If you are thinking of converting your basement or cellar, MCG Group Services has the experience and expertise you need to design and build a stunning new space in your home. Our trusted and reliable builders have delivered first class basement conversions to properties of all sizes throughout Brighton and across Sussex.



Whether you are renovating your family home or you are a developer flipping a property, basement renovation can provide new, useable space to a property. Converting your basement can also add considerable value to your home. At the same time, basement or cellar conversions are a cost-effective alternative to building a home extension, which can reduce the amount of outdoor space on your property.

MCG Group Services, a trusted Brighton basement company, offers a range of basement design and building services to our clients. From basement excavation and tanking to designing and building cellar conversions and sub-basements, we offer the expertise you need to create liveable and functional basements.

We are a full-service construction company in Brighton, and we can handle all types of projects regardless of how complex or simple they may be. In addition to designing and building basement conversions, our experienced builders in Brighton can raise and lower existing floor levels, design and build staircases and windows, and undertake structural steel work to create the best possible space for your property. They can also handle projects involving underpinning and temporary propping of existing structures. MCG Group Services also fits effective insulation, provides waterproofing and fits drainage systems for basement conversions to optimise comfort and safety.

We recognise the importance of local education establishments for future generations, and one of the most pertinent factors towards gaining an excellent education is the environment in which we learn.

What sets us apart?

It’s a difficult objective to achieve in the modern construction business: setting yourself out from the crowd and making your name known. That said, here at MCG Group, every day that passes by is another day of happy custom, critical praise and improvements in our local reputation: the only way to set yourself apart from the rest is to do it best, and keep doing it best.

With our eco-friendly, ethical approach to all construction projects (something we believe is especially important in our education construction work, as future generations are the ones that must carry the environmentally friendly torch) and our passionate drive to leave our mark on all builds – you can rest assured that MCG Group education projects will go unsurpassed.
