Thomas McEwen BSc(Hons) MCIAT (Member of the Chartered Institute of Architectural Technologists) leads the practice, supported by Hannah McEwen BSc(Hons) as Office Manager. We focus on residential development including new builds, interior alterations, extensions, garden rooms and visualisations (CGIs). We handle all planning and building regulation requirements on your behalf to get you ready for construction.

Planning & Construction Drawings

Our Process

From Brief to Build

Before you start construction you need both Planning and Building Regulations approval from the council. We design and submit both on your behalf.

01

Planning

The general design of your project — scale, layout, window and door positions. Once complete, plans are submitted to the council. The application typically takes 14 weeks from submission to approval.

Building Regulations

Once planning is granted, drawings are advanced to a detailed construction set showing compliance with building regulations — used for your builder to quote and construct from. Structural engineer calculations are also arranged.

We work closely with structural engineers and can give recommendations for ecologists, topographical surveys and builders.
