Owner approach of sustainability

From the outset we strived to create a City standard office building of the highest quality that would complement our track record; that was in line with our development aspirations for the UK, and that would play its part in the transformation of Europe’s largest strategic regeneration site.

Our objectives were to develop the most effective building possible in terms of functionality and flexibility for potential tenants, and that performed to an excellent standard in terms of energy efficiency, whilst providing exceptional value for its owners, occupiers and for the surrounding area.

The greatest challenge was to achieve an extremely challenging design brief within the established budget. From early stage focused on a bespoke and technical façade as well as a magnificent atrium and two large south facing terraces.

Architectural description

6 Pancras Square has a direct relationship to the industrial character of the historic buildings in the surrounding conservation area through the use and grain of materials and vertical detailing - the fins running along the vertical piers convey depth and become a dynamic features that cast shadow and alter in appearance throughout the day.

The lower two levels are scaled to provide a strong base for the building responding efficiently and directly to the public realm. Above this, the middle and crown are formed by the expression of function and performance through a 3m grid.

ARRIVAL EXPERIENCE FOR OCCUPIERS AND VISITORS
Emerging from underground station at Pancras Square or from St Pancras station the massing of the building responds immediately to the visitor. The landscaping of Pancras Square extends beyond the building into an overhang to create a
semi-public covered space, marking the building entrance. Within, the atrium forms visual and functional connection between surrounding spaces, becoming a destination point.

Lift lobbies are accessed automatically as visitors pass through the access barrier, making the journey fluid and user friendly. Cross perspectives, across the atrium and through the façades towards key urban landmarks, allow clear way finding throughout the building.

INTERNAL SPACES
The floorplates are deep and long, allowing a unique, uninterrupted perspective of 95m. Daylight is provided by the luminous atrium.

For the upper levels, the direct access to generous south facing terraces with striking views of the cityscape offer a unique opportunity to incorporate exterior spaces that could be integrated to the interior general arrangement.

ATRIUM
The atrium leads the visitor within the building. Light is the primary material, shaping the space and emphasizing the complementarity between transparency and built form. The use of light materials magnifies light, leading the visitor’s look
towards the sky.

Product

Natural ventilation

Product category : Génie climatique, électricité / Ventilation, rafraîchissement

features were inserted in the design wherever possible and with an understanding of the site constraints and acoustic obligations. This was combined with a highly efficient mechanical ventilation system with exhaust air heat recovery.

Turbo core chiller systems

Product category : Génie climatique, électricité / Ventilation, rafraîchissement

Ultra efficient ‘turbo core’ chiller systems using high-speed axial compressors, with the compressor turbine floating on magnetic bearings to eliminate friction in the main moving part, achieve demanding energy efficiency levels. Cooling systems built into the chillers pre-cool the chilled water from the building at low external ambient temperatures without the use of refrigeration equipment.

Low carbon district heating network

Product category : Génie climatique, électricité / Chauffage, eau chaude

The building benefits from connection to the King’s Cross low carbon district heating network, including heat from a mixture of CHP, efficient gas boilers and potentially Biomass boiler systems.

Urban environment

Building is designed to integrate with the overall kings cross masterplan in terms of building use and ground level retail units. External lighting is integrated with the neighbouring buildings.

The building is within 300m of Eurostar, King’s Cross station, London Underground and London bus services.
