Our process

Contact us for a free indication, without obligation. If our indicated cost suits your budget, we then organise a full site visit. This includes a survey of the property, drainage and structure to ascertain a clear, full, fixed price quotation for you. 

There is a small fee, project dependant, for this service which will be removed from the final price of any work completed by Substructure Developments Ltd.

At Substructure Developments Ltd, we like to offer a supportive approach to working with our clients whether this be through assisting in the design of a new project, selection and sourcing of materials, guidance in keeping budgets on track or ‘brainstorming’ on how best to fulfil a vision.

Founded in 2007 by Mitchell Hughes, Substructure Developments Ltd has grown to be one of the most respected building contractors in Maidenhead, Windsor, Ascot, Bagshot and the surrounding areas, producing high-end finishes, excellent client relations and with Mitchell's years of experience across all trades, he has contributed to stunning elements within his projects that were not at first considered.

We provide free indications for all our jobs and understand that keeping the work environment tidy, respecting the neighbours and finishing on time is as important as the job itself, and that your satisfaction is key to the success of our business.

I am a great believer that ‘quality isn’t expensive – it’s priceless’ and I pride myself on this ethos.

When I started Substructure Developments Ltd, I wanted to do things differently to others. Our focus always has and always will be on customer satisfaction and the quality of the work we put out there, ensuring a smooth and positive build experience for my clients.

I appreciate that people can feel apprehensive about making, in some cases, very major changes to their properties and therefore I ensure very open levels of communication at all times – 7 days a week.

My previous clients are so proud of the work that we have completed that they are happy to open up their doors to potential new clients to share the results.

With such positive client relations our main source of work is now through recommendation and we pride ourselves on being a very tight-knit team offering support and guidance throughout all works we produce, whether big or small, across all disciplines.

Contact us today to discuss your project and we will happily provide you with a free indication.

Kind Regards,
