Oilcanfinish are bespoke summerhouse builders. Our structures designed to your specification, using your choice of materials, and are far stronger than off the shelf sheds from DIY stores and Garden Centres. The key to the buildings strength is the framing materials used for the base, walls, and roof structure which need to be wide enough to allow insulation to be installed, electrical wiring to be hidden, and still provide vacant air cavities to prevent moisture damage between the outer cladding and interior finished wall. Timber framed houses and buildings are very popular in Canada, where we are from, and are subject to extreme weather conditions. Most over the counter, pre-packaged sheds have very thin support structures and framing supports preventing the owner from enhancing the shed with internal finished plasterboard walls, double-glazed windows, fully sealed roofs, and UPVC Doors. 

To prepare the area we can pour concrete pads for sheds if needed, or suspend the frame above ground, to ensure your shed floor is protected from rot, wood boring insects, and moisture damage.

All Garden Sheds and Summerhouses can be Sealed, Stained, or Painted to enhance the sheds longevity and protect your investment.

Our bespoke sheds are built to last using strong, sturdy pressure treated framing which is wide enough to add both insulation, wiring, lighting, and finished interior surfaces as well as flooring as well as being strong enough to support wall mounted objects such as bike storage or televisions.

Doors and Windows

Our heavy duty Summerhouse floors and wall frames are strong enough to accommodate standard size and weight doors as you would have in your house.


There are numerous options to clad your Summerhouse in style. Cladding options vary in appearance, maintenance, and longevity. A few our favorites are:

Canadian Western Red Cedar Cladding
Iro Timber Cladding
Shiplap Cladding
Composite Cladding

Soffits & Fascia

Soffits and Fascia are the finishing touches which not only provide a superior, polished look to your Summerhouse, but also increase it’s ability to withstand british weather conditions.

We recommend UPVC Soffits and Fascia, however in certain situations, where a particularly attractive species of wood is used in the cladding, it is best to match the Soffits with the Cladding.

Summerhouse Planning Permission & Permitted Development

Before designing and installing your summerhouse, bear in mind your Garden Summerhouse is considered Permitted Development subject to the following limitations:

  • Outbuildings and garages to be single storey with maximum eaves height of 2.5 metres and maximum overall height of four metres with a dual pitched roof or three metres for any other roof.
  • Maximum height of 2.5 metres in the case of a building, enclosure or container within two metres of a boundary of the curtilage of the dwellinghouse.
  • No more than half the area of land around the “original house”* would be covered by additions or other buildings.
  • No part of the shed / greenhouse / building is in front of the principal or side elevation of the original house that faces onto a road.

Summerhouse Building Regulations

When designing and installing your summerhouse, please note the total size in Square Meters of your Summerhouse is addressed by Building Regulations.

  • If you want to put up small detached buildings such as a garden shed or summerhouse in your garden, building regulations will not normally apply if the floor area of the building is less than 15 square metres and contains NO sleeping accommodation.
  • If the floor area of the building is between 15 square metres and 30 square metres, you will not normally be required to apply for building regulations approval providing that the building contains NO sleeping accommodation and is either at least one metre from any boundary or it is constructed substantially of non-combustible materials.

Please note although they do not change frequently, Permitted Development and Building Regulations can change on occasion. There may be additional restrictions if your house is a Listed Building or you live in a National Park, Area of Outstanding Natural Beauty, or World Heritage Site.
