
- Your Professional Partner Architect manages the entire process — design, planning strategy, insulation compliance, and Building Control — working closely with an Approved ecoTrus Installer to deliver a fully coordinated, ready-to-finish loft space.
- All planning permissions, restrictions, and conditions are carefully assessed and managed, ensuring your design meets local authority requirements while maximising usable space.
- Insulation specifications are fully coordinated to meet current Building Regulations, including U-values, thermal continuity, and condensation control — removing risk and guesswork.
- You benefit from one coordinated team, one clear process, and one transparent cost, covering design, system, installation, and certification.
