About the project

ZEBRA@Lion House is a flagship ultra-low emissions office, designed to achieve exemplary standards of sustainability and environmental performance.

Procured through an OJEU compliant framework, the building replaces a dilapidated office, which contained asbestos. The new 1,800 square metre two-storey building provides a flexible and sustainable working environment.

The client was committed to making Lion House carbon neutral. It is the first office building and the first government-owned building to achieve an A+ EPC certificate and has a BREEAM ‘excellent’ score.

Low or zero carbon strategies include a biomass boiler, predicted to meet 85 per cent of annual heating requirements; solar collection, predicted to deliver 50 per cent of the annual hot water demand; three 15kW grid connected wind turbines; photo voltaic panels incorporated within the solar shading; and rainwater harvesting. Performance data is still being gathered, but so far all these technologies are providing better results than predicted.
