Notting Hill III

The first-floor dining and lounge area is supplied by a horizontal unit in the adjoining powder room ceiling, through a minimal wall-length plaster-in diffuser. A fine-line plaster-in bar grille inside the bar alcove ceiling provides a path for return air, positioned outside of the main ceiling line to be beyond line of sight.

On the second floor, an identical grille supplies the master bedroom, with return air through a series of minimalist joinery slots. The requirement for comfort cooling to be almost inaudible in this room led to attenuation of the unit for almost completely silent system operation. Discreet plaster-in diffusers and joinery slots provide supply and return air paths to the three children’s bedrooms on the third floor, while climate control to the fourth-floor guest bedroom and wellness room takes place through a single linear diffuser in each ceiling, aligned with the bespoke coving detail.

A unique combination of centralised and decentralised ventilation from a single MVHR unit provides fresh air to the basement and bathrooms through a series of invisible shadow gap details.

Collaboration with the home automation contractor resulted in a design fully integrated with the Lutron system and controlled by a series of sleek black wall controllers and infrared remotes.

Two external condenser units housed in an acoustic enclosure under the lightwell stairs, flush with the wall, provides the supply air to the property in line with local planning requirements, invisible and inaudible from the road.
