Types of House Extension We Build
Every extension is unique. We design and build across all the main extension types — advising on the best approach for your plot, budget, and planning constraints.
Rear Extensions
The most popular choice for Nuneaton homes. A rear extension adds a large, open-plan kitchen-diner, family room, or home office. Typically permitted development for single-storey builds under 4 Metres.
Side Extensions
Maximise your plot by building into the gap beside your home. Ideal for semis with side access. Can add a utility room, garage, or form part of a larger wraparound design.
Wraparound Extensions
Combine rear and side to create a sweeping addition that transforms your entire ground floor. More space, better proportions, and the most dramatic visual impact of any extension type.
Recent Projects — Built by Parker Grears
Every project is different. Every one is built with the same level of care, precision and quality. Here’s a selection of our recent extension work across Warwickshire.
Double Storey Extensions
When you need maximum space added across two floors — a downstairs room plus an upstairs bedroom or en-suite — a double-storey extension delivers the best value per square metre of any type of build.
They always require full planning permission, and design matters: our architects create extensions that look designed-in rather than bolted-on, matching materials, rooflines and window proportions to your original property.
Typical timeline: 20–28 weeks from planning submission to handover.
