Great Ormond Street Hospital, London



A state of the art development of wards, operating theatres, and outpatient facilities. This new building uses resources efficiently, reducing negative impacts on human health and the environment.

Sustainable design

Passive design techniques combined with improved ventilation and the thoughtful selection of materials helped the building to achieve an NHS Environmental Assessment Tool (NEAT) rating of Excellent. GOSH were joint winners of the award for ‘Best Environmental Strategy’ in the Estates and Facilities Management Class of the Better Building Healthcare Awards in 2008.

Tackling climate change

Integrated bio-climatic design principles were incorporated in the building’s configuration  (ie. orientation, form and façade design). The glazed areas on the façades optimise natural daylight into the interior spaces, thereby reducing the need for artificial lighting. As a result less energy is consumed, reducing operational costs

The building combines natural and mechanical ventilation, alternating depending on the different times of the day or season. This maximises comfort, while avoiding the significant energy use and operating costs of year round air conditioning. The ventilation is optimised by an automated Building Management System (BMS) that enables users to fine-tune the control of their own individual internal environment.

Resource efficiency

We managed to achieve a waste production figure of 129 m3/£1m which was 28% below the target set for the project.

Using prefabrication, including the electrical switch room, high level service runs and ‘Ruukki’ composite cladding panels, contributed to us surpassing project targets. Prefabrication also reduced deliveries to site and construction time.

We used excess concrete to create temporary paths, access ramps and piling matts and then re-processed any leftover material for use elsewhere.

Of the waste that was produced, 97% was diverted away from landfill.

Sourcing responsibly

Ensuring the materials we use are healthy and perform to a high standard is important. We selected interior finishes which had low Volatile Organic Compounds (VOC) levels, creating a healthy environment for patients and staff.

The external cladding has BRE Green guide A rating and the curtain walling utilises recycled aluminium. We also selected to use Fermacell high performance wall board which is robust and made from 100% recycled material as a lower carbon alternative to plasterboard.

Embodied carbon was reduced further by specifying concrete with 40% cement substitute. Of the timber used, 99% came with full chain of custody, and all of the timber was from verified legal and sustainable sources.

Community Engagement

Throughout the project we continually communicated the progress of the building to the local residents through detailed newsletters.

We developed a relationship with the Construction and Built Environment department at neighbouring University College London (UCL). We provided four weeks of work experience and two site visits for students, as well as supporting final year dissertations.

Great Ormond Street Hospital has a ‘Raising the Roof’ charity campaign, which we, along with four of our subcontractors, committed £10,000 a year to, for three years, fundraising a commendable £150,000 in total.

Our team also supported local charity Coram Fields while on site, by raising over £1,000, providing trade assistance and constructing an insect hotel.

Health and wellbeing

Our approach to the safety of our workforce was commended as we ensured that labourers without English as their first language were buddied with a translator. The Health and Safety Executive (HSE) Inspectors were so impressed with our approach that we were asked to produce a DVD to show how we induct people without fluent English. The induction film was produced in ten languages and identifies health and safety risks.

The site team also impressed CCS monitors and won a Gold award in 2010.
