T2-T3 King's Cross designed by Bennetts Associates and developed by Argent, is a Grade A office building in King’s Cross. Cundall was employed to provide engineering services and BREEAM support up to RIBA stage 3 with the building due for completion in early 2019.

The building will house a range of amenities including a medical centre, cycle storage, café space and mezzanine level. The spacious reception area will focus around two central atria with the 11 floors above offering 230,500 sq ft of office space.

It has achieved BREEAM 2014 ‘Outstanding’ and will be linked to the site-wide district heating network. The building has been designed to be the lowest energy building on the new King's Cross site and full energy prediction modelling has been carried out including evaporative cooling, displacement ventilation, night cooling to exposed concrete soffits and a cutting edge 1.5MWe fuel cell which will provide nearly 100% of the developments heating and hot water requirements as well as 80% of the electricity demand. It’s also been designed to maximise the environmental benefits of its location, with orientation, thermal modelling and the use of thermal mass for cooling, all contributing to the energy efficiency of the building. T2-T3 also benefits from district cooling with high floor to ceiling heights, and full-height glazing providing the space with maximum daylighting.

The scheme has been designed ‘upside down’ with all plant and mechanical services being allocated to the back of house areas on the ground and first floors. This design frees up space at the top of the building, allowing for communal roof garden terraces.

The building will use locally scoured sustainable materials. Life cycle carbon analysis of the whole building has been carried out with the building’s carbon footprint predicted to be significantly beyond any other building of this type.

In order to achieve the BREEAM 2014 ‘Outstanding’ rating, sustainability was embodied into all elements of the design from grey water harvesting to the ecological footprint of the site. The final design stage score of 87% is one of the highest in the world and testament to the great efforts of the entire design team.

Vertical transportation for passengers will be provided by a five and a seven lift group of lifts operating with a destination control system. Additional lifts are provided for goods movement and plant replacement, coupled with providing the firefighting lift solution for the buildings.
