Property renovation in London


SigmaLondon provides luxury residential refurbishment services for Central London properties. Our company specialises in high-end contemporary renovations, refurbishments and extensions to homes and investment properties. Property refurbishments can be carried out in many ways and based on various projects. Regardless of whether the client is interested in the kitchen or bathroom renovation, or full house remodelling, the project must be finished on time, within the budget and according to the schedule. That is why it is worth hiring experienced, high-end residential contractors in London. Although many new homes adapt easily to remodelling projects, older homes may require special care and attention to details. Our company has a lot of experience in this field and therefore we provide high-quality services for both new and old houses. Our experienced and dedicated craftsmen work under the close supervision of our project management team and to detailed documentation and specification provided by architects and interior designers.

We believe in offering comprehensive building services and understand that working together coherently and cohesively is the best way to ensure the final quality of the design intent. Excellent design cannot be executed without a talented workforce and our aim is to always find the best, most reliable specialist, sub-contractors and suppliers. We provide ideas and concepts for interior design solutions that meet the expectations of the most demanding clients. We approach each project individually and make sure that the client’s idea of modern refurbishment is fully achieved. Many years of practice and knowledge gained from the ongoing work of property renovation in London allow us to constantly develop and create truly spectacular projects. Our company guarantees professional advice and guidance. We provide our knowledge at every step of the renovation process – starting with planning and creating the budget. Our mission is to achieve full satisfaction of the client and create a space that will meet their expectations.


We undertake commissions on the following types of projects:

Full home renovations - involving stripping the property back to bare bricks and rebuilding it, to include new plumbing, electrical work, new staircases, removing and repositioning walls and partitions to suit the architect’s design intent to achieve optimal layout. Our company provides full, complex projects and both standard and unconventional interior design solutions.

Extensions and side returns - to accommodate open-plan kitchen-diner-living spaces connecting to the back garden, to include all kitchen cabinetry, fixtures and fittings.

Loft conversions - maximising the efficiency of London homes by utilising unused roof space and reconfiguring the tectonics of the traditional floor plate. In addition to work on the ridgeline and height of the roof, this often requires additional work to reconfigure the main stair, bathroom provision, hot water supply and work to the chimney stacks. We turn roof spaces into comfortable residential flats that are truly spectacular.

Bathroom design and fitting - a general bathroom renovation consists not only of replacing old tiles or devices with new ones. A new bathroom may require new plumbing installations or changing the place of sanitary facilities, bathtub, shower cubicle or installing new lighting points. We make sure that the new bathroom is not only elegant but a lot more ergonomic and functional than the current one. Our company provides renovation of existing bathroom layouts, introduction of wet rooms, additional bathrooms and more compact water closets or cloakrooms as space permits.

Kitchen design and fitting - 21st living has typically repositioned the kitchen back to the heart of the home. Renovating the kitchen may be as simple as changing countertops and kitchen cabinets, but it can also be very complex and require a complete reconstruction of the space, which is not a simple thing to do. Our company provides assistance in creating the project, professional support and advice, as well as a wide range of non-standard solutions for the client to use. Clean and efficient styling paired with bespoke crafted cabinetry and preparation spaces will refresh your home.

Bespoke joinery - purpose built cabinetry, wardrobes, dressing areas and vanity units provide that extra level of bespoke tailoring for our clients. We provide classic and unconventional designs for every type of space that meet our clients’ needs and expectations.
