Ground floor extension, loft conversion and whole-house remodel of a detached 1930s property in Thames Ditton. The project involved a full ground floor reconfiguration and rear extension creating an open-plan kitchen, dining and living space, alongside a loft conversion adding a fourth bedroom and ensuite within a large rear dormer.
The clients wanted to transform the house top to bottom in a single project. The ground floor layout was disconnected and underused, and the loft was untouched roof space. The goal was to open up the entire back of the house into a generous kitchen, dining and living space, convert the loft into a bedroom suite, and remodel the interior throughout — reconfiguring the first floor and partially converting the garage in the process.
Ground Floor — Extension & Reconfiguration
Loft Conversion
The transformation has completely changed how the family uses their home. The open-plan ground floor, rooflights and full-width garden connection make the space feel substantially larger than its footprint, while the timber slat partition gives the living area its own identity without closing it off. From the garden, the dark metal dormer reads as a confident design addition — a clean contrast against the original red brick and clay tile roof rather than an afterthought.
This project required design and construction to be fully coordinated across every floor simultaneously. Having architecture and build under one roof made that possible.
When we needed to extend our ground floor, redesign the layout of the property, and do a hip-to-gable roof conversion we chose Rob and the team at Thames Design and Build. From the initial architect drawings, to the planning process, costings, project and supplier and specialist management, we were provided with excellent support.
Ongoing communications and guidance throughout the project ensured that for our first build we were able to reduce the stress and uncertainty that comes along with such a big life decision. The project was finished on time and to a great spec. We would highly recommend Rob and the team for any home project – big or small.
