Bespoke Garden Offices

Garden office prices

At Rubicon, our premium garden offices start at £17,250, with no hidden fees. However, garden office models can vary in price depending on several factors.

The total cost to install an office garden room will be determined by the desired size, specifications, and overall quality of materials, as well as the location of your property.

After all, if you’re investing in a garden office, you’ll likely want it to be designed as if it were made just for you. To do this, you’ll require access to a wide range of features and specifications, which can affect the price.

If you’re looking for something truly unique, this is something we accommodate here at Rubicon. As no bespoke project is the same, we will provide you with a quote based on your desired finish.

You’ll find pricing information attached to every garden office model on our website. However, for more on our garden office pricing, click here to get in touch.

Saving money with a garden office

The initial cost of an office garden room can seem daunting at first. However, consider how this investment will save you money in the long run.

Gone are the days of commuting to work costs, and if you’re a business owner, you’ll know how expensive office rentals can be. When you invest in a garden office, you won’t have to worry about either of these financial burdens anymore.

Plus, with a garden office, you’ll benefit from a better work-life balance. When you’re finished with your working day, you won’t need to worry about how long it takes you to get home - as you’re already there! Allowing you to spend more of your downtime on enjoyment.

A garden office is the most cost-effective way to create additional living space. A garden office will cost a fraction of a home extension project, adding significant value to your property.

Factors that affect the overall cost of a garden office

When it comes to purchasing a garden room, there are several variables to consider. See below for the main factors that can affect the overall cost of an office garden room.

Size and structure

The overall size and structure of a garden office can affect the cost. We recommend determining the amount of living space required for the comfortable use of your office space so that you can narrow your search.

At Rubicon Garden Rooms, we offer an extensive selection of garden office sizes, types and designs. We cater to all preferences and include all of our sizing information on each model, with detailed specifications on the interior and exterior sizing. To check out our range of garden offices, click here.


Where your property is located can affect the overall cost of your garden office installation.

Generally speaking, if you’re based far away from your garden office provider, you can be charged the additional travel costs for the team to complete the installation. We advise asking your provider regarding travel costs before committing to a purchase to avoid hidden fees.

At Rubicon, we can travel up to 70 miles from our Deeside headquarters without any additional charges. If you’re uncertain about any travel costs associated with our services, click here to contact us directly for a no-obligation chat!

Installation fees

Generally speaking, providers may charge an additional fee to install your new garden office, and sometimes even charge per installation project. For example, some providers charge separately for interior installation projects, such as flooring.

At Rubicon, our pricing includes the installation fee, so there will be no hidden fees with our premium garden office extensions.

Additional features

Even our most cost-effective garden office options include many worthwhile features, which are included within the cost. However, if you would like to customise your office space, there may be additional charges.

Take our functional Cabin Style garden office as a superb example. Our smallest standard option is sized at 3.5M X 3M (although bespoke sizes are also available) and offers a wide range of structural and decorative benefits included in the cost. This includes (but is not limited to):

  • Insulation - fully insulated for comfortable all-year-round use.
  • Walls - ventilated cavity walls made from premium Zero Maintenance Wood Fibre Cladding.
  • Timber framing - 20yr treated C16 (or C24) structural grade timber frames for exceptional, long-lasting quality.
  • Finishes - plasterboard will be applied to the interior walls for a homely finish, lighting fixtures, and quality UPVC skirting boards will also be installed.
  • Roofing - PIR foam insulation, with a plaster, skim interior finish and UPVC facias around the perimeter.
  • Floors - insulated floor installation, fitted with treated C24 floor joists and completed with a damp control membrane and under-boarded for rodent protection.
