Winner: Lendlease Construction Europe – South Gardens, Elephant Park
The award for the Sustainable Project of the Year always attracts strong competition and this year has been no different.
The 2018 shortlist featured entries ranging from major rail stations to smart housing developments.
However, Lendlease’s ambitious residential project at Elephant Park in London boasted a wide array of sustainability credentials that saw it rise above the competition to claim victory.
The 360-home scheme has a value of £110m and is the first phase of a wider 2,718-home £2.3bn development due to complete in 2025.
At the heart of the South Gardens project are 15 three and four-bedroom townhouses, built to the Passivhaus standards and featuring cross-laminated timber (CLT) as their main structural material.
Passivhaus standards require extremely high levels of airtightness and the use of whole-house mechanical ventilation, which results in heating and cooling-related savings of up to 90 per cent. Lendlease reports that these are the only homes built to this standard in central London.
Green roofs were installed on all the apartment blocks in the scheme that could accommodate them, which has the dual benefit of improving buildings’ environmental impact as well as their contribution to urban heat islands.
“The scale and the ambition of the project and the willingness to experiment with Passivhaus were very impressive”
Wastewater is collected, treated and recycled to flush toilets in the buildings, while the contractor also managed to divert 98 per cent of construction waste from landfill.
The final development will feature 1,000 new trees and create 4.5 ha of new public spaces, which is equivalent to six football pitches.
The company’s commitment to applying the lessons from this project to future developments extended to its suppliers, which were also able to upskill their teams as a result of working on the scheme.
All of these measures saw Elephant Park become one of only 18 projects globally to be signed up to the C40 Climate Positive Development Programme, which commits it to hitting net-negative operational carbon emissions by 2025.
“We were impressed with the scale and the ambition of the project, the willingness to experiment with Passivhaus, and the commitment to include this in future developments,” the judges said.
“The level of community engagement and the fact that the project will leave a legacy of a new urban park for London were also impressive.”
The judging panel also praised Lendlease’s transformation of a strategically important site in London – something “others have tried and been unable to make work”.
Highly commended: Multiplex Construction Europe – White Collar Factory
Multiplex’s multi-use development, White Collar Factory, made a strong impression on the judges due to the firm’s desire to challenge what an office building should be and how it should be used.
The project consists of a low-rise building and a 16-storey tower, which includes office space, nine residential apartments and restaurants. It features a green roof and 150 m rooftop running track, as well as bat boxes, bird boxes and log piles.
As the climate changes, the building’s air conditioning and solar shading adapt to maintain the temperature and use as little energy as possible.
The £103m development achieved both LEED Platinum and BREEAM Outstanding ratings, with Multiplex reducing embodied carbon during construction by 30 per cent compared with initial estimates.
