Custom Modular Office Solutions: What Are Your Options?

Need more workspace without the cost and disruption of a permanent build? Custom modular office solutions could be the answer. Whether you’re managing a construction site, growing your business, or adding extra workspace at a school or factory, modular offices provide flexibility, speed, and customisation. 

In this guide, we’ll explore the different office options available, from portable cabins to shipping container offices, so you can find the best fit for your business. 


What Is a Modular Office? 

A modular office is a prefabricated building that’s manufactured off-site and assembled where you need it. It can be permanent or temporary, custom-built or ready-to-go. These buildings are popular because they’re fast to install, cost-effective, and flexible in design. 

You might also hear them called: 

Whatever the name, they serve the same purpose: a smart, efficient workspace without the construction headaches. 


Portable cabins for Sale: A Flexible Office Option 

One of the most popular modular office solutions is the portable cabin. These portable cabin units are ideal for site offices, remote teams, or businesses in need of a fast office set-up. 

Benefits: 

  • Quick to install and move 
  • Can be hired or purchased 
  • Range of sizes and internal layouts 
  • Insulated and ready for electricity, heating, and plumbing 

If you’re looking for a cabin for sale, we offer a wide selection of units that can be tailored to your requirements. 


Shipping Container Offices: Strong and Secure 

Looking for a more industrial or urban-style workspace? A shipping container office is a robust, modern solution that’s becoming increasingly popular in the UK. 

Features of Office Containers: 

  • Built from durable steel containers 
  • Can be fully insulated and weatherproofed 
  • Stackable and customisable 
  • Ideal for construction, logistics, and events 

We specialise in bespoke shipping container conversions, turning containers into high-quality workspaces that look and feel like traditional offices. 

Modular Buildings for Larger Office Needs 

When you need more than just a single unit, modular buildings provide a multi-room or even multi-storey solution. These are ideal for schools, NHS sites, corporate expansions, and commercial use. 

Custom Modular Buildings Can Include: 

  • Reception areas 
  • Meeting rooms 
  • Open-plan offices 
  • Kitchens and WC facilities 
  • Heating, lighting, and IT infrastructure 

If you’re planning long-term growth, a modular office building gives you the space without the delays and costs of traditional construction.

  • Bespoke shipping container conversions

Examples of Our Work 

Birmingham City FC – Bespoke Portable Cabin with Pitch Views 
We supplied a 40ft x 12ft portable cabin to Birmingham City FC, fully converted with a complete glass frontage overlooking the first team training field. The unit was fitted with electric sockets, LED spot lighting, air conditioning, and, of course, a blue carpet to match the club colours. 

Bespoke Portable Cabin

Air Ambulance – Cabin for Helicopter Parts and Engineering Support 
The Air Ambulance team, required a high-quality cabin to store helicopter parts and provide a warm, comfortable workspace for their engineers. (The helicopter was out saving lives during installation!) 

Cabin for Helicopter Parts and Engineering Support

Cove Holiday Park – Rooftop Bar from Portable Cabins 
At Cove Holiday Park, we transformed multiple portable cabins into a stunning rooftop bar and communal space, valued at around £80,000. This project shows how portable buildings can be customised into unique, functional spaces that go far beyond traditional uses.
