ý is playing a key role in supporting developer Related Argent to deliver an ambitious, £8bn regeneration of Brent Cross in north London. We are acting as strategic energy and utilities advisor and providing engineering design across the extensive new utilities infrastructure required to enable the development to take shape.
The project is driving a major transformation of the district, building a vibrant community and ensuring the area delivers more than just its popular shopping centre.
Developer Related Argent and Barnet Council formed a joint venture with the vision to create a dynamic new town and flourishing neighbourhood over the next 20 years, featuring 6,700 new homes, 3 million ft² of offices, as well as a high street, schools and parks and playing fields.
Challenge
The site, which was formerly occupied by light industrial plots, will bring together 6,700 new homes as well as 50+ new retail and food and drink outlets, 50 acres of new green space, and provide workspaces for more than 25,000 people – building a community around health and wellness with fantastic new amenities.
Creating the infrastructure needed to support this abundance of development on the site will be a key enabler to the success of the new town.
The often constrained and congested subterranean spaces for new utilities infrastructure across the site would mean the new enabling interventions would have to be carefully planned and routed for maximum efficiency.
Brent Cross Town is aspiring to be carbon neutral by 2030, so it is critical that the energy strategy prioritises the most efficient, low carbon solutions at every stage.

Solution
To support the outline planning consent, our team carried out a detailed assessment of the existing infrastructure’s capacity and limitations, before developing a strategic plan for the suite of utilities upgrades that would be required across the entire site. We delivered below-ground utilities and drainage design, creating detailed, clash-detected, 3D design models to support the coordination of the utilities and drainage, and supported stakeholder engagement with all the adopting authorities.
The utilties strategy identified that off-site reinforcement for electrical power required a grid connection from 5km away. We saved the client a significant amount of money in reinforcement costs for the power connection by using a competitive process for procurement. We also secured the additional potable water demand, working closely with Thames Water to negotiate the supply, which required reinforcements to the water network.
We developed a smart grid strategy for the development, helping the client team to build an understanding of the opportunities around in-coming technologies and renewable energy generation. We also developed the sustainability and energy strategy, which explored the inclusion of solar PV panels on many of the buildings.

To create a future-proof neighbourhood, Brent Cross Town is taking a whole-life carbon approach, looking at the total carbon emissions of its buildings and public realm over its entire life.
The neighbourhood will benefit from an advanced electric on-site energy centre, which will supply heating and cooling via buried pipes.
We acted as technical advisor to Related Argent on the district energy concession which has resulted in them getting a significant contribution from Vattenfall. We also helped the client secure £10m of ‘green heat network’ funding.
We worked with Vattenfall to develop the energy centre which will utilise energy recycling from air-conditioning and low carbon air source heat pump technology. District heat networks share heat between properties instead of each having to generate its own. It’s a more efficient and greener way to provide heat and hot water to homes and businesses, especially when the heat comes from renewable and low carbon sources.
Utilities across the site are coordinated with buildings wherever possible, so infrastructure plant does not impede on the quality of the urban realm. Our team also developed the utilities design for the highways works required to deliver the capacity for the new town.

Value
Barnet is one of London’s biggest boroughs, home to a diverse population of almost 400,000 people. The number of residents has increased by more than 27,000 in the last five years, among the fastest rates of growth in the capital. By 2030, the population is projected to increase to 450,000 people. Brent Cross Town will deliver 6,700 much needed new homes across the 180-acre site, alongside a wealth of new community facilities and workplaces. A new railway station has been developed to serve the site.
Throughout the development, we have acted as a strategic energy advisor, building a robust and efficient energy plan, while also providing insight and design input across the range of new utilities and infrastructure elements required to enable the development to take shape.
We also played a critical role in engaging with the local planning authority and Greater London Authority (GLA) to support the development through planning, as well as leading on negotiations with a range of service providers and utilities authorities.
ý developed a net zero carbon energy solution which recycles waste heat from the air conditioning in offices to give hot water for the homes. Our work on the town planning has meant that each reserved matters planning application has been successfully granted.
As well as working directly for the client, we have also been further engaged by some of the contractors on the site to support their construction design, including VolkerFitzpatrick and Galldris. Our sustainability team was engaged to develop a “Flourishing Index” assessment, to build a reliable picture of resident wellbeing and happiness.
Our infrastructure, sustainability and ecology advisors are also playing a key role in the shaping of plans to upgrade the neighbouring Clitterhouse Playing Fields. We are helping to tackle flood risk and park design consent, with a vision to transform the site into a vibrant new public park, with a diverse range of community facilities and biodiverse green spaces.
