Converting the Grade II listed former Regent Palace Hotel was a key element in The Crown Estate’s redevelopment of southern Regent Street.
Located in a prominent West End site, the construction project certainly had its challenges. These included preserving its art deco features through careful cataloguing and specialist restoration.
Thanks to robust logistics, close collaboration and careful management of trades and interfaces, we made sure the project ran smoothly and completed under budget and ahead of schedule.
Offering state-of-the-art offices, apartments, exquisitely finished retail and restaurant spaces, and a dedicated energy centre, Quadrant 3 is a model for the regeneration of historic buildings.
Thanks to meticulous project management, planning and close collaboration, we significantly reduced programme and costs.
More than half of the façades were retained, along with 1,500 tonnes of steel which was incorporated into the new build.
Raising more than £60,000 for charity, we also donated salvaged construction materials to local charities.
Working closely with our project partners, we used BIM and 3D modelling of services and structures to:
- De-risk the building’s design, construction and operation and ensure a fully integrated handover.
- Increase productivity, streamline construction and improve safety.
- Aid prefabrication.
- Effectively co-ordinate work onsite.
Innovating to save time & money
With expert input from project team members and our in-house design group, we developed an innovative temporary works solution, which allowed us to deepen the basement while demolition proceeded above. This saved costs and reduced programme by 14 weeks.
We used the best in modern and traditional construction techniques to conserve the building’s Art Deco features. The interiors were carefully catalogued before being dismantled and removed for later reinstatement. Timber and plaster features were also carefully recorded for future reference.
Rated BREEAM Excellent and Level 3 Code for Sustainable Homes, sustainability was paramount in Quadrant 3’s design and construction.
