Developer Landsec has revised plans worth £400m to build two landmark office buildings in Manchester city centre.

The office buildings making up the first phase of the city centre £1.5bn Mayfield regeneration scheme will become net zero exemplars under the revised plans.

New plans for the Mayfield neighbourhood highlight the shift towards premium, sustainable office space in the best locations, as businesses adapt their workspace to attract talent and meet the changing needs of staff.

Phase 1 of Mayfield features 320,000 sq ft of office space across two new buildings – The Poulton and The Republic.

Landsec has reworked plans to achieve targets of 600kg CO2 per m2 driven by lower embodied carbon emissions using innovative building techniques and new, lower impact materials.

With the proposed buildings in close to the city’s first new public park in over 100 years, the new plans are set to help employees achieve the ideal work life balance.

As part of the building back greener plan an existing muti storey car park will be remodelled into a multi-use building with 500 sq m of PV panels, while featuring one of the city’s biggest, single-site cycle parking for over 400 bicycles.

The Mayfield Partnership is a collaboration between Landsec U+I – the regeneration arm of Landsec – Manchester City Council, Transport for Greater Manchester and LCR.

Deborah Freeman-Watt, head of Regional Mixed-Use Development, Landsec said: “This is an exciting milestone for us, one that accelerates the green development of one of the UK’s leading business communities.

“Mayfield Park has already contributed a beautiful new public amenity in the heart of Manchester. It is only right that the buildings among it are just as focused on wellbeing and sustainability as the communities within.

“With all three of the buildings in this first phase targeting a 5.5-star NABERS ratings they will be fit to serve communities efficiently and sustainably, delivering for the sustainability goals of the city.”
