Masters Group delivers commercial construction across Brighton and East Sussex, covering office refurbishments, retail fit-outs, restaurant and hospitality builds, light industrial unit construction, and mixed-use developments. Our work ranges from strip-out and refit of existing spaces through to ground-up commercial new builds. This service is for business owners, landlords, and developers who need commercial space built or refurbished to a professional standard within a defined budget and timeline. It is for restaurant owners fitting out a new premises, retailers creating a brand-consistent store environment, or office managers reconfiguring workspace for hybrid working. Commercial construction has requirements that residential work does not. Fire compartmentation, DDA (Disability Discrimination Act) compliance, commercial-grade mechanical and electrical systems, suspended ceilings, raised access floors, and specific landlord or tenant responsibilities all add layers of complexity that require experienced management. Masters Group brings the same structured project management approach to commercial work that we apply to residential — one project manager, one fixed-price contract, coordinated trades, and regular progress reporting. The difference is that we understand commercial timescales are driven by lease commencement dates, opening deadlines, and revenue implications. ### Related Services - [Project Management](/services/project-management) - [New Builds](/services/new-builds) - [House Renovations](/services/house-renovations) - [Extensions](/services/extensions) ### Areas We Serve - [Brighton](/areas/brighton) - [Worthing](/areas/worthing) - [Eastbourne](/areas/eastbourne) - [Horsham](/areas/horsham) ## Why Delays in Commercial Construction Cost More Than You Think In commercial construction, time is revenue. Every day a restaurant is not open is a day of lost turnover. Every week an office is not occupied is a week of rent paid on empty space. Every month a retail unit sits unfinished is a month of competitor advantage lost. The financial consequences of construction delays in commercial projects are immediate and quantifiable. The most common cause of commercial construction delays is inadequate pre-construction planning. When the scope of work is not fully defined before contracts are signed, variations emerge during construction. Each variation requires pricing, approval, and potentially redesign — adding days or weeks to the programme. Regulatory compliance is the second major risk. Commercial spaces must meet fire safety requirements (compartmentation, emergency lighting, fire alarm systems), Building Regulations Part M (access and use — including DDA compliance), and often specific licensing requirements (food premises, licensed premises, change of use). Discovering these requirements mid-project causes delays and additional costs. Coordination between the landlord's works and the tenant's fit-out is a frequent source of conflict and delay. If the base build is not completed to the agreed specification (CAT A), the tenant's fit-out (CAT B) cannot proceed as planned. Masters Group manages both sides of this interface, ensuring seamless handover between construction phases. Our Process ## How We Deliver Every Project 1 ### Brief & Site Survey We review your brief, survey the premises, assess the base build condition, and identify any regulatory or structural constraints. 2 ### Design Coordination We work with your architect, interior designer, or brand consultants to translate design intent into buildable specifications. 3 ### Fixed-Price Contract A detailed contract covering all works, with a programme showing key milestones, handover dates, and penalty provisions if required. 4 ### Strip-Out & Structural Existing finishes removed, structural modifications completed, M&E rough-ins installed, and fire compartmentation established. 5 ### Fit-Out & Services Suspended ceilings, partitioning, flooring, M&E second fix, joinery, decoration, and specialist installations (kitchen equipment, AV systems, signage). 6 ### Handover & Certification Building control sign-off, fire risk assessment, O&M manuals, warranty certificates, and handover. Ready for your opening day. ## Why This Matters for Your Project ### Revenue-Focused Scheduling We build your programme backwards from your opening date or lease commencement, ensuring every day of construction is planned to protect your revenue timeline. ### Fixed-Price Certainty Your contract price is fixed. No provisional sums, no retrospective pricing, no budget creep. You know your total cost before work begins. ### Regulatory Compliance Fire safety, DDA, building regulations, EHO requirements — we manage all compliance as part of the contract, so you do not face enforcement delays post-completion. ### Minimal Trading Disruption For refurbishments of occupied premises, we phase the work to maintain business operations — working out of hours, in sections, or behind temporary screens. ### Single Accountable Contractor One contract, one project manager, one point of responsibility. No finger-pointing between trades when things need resolving. ### Commercial-Grade Standards Finishes, M&E systems, and fire safety installations built to commercial standards — not residential standards applied to a commercial setting. ## Commercial Construction: Specifications, Standards & Sectors Office fit-outs typically involve CAT A and CAT B works. CAT A covers the base build — raised access floors, suspended ceilings, basic M&E distribution, and fire protection. CAT B covers the tenant-specific fit-out — partitioning, bespoke joinery, branded finishes, AV systems, and furniture. Masters Group delivers both, whether you are a landlord preparing a unit for letting or a tenant fitting out your new space. Restaurant and hospitality fit-outs require specialist knowledge of commercial kitchen extraction systems, grease traps, fire suppression systems, and Environmental Health Officer (EHO) requirements. The kitchen extraction system alone — from canopy through ductwork to roof discharge — must comply with DW/172 for ductwork specification and provide adequate air change rates for the cooking equipment installed. Retail fit-outs demand brand consistency, durability under high foot traffic, and compliance with accessibility standards. We work from brand guidelines provided by your design team, translating visual concepts into physical builds using materials that withstand daily commercial use. Display systems, lighting, power and data provisions, and security installations are all coordinated within the fit-out programme. Light industrial and workshop builds cover everything from partition walls and mezzanine floors in existing units through to ground-up construction of new industrial premises. Structural steel, concrete floors capable of supporting heavy equipment, three-phase electrical supplies, and commercial heating systems are standard elements of these projects. Fire safety in commercial premises is governed by the Regulatory Reform (Fire Safety) Order 2005 and Approved Document B. Requirements include fire compartmentation between units, protected escape routes, emergency lighting, fire alarm systems, fire extinguisher provision, and fire risk assessment. Masters Group installs and certifies all fire safety elements as part of the construction contract. DDA compliance requires level or ramped access, accessible toilet facilities, appropriate door widths, hearing loop provision in reception areas, and tactile signage. We incorporate these requirements from the design stage to avoid costly modifications later. For existing buildings, we advise on reasonable adjustments that meet legal requirements without requiring major structural work. ## Frequently Asked Questions ### How much does a commercial fit-out cost? ### How long does a commercial fit-out take? ### Can you work out of hours to minimise business disruption? ### Do you handle building regulations and fire safety compliance? ### Can you manage both the landlord's works and tenant fit-out? ### Do you provide warranties on commercial work? ### What commercial sectors do you work in? ### Can you help with change of use applications? ![Professional construction project — Masters Group building contractors](/assets/cta-bg-CbvIn_eS.jpg) ## Ready to Build Your Commercial Space?
