Overview

What the client wanted

Simon and Nicola purchased a home that required significant renovation, but with a young family and busy schedules, they needed the transformation completed quickly before moving in.

They chose a full design and build service to manage every aspect of the project while still being involved in key decisions. The result is a thoughtfully extended and fully renovated home, completed in just five months, that perfectly supports their lifestyle.

How we delivered it

The project required a seamless balance between speed, quality, and collaboration. Simon and Nicola needed a team who could take full control while keeping them informed and involved at key stages. A design and build approach ensured efficient delivery without compromising on personal input.

The design process began with understanding how the family would live in the space. Internal layouts were reconfigured, including adjustments to doorways and the addition of French windows opening onto a new patio, transforming how the home connects to the garden and how spaces are used day to day.

Interior design played a central role. From statement features like the hallway lighting to bespoke details such as window seating, every element was carefully considered. The introduction of solid oak flooring, a bespoke kitchen, and custom wardrobes created a cohesive, high-quality finish throughout the home.

Quality craftsmanship was key, with skilled joinery and high-standard installation evident across all aspects of the build. At the same time, modern living requirements were fully integrated, including AV systems, data cabling, surround sound, and bespoke lighting, all coordinated under one roof to remove the stress of dealing with multiple suppliers.

“We felt the team got the balance right, they respected the fact that we were really busy and got on with the work but they also involved us whenever necessary, and kept us updated on progress.”
