The Finer Details:

This unique building has won many accolades for its design including the RIBA London Regional Award 2015, The RIBA London Sustainability Award 2015, and most recently, the Prime Minister’s Better Public Building Award. Furthermore it has achieved the BREEAM level of ‘Outstanding’.

It was built as the new headquarters for Camden Council and is clad at the lower levels with Techrete precast concrete panels. There were a lot of constraints encountered on site and the ground to 3rd floor cladding had to be installed in advance of the super structure. Due to the site logistics and proposed crane sizes and positons, normal installation hours could not be accommodated on site as these would have blocked deliveries and affected progress on site. There was also site off -loading restrictions.

To avoid these issues, Techrete panels were installed between 7pm and 7am using the site tower cranes. The line and level works were carried out during the day. Another challenge faced was the installation of the circular columns. This proved interesting as they were underslung units and there was reduced headroom available.

As with other projects in the Kings Cross area, there were network rail restrictions which required the downgrading of all craneage by 25%. This problem was alleviated by using mobile cranes where appropriate, although there was some back propping required to the slab during this operation.

A reconstituted stone mix was chosen in an acid etched finish which gives the building a regal finish, allowing it to blend effortlessly with the prestige of the neighbouring buildings and surroundings.
