All of our basement conversions come with a 30-year warranty on Delta Membrane Systems waterproofing.
As experienced builders with many years under our belts, the SDA Team have often been called in to fix many a botched project, and sadly one of the most common botches is poor waterproofing.
It’s shocking how many properties across South West London don’t have the correct waterproofing installed when completing a basement conversion, and sadly homeowners and developers won’t realise this until it’s too late and their basement is water damaged or flooded by ground swell!
For this very reason, SDA Build London is proudly accredited by the UK’s leading waterproofing brand, Delta, with all our basement conversion projects installing their cutting-edge Delta Membrane Systems.
This high-density polyethylene covering is applied to the walls, floors and ceilings of a basement dig out, where it blocks, controls and drains any potential ground water ingress from entering a property. It can be applied to new, existing and retrofit projects, and is flexible and durable so it can cope with movement or vibration in the home – important as this is often the cause of basement flooding! All our Delta Membrane installations come with a 30-year warranty that ensures your basement is protected.

As we mentioned in our recent piece on Fulham property trends in 2018, the recent downturn has seen many property owners across South West London maximising their home’s value with extensions and loft conversions. But for many that are unable to extend their homes due to planning applications, building regulations or limited space, there’s only one solution: to build downwards!
We love doing basement excavation, especially in London. This is for a good reason: we’re generally able to build roomy open areas that give our clients the freedom to create their perfect living space, while keeping the structural integrity of the building. Better yet, moving certain rooms into the basement (like the utility room or downstairs bathroom) allows the ground floor of a home to expand out. In conjunction with even the smallest of rear or side extensions, it can completely transform a modest home into a spacious abode.
The SDA Build team have picked some of our favourite London basement projects below – and if you feel inspired by any of them or want to talk to a project manager about what we can do with your home (we can even add swimming pools!),
Basement Cinema and Wine Cellar Conversion
Our most recently completed project in Chelsea saw the team really showcasing our skills in designing and excavating to create a stunning basement space. In addition to a full refurbishment of the home, the client wanted to create an environment designed to entertain guests. We began by reinforcing the property with an internal steel frame, allowing us to dig out the basement to create two large rooms: a wine cellar that also acts as a second living room, and a cinema room designed to be accommodate up to 10 people. The spaciousness of the basement is further amplified with the long walls, bright decor and an open staircase allowing plenty of natural light into the wine cellar.
Basement Bar in the Garden
The brief for this project in Wandsworth was to add a private bar area to the garden of this home that felt like a natural extension of the garden. With no permission to extend the property above ground, SDA Build London dug underground. We ensured the basement bar never felt detached from the rest of the garden by allowing natural light from the garden to always shine through, with an open design that utilises the same colour palette as the garden itself.
Entire Floor Dig Out – a Brand New Basement Building
The most extensive basement conversion of them all, this type essentially adds an entire floor to a property that can extends out the entire length of the home and garden. For the Fulham terrace property in the images below, the basement conversion allowed the owner to relocate their living room, a home office and a luxurious en-suite guest bedroom to the basement, freeing up the ground and 1st floor to become more spacious.

South West London is home to some of the most inspired property renovations, restorations and refurbishments in Europe, where homeowners, architects and builders often have to overcome the challenge of limited space through genius design and creativity. In the first of a series of articles looking at 2018 property renovation trends across South West London, we take a closer look at Fulham:
The Fulham property market is in the process of change
2017 saw London facing a dip in the property sales market, as foreign investors began to exercise caution when investing in the Capital. Fulham was no exception to this, with a 10% dip year-on-year in sales, 4% higher than the London average. Almost in immediate response, the Fulham market has since shifted away from luring foreign investment to instead trying to accommodate for London’s growing demand for family-friendly homes.
With desirable mortgage rates and adjusted house prices, Fulham is seeing the first post-recession spike for 3+ bedroom prime residential properties between £0.8M and £1.5M. New builds across the river stretch – like the Fulham Reach and Fulham Riverside projects – are aiming to transform the area in the “new Chelsea”, where properties with more rooms and living space command higher valuations. This has seen the whole area change attitude, where existing homeowners and developers are now looking at how to maximise room count and space! There has also been a cultural shift in Fulham, with areas like Parsons Green and Walham Green seeing the young-and-hip residents of yesteryear settling long-term in the area as they now raise their families.
Rear extensions
Easily the most common type of property renovation in Fulham, many of our clients in the area look to capitalise on the relaxed permitted development rights. The majority of detached and semi-detached homes in Fulham are allowed to add 6 to 8 metre single-storey rear extensions to their properties without requiring planning permissions. Some exceptions apply – speak to us if you’re unsure of your home’s status – but the additional space can be truly transformational.
We’ve noted savvy homeowners are relocating their kitchen, dining area and living space to their rear extension, typically as an open-space, freeing up the former front room into an office space or additional guest room.
Basement conversions and loft conversions
For homes unable to do a full rear or side extension, homeowners are instead opting to build up – and down! Loft conversions are fairly standard in Fulham, converting typically wasted loft space into a master bedroom with en-suite, however many homes are now going underground. By expanding existing cellar space or digging out a new basement entirely, you add a floor to your property without needing to dramatically change the exterior of the home (which planning permission always likes to hear).
Our project on Dolby Road saw us transforming a terrace home in all directions, with the basement allowing the homeowner to move their utility room and downstairs bathroom into the basement. This freed up more space for a large party-friendly kitchen space, expanded with a small rear extension. With the loft conversion, the home transformed from a tightly compact 3 bedroom house to a spacious 4 bedroom luxury home.
Restoring multiple flats back into a single home
One of our most exciting projects in 2017 was restoring two flats on Quinsmill Road back into a single property. This was indicative of the trend in the area, where property value comes from having bigger homes, and it’s something SDA will be doing more of in 2018.
Converting commercial properties into residential homes
Recent years have seen Hammersmith and Fulham Council grant more permissions to convert typically abandoned or rundown commercial properties (often factory warehouses from Fulham’s industrial revolution past) into spacious homes and flats. This is something we see continuing in 2018, to meet the new demand.
