What we do

Our Services

From initial concept to final construction, we provide comprehensive architectural
design services tailored to your unique needs.

Architectural Design & Drawings

Our design service is built to remove uncertainty and provide complete transparency. We combine practical construction knowledge with planning-ready documentation and early budget discussions. That way, you can move forward with confidence - whether you’re aiming for a new build, house extension, loft conversion, garage conversion or a full home renovation.

Planning Submissions & Warrants

We manage planning and building warrant applications for homeowners across Ayrshire and Glasgow. From shaping the application strategy and preparing submissions to answering queries and coordinating technical information, we make approvals far less stressful. You stay informed, your budget remains realistic, and your project keeps moving forward with confidence.

Structural Engineering Reports

Structural changes can go badly wrong without proper coordination. We manage the engineering side by briefing engineers correctly, integrating calculations into your drawing pack, and ensuring compliance with Scottish Building Warrant requirements. From steels and dormers to loft upgrades and renovations, we keep the process clear and buildable.

Cost Estimation & Feasibility

A design is only useful if it fits a realistic budget. Our feasibility and cost estimation service gives homeowners an early, honest view of what is achievable before money is spent on drawings that may later need scaled back. We help you understand cost drivers, compare options, set a sensible brief, and move forward confidently.

Construction Phase Support

Most homeowners feel confident at design stage, with stress usually starting once work begins on site. Our Construction Phase Support service provides a dedicated contact to help keep the build aligned with drawings, scope and programme. We support meetings, coordinate information, track progress, and manage change control to protect budget, reduce delays & uncertainty..

Garage Conversion

We used CWJ Design for our loft conversion and were very pleased with the service. The design was well considered, the drawings were produced promptly, and everything was explained clearly. The process felt organised throughout and made moving onto the construction phase much easier.
