For this anonymised project in Wakefield, the goal was to create a premium leisure space that combined a new above-ground extension with a structurally robust basement below. The completed concept provided a dedicated golf simulator room and games/entertainment space, while preserving the quality and appearance of the home and garden above. We delivered the shell & core basement package and extension structure, starting with surveys and investigations, progressing through excavation, reinforced concrete construction, structural coordination, and a BS 8102:2022-aligned waterproofing strategy designed by a named CSSW specialist. Because this type of leisure basement depends heavily on ceiling height, clear spans, AV/data provision, ventilation and dry internal conditions, the project demanded careful interface planning so the specialist simulator and interior fit-out package could follow on cleanly.
Who this case study is for
- Homeowners: how a new extension and basement can create discreet leisure space for golf simulation, games and entertaining.
- Professionals: structural, waterproofing, temporary works and fit-out interface considerations for a residential extension with basement below.

Project snapshot
| Item | Detail | Why it mattered |
|---|---|---|
| Location | Wakefield, West Yorkshire | Established residential setting requiring tidy logistics, controlled deliveries and considerate site management. |
| Property type | Private residential home with new extension and basement below | The structure had to work as a combined above- and below-ground package, not as separate elements. |
| Scope (our role) | Shell & core basement construction + extension structure + waterproofing coordination + builders’ work for MEP/AV interfaces | We delivered the robust structural container and fit-out readiness for the specialist leisure interior package. |
| End use | Golf simulator room + games/entertainment space | Ceiling height, span control, acoustic separation, ventilation and service routing were all critical. |
| Key constraints | Residential access, structural integration, waterproofing continuity, fit-out coordination | Early coordination reduced the risk of rework once simulator, AV and finishing trades mobilised. |
| Delivery focus | Dry, accurate, well-coordinated shell for follow-on fit-out | Leisure basements depend on precise interfaces and a stable internal environment to protect equipment and finishes. |

The brief
Homeowner priorities
- Private leisure space for golf simulation, games and entertaining without compromising the main living areas above.
- Discreet additional space: create usable square footage below ground while integrating a high-quality extension above.
- Comfort and performance: a dry, quiet, well-ventilated environment suitable for premium finishes and specialist equipment.
- Long-term confidence: a structure and waterproofing strategy designed properly from the outset rather than treated as an afterthought.
Professional requirements
- Integrated structural package: the extension and basement had to be designed and built as one coordinated scheme.
- Waterproofing strategy: aligned with BS 8102:2022 principles and coordinated with penetrations, joints and service entries.
- Temporary works governance: procedures aligned to BS 5975-1:2024 with appointed TWC/TWS.
- Fit-out readiness: builders’ work openings, power/data routes, ventilation provision and acoustic considerations needed to be anticipated early.
Site context in Wakefield
Wakefield combines established residential neighbourhoods, varied plot conditions and the practical challenges that come with delivering complex structural work in live domestic settings. On projects like this, success depends not only on the structure itself, but also on how carefully access, excavation, deliveries and follow-on trades are managed.
This project required calm residential logistics, protection of surrounding areas, and clear coordination between the basement shell works, the extension structure above and the specialist interior package to follow.
Technical overview (extension + basement shell)
Structure, excavation & span control
A golf simulator and games room below a new extension calls for precise structural thinking. We coordinated the reinforced concrete basement shell, load paths above, clear internal geometry, and builders’ work requirements so the space could receive specialist leisure fit-out without compromise.
Waterproofing & dry environment performance
Leisure basements rely on a dry, controlled internal environment. We coordinated a BS 8102-aligned waterproofing strategy with attention to joints, penetrations, upstands and maintainable details so specialist finishes, flooring, AV equipment and joinery would be protected.
MEP, AV & ventilation readiness
Golf simulation rooms depend on reliable power, data, lighting control and ventilation. We planned early for MEP coordination, including builders’ openings, service zones, extract/supply routes, equipment locations and practical access for future maintenance.
Neighbour-ready delivery
Residential projects are judged by the quality of delivery as much as the finished result. We used controlled logistics and considerate site management to keep the works organised, tidy and predictable throughout the structural phase.
Our process (from concept to fit-out-ready shell)
1) Surveys, investigations & design coordination
The starting point was confirming how the extension above and basement below would work together structurally and spatially. We coordinated surveys and investigations, checked buildability, reviewed access, and worked through early requirements for ceiling height, room proportions, stairs, ventilation and specialist equipment zones.
2) Enabling works & logistics planning
Before excavation began, we established access arrangements, protection measures, material sequencing and safe segregation of work zones. On high-quality residential schemes, tidy logistics and predictable site behaviour are essential from day one.
3) Excavation & temporary works
Excavation was carried out under formal temporary works procedures, with appropriate support, sequencing and hold points. This helped protect the surrounding property, maintain safety and keep the structure on programme.
4) Basement shell and extension structure formation
We formed the basement base, retaining walls and structural shell below while coordinating the extension structure above. The aim was to create a robust, accurate container with the right openings, tolerances and load paths for the space to function properly once fitted out.
5) Waterproofing strategy implementation
We coordinated the waterproofing design intent across joints, penetrations, upstands and service entries, treating the system as a critical performance layer rather than a later add-on. This is especially important where premium finishes and electronic equipment are planned.
6) Service, ventilation and fit-out interface coordination
A golf simulator room has different demands from a standard basement room. We prepared the shell with the necessary builders’ work for power, data, ventilation and specialist equipment interfaces, helping reduce clashes and rework during fit-out.
7) QA, handover & readiness for finishing
Before the interior package proceeded, we completed structured QA and handover checks, ensuring the shell was properly prepared for specialist simulator installation, games room fit-out and premium interior finishing.
Outcome
For the homeowner
- A discreet, high-value leisure space combining a new extension with a premium basement below.
- A layout suited to golf simulation, games and entertaining without sacrificing the main house above.
- Confidence that the structural and waterproofing strategy had been coordinated properly from the start.
For the professional team
- Integrated structural delivery across both the extension and basement package.
- Fit-out interfaces considered early, including service zones, access, ventilation and specialist equipment needs.
- Temporary works, QA and handover handled in a controlled, professional manner.

Wakefield Golf Simulator & Games Room — FAQs
Yes. This type of arrangement is often a very efficient way to create premium leisure space while keeping the main house and garden layout intact. The key is early coordination of structure, waterproofing, ceiling height, ventilation, power and access.
Ceiling height, clear internal geometry, load paths, tolerances and the relationship between the extension above and the basement below are all important. It is also essential to lock down penetrations and builders’ work before the shell is complete.
These spaces often include premium finishes, AV systems, specialist flooring and bespoke joinery. A dry, stable environment is essential, so the waterproofing strategy must be coordinated carefully with structure, drainage, penetrations and maintenance access.
Yes. We aim to bring forward the information that matters most — equipment zones, ceiling allowances, lighting positions, ventilation routes, power/data requirements and access — so the shell is prepared properly before the fit-out team starts.
Yes. We support both structural basement construction packages and, where required, further coordination into fit-out, finishing and turnkey basement room delivery.
