About Us

Room Below is part of the GeMech Foundation's Group of Companies who are specialist Civil Engineering Contractors engaged in foundation design, piling, ground improvement, retrofit, deep and new build basements for domestic and commercial markets, renovation of period property and new build property development.

Although Room Below can trace its roots back to 1979, we constructed our first basement room in London 22 years ago. We acted as a specialist subcontractor tasked with building a two storey basement under a row of terraced houses which now forms the utility and dining areas of one of London's premier designer boutique hotels.

Our founder, John Mullarkey, is still the Managing Director and also the inspiration and founder of ASUC, the Association of Specialist Underpinning Contractors, which was formed in 1992. The other founding members were Roger Bullivant and Michael Ellis.

We have no mission statement, no corporate mumbo jumbo, just 22 years of practical experience in how to engineer and build the very best basement rooms money can buy.
