Commercial Extensions

Commercial extensions require careful coordination to minimise disruption while your business continues trading. We've delivered office extensions, retail expansions and additional workspace for plant rooms, welfare facilities and back-of-house operations across Southern England and the capital.

Every commercial extension project we undertake complies fully with building regulations, Construction (Design and Management) Regulations 2015 (CDM) requirements and your operational constraints. Our project managers work closely with you to schedule works around your business hours, phasing delivery to keep disruption to an absolute minimum while maintaining safety and quality standards throughout.

Commercial Building Conversions & Change of Use

Commercial building conversions often present the most cost-effective route to optimising your premises, whether you're adapting existing space or exploring change-of-use opportunities. We understand the regulatory landscape around commercial property alterations and work proactively with Building Control to ensure your project progresses smoothly through each compliance checkpoint.

Our commercial property development expertise includes:

  • Office-to-alternative commercial use conversions.
  • Warehouse and industrial unit transformations.
  • Internal reconfiguration to improve workflow and productivity.
  • Structural alterations and load-bearing assessments.
  • Fire safety upgrades and accessibility improvements.

Each project benefits from our experience navigating planning requirements, building regulations and sector-specific standards that govern commercial property alterations. We'll guide you through the entire process, managing consultations with surveyors, structural engineers and statutory bodies on your behalf.

Integrated Plumbing & Building Expertise

What sets DMA apart is our foundation as commercial plumbing specialists who've expanded into full building services. This background gives us a strategic advantage when delivering commercial property development projects where mechanical services need to integrate seamlessly with structural works.

By handling both commercial fit-out and refurbishment disciplines in-house, we compress project timelines, eliminate coordination delays between trades and reduce the risk of compatibility issues that often emerge when multiple contractors work independently.

For facilities managers and developers, this translates directly into faster project delivery, fewer site meetings and clearer accountability when things need to move quickly.

Commercial Case Studies & Proven Experience

Our commercial building contractors have delivered projects across diverse sectors, giving us the breadth of experience to handle complex requirements with confidence.

Our commercial refurbishment contractors have completed work ranging from toilet block renovations at Fourneaux de France through to commercial plumbing installations for new offices in Battersea Square.

We've also managed water heater replacements at Cranborne House and delivered commercial plumbing infrastructure for luxury residential development in Wimbledon.

Each case study demonstrates our capability to work in demanding environments, maintain professional standards and deliver projects that meet both operational and compliance requirements. These aren't marketing exercises; they're evidence of our track record managing real-world commercial challenges from initial survey through to final sign-off.

Health, Safety & Commercial Compliance

Professional commercial building contractors operate to standards that give landlords, managing agents and business owners complete confidence in both process and outcome. We maintain full CDM awareness across our team, conduct thorough risk assessments and provide detailed method statements before work begins.

Every project complies with current building regulations, and we're experienced in working within live commercial environments where safety protocols must be rigorously maintained while minimising disruption to staff, customers and ongoing operations.

Our commercial refurbishment contractors understand the professional standards expected across different sectors, from healthcare and education through to hospitality and retail. We deliver commercial property alterations that satisfy both statutory requirements and the practical realities of running a business during construction phases.
