Commercial Plumbing For Luxury Residential Development in Wimbledon

The Brief

DMA was contracted to carry out all plumbing works on this Wimbledon luxury residential project, which has been ongoing 11 years in planning and development. Having already worked successfully on other London-based commerical plumbing projects, including the Battersea Square office development, DMA were chosen for their strong reputation in reliability, communication, and on-site problem-solving.

The brief required DMA to:

• Install all mains water supply pipework throughout both properties

• Fit and connect plumbing to 15 bathrooms

• Coordinate plumbing runs to feed first and second-floor bathrooms from ground-floor mains

• Establish efficient riser systems and plant room connections for heating and domestic water

• Liaise with architects, designers, and multiple trades to ensure accurate fit to drawings

• Maintain high standards of workmanship suitable for luxury residential clients

DMA’s involvement on the project began in March 2025. There is no firm end date in sight for us, but we expect to complete all plumbing works by June 2026, if other stakeholders remain on schedule. To date, DMA is maintaining a dedicated on-site team of two to four engineers throughout.

Our Approach

DMA’s approach has been one of adaptability, accuracy, and collaboration – key qualities when working on complex multi-contractor developments. Our on-site team is led by lead engineer Steve Scott, who boasts over 23 years’ experience as a professional plumber. Supporting him is plumbing engineer Max Phillimore, who’s got five years’ experience. Both Steve and Max have demonstrated an outstanding ability to manage technical detail while staying flexible to site challenges.

1. Technical Precision

DMA’s engineers are installing the mains supply running across the ground floor, routed above the basement. The sub-basement plant rooms act as the operational hub, housing the central water distribution and heating systems, including the electrical and HVAC equipment.

DMA ensured the correct routing and isolation of mains pipework to safely integrate with the underfloor heating system – although not directly responsible for installing the underfloor heating, DMA’s precise connections were critical to its functionality.

All pipework is being installed using press fitting technology – a modern, solder-free method that ensures clean joints and long-term leak prevention. These fittings are so good, they come with a 20-year warranty, and are the new standard for large-scale plumbing jobs, guaranteeing water system functionality and durability.

2. Coordination with Other Trades

As with most large commercial plumbing projects, coordination was essential. With approximately 15 contractors working on-site at any given time, DMA’s engineers need to navigate scheduling clashes and limited access to working areas.

At times, electrical cables were installed before plumbing runs, requiring rework and re-coordination. Despite these setbacks, DMA’s team handled each challenge professionally, working collaboratively with electricians and builders to maintain project momentum.

3. Overcoming Design Changes

Late-stage design alterations introduced by architects and interior designers meant that bathroom layouts and wall positions were occasionally modified after pipework had already been installed. This required DMA to remove and refit certain sections of pipework to align with the updated specifications – a demanding but not uncommon task in high-end bespoke developments.

Thanks to their can-do attitude and deep technical knowledge, Steve and Max were able to adapt quickly, ensuring all installations remained compliant with the revised designs and building regulations.

Project Challenges

Working away from their Poole-based headquarters presented additional logistical and personal challenges for the DMA team. With engineers regularly staying in temporary accommodation around Morden and Croydon, site rotations typically ran in two-week blocks.

Despite the demands of travel and time away from home, DMA’s engineers maintained the company’s high standards and professionalism.

Lead engineer Steve described the project as “challenging but rewarding” due to its scale, design complexity, and the collaborative nature of the build.

Bath Gate, the larger of the two homes, features a basement plant room, open-plan ground floor, and swimming pool (installed by another contractor). DMA’s current focus is completing the first-floor bathrooms, with work on the second-floor sanitaryware to follow once structural amendments are completed by the main builders.

Results and Progress

By autumn 2025, DMA had successfully completed nearly all plumbing installations across the ground and first floors of Lincoln House, preparing for the testing and commissioning phase.

Work on Bath Gate continues in parallel, with DMA carefully sequencing tasks to stay aligned with the evolving construction schedule.

Although completion is anticipated for mid-2026, the project already demonstrates DMA’s strengths in:

• Delivering complex plumbing systems on large-scale sites

• Working to high-end luxury standards expected of multi-million-pound residential properties

• Collaborating effectively with architects, builders, and subcontractors

• Problem-solving under pressure, ensuring deadlines are met despite unforeseen changes

The project reinforces DMA’s growing reputation as a trusted partner for commercial plumbing contracts in London and the South of England.

Looking Ahead

DMA’s involvement in the Wimbledon development highlights their expanding role in London’s luxury residential and commercial plumbing sector. With a reputation for technical skill, reliability, and commitment to excellence, the company continues to attract high-profile projects through word of mouth and repeat contracts with leading property developers and builders.

Whether handling bespoke homes, mixed-use buildings, or full-scale commercial developments, DMA’s team brings the same meticulous standards to every project – proving once again why they are among the leading commercial plumbing contractors in the South of England.

Client Feedback

According to the project team, the client and site managers have been impressed with DMA’s professionalism, consistency, and attention to detail. They noted that the DMA engineers have been exceptionally reliable and praised our clear communication and high standard of workmanship, particularly given the complex coordination demands of the development.
