Specification guides for Cat A, Cat B, and Cat A+ fitout, helping landlords, tenants, and project teams make informed decisions.

Guide

Understand
Fitout

A fitout is the design, construction, and installation of interior elements tailored to the occupant or tenant, from partitioning and MEP to furniture and technology.

GOS fitout design guide with blueprints and material samples

Core fitout activities include:

Partitioning

Creating divisions within the space using walls, glass partitions, or other structures.

Flooring

Installing the appropriate flooring materials, such as carpets, tiles, or hardwood.

Ceiling

Setting up the ceiling structure and installing ceiling tiles, gypsum board, or other finishes.

Lighting

Installing lighting fixtures and systems to illuminate the space appropriately.

MEP Work

Setting up electrical systems, outlets, and required wiring. Installing heating, ventilation, and air conditioning systems to regulate the temperature.

Decoration

Applying finishes, colours, and decorative elements to enhance the overall appearance.

Furniture

Adding furniture and fittings aligned to functional and aesthetic requirements.

IT Infrastructure

Installing essential technology and communication systems.

Specification

Three completion levels define how far a commercial space is finished before occupation. Compare each category against your landlord agreement and business readiness.

01Landlord Shell

Cat A Fitout

Category A is the landlord's foundational finish, a serviced blank canvas with essential MEP, lighting, floors, and walls in place. Furniture and branding remain the tenant's scope.

A Cat A office fitout typically includes:

  • Raised access floors.
  • Suspended ceilings.
  • Essential electrical services (lighting, power).
  • Basic mechanical services (air conditioning, ventilation).
  • Fire detection and protection services compliant with building regulations (smoke detectors, fire alarms), and internal surface finishes meeting industrial standards.
  • Additionally, common areas such as toilets, showers, lifts, lobbies, and breakout areas may be refurbished, unless already addressed in the Shell and Core fitout.
02Move-In Ready

Cat B Fitout

Category B delivers a move-in-ready workspace, with partitions, furniture, kitchens, IT, and brand detailing completed in close collaboration with your design team.

A Cat B layout will typically include the following:

  • Air conditioning, heating, and power points
  • Fully fitted kitchens and non-communal office amenities
  • Partitioning that includes meeting rooms, offices, break-out spaces, and reception area.
  • Office furniture such as desks, workstations, chairs, and meeting booths, all fully fitted.
  • IT installation and infrastructure
  • Design and brand detailing
03Flexible Occupancy

Cat A+ Fitout

Category A+ bridges shell and full fitout. Occupancy-ready with furniture, partitioning, and services, it suits landlords and co-working operators who need flexibility without a full Cat B commitment.

A Cat A+ office fitout will typically include:

  • Furniture and workspaces
  • Partitioning including meeting rooms, offices, and breakout spaces
  • Kitchens and toilets already fitted.
  • IT installation and infrastructure
  • Air conditioning and required power points.
