Comprehensive Property Solutions
We deliver a holistic approach to property development. From complex subterranean engineering to the construction of entirely new residences, our portfolio covers eight key disciplines tailored to the high standards of SW12.
Premier Basement Services
Our flagship offering. We manage the entire lifecycle of your basement project, taking it from the initial architectural concept right through to the final interior finish. This is a turnkey service designed for clients who require a seamless, managed experience without the stress of coordinating multiple contractors.
Basement Redesign
The core of our expertise. We specialize in the heavy engineering required to create space where there is none. Whether we are excavating under a Victorian terrace or creating a new footprint in the garden, we handle the earthworks, temporary propping and soil removal with military precision.
Basement Building Solutions
For clients who have their own architects or designs, we provide the structural muscle. We focus on the shell and core works, delivering the concrete foundations, underpinning and steelwork necessary to ensure the absolute structural integrity of your property.
Basement Excavation Services
Layouts that worked ten years ago may not suit modern living. We re-imagine existing basements by moving structural walls and reconfiguring floorplans. We create open-plan family rooms, home cinemas or guest suites that flow logically with the rest of the house.
Basement Modernization
We breathe new life into older, tired conversions. If your existing basement suffers from low ceilings, damp issues or poor lighting, we intervene. We deepen floor levels, install state-of-the-art waterproofing systems and upgrade insulation to meet current building regulations.
Loft Conversion Specialists
Maximizing vertical potential is just as important as digging down. We are adept at creating master suites and home offices within the roof space. Coordinating a loft conversion alongside basement works allows for significant cost efficiencies and a unified design language throughout the home.
Home Extension Experts
Connecting the home to the garden changes everything. We build high-specification rear and side-return extensions. By opening up the back of the house with modern glazing, we create the expansive kitchen-diners that are highly sought after in the SW12 property market.
New Property Builds
Beyond renovations, we possess the capability to construct new residences from the ground up. We work with developers and private clients to build distinct, high-quality homes that respect the architectural vernacular of the local area.
How Basement Contractors Deliver
Construction in a dense urban environment requires a rigorous framework. We have refined our six-step process to ensure transparency, safety and adherence to Wandsworth Council’s strict guidelines.
Consultation & Feasibility
We begin with a site visit to assess the structural viability of your property. We discuss your requirements against the reality of the local soil conditions and architectural constraints, providing an honest appraisal of what can be achieved.
Planning & Statutory Approvals
We navigate the bureaucracy for you. Our team ensures your design complies with Wandsworth’s Supplementary Planning Documents (SPD), managing the Basement Impact Assessment and securing the necessary permissions to proceed lawfully.
The Party Wall Protocol
In terraced housing, protecting your relationship with neighbors is paramount. We facilitate the appointment of surveyors and manage the Party Wall Agreements to ensure all structural risks are documented and mitigated before work begins.
Excavation & Structural Engineering
The most critical phase. We secure the site and commence the dig utilizing conveyor belt systems to remove spoil efficiently through the front elevation. We execute the underpinning sequence meticulously to maintain the stability of the existing building.
Waterproofing & Mechanical Systems
A basement is only as good as its waterproofing. We install a Type C cavity drain membrane system with dual-pump technology which exceeds British Standards. This ensures your new space remains a dry, habitable environment regardless of ground conditions.
Fit-Out & Final Handover
This is where engineering meets design. We install underfloor heating, bespoke joinery and architectural glazing. We do not leave the site until the finish is flawless and you are presented with all necessary warranties and building control certificates.
Secure the Future Value of Your Property
Exceptional homes require exceptional care. If you are considering a basement excavation in SW12 or the surrounding boroughs, we invite you to discuss your requirements with our structural specialists.
Lightwells & Glazing Systems
The distinction between a standard basement and a luxury lower ground floor lies in the quality of light. We reject the concept of dark, enclosed spaces.
By integrating Walk-on Glass panels in the hallway above or designing expansive Rear Lightwells with bi-folding doors, we create a visual connection to the outdoors. For properties with front bay windows, we utilize front lightwells to create bright, habitable guest suites or executive home offices. Our goal is to make the lower ground floor feel as airy and inviting as the reception rooms above.
