Design and Planning
Expert Architectural Design & Planning Support for Your Project
Every successful renovation or extension begins with accurate design, detailed drawings and a solid planning strategy. At Select Casa, we work closely with our trusted architect and structural engineer to provide full design and planning support — ensuring your project is compliant, well-planned, and technically sound before construction begins.
From concept ideas to detailed working drawings, planning applications and building control liaison, we streamline the entire design phase so you can move forward with confidence.
Our Design & Planning Services
Architectural Drawings
Clear, precise and professionally prepared drawings that form the foundation of your project. Ideal for extensions, conversions and full refurbishments, they capture every detail needed for accurate costing, planning and construction.
Planning Applications
We prepare and submit all necessary documents to your local authority, including Design & Access Statements, site plans, elevations and technical notes. Whether your project requires full planning permission or falls under Permitted Development, we’ll guide you through the process.
Building Control Liaison
From initial notice to final sign-off, we coordinate with your local building control officer, book inspections, handle compliance forms, and ensure all works meet UK Building Regulations.
Working Drawings & Specifications
Detailed, construction-ready plans outlining structural requirements, material specifications, dimensions, service positions and finishing details. These drawings ensure the build phase runs smoothly with no ambiguity.
Structural Calculations
Our structural engineer provides load assessments, RSJ specifications, beam calculations, and measurements required for removing load-bearing walls, creating open-plan spaces or installing steelwork.
