Modular Office Sizes and Layouts

Working out the right modular office size starts with understanding how the space will actually be used. Flex Modular Buildings can talk through the number of employees, workstation sizes, private offices, meeting rooms, reception areas, kitchens and welfare facilities, toilets and storage you need, alongside the available footprint on site.

From there, we can recommend a practical building size and layout based on your day-to-day requirements, rather than simply quoting for a standard unit. Future growth can also be factored in, helping you avoid choosing a building that feels cramped from day one or provides more space than you realistically need.

Our Modular Office Process

Step 1: Tell Us What You Need

It starts with a discovery call to understand exactly what you need from your modular building. We’ll discuss its intended use, preferred size and layout, your budget and when you’d like it delivered.

Step 2: Choose Your Size & Layout

Based on your requirements, we’ll recommend the best size and layout for your modular office building. We can then start to tailor the design with your preferred doors, windows and other key features, creating an office that’s custom built to you.

Step 3: Review Your Drawing and Quote

We’ll provide a free 2D layout drawing and a clear, competitive quotation, with our team responding quickly once your initial requirements have been discussed.

Step 4: Site Survey and Project Planning

We assess your site where your modular office will be in situ before installation takes place. We will perform an initial desktop survey, as well as perform a site visit to assess crane access, transport and groundworks. Planning ahead of time only helps to make the project more efficient and less disruptive for your business.

Step 5: We Manufacture Your Office

Once your design is approved for production, we get to work manufacturing your modular office building at our UK-based facilities, with all work backed by official certification and a 20-year structural warranty for your peace of mind. 

Step 6: Delivery to Your Site

We arrange delivery on a time and date that meets with your convenience, no matter where it is in the UK.

Why Choose Flex Modular Buildings?

Why choose Flex Modular Buildings? We provide bespoke, made-to-order modular offices built around the way your business actually needs to use the space. From our initial consultation, we take the time to understand your team, layout requirements, available footprint and future plans before recommending the most suitable options. 

You will have a single point of contact throughout the project, with responsive quotations and free drawings to help you visualise the proposed layout before moving ahead. Buildings are manufactured in the UK, with nationwide delivery and installation available, and are supported by a 20-year structural warranty. 

Finance and payment options may also be available depending on the project, giving businesses more flexibility when planning a new modular office.

FAQs

What is a modular office building?

A modular office is made from prefabricated sections that are manufactured before being delivered to site and assembled into the finished building. The layout can be planned around workspaces, meeting rooms, welfare facilities, storage and other practical requirements.

How much does a modular office building cost?

The cost of a modular office building can vary depending on its size, layout, specification, facilities and site requirements. Flex Modular Buildings can prepare a quotation once the project requirements and proposed building have been established. 

How long does a modular office building take to install?

Installation times vary according to the size and complexity of the modular office, as well as site access and any associated groundworks. A project-specific programme can be established once the building and site requirements are understood. In many cases, modular office buildings can be installed and be ready for use within a few days.

Do modular office buildings need planning permission?

Planning permission requirements can vary depending on the building, its intended use and where it will be installed. See our planning permission guidance for more information, or call us to discuss your plans and we’ll advise on whether planning permission will be required for your modular office buildings. 

Do modular offices meet Building Regulations?

Building Regulations requirements can depend on the design, intended use and specification of the modular office. The relevant requirements will be considered as part of the project before the final specification is agreed.

Can modular offices be customised?

Yes. Flex Modular Buildings offers made-to-order modular offices with options including different colours, door and window positions, internal layouts and power point locations. Heating and cooling arrangements will be confirmed as part of your building specification.

Can modular offices be double storey?

Yes. Modular offices can be double-storey structures. We can manufacture single, double and triple-storey designs, with expansion and reduction on size easily accommodated if required.

What size modular office do I need?

The right size depends on more than employee numbers. We consider important details like workstations, offices, meeting rooms, welfare facilities, storage, available site space and future requirements before recommending a suitable size and layout.

Are modular offices suitable for permanent use?

Yes. While they can be for temporary use, modular office buildings are ideal for gaining cost-effective, permanent structures for your business. Each of our modular offices comes with a 20-year structural warranty. If you are considering a more temporary solution, our portable cabins may be the better choice.

Do you install modular offices nationwide?

Flex Modular Buildings works with customers nationwide. Installation arrangements can be discussed as part of the quotation once the building specification and site requirements are known.
