Leading the way to make the construction industry more responsible in terms of our environment, communities, and workforce

Harmonix’s mission is to incorporate sustainable practices into all aspects of our business to fulfil our responsibilities to our environment, clients and employees whilst maintaining the high levels of working standards and quality we’re best known for. We define sustainability in a broad context, encompassing not only the environment but also the communities we work within and the people whose work we rely on to succeed.

AT HARMONIX CONSTRUCTION, WE ACKNOWLEDGE THAT THERE IS ALWAYS ROOM FOR IMPROVEMENT

To ensure we maintain our focus on this, all our projects are registered with the Considerate Constructors Scheme (CCS).

The scale and effects of the construction industry are enormous, so we endeavour to make improvements wherever practical. Through partaking in the scheme, we feel that these targets are achieved more effectively.

Featured Projects

“I used to think a project had gone well if you were still on speaking terms. Harmonix has shown that you can actually like your contractor. Their straightforward, pragmatic approach is welcome, and the quality of the finish has been superb. Our project was led by Troy, who we have found to be very impressive. Troy has an almost obsessive eye for detail and a broad industry knowledge. He is also unafraid to ruffle a few feathers (including ours) when required. Steve, our site manager, juggled endless coordination and subcontractor issues with expertise and a smile. ”

Will McCullagh, Vanguard Holdings Limited

“It was refreshing to have a scheme completed with a minimum of snagging and on time, a great achievement of everybody involved but especially of your site Team. I am very pleased that the Client is happy and that the units are letting.”

Miso Marlais, Ian C King Associates Architects

“Harmonix bring a diligent approach to all projects overcoming obstacles encountered with a proactive approach and a willingness to find good cost-effective solutions. We would be happy to recommend Harmonix Construction as a reliable and professional contractor.”

Nick Mayger, PQS – Peter Lawrence Stallworthy

“Our experience of working with Harmonix is that they provide a high-quality product, on time and within budget. The Harmonix team are professional, communicate well with their client, offer solutions not problems and most importantly hold H&S in the highest regard whilst maintaining a clean and tidy site even with difficult site logistics. “

Darren Kennett, Project Director - Kier Property

“The scheme was dealt with in a professional and trustworthy manner, with the team successfully completing the works to a high standard. We are looking at further work with Harmonix to continue our working relationship”

Lewis Trevellyan, Director – Trevellyan Developments Ltd

“Harmonix are a diligent contractor with a proactive approach to programme and commerciality to ensure their client’s requirements are met at all times. I have no hesitation in recommending them and expect to use them again for upcoming projects in the near future.”

Henry Gould, Head of Property & Acquisitions – Precis Advisory Limited

“From start to finish the team at Harmonix attention to detail has been impeccable and they have shown a great understanding of the product we aspire to”

Ken Fennell, Head of Facilities – Abellio London Ltd

“Harmonix has successfully delivered Chertsey Business Park for Chancerygate and the quality of the finished product is excellent. The development was challenging in number of ways and the Harmonix team worked collaboratively with all stakeholders throughout the construction process to ensure the project was delivered on time and budget. Their approach to dealing with Covid-19 pandemic deserves a special mention as this was all taken in their stride and working practices were quickly adapted to ensure that the overall programme was not affected. I hope to work with Harmonix again soon and build on this success.”

Matthew Storr, Project Manager - Chancerygate
