Sustainable Transport Interchange and Hub
Harlow, Essex
The major regeneration of Harlow bus station and Terminus Street area to transform a run-down part of the town into a vibrant & welcoming gateway.
Twickenham, Greater London
Solum Regeneration
This transformational re-development of Twickenham train station delivered a brand-new station building and infrastructure improvements, along with 121 new homes and a public plaza housing shops and a café above a busy operational rail line.
The scheme by Solum Regeneration – a joint venture between Kier Property and Network Rail – delivers meaningful improvements through the development of under-used railway land. The regeneration project not only delivers a major station upgrade but also delivers much-needed housing and facilities for the community.
The mix of one-, two- and three-bedroom homes are split across three blocks, ranging from three to six storeys, built above and beside the new station. A 1,400 square metre raft above the rail tracks accommodates the public square and new concourse/ticket office.

Station improvements include a landmark station building, a larger ticket office, improved platform access, new lifts, stairs, toilets and improved car parking.
The new station’s step-free access provides for all station users, whilst a new riverside pedestrian and cycle walkway – including children's playspace - connects the station site to Moormead Park via Network Rail land that was previously inaccessible to the public.
The development achieved Code for Sustainable Homes Level of 4, with the commercial elements of the development being classified as BREEAM Excellent. The project was highly commended in the ‘Development of the Year’ category of the Property Week RESI Awards 2023.
McBains’ MEPH design and involvement comprised a communal / district heat network, mechanical ventilation with heat recovery (MVHR), residential sprinkler system, lifts, boosted cold water, electricity capacity upgrades, overheating analysis, utilities negotiations and extensive liaison with planning regarding conditions such as NOx emissions.
Our engineers were responsible for providing performance specifications and drawings for the contractor to develop, before proceeding to monitor the detailed design and undertake regular site inspections to ensure the installation adhered to the contract documents. This involved regular and in-depth liaison with the contractor and close collaboration with the teams on the ground.
Energy efficiency measures include improvements in the thermal performance of the building fabric to achieve U-values of 20 - 48% better than building regulations, and air permeability of 50%. In addition, measures to improve detailing to reduce thermal bridging, energy efficient lighting and whole house ventilation including heat recovery were also introduced. These measures led to over a 40% reduction in CO2 emissions compared to the requirement of Building Regulations Part L.
A site-wide heat distribution network and gas-fired Combined Heat and Power (CHP) allows connection with a future district heating network if such a scheme develops within the Twickenham area. Roof top photo voltaic cells are installed, along with water saving devices including low flush toilets, aerated shower heads and spray taps. The scheme provides electric car charging points, along with 250 covered cycle spaces for commuters and 208 covered cycle spaces for residents.
The biodiversity within the area was enhanced by adding green roofs to all buildings and ensuring minimal intervention to the existing tree and plant life within the area, creating a significant extension to the green public space.
