Plansplus Architectural Studio

Plansplus was founded in 2002 by Martyn Phillips to provide a fully comprehensive architectural service tailored to homeowners and property developers.

With over two decades of experience, Martyn combines creative design thinking with detailed technical expertise to deliver projects that are not only visually striking but also practical, buildable, and compliant.

From concept to completion, Plansplus supports clients through every stage — including planning applications, building regulations, construction detailing, and contract administration.

Whether you’re extending, remodelling, or building from scratch, the focus is always on clarity, quality, and making the process as smooth and transparent as possible.

Plansplus works on a wide range of residential projects - from small scale extensions and refurbishment schemes through to complex renovations and complete new builds. Our clients are typically located in Buckinghamshire, Oxfordshire and Berkshire and love our hands-on approach to design and delivery.
