About Mason Projects London

We have a catalogue of photographs that show the type of work we produce, ranging from specific carpentry jobs such as bespoke American black walnut walk-in wardrobes to complete open plan extensions and large scale refurbishments, right up to virtual new build.

We come from a background of NHBC registered new build companies and constructed blocks of flat, inner London basements and so on. Our area of expertise is all manner of extensions, loft conversions and everything in between in terms of refurbishment work including kitchens and bathrooms.

We are fundamentally two brothers who have drawn upon years of working for successful property developers and cherry picked all of the highest quality tradesmen we have encountered over the years and grown to know and trust first hand. From there we have both worked individually for other successful builders and developers across Surrey. We know that our care and attention to detail is what sets us apart and our work ethic is unparalleled. If this is the type of builder you are looking for then please get in touch.

All of the tradesmen we use from plumbers to electricians to steel fitters are fully qualified, insured and licensed in accordance with the relevant recommended bodies (Gas Safe, ELECSA, NICEIC etc). If you have a specific query please enquire.
