Underground Garage Construction London





Underground Garage Construction London
Space is scarce in London, and secure parking is at a premium. For homeowners in areas such as Kensington, Chelsea, Hampstead, and Westminster, a luxury underground garage is a practical way to gain off-street parking, protect valuable vehicles, and enhance property value — without altering your home’s appearance above ground.
With over 30 years of experience in basement construction London, Basement Structures design and build bespoke underground garages with full structural integrity, car lifts, and advanced waterproofing systems. Every project is engineered to BS8102 standards and delivered by a single accountable design-and-build team, ensuring long-term protection and seamless integration with your property.
Waterproofing — Protecting Your Investment
Moisture control is critical when housing high-value vehicles underground. Basement Structures’ waterproofing design combines Type A (barrier), Type B (integral), and Type C (drainage) protection — a multi-layered system proven across hundreds of London basements. Our installations often include cavity drain membranes, perimeter channels, and twin-pump sumps with alarms and backup power to guarantee 24/7 protection against groundwater ingress.
Every waterproofing system is installed and certified by accredited technicians and verified by independent basement impact assessments where required. This meticulous approach ensures that your underground garage remains dry, secure, and durable for decades to come.
Luxury Car Storage — Designed for London Living
For collectors and enthusiasts, a basement garage is not just about storage — it’s about presentation and protection. From humidity-controlled environments and polished resin floors to bespoke lighting and display turntables, Basement Structures deliver spaces worthy of your collection. Hydraulic car lifts and automated gates allow discreet street-level access while maximising limited urban footprints.
