About Us

Atrium LDN was founded in 2012 by James Coleman and Michael Walsh, both experienced construction professionals from very different backgrounds. James is of a professional background, being a RICS qualified Quantity Surveyor and Michael having worked his way up through the trades to at peak employing over 50 operatives to deliver subcontract works.

They realised the component parts of their talents combined would make a company with more knowledge and ability such that the service they could provide would be greater for the client, the user and themselves.

It was on this basis that Atrium developed over the coming years working in most lines of construction, with the primary focus being on commercial fit out. In the last few years the variety of works has broadened to meet client and market requirement to smaller new build and heavy refurbishment projects. With over 30 years combined experience working for main contractors, subcontractors, developers and consultants, Atrium are now able to deliver larger and more diverse projects.

We work on a collaborative, non-adversarial basis taking consideration of the fact that the construction industry in the most part produces a bespoke never built before product near enough every project (whether this should be the case is a different conversation), which requires many different professions, skill sets, people to realise the end product. We believe that construction is the largest team game in the world, as no one party can do this by themselves. So as they say “The whole is greater than the sum of the parts”.

Atrium can proudly state that they have never been involved in an adjudication, mediation or dispute.
