Pegasus House

Iconic art deco office building rejuvenated for a new generation of aviation engineers

The Project

Standing immediately beside Barnwell House, iconic Aerospace Building Pegasus House has also officially opened following restoration and renovation works. Originally the headquarters of the Bristol Aerospace Company, Pegasus House is a Grade II listed art-deco building built in 1936 which is now at the heart of the new Airbus Aerospace Park. Several heritage features have been retained including a historic four storey stained glass window that chronologically illustrates the evolution of the Bristol Aeroplane Company’s planes, referencing Greek mythology & folklore.


The Approach

The design brief required that Pegasus House not only to be restored to its former glory, but also become viable in terms of business requirements as befits the modern aerospace industry. Oculus provided expert advice on the application of BS 9999:2008 “Code of practice for fire safety in the design, management and use of buildings” in order to meet the clients aspirations and ensure this was achieved in this historically significant building.


CASE STUDY
National Museum of the Royal Navy

Storehouse 10 at the historic naval dockyard in Portsmouth was constructed in the mid-eighteenth century, during an upsurge in naval building prompted by events such as the Seven Years War. It was originally used to store everyday supplies for working ships plus some naval items.

During the Second World War, Storehouse 10 was hit by an incendiary bomb, which destroyed the clock tower and most of the roof and upper floors. More extensive damage was prevented due to a strenuous firefighting effort to save the radar sets within, which were to be some of the first installed in Royal Navy ships.

Restoration of Storehouse 10 was gradual and was eventually completed in 1992. It has now been converted to form part of the National Museum for the Royal Navy complex.

CASE STUDY
The Gainsborough Bath Spa

The Gainsborough building situated in the heart of Bath was formerly part of the City of Bath College. A Grade II listed building from the Georgian period designed by John Pinch the Elder. The conversion to a 5* luxury hotel presented many challenges. The new multi-storey Lower Borough Walls wing reflects the host building architecturally. In the heart of the hotel lies Spa Village Bath, which is quite unique insofar as it has access to the natural thermal mineral-rich waters, making it the only natural thermal spa inside a hotel in the UK.

The main stair protection was particularly challenging as enclosing it was not an option from a conservation perspective. A solution of discreetly placed fire curtains operating on the fire alarm system to provide protection was developed. There are also isolated areas with sprinkler protection to provide an alternative to passive fire protection.

CASE STUDY
Airbus - AWIC

The £40m facility will enable Airbus to perform structural tests on aircraft materials, components and large assemblies, including complete wings. The strong floor will support a 220-tonne, 10m-high steel wall where structural tests specimens will be attached to allow testing to take place.

The pour itself lasted a continuous 23-hour period, one hour under the scheduled 24. It required a lorry load of specially prepared concrete to arrive every six minutes to provide a constant supply to the pour and avoid any inconsistencies in the concrete.

A total of 1,440 cubic metres was poured into the floor, which measures 40m by 18m, to a total depth of two metres. The steel reinforcement amounted to a total of approximately 280 tonnes of rebar, estimated to be around 54 km laid end-to-end.

The AWIC facility is supported by the Aerospace Technology Institute (ATI), Department for Business, Energy and Industrial Strategy (BEIS) and Innovate UK.
