Discuss Your Project
The Preform Process

A considered process from brief to completed building.

Every Preform project begins with an understanding of the building's purpose, site and required specification. From there, the design is developed, manufactured in controlled conditions and prepared for delivery and installation.

01
Project Brief

Understand the requirement

We review your proposed use, preferred dimensions, site conditions, accommodation needs, appearance and required performance.

02
Design Development

Configure the building

The layout, structure, openings, internal arrangement and external finishes are developed around the project brief.

03
Controlled Production

Manufacture with precision

Building components are produced in controlled factory conditions to support consistency, coordination and efficient quality management.

04
Delivery and Assembly

Complete the project

The prepared building system is delivered to site for coordinated assembly, installation and completion in line with the agreed project scope.

Every project is different. The exact design, manufacturing, delivery and installation process will depend on the building specification, site and services required.

Why Choose Preform

A building system designed for greater flexibility.

Preform combines adaptable design with controlled manufacturing to create buildings that can respond to different sites, uses and architectural requirements. Each project can be configured around the space, appearance and level of specification required.

Discuss Your Requirements
01

Configurable design

Dimensions, layouts, openings and internal arrangements can be developed around the intended use of the building rather than forcing the project into a fixed standard format.

02

Controlled manufacturing

Components are prepared in controlled production conditions, supporting coordinated construction, consistent detailing and efficient quality management before delivery to site.

03

Architectural choice

A range of external finishes, colours, window positions and architectural details can be considered to create a building that suits its setting and reflects the intended appearance.

04

Coordinated delivery

Design, manufacture and site delivery are considered as part of one coordinated process, helping each stage of the project progress in line with the agreed building scope.

05

Multiple applications

The system can be considered for commercial, industrial, educational, healthcare, specialist and residential buildings with different spatial and operational requirements.

Project-led Designed around the brief
Adaptable Flexible layouts and finishes
Coordinated From design through to site
Specification and Customisation

Configured around the way your building needs to work.

A Preform building can be developed around the intended use, architectural appearance and required internal environment. The final specification is considered as part of the complete project rather than treated as a collection of standard additions.

01

Exterior appearance

Create an exterior that responds to the building's setting, purpose and preferred architectural character.

  • External cladding options
  • Colour and finish selection
  • Window and door positioning
  • Roofline and elevation detailing
  • Entrance and façade features
02

Internal configuration

Develop a practical internal arrangement around occupancy, workflow, equipment and everyday use.

  • Flexible room layouts
  • Partition and circulation planning
  • Kitchen and welfare facilities
  • Storage and operational areas
  • Interior finish selections
03

Technical performance

Consider the building fabric and services in relation to comfort, operation and project-specific requirements.

  • Insulation and thermal requirements
  • Heating and ventilation options
  • Electrical and lighting provisions
  • Plumbing and service coordination
  • Accessibility considerations
Project-Led Configuration

One coordinated specification, developed around your brief.

Available options will depend on the building type, site, intended use and agreed project scope. Requirements can be discussed during the early design stages.

Layout Space planned around use

Room sizes, circulation and operational areas can be considered against the project brief.

Finishes A considered visual identity

Exterior and interior finishes can be selected to suit the building's location and purpose.

Services Coordinated building systems

Electrical, lighting, heating, ventilation and plumbing requirements can be reviewed together.

Performance Requirements considered early

Building fabric and technical requirements can be incorporated during design development.

01 What is a Preform building?

A Preform building is a prefabricated building solution developed around an agreed project brief. Its layout, appearance, internal arrangement and technical specification can be configured for commercial, specialist or residential use.

02 Are Preform buildings available in standard sizes?

Building dimensions are considered in relation to the intended use, site and chosen configuration. The team can discuss appropriate dimensions after reviewing your required accommodation, access and operational needs.

03 Can I customise the internal layout?

Internal layouts can be developed around the way the building needs to function. This may include rooms, circulation areas, offices, welfare spaces, kitchens, storage and areas for specialist equipment.

04 What exterior finishes are available?

External appearance can be considered during design development. Options may include different cladding materials, colours, window arrangements, entrance details and elevation treatments, depending on the building and project scope.

05 Do I need planning permission?

Planning requirements depend on the location, intended use, size and circumstances of the project. Appropriate advice should be obtained for the specific site before work proceeds.

06 How long does a Preform project take?

Timescales vary according to the size and complexity of the building, design development, approvals, manufacturing requirements, site readiness and installation scope. An indicative programme can be discussed once the project brief is understood.

07 What information is needed for an initial enquiry?

Helpful information includes the intended building use, approximate dimensions, preferred room layout, site location, required finishes, services and any known programme or access considerations.
