Taking an extension from an initial idea to site-ready plans requires more than just drawing walls—it takes full-scope technical preparation. 🏡⚒️
For this proposed two-storey rear extension project in Scarborough Road, Pontypridd, our team delivered a complete end-to-end design and compliance package, including:
✅ Planning Drawings & Layout Optimisation: Tailoring ground and first-floor layouts to maximise living space, light, and functional room design.
✅ Building Regulations Approval: Detailed technical section drawings covering structural insulation, thermal performance calculations (U-values), and fire protection compliance along property boundaries.
✅ Structural Engineering & Roof Design: Full structural specification for load-bearing beams, joists, and pitched roof structure with valley gutters.
✅ Party Wall Agreements & Boundary Checks: Navigating shared boundary details and party wall requirements with neighbouring properties from the outset.
Whether you are planning a single-storey kitchen diner or a full two-storey home expansion in RCT or South Wales, having your engineering, planning, and regulations handled under one roof saves time, avoids costly revisions, and keeps your build moving smoothly.
