ASDA (part of the Wal-Mart Stores Inc.) has long strived to become 100% energy efficient, hence they were the first in UK to build a sustainable timber -framed store, which is 20% more energy efficient than their traditional stores, as well as lowers the store’s carbon footprint by as much as 50 per cent. 

We developed the designs for the prototype, which were to become a blueprint for all ASDA’s future eco-stores. The design was centered around the main principle -a large format timber frame utilising Glulan.  The PEFC- sourced timber frame eradicates the need for 500 tonnes of steel, thereby saving 450 tonnes of carbon emissions, while also allowing “greater design flexibility” creating a low maintenance and highly insulated building. 

Bricks from the old mill originally on the site were used to further lower material costs, use of natural light ingress was promoted and low level motorised louvres helped to aid cross-ventilation- all designed to make the store optimally energy efficient. The south facing roof captures light and heat from the sun and is made from 85% recyclable aluminium which has the added benefit of being
longer lasting than PVC.

The first store opened in Shaw, Oldham in 2007, followed by the £27 million, 40,000 sq ft store in Bootle,  Merseyside in 2008, which on top of the expected bio-mass boiler and low-energy freezers  (Mistral), also has higher levels of daylight than it’s traditional branches. The eco stores cost about £2 million more than a traditional ASDA store to build at the time, hence only a handful were constructed, but Atom designed elements of the eco-store have become the blueprints of all new ASDA stores across the UK.




” Through the addition of a range of innovative energy efficiency measures to our plans, we expect that the completed Shaw store will now be 20% more energy efficient than when we first planned to build it. Through the construction of this store our aim is to create a template that will become the model and blueprint for all our future store developments. At ASDA we are fully committed to the targets we have set ourselves for improving the energy efficiency performance of our buildings. The development of the new store in Shaw is just the first step and there will be many new environmental initiatives introduced over the coming months and years that will help us achieve our goals “.

Nairn’s Oatcakes- Edinburgh

A previous brown-field site was developed into a brand new BRC Compliant gluten-free production facility for Nairn’s gluten-free biscuits and oatcakes, obtaining a top rating during their first BRC audit in 2017. The spend matched the budget and the project was delivered on time helping to meet extremely tight deadlines.

Vauxhall Underground Station- London

The Vauxhall Underground Station modernisation is part of Transport for London’s ongoing investment into London’s public transport network to support economic growth and employment opportunities.

The £36m project entailed reconfiguration of the station’s ticket hall to accommodate extra ticket gates and wide-aisle gates, as well as the refurbishment of the stations’ subways, ticket hall and stairs. The main part of the project was to make the access to the station step-free, enabling the station to handle 40% more passengers by installing a new shaft and lift between the ticket hall and platforms. A particular challenge was posed by the station remaining fully operational while the construction work took place between 2014 and 2016.

Winton Primary School Sports Hall- London

The London Borough of Islington had a requirement for a new sports hall to be used out-of-hours by the local community and it was to be built on the roof of and existing school- Winton Primary School.

To minimise disruption to this ‘live’ site, a modular approach was adopted. All components of the build were pre-fabricated, starting from the structural steel wall and roof panels and ending with the beautiful western red cedar clad external facade.
