rain gutter

Guttering & water butts

Your new timber building will help you enjoy your garden regardless of the British weather, but when it's raining where will all the water go?

All our buildings have roof designs with sufficient overlap to direct rainwater away from your building, but you may want to add gutters to your building to control where your water goes or even just to store it up for use when watering your garden.

Depending on the type of roof you choose you may need guttering all round your building or just to a single side. A pent roof systems sloping to the back of your building would allow gutters to be concealed at the rear of your building, with plenty of room to accommodate water butts.

Most of us pay for our water on a meter so it makes sense to harvest any 'free' water available to use on our gardens. If this option is something you would like for your building, please mention it when you talk to us and we can discuss your options.

Ground preparation

Ground preparation

All our buildings require a solid level base, to ensure that your finished building is both properly supported and elevated to provide the protection from the weather at the ground where it is needed most.

If this is something you already have or are happy to prepare yourself we can offer advice on what would be required. (You can see some examples of ground prepared in the gallery below.)

Some customers prefer for us to prepare the base as part of their project which we are also happy to do.


If you are wanting to connect your garden room to your homes electricity, water or broadband utilities it may be worth digging a trench for cables and pipes at the same time as preparing your base.

sikkens preservative

External finish

Protecting your building is the secret to a long life for anything constructed of wood. All our timber buildings come complete with a finish of either a shed manufacturers preservative, cuprinol high grade preservative or cuprinol shades range - (option includes nail fills). We can even match your finish to existing buildings in your garden.

Paint finishes

We finish our external timber with Cuprinol Decorative or Cuprinol Shades in a range of attractive fade resistant finishes, it has excellent all weather protection and is harmless to both pets and plant life. We can use alternative finishes upon request.

In order to get the best possible appearance for your garden building, we will even recess and fill any screw or nail heads on any facing sides of the building prior to painting. If you want us to do this on all sides of the building or to non painted buildings just let us know when ordering your building.

Natural finishes

Enjoy the natural appearance of your timber building by opting for a more natural finish. All our buildings come finished in either a proprietary wood preservative or with cuprinol high grade preservative, which is a standard finish on our garden rooms, summerhouses and home offices.

We also offer our customers the option to specify their own finish, which we will apply during the manufacturing process. We have had excellent results using the 'Sikkens' range of preservatives however their is an additional cost to both the material and the time it takes to apply Sikkens.

electric and water connection

Power, water or internet

If you are planning to have electricity, internet or even a water supply to your building it's worth planning for this early on in your build when you are preparing your base.

The simplest solution is to dig a trench between your home and your garden room, the width only needs to be sufficient to lay any pipes or cables however the depth need to be at least 50cm for your armoured electricity supply, and you may want to lay your water supply up to 75cm deep to avoid freezing.

Apex are happy to do this work as part of your project, and any work that requires certification will be carried out by a fully qualified professional.

Electrical installation

We use qualified engineers for all our electrical installations.

When considering powering your shed or garden building you need to think about what are you are planning to use it for and what electrical equipment you are going to use:

  • Lighting
  • plug sockets
  • External sockets for garden equipment or lighting
  • Underfloor heating
  • Hot tubs
  • Alarm systems

Also do you plan to line your building? if not you will need conduit or trunking to secure your wiring to the inside of your building.

We are happy to provide advice on any aspects of powering your garden building.


Whether you want to use your garden building as a home office, a place to relax, play computer games or read your ebook you'll need access to your home internet connection.

Depending on where your home internet connection is you might be able to access wireless internet from your garden building, although it's worth thinking about the following:

  • Some types of insulation can effect your wireless signal, particularly the types that use a metallic surface.
  • You might consider using mains networking, which provides an internet connection through your mains sockets. This option obviously depends on whether you plan to have electricity installed in your garden building. Whilst we have had success with this option it is not a guaranteed solution as outside buildings are often wired with their own consumer unit.
  • A wired connection has been the most effective solution in our experience, and if you are planning to connect your home office to your home's mains supply it makes sense to include a cable for connecting your home broadband connection at the same time.

Water supply

There are many reasons why a water supply might be useful in your garden building whether to water your plants, wash your hands or even make a cup of tea.

The main concerns in running a water supply from your home to your timber building, is freezing and contamination, both can easily be avoided by making sure your pipe work is suitable for purpose. If you run your pipework under ground you should look to be about 75cm below ground level which will reduce the risk of freezing and give yourself adequate depth to add some back fill whilst maintaining the 50cm depth required for armoured electrical cable.

Lining your timber building

Lining your building gives your building a more finished appearance as well as hiding any insulation or wiring you may have chosen to install. The type of lining you choose depends on it's use or how you want it to appear.

6mm WBP Ply board

T&G boards

Kiln dried tongue and groove boarding provides a highly attractive finish for the inside of a summerhouse, garden room or home office. extending the beauty of your timber building to the inside. t&g boards can be left natural, stained or painted to suit your individual taste.
