How to Add a Garden Office

How to Add a Garden Office

An increasing number of people are choosing to work from home, but hate having their home office on top of them all the time. Mark Ramuz reports on an easy and popular alternative, the garden office

Over two million of us work from home and that figure looks set to grow as more people swap office life for home working. However, the convenience of teleworking comes with its own drawbacks, in particular the loss of a room in the house and the feeling of never really ‘leaving work’.

This is why many people are now creating dedicated work spaces in their gardens, away from home life and all of its distractions. Whether you fancy a big DIY project, or will find a specialist company to take on the work, we look at what to consider when building a garden office.

How Big Can a Garden Office Be?

There’s no hard and fast rule on the optimum size, but a garden building should never look overbearing or take up more than half of your garden. However, if you plan to build it without planning permission you will be restricted to:

  • an eaves height of 2.5m,
  • an overall height of 3m (or 2.5m if within 2m of a boundary)

Where you plan to site the new building is also important. If it will be within five metres of your home (and over 10m²) it will be treated as an extension to your house. Your local authority will then count it as part of your permissible development. This may be a problem if you already have a large extension to your home. It also cannot sit forward of the principal elevation of the original property.

Design Practicalities

At the planning stage, consider creating a hard path leading to its entrance so you don’t churn up the grass. Trees or shrubs screening the building will make it less conspicuous, and maintain privacy for you and any neighbouring properties.

In addition, your neighbours may object if the room blocks light to their property or overlooks them. Always contact your local authority planning department and ask their advice. You may be asked to send in a sketch with the dimensions and location in your garden. Your council office’s planning department should let you know within two weeks if it needs planning permission.

Building Regulations don’t apply to the building of a timber cabin as it is classed as a ‘temporary structure’.

If you have a large garden, aim to get your new building to face south. You can even add roof windows, as well as a sink, toilet or work surfaces.

How to Secure a Garden Office

Bear in mind that a garden room is often an easier target for an intruder than a house. Police initiative Secured by Design offers tips on keeping your property safe.

  • Fit a PIR light and alarm to sense movement.
  • Buy metal security casings for PCs and lock these to the walls.
  • A gravel path to the building can act as a deterrent to intruders.
  • Ensure all doors and windows have locks that meet your insurer’s standards (BS 3621 is usually cited).

Choosing a Garden Building

Timber clad buildings are a popular choice as they can match both traditional and contemporary properties. For a low maintenance option, choose thermally-modified timber — it will cost more initially, but the alternative if treating the cladding with preservative every two to three years.

Brick and block requires very little maintenance, but will add to the cost of the project. As will the inclusion of a lot of glazing.

Alternatively, you could look at the many unusual buildings such as shepherds’ huts, tabernacles and modified gypsy caravans that can be quickly installed as garden offices.

To meet planning requirements (or not need planning as the case may be), find a garden room which meets the permitted development criteria listed above.

How Much Does a Garden Office Cost?

Size, construction type and whether you take the DIY approach will all have an impact on the overall cost of your garden office. A DIY kit can cost as little as £1,000 for a 3x3m, uninsulated cabin. Bespoke options can cost as much as £30,000 for a fully-insulated, glazed, wired, heated and finished option.

As a guide:

  • Cabin Style: Softwood tongue-and-groove boards interlock at the corners to form a cabin with a pitched roof. You only need a few metal fixings for the roof and floors and the rest locks together and can be built up in a couple of days. B&Q’s range starts from around £1,600. The glazing is plastic but you could fit your own double glazed units. A 3x3m cabin from Garden Affairs in 44mm timber and a range of door/window styles starts from £3,815.
  • Modular: Basically mini houses, with softwood clad walls filled with insulation and plasterboard interiors. These buildings can also be assembled quickly. Doors and windows are often Pilkington K double glazed units. The Garden Escape can supply anything from a 7.2 to a 19.8m² unit with insulation, electrics and phone points installed from £7,500.
  • Timber Frame: If your wallet stretches to £10,000+ a timber framed building is the ultimate hideaway. Choose weatherboarded or rendered panels, an oak frame, roof tiles or even a thatch roof. Courtyard Designs offer 10x15ft–20x15ft offices with a double glazing, high security locks, wiring, lighting and insulation from around £21,000–£28,000.

How to Heat and Insulate Your Garden Office?

A cold and draughty garden office is not going to be an appealing place to work, so when it comes to insulation, treat it like a habitable space. Basic versions, or glorified sheds, will need added insulation, but most garden offices on the market are either modulate or closed-panel builds with insulation already incorporated.

You will also want to choose double glazing and a well-insulated door to keep a comfortable temperature year-round.

Electric radiators or electric underfloor heating are practical as your office will need to be connected to main electricity anyway. However, heating with electricity can be expensive so consider adding a woodburning stove instead, and focus on good insulation. It might also be worth considering renewables.

What is a garden office?

A garden office is an office in a garden. This is usually separate to a house, being used as a dedicated office space by a professional homeworker or by a home-based business. In the UK, planning permission is not normally needed for a garden office if you are only using it as a home study and if it is similar in size and construction to a garden shed. A garden office used as a home study does not need planning permission as long as it is not more than 4 metres tall for a pitched roof, at least 2 metres from the property line and does not cover more than half of the garden area. If you are running a business from your garden office it will need planning permission regardless of its size or position within the garden. This is because working at home, in the garden, can cause a problem for neighbours. The cost will depend upon the facilities and will be between £5,000 and £60,000. Internet and telephone connections may be required and this can perhaps be achieved by use of a wireless network based in the main building.
