A blend of contemporary and traditional, the Holkham Summerhouse has an urban feel that can help accessorise an outdoor look so well.
With a pitched roof and clean lines, The Holkham gives a modern twist on a classical range: it has plenty of glazing for a light and airy feel, which complements the design, and each building is finished to our exceptional standards.
To create your own ideal Holkham Summerhouse, please click on the Create My Summerhouse tab below.
Our Holkham Summerhouses are available in a range of sizes.
From 1.8 x 2.4m (6 x 8ft) to 4.8 x 6.0m (16 x 20ft) and plenty of sizes in between.
Window Styles & Options
To afford a light and airy feel inside your Holkham, there are windows in 3 of the 4 sides, as well as in the double doors.
The windows are all made from 4mm toughened safety glass, and are finished with polished brass or chrome furniture. You can also choose to have double glazing to help create a warmer, year-round use building.
You can choose from plain, leaded or Georgian-style windows.
Our Holkham Summerhouses come with your choice of roof covering: our heavy duty, torched-on felt is the standard material, but you can also choose either Cedar Shingle Tiles, or Slate Effect Tiles in terracotta or grey for more of a stylish effect.
The cedar and slate effect tiles add longevity to your garden building, they don't require much maintenance, and they are attractive and sit harmoniously in outdoor settings
Our Blakeney, Morston and Holkham Summerhouses come treated with light oak wood preservative as standard, which protects the timber from fungi and woodworm and gives the timber a natural looking sheen. We also offer two paint ranges to choose from: these are Valtti and Farrow & Ball to give the best possible paint options for your building.
- High quality exterior paint.
- Weather resistant and protective.
- Fully opaque four coat system.
- Inspired by nature and the soft neutral tones of traditional colonial buildings.
Farrow & Ball
- High quality exterior paint.
- Water resistant and anti-fungal.
- Rich, fully opaque colour.
- Specially selected colours from the Farrow & Ball paint collection.
Our timber cladding is machined from very high quality Redwood grown in Northern Sweden, close to the Arctic Circle.
Due to the low temperature in this part of the world, these slowly grown trees produce a much more dense and stable timber than others. The timber mill we partner with, and have very close links to, is FSC® certified like ourselves.
We machine our cladding into particularly thick boards, and because it's a slowly grown timber with an exceptionally close grain, the additional benefits of our cladding are its strength and durability. We machine a capillary groove into our shiplap to reduce the risk of water ingress; and also give our shiplap rounded edges so that paints and stains grab and adhere with maximum effectiveness and coverage.
We clad your building in shiplap as standard, but we also offer weatherboard cladding for a more rustic finish.
Lining & Insulation
The Holkham Summerhouse comes unlined as standard for purely summer use, but you can also choose to have lining and insulation in the walls and ceiling. This makes it a perfect all-season retreat and greatly enhances the finished look of the building, increasing comfort and decreasing noise levels.
You can also choose to have the floor insulated as well, as an extra option.
For the roof we have a 4 tier lining and insulation process; we insulate between the ply layer and the internal matchboard tongue and groove lining and finish the building with your choice of roofing material. For the walls, we insulate your building by trapping a breathable paper membrane between the studwork, which acts as a moisture trap before filling in with insulation.
There are then 2 options for lining your Summerhouse: natural matchboarding, or painted matchboarding. To have it painted, you can choose our own Ivory internal paint colour, or choose between 5 Farrow & Ball paint colours.
When choosing the internal options for your new Summerhouse, you have the following flooring options:
Our standard (ex 19mm thick) and robust floorboards are set on closely spaced tanalised floor joists, but we can also offer heavy duty (ex 38mm thick) flooring if you are planning on storing particularly heavy items or if there's going to be a lot of movement inside your new Garden Building.
The lacquer is applied to the floorboards in either Natural or Light Oak to help protect the timber, as well as giving it a nice sheen.
This option can be chosen as an alternative to a lacquered floor. There are four different colours to choose from, and the engineered flooring offers a chance to further personalise your new garden building, whether you’re aiming for a traditional, rustic or contemporary style.
Our engineered floorboards sit on top of the existing floorboards, with a layer of underlay in between the two, providing further insulating and sound absorbing benefits.
For lighting and power in your building, you will get an electric pack with the option of adding a heater to enable you to use it all year-round.
Professionally fitted by qualified electricians who take all the wiring to a consumer unit ready for you to connect to your electricity supply. Internal wiring will be fitted behind the internal lining.
Please see the specification tab to see what is included in the electric pack.
To add extra versatility to your Summerhouse, we also offer the option of adding partitions. You can have an external partition, which is generally used to add a storage section, or you can have an internal partition or partitions, to allow you to add extra rooms, such as a toilet, or internal storage space that can be accessed inside, without having to go outside.
Guttering collects the water run-off from the roof and then deposits the water away from the building. This stops the bottom boards rotting prematurely, adding an even longer life to your building. Guttering is available in black or white.
We add the guttering and downpipe along the lowest side/eave of the roof. The addition of guttering also allows you to install a water butt.
All our buildings require a level, solid concrete base of the correct size.
The single most important part of installing a garden building is the base. Bases must be:
- Of the correct size
- Square i.e. have right angled corners
A concrete base supports your building in the best possible way, adding longevity, as well as creating a substantial distance between your building and surface water.
We can supply a 100mm deep reinforced concrete base ready for your building, laid by our professionals, in advance of your building being installed by us. The site must be clear and reasonably level for us to do this.
The base should always be a minimum of 50mm out of the ground to prevent surface water or puddles affecting your building i.e. rotting it.
The base you have must be made to the plans we give you when you order your building, whether we install the base, or you get a trusted builder to do it for you.
Bases for larger buildings, and in particular garages, need to be built to exact dimensions - we create special base drawings for our garages, since they sit directly on the concrete base and must be anchored into place.
Always get your garden building base laid by a professional, whether that is us, or a local builder you trust.
We constantly strive to ensure all our materials and techniques are the best that we can source and provide. We lead the market in producing exceptional quality timber buildings. Couple this with our personal and bespoke service and you will be totally delighted with your building.
