Portland House
The development at Portland House will comprise circa 300,000ft² of primary office led accommodation together with retail and amenity space.
20 Air Street sits in the heart of London’s West End and was completed in 2011. The 2nd, 4th and 5th floor leases had expired and The Crown Estate commissioned the design team of Watkins Payne, Cogent and Orms to complete a refurbishment and reinstatement of these floors to return them to Cat A for re-letting. The project also involved the refurbishment of the reception space and improvement of the cycle store entrance and wayfinding at basement level.
The brief was clear in that replacement of equipment was only to take place if necessary and so all fan coil units, primary ductwork and pipework across the floors was re-used wherever possible and recommissioned to meet the original Cat A layouts.
The MEP services were subject to a validation exercise which showed that the control valves serving the fan coil units needed replacing and so these were replaced across all of the floors and in the reception. In addition the lighting in the Cat A spaces was replaced with new. In order to minimise wastage the 2nd and 5th floors had only a portion of the floor completed with a ceiling layout to show how a tenant could fit out the space. The rest of the floor was left without a ceiling and temporary lighting to allow the space to be let but all equipment in these areas was recommissioned.
The building is subject to BREEAM RFO 2014 and is on track to achieve a ‘Very Good’ rating.

Watkins Payne carried out the Independent Design Review role for Red Lion Court, a mixed use commercial office development, located in central London.
The completed site now comprises four detached industrial warehouse units ranging from 14,000sq ft to 36,000sq ft, all with naturally ventilated and heated offices. The two larger units each have an 8 person MRL passenger lift, while the smaller units have been provided with platform lifts. The warehouse area was designed as a shell for future fit-out with capped off utility services.
