Design Brief

Discreet grille design and intelligently concealed equipment. Specialist areas included the cinema, gym, spa and sauna with plunge pools, and the private wine cellar. Meticulous attention was paid to detail and integration within building fabric and bespoke joinery.


Calibre delivered a luxury indoor climate including ducted heating, cooling and ventilation in all living zones, with precision climate in specialist areas. Whisper quiet operation was achieved within bedroom areas.

Constant fresh climate control air circulating within the cinema maintains a precise environment, ideal for a pleasurable experience without distraction.

Supply and extract ventilation ensures adequate heat extraction during sauna usage to maintain a healthy environment for personal health and wellness.

A dedicated climate control system provides the optimum storage conditions for fine wines and ensures they are developing in complexity and value.

External plant was installed at roof level within an acoustic enclosure for planning, and to avoid the impact of noise generated on neighbouring properties.

One thing that I find always useful, and this is something for which I like working with your team, is your ability to listen, apply the expertise, and work with the designers to ensure a successful outcome. It is this that makes it a pleasure working with Calibre, and has meant that I have been more than happy in recommending the company to other architects and designers and even directly to clients.

On the last project that Calibre worked on with my team, we designed a inlet and extract ventilation air system hidden within the cornice, and they designed and installed a bespoke solution that worked perfectly.
