Putney Project

Case Studies

Explore real Studio Casa projects and see how we transform homes with smart design, compliant drawings and build-ready solutions. Each case study outlines the project scope, floor area added, design package cost and estimated construction budget, giving you a clear understanding of what’s achievable. You’ll also see the actual deliverables we produce, including detailed 3D visualisations, existing and proposed floor plans, Building Regulations drawings, and structural design calculations, so you know exactly what to expect when working with us.

This project combines a new side extension with the existing rear extension, creating a bright, open-plan kitchen extension with large glazed openings that maximise natural light.

Although a similar proposal could often be completed under Permitted Development, this property is a flat, which means Planning Permission is required.

The side extension was carefully designed to minimise its impact on the upstairs neighbour by keeping the new roof as low as possible while still achieving the client’s vision. Before submitting the planning application, we also supported the client in obtaining the necessary consent from the shared freeholder, helping ensure the project could move forward smoothly.

The result is a spacious, light-filled kitchen extension that creates a seamless connection between the home and the garden, while making the most of the available footprint.
