Background

What is a data centre?

A data centre is almost like a giant library, but instead of storing books, it stores and manages large amounts of digital information and IT infrastructure.

It contains powerful computers and equipment that keep websites, apps, and online services running.

Whenever you use your phone to look up something, stream a video, or send an email, you’re probably connecting to a data centre somewhere in the world. As a result, many of the activities we take for granted in our day to day lives would not be possible without the provision of data centres in our IT infrastructure.

Demand for data centres is growing rapidly, encouraged by the growth of the AI sector which the UK Government has prioritised as a key growth sector.

Data centres are critical for the UK economy, contributing an estimated £4.7bn in Gross Value Added to the UK economy annually. This means that their presence can add substantial value to the economy of the surrounding area.

The site

The Heathrow Estate is a multi-let industrial site in Cranford, Hounslow. It currently only provides short to medium term opportunities via leasing units to tenants.

Cranford Primary School is located to the north, bordering the site’s boundary. There are also residential properties to the north in Chaucer Avenue separated by an emergency access to the school.

Existing site

Proposed site

It is currently designated as a Locally Significant Industrial Site (LSIS), and failing to maximise its potential. Therefore, the site would benefit greatly by being redeveloped into a data centre.

Vision

Our vision

The Heathrow Estate is failing to maximise its potential. Redevelopment as a data centre could lead to a wide range of local benefits, including significant CIL payments, higher Business Rates income, and the creation of skilled jobs in the local area.

With demand for data centres increasing nationally, Hounslow will benefit from the delivery of new data centre capacity at the strategic location of the Heathrow Estate.

Local benefits include

Significant reduction of traffic movements and noise

The site has good transport links, being in walking distance from Hatton Cross and Hounslow West tube stations

A number of high skilled jobs, both in construction and operation

Significant increase in biodiversity net gain

Efficient use of previously developed land

An increase in green space on the site, from 5% to 20%

The building will achieve a BREEAM Excellent rating

Possibility of a new education facility regarding data centres and new technology

Improvements to cycle routes

EV charging for all parking spaces for employees

New SME units on site to support local businesses and boost local jobs

Scheme design

We are proposing using simple modern contemporary high-quality materials suited to the building’s use and content.

Hover to see existing site

The main data centre building will use a combination of long panels in a variety of colours, designed in a varying pattern from elevation to elevation to breakdown the overall impact.

Proposed layout

The main office building is the most eye-catching part of the development and is located right at the entrance. To make the building look less imposing, the top floor is set back, which creates a spacious balcony for people working there to use.

Proposed layout

The sides of the office building have lots of large windows. Special sunshades, both vertical and horizontal, have been added. These not only make the building look more attractive, but also help keep it cooler by blocking out some of the sun’s heat.

Proposed layout

Landscaping

The site around the data centre presents the opportunity to introduce landscaping that will help to create a green environment with greater biodiversity.

The current buildings cover 54% of the site. Our proposals reduce this to 42%, meaning more greenery and open spaces for local residents.

The design can support the operational needs of the data centre whilst also offering environmental and social benefits to the wider community. This will be carried out by integrating planting, accessible walking and cycling paths to nearby open spaces, and areas for informal recreation.
