What We Deliver

TCM delivers the full scope of industrial and warehouse fit-out works — from a single mezzanine floor to a complete fit-out of a new distribution centre. Every project is managed by a dedicated project manager and priced on a fixed-price basis.

Mezzanine Floor Installation

Most Requested

Structural steel mezzanine floors that double your usable floor area without extending the building footprint. TCM designs, supplies, and installs mezzanine floors to suit your racking layout, loading requirements, and fire compartmentation needs. All structures are designed to BS 5950 and include staircase, handrail, and pallet gate as standard.

In-Warehouse Office Fit-Out

Common Scope

Partitioned office and welfare accommodation within the warehouse envelope — from a single manager's office to a full two-storey modular office block. Includes insulation, heating, lighting, data cabling, and WC facilities. Designed to keep the warehouse operational throughout the build.

Warehouse Partitioning & Segregation

Flexible

Steel partition walls, mesh caging, and demountable partition systems for creating secure storage areas, picking zones, temperature-controlled rooms, and hazardous materials stores. All partitioning is designed around your racking and forklift circulation requirements.

Racking-Ready Floor Preparation

Foundation Work

Concrete floor repairs, joint filling, surface hardening, and line marking to create a racking-ready floor that meets the tolerances required by your racking supplier. TCM coordinates with racking installers and forklift suppliers to ensure the floor specification is correct before racking goes in.

Industrial M&E Fit-Out

Full Service

Three-phase power distribution, industrial lighting (LED high-bay, emergency, and task lighting), compressed air pipework, HVAC for temperature-sensitive storage, and fire detection systems. TCM coordinates M&E design with specialist subcontractors and manages all building control submissions.

Fire Compartmentation & Compliance

Compliance

Fire door installation, compartment wall construction, fire stopping around penetrations, and sprinkler system coordination. TCM manages the full fire compliance package — from fire risk assessment through to building control sign-off — ensuring your warehouse meets the requirements of Approved Document B and your insurer.

Industrial Fit-Out vs Commercial Fit-Out: What's the Difference?

An industrial fit-out transforms a warehouse, factory, or industrial unit from a bare shell into an operational facility. The scope is fundamentally different from an office or retail fit-out: the primary concern is operational efficiency — racking layout, forklift circulation, loading dock access, and floor loading — rather than aesthetics.

The most common scope items in an industrial fit-out are a mezzanine floor (to create additional storage or office space without extending the building), in-warehouse office accommodation (partitioned offices and welfare facilities within the warehouse envelope), and M&E works (three-phase power, industrial lighting, compressed air, and fire detection).

What distinguishes a well-executed industrial fit-out from a poor one is the sequencing. The structural survey of the existing slab must come before the mezzanine design. The mezzanine column grid must be agreed before the racking layout is finalised. The M&E design must be coordinated with the racking layout before any containment is installed. TCM manages this sequencing as a matter of course — it is the reason our projects run on time.

For businesses taking a new industrial unit on a lease, the fit-out programme needs to be integrated with the lease start date, the landlord's Licence to Alter process, and the building control approval timeline. TCM manages all three in parallel — starting the design and building control submission process as soon as heads of terms are agreed, so that approval is in hand before the lease commences.

How We Deliver Your Fit-Out

01

Site Survey & Brief

We carry out a measured survey of the building and review existing structural drawings, M&E information, and planning history. We discuss your operational requirements — racking layout, forklift type, headcount, temperature requirements, and programme — and identify any constraints.

02

Design & Specification

We produce a scheme design, structural calculations (for mezzanines), and a full specification. We coordinate with your racking supplier, forklift dealer, and IT provider. We identify any planning or building control submissions required and agree the programme.

03

Fixed-Price Quotation

We produce a detailed, fixed-price quotation based on the agreed specification. No provisional sums for items within our scope. We identify long-lead items — structural steel, specialist M&E equipment — and agree a procurement programme.

04

Construction

Our in-house team carries out all groundworks, structural, and fit-out works. Specialist subcontractors for structural steel, M&E, and fire suppression are managed directly by TCM. We programme the works to minimise disruption to your operations — phased working and out-of-hours construction where required.

05

Commissioning & Handover

All M&E systems are commissioned and tested. Building control sign-off is obtained. We provide all O&M manuals, warranties, as-built drawings, and a building log book. We coordinate the racking installation and final line marking for move-in.

What Every Industrial Fit-Out Involves

CDM Regulations 2015

All industrial fit-out projects of significant scale are notifiable under the Construction (Design and Management) Regulations 2015. TCM acts as Principal Contractor on all notifiable projects — managing the Construction Phase Plan, coordinating subcontractors, and maintaining the Health & Safety File. For projects where a Principal Designer is required, TCM can coordinate that appointment.

Building Regulations

Industrial fit-outs require building regulations approval for structural alterations (mezzanine floors), changes to means of escape, fire compartmentation, M&E installations, and accessibility provisions. TCM submits full plans applications and manages building control inspections throughout the construction phase. We do not use the Building Notice route for complex industrial projects.

Planning Permission

Most internal industrial fit-out works — mezzanine floors, partitioning, internal offices — do not require planning permission. However, changes of use, external alterations, and works in conservation areas or on listed buildings may require consent. TCM checks the planning position at the outset and manages any required applications.

Structural Engineering

Mezzanine floors and structural alterations require design by a chartered structural engineer. TCM works with a panel of experienced structural engineers who specialise in industrial buildings. All structural designs are peer-reviewed and submitted to building control as part of the full plans application.

Fire Safety

Warehouses and industrial buildings are subject to specific fire safety requirements under Approved Document B and the Regulatory Reform (Fire Safety) Order 2005. TCM manages the full fire compliance package — fire risk assessment, compartmentation design, fire door specification, fire stopping, and sprinkler system coordination — ensuring your building meets both regulatory and insurance requirements.

Operational Continuity

Most industrial fit-out projects are carried out in occupied, operational buildings. TCM programmes works to minimise disruption — phasing the construction sequence around your operations, scheduling noisy or dusty works outside operational hours, and maintaining clear forklift and pedestrian routes throughout the build. We have delivered mezzanine installations in live distribution centres with zero operational downtime.

What Nobody Tells You About Industrial Fit-Outs

Mezzanine Floors: What You Need to Know Before You Buy

The most common mistake in mezzanine procurement is buying the structure before the floor loading has been confirmed. The floor loading of the existing slab determines the column grid, which determines the mezzanine layout, which determines the racking layout. Getting this sequence wrong means expensive redesigns. TCM always starts with a structural survey of the existing slab before any mezzanine design is committed to.

Racking-Ready Floors: The Tolerance Issue

Narrow-aisle racking and automated storage systems require floor flatness tolerances that most warehouse floors do not meet as-built. The FM2 tolerance required by most racking suppliers (±3mm over 3m) is significantly tighter than the TR34 standard for general industrial floors. TCM works with specialist floor grinding and levelling contractors to achieve the required tolerances, and coordinates with racking installers to confirm acceptance before racking goes in.

Temperature-Controlled Storage

Cold stores, chilled rooms, and temperature-controlled picking areas require specialist insulated panel systems, refrigeration plant, and humidity control. TCM coordinates cold store fit-outs with specialist refrigeration contractors, managing the building envelope, M&E interfaces, and building control submissions. We have delivered temperature-controlled storage facilities from 2°C to 25°C across Hertfordshire and North London.

Hazardous Materials Storage

COSHH-compliant storage areas for flammable liquids, chemicals, and other hazardous materials require specific construction standards — fire-rated construction, spill containment, ventilation, and specialist electrical installations (ATEX-rated equipment in Zone 1 and Zone 2 areas). TCM designs and builds hazardous materials stores to the requirements of HSE guidance and your insurer's requirements.

Industrial Fit-Out FAQs

In most cases, no. A mezzanine floor installed within an existing industrial building is generally permitted development under Class PA of the GPDO, provided it does not increase the gross floor area of the building by more than 25% or 1,000 sq m (whichever is the lesser). However, if the building is in a conservation area, is listed, or if the mezzanine changes the use of the building, planning permission may be required. TCM checks the planning position on every project before any design work is committed to.
