Sustainability
We approached sustainability as a core part of the design, guided by RIBA 2030 outcomes. Careful consideration of materials and building performance allowed us to balance comfort, efficiency, and environmental impact.
Through energy and thermal modelling, we optimised fabric performance, natural ventilation, and glazing to deliver a passive, low-carbon solution within a constrained site and budget.
Looking ahead, the building will connect to a low-carbon district heat network, further reducing CO₂ emissions. This approach supports NHS Lothian’s journey to net zero carbon by 2045, while demonstrating how thoughtful design can achieve measurable, long-term sustainable outcomes.

We understand how deeply architecture can impact health and wellbeing, and our healthcare team is proud to have created a building that is having a strong, positive impact on the health of present and future patients. We’re delighted to work with NHS Lothian to improve their healthcare estate with the new Renal Unit, and most recently their new Linac treatment facility.

We’re seeing the positive impact this fantastic facility is having on patients and staff. The clinical area is as light and airy as possible, but also more peaceful, giving patients a much better experience. The unit will be a great benefit for patients for years to come.

A design that prioritises patient experience
Patients in the renal unit can spend several hours a day in treatment, so their comfort was our first priority.
We arranged the upper level with main treatment rooms located to the south, offering scenic views towards Edinburgh’s West End and Edinburgh Castle. The staff base is located at the heart of these treatment areas to maximise patient observation. A clerestory rooflight directly above the base brings further natural light deep into the plan, creating a vibrant space for staff.
