Wiltshire.
Architectural surveys, planning drawings and Building Regulations services across Salisbury, Trowbridge, Warminster, Westbury and selected surrounding areas.
Wiltshire homes.
Thoughtfully drawn.
For extensions, loft conversions and changes to existing homes across Wiltshire, we prepare accurate drawings and explain the planning or Building Regulations steps that follow.
Wiltshire Council’s validation checklist sets out the information needed for different applications. We check the current requirements for your proposal and prepare the relevant drawings. For a historic or rural property, materials, windows, roof form and the surrounding context may need particular care.
Services include measured surveys, house-extension and loft-conversion drawings, Certificates of Lawfulness, planning applications and technical Building Regulations packages.
