Project overview
This project involved transforming a former chapel into a distinctive residential home through a full structural redesign delivered in collaboration with Lawray Architects. The works centred on creating a modern, split‑level living environment by introducing a new mezzanine structure and undertaking opening‑up works to enhance natural light throughout the interior. The result is a contemporary dwelling that retains the character of the original building while supporting a new way of living.
The engineering challenge
The scheme presented several challenges, including:
- Integrating new structural elements into an existing chapel without compromising its architectural character.
- Ensuring the mezzanine structure could be safely supported within the original building fabric.
- Introducing larger openings to increase natural light while maintaining structural stability.
- Working within the constraints of an older building with unknown or variable existing conditions.
The engineering solution
JPS was responsible for:
- Planning a structural design that respected the chapel’s historic form while enabling modern living requirements.
- Close collaboration with Lawray Architects ensured structural interventions aligned seamlessly with the architectural vision.
- A carefully engineered mezzanine structure designed to create split‑level living space without overloading existing walls.
- Opening‑up works that were strategically planned to maximise daylight while reinforcing affected areas to maintain overall stability
The outcome
- The former chapel was successfully converted into a unique residential dwelling with enhanced spatial quality.
- The new mezzanine introduced dynamic, modern living levels that complement the building’s original character.
- Increased natural light transformed the interior environment, making the space brighter and more welcoming.
- The structural solutions ensured long‑term stability while enabling a contemporary design that met the client’s aspirations.
