Colmore Gate is a landmark development in the heart of Birmingham. The existing building consists of 16 floors with two basement floors over a podium and tower section constructed in the mid-1990s.
We have been working with the design team to extend and refurbish the building to provide 23 floors of office accommodation in the tower and 9 floors in the podium section, totalling approx. 315,000ft2 NIA. As part of the refurbishment, the existing VAV air handling system will be removed and replaced with an air source heat pump system with on-floor heat recovery units to provide comfort cooling, heating, and ventilation. Additionally the building will benefit from a building and energy management systems, high-efficiency LED lighting and controls.
The project ethos revolves around a core carbon principle of retaining existing structure and foundations and working within that constraint to provide new and exciting office space.
As the Sustainability Consultant on the project we are targeting BREEAM Outstanding, WELL Core Platinum, ActiveScore Platinum and RESET certified to maximise the scheme’s sustainability credentials. We are also completing a whole life carbon and circular economy assessment to see that we are maximising re-use and aiming to identify further reductions in carbon where possible.
In addition the building is subject to the Design for Performance approach with the aim to achieve a 5 Star NABERS UK rating. The building is projected to deliver an ‘A’ EPC rating.
The building’s planning application was submitted to Birmingham City Council in August 2023, and we provided all the necessary supporting documentation, including the sustainability statement and energy strategy.
We are looking forward to our continued involvement in the project, pending positive planning feedback.

The building has been transformed to provide a 133 bedroom hotel including car and cycle parking on site.

The refurbishment of 53 Great Suffolk Street in London involved the transformation of a historic warehouse into a contemporary office space. This project focused on preserving the building’s industrial character while introducing modern amenities and sustainable features.

The Adventure Park covers 1.2 acres and is created using sustainably-sourced wood from the Windsor Estate, providing an extensive playground for families to explore together.

The building is provided with natural ventilation and LTHW heating to the showroom and office areas, plus the toilets which also receive hot water from the same boiler installation.

The 47,900ft² area of The Smithson building in Farringdon was refurbished to high quality office accommodation, for which Watkins Payne supplied building services engineering, vertical transportation engineering and energy consultancy to achieve an EPC B rating. The refurbished area is spread across basement and ground floor.
