Spectacular baroque Octagon Room refreshed and augmented by new and refurbished wings
The complete refurbishment of the Orleans House Gallery in Twickenham, originally built in 1710 by John James – in particular its spectacular Grade 1-listed Octagon Room – has been revealed by Donald Insall Associates, together with a new north wing and reburbished west wing by Kaner Olette Architects.
The extensive work over a 17-month period has been funded by the Heritage Lottery Fund’s ‘Transforming Orleans House’ project.

Kaner Olette Architects have completed a new north wing and refurbished the west wing which also includes a study gallery with a permanent exhibition designed by ZMMA. The design of the north wing aims to avoid ‘assertive aesthetic contrast’ with its 18th century neighbour by replicating the architecture of adjacent service buildings. The new wing features an accessible entrance, a new reception, shop and training facilities.
Donald Insall Associates’ restoration of the Grade I-listed Octagon Room is the focal point within the gallery complex. It involved the restoration of lost elements such as the main chandelier and improved circulation through two original entrances. The Octagon Room hosts community, education and visitor activities.

From the outset the architectural approach was developed as a close collaboration between Kaner Olette Architects and Donald Insall Associates. Both practices have been working on a variety of projects for many years at the site but this was the first where we worked together. Placing the splendour of the James Gibbs’ Grade 1 listed Octagon back at the centre of the site both visually and physically was one of the key challenges of the project. Taking the bold opportunities to open up new vistas and creating a positive three dimensional relationship with the reception and main gallery spaces brings a whole new rich balance to the building. Juxtaposing the freshly exposed raw materials and contemporary elements against the finely restored baroque interior was a careful balancing act of what to leave and what to remove. We both love the dramatic spatial progression achieved, how daylight now floods into the interior but especially enjoy the way the full 300 years of history is now there to see.
