The Coolest WOW!house so far: Interior Design-led AC Integration at Design Centre, Chelsea Harbour

Interior design-led air conditioning for WOW!house 2026 at Design Centre, Chelsea Harbour

For 2026, WOW!house at Design Centre, Chelsea Harbour became a rare opportunity to showcase what we are normally asked to make disappear: air conditioning designed into highly detailed interiors without becoming visible.

As a BIID-accredited industry supplier specialising in air conditioning for luxury homes, we usually work in private properties where the most interesting technical details cannot be shown publicly. WOW!house created a temporary showcase for that work, allowing interior designers, architects, journalists and homeowners to experience properly integrated cooling in rooms designed to prime residential standards.

As Official Air Conditioning Partner for WOW!house 2026, we delivered discreet air conditioning throughout the showhouse, ensuring the atmosphere inside remained cool and comfortable despite the sudden heatwave across the UK. When prompted after visiting the showhouse, visitors said that it felt much cooler than previous years and that they had not noticed where the cooling was coming from.

Air conditioning without the visible compromise

Air conditioning in luxury homes is still often imagined as a visible intervention: a box on the wall, a large grille, or a compromise accepted for the sake of comfort.  WOW!house 2026 allowed us to demonstrate the results of an altogether different approach. The airflow was designed through invisible openings in the architecture of each room, using the interior design language already envisioned by the designers, without a single wall-mounted box or unsightly grille to disrupt the overall aesthetic vision.

Room Spotlight: Black Edition for Romo Group Speakeasy Salon by Studio Duggan

Conceived by Tiffany Duggan as ‘a space layered with character, intimacy and quiet intrigue’, the Speakeasy Salon was an excellent example of intentional, aesthetic-led AC integration. Working closely with the interior designers, our consultants developed a shadow-gap detail around the circumference of the room, at the junction of the bespoke plaster frieze and the fabric-clad walls, allowing the cool air provision to sit naturally within the architectural rhythm of the room, while remaining low enough down that it did not cause movement of the tented ceiling or cause tangible draughts.

“One thing you might notice this year is that WOW!house feels wonderfully cool - something that's been hugely appreciated in this recent heatwave! What you probably won't notice is the clever air conditioning integration by Calibre. Working closely with us, they concealed the system within sleek shadow gaps running just beneath our bespoke plaster frieze, so all the focus remains on the architecture and decoration rather than the mechanics behind it. Calibre were fantastic to work with and went above and beyond to make sure everything was seamlessly integrated. It's one of those details that visitors may never consciously notice (which is very much the goal!), but it makes such a difference to the experience of the room.” - Tiffany Duggan, Founder, Studio Duggan

Room Spotlight: Misia for Casamance Group Bedroom by Henri Fitzwilliam-Lay

The art-deco primary bedroom allowed us to integrate air paths into the ‘fifth wall’. Utilising the intricate ceiling raft details, we were able to integrate air flow openings in two openings on the horizontal plane concealed by the raft’s upstand, enabling air to flow in multiple directions into the space and distribute at high level. The cooling was present in the way the room felt, but absent from the way it looked. Bedroom air conditioning does not need to mean a visible wall unit or a prominent grille.

"It’s been great to work with a company that understands it from an interior designer’s perspective: we want to feel it, but we don’t want to see it." - Henri Fitzwilliam-Lay

What WOW!house showed

For us, WOW!house was valuable because it made a normally private design process public. In prime residential projects, the most successful air conditioning installations are often the least easy to show. For one month, visitors could walk through highly finished rooms, feel the difference between a hot public building and a cooled interior, and see that no visible compromise had been introduced. It also challenged one of the most persistent assumptions about residential air conditioning in the UK: that it will inevitably be visually intrusive.

As London summers become hotter, air conditioning is becoming a serious part of the brief for prime homes. Many of these properties are visually and architecturally sensitive, whether listed, located in conservation areas, or already finished to a high standard. WOW!house allowed us to prove that comfort does not have to come at the expense of the interior. When air conditioning is planned around the architecture, acoustic requirements and available routes, the result can be completely invisible.
