Basement specialists for Northern England’s premium homes and residential projects

Engineering-led basement delivery with premium finish in mind.

Basement Structures North delivers bespoke shell and core basements, basement fit-out, finishing and turnkey basement rooms across Northern England for luxury homes, complex residential projects and premium developments.

With 30+ years of basement delivery experience, we combine technical construction expertise with design-aware project management, working alongside RIBA architects, chartered engineers, interior designers, contractors and private clients to create robust, beautifully realised underground spaces.

Our approach is built around the areas that matter most in below-ground construction: surveys and investigations, design coordination, temporary works, excavation, structural construction, waterproofing, MEP coordination, and where required, complete fit-out and turnkey delivery.

Creating discreet additional space below ground

Across affluent areas of Cheshire, Leeds, Harrogate, Ilkley, Windermere and the wider Lake District, many clients want to create more space without compromising the appearance, character or setting of the main property. Basements offer a discreet, high-value way to add space where above-ground extensions may be undesirable, restricted or visually intrusive.

Basement Structures North is positioned to support both professional teams and private homeowners. We can deliver a technically robust structural basement package, or take projects forward into fit-out, finishing and fully turnkey underground living spaces.

Whether the brief is a new-build basement, retrofit basement, garden basement or completed lifestyle space, we coordinate the process so structure, waterproofing, services and finishes work together from the outset.

Who we are — specialist basement contractors, not general builders

We focus specifically on the specialist disciplines that underpin successful basement projects: basement engineering, temporary works coordination, excavation, structural construction, waterproofing design and installation, and the careful integration of services and finishes.

That specialist focus allows us to work confidently on architect-led homes, complex sites and premium residential developments where risk management, sequencing, waterproofing performance and quality of finish all matter.

Basement Structures North is a trading name of Innovative Structures Limited, bringing together technical credibility, construction management discipline and a premium approach to completed underground spaces.

30+ years delivering basements

BS 8102:2022 waterproofing designed by a named CSSW specialist

Long-term basement performance depends on the waterproofing strategy being right from the start. We coordinate waterproofing design to BS 8102:2022, typically combining robust structural solutions with maintainable systems suited to the project.

  • Design input from a named CSSW specialist
  • Coordination of joints, penetrations and maintainability
  • Integrated thinking from structure through to final use of the space

Temporary works procedures to BS 5975-1:2024

Below-ground construction demands careful sequencing and control. We manage temporary works procedures with appointed TWC/TWS, helping projects progress safely and logically through excavation, support and structural delivery.

  • Excavation and support planning
  • Risk-managed sequencing and hold points
  • Monitoring and protection of adjacent structures where required

Design coordination, compliance and stakeholder support

Premium residential basement projects often require more than structural delivery alone. We support coordinated project teams with design input, logistics planning and documentation suited to sensitive sites and complex approvals.

  • BIA, CTMP/CLP/CMP, Section 61 and CoCP support where required
  • Coordination with architects, engineers and consultants
  • Considerate delivery on high-value residential sites

What we build

We support projects from early feasibility through to completed below-ground environments. That can mean a technically demanding new-build basement, a discreet retrofit basement, a carefully planned garden basement, or a fully realised underground space delivered with fit-out, finishing and turnkey handover.

For homeowners, that may become a home cinema, gym, wine cellar, spa, games room, guest suite or family space. For professional teams, it means working with a specialist contractor that understands complex excavation, reinforced concrete structures, waterproofing coordination and high-quality residential delivery.
