4mm Toughened Glass

Summerhouses 4mm Toughened Glass

4mm Toughened Glass
 
We use 4mm toughened glass in our windows and doors for increased safety and security. It's much better than 3mm horticultural glass, commonly found in garden buildings, as it's a lot harder to break, and if ever it is broken it breaks into small pieces rather than large shards. It is also much harder to scratch than the plastic alternatives, styrene, acrylic and perspex, so will preserve your clear view out for far longer.

We only use full lengths of timber in our buildings - we don't glue separate pieces together with finger joints. Not only are they stronger, but they look much better too.

Summerhouses Georgian Bars
 
Georgian Bars
 
Our windows and doors come with optional sculpted Georgian bars that sit firmly against the glass, rather than float in front of them. When applied to the windows and doors they add a traditional, elegant charm to your summerhouse. The Georgian bars are easily removed for maintenance, or if you decide you prefer the look of the building without them.

Slow Grown Spruce
 
Slow grown Spruce is used to make our summerhouse walls. This is because Spruce produces less sap than Pine and other redwoods, reducing any stains and damage to the furniture you place in your summerhouse.

The 15mm shiplap walls come in panels, so each piece of timber is cut to size. These panels are easy to slot in-between the solid 70mm corner posts, making the construction of your summerhouse quick and simple, almost like a giant jigsaw puzzle.

Avoid Planning Permission

Avoid Planning Permission
 
This building is under 2.5m high.
Why does this matter? Well, under permitted development rights buildings under 2.5m high can be placed as close as you want to a boundary (eg. a fence line) without planning permission. Buildings that are over 2.5m high, however, need to be placed over 2m away from any boundary
(eg. a fence line), which means that with taller buildings you end up with a lot of space behind them. If you want to find out more about permitted development rights see our planning guide

Pressure treated floor bearers

+
 
Pressure Treated Floor Bearers Valiant
 
Pressure treated floor bearers
 
By pressure treating our floor bearers we protect the lowest part of the building from rot and insect infestation. This forces the treatment deep into the timber using a large pressure treatment tank. Due to this costly but effective process we can offer our customers a genuine 10 year guarantee against rot and insect infestation on the bearers with no need for the customer to re-treat this timber at any point during that time.

Avoid Sagging Roof

Avoid Sagging Roof Valiant
 
Avoid sagging roof
 
Our summerhouses have robust 70mm x 35mm roof beams, which are reinforced by additional supports at the sides of each roof panel. With the metal spider brackets this gives a very strong roof structure to make sure that roof sagging is an issue that will only be suffered by the customers of companies that supply lesser products.

High Internal Eaves

High internal eaves
 
The high internal eaves (1.94m/6'4") give a spacious, light and airy feel once you're inside. This is the lowest point of the roof which quickly rises, giving plenty of headroom for all of you over 6'4"!

Internally Beaded Windows

Internally Beaded Windows
 
Both our doors and windows are fitted with internal beading used to secure the glazing in place. This beading style is typically found in uPVC windows and is a proven method of security. However, there are still some companies that externally bead their windows. Allowing intruders to remove the glazing from the outside of your garden house and gain access.

Have a question?


What is a Summerhouse?

+
A Summerhouse is a garden building made from pre-fabricated timber panels attached to a timber framework. Summerhouses also include several long windows, allowing large amounts of sunlight to fill the garden building.

How big is this Summerhouse?

+
This Summerhouse's measurements are: 3.58m (11' 8") x 2.43m (7' 11")

How high is this Summerhouse?

+
It is 2.43m (7' 11") high

How much is this Summerhouse?

+
This product starts from £ 2289.99

What foundation do I need for this Summerhouse?

+
We recommend a flat, level concrete base at least 100mm bigger on each side. e.g. A 4m by 3m building would have a base of 4.2m by 3.2m. See more details here.

What timber do you use in this Summerhouses?

+
We use slow-grown spruce timber for the main structure of the Summerhouse. Spruce is less porous than Pine and so less likely to shrink, warp or split.

What type of glass do you use in this Summerhouse?

+
We only use 4mm toughened glass in our Summerhouses which is a far more hard-wearing and resilient material than commonly used Perspex and styrene.

What is shiplap cladding?

+
Shiplap cladding is named after the old boatmaking technique with overlapping boards, which means that the natural timber can expand and contract with the seasons and not create gaps. The curve or channel of shiplap cladding enables water to run off easily, helping to protect your Summerhouse from the effects of damp.

Do you install?

+
Unfortunately, we do not offer installation currently. All our garden buildings have been designed on the basis that any competent DIY customer will have no problem installing a product themselves in a short amount of time.

You do not have to be an expert at DIY to build a Dunster House garden building, as we do provide you with comprehensive pictorial instructions. Also, if you prefer video tutorials, we do have a selection of videos on YouTube which will support you in building your product.

We totally understand that DIY is not for everyone and it can be very overwhelming to start building your own garden product. Therefore, you may want to consider getting in touch with a local carpenter or handyman to install it for you.

If you do take on the challenge to put your garden building together, we are always here to help. Do not hesitate to contact us at any stage of putting your product together and we can provide you with all the assistance you may need. Contact our customer service team via email at cs@dunsterhouse.co.uk.

Do I need planning permission?

+
Due to the unique design of a Dunster House product, in the vast majority of cases our garden buildings can be installed without the need for planning permission.

However, there are a few other factors to consider:

As all properties are different in size, shape and style we can only advise based on how we have designed our products, not on your property.

When to consider planning permission:

  • - If the garden building exceeds over 2.5m tall - the majority of Dunster House buildings do not exceed this.
  • - If you intend on putting an outbuilding in front of the main elevation of your property (as it was originally built or as it was on 1st July 1948) will require Planning Permission.
  • - If you live in a listed or graded building
  • - If you live in a designated area such as areas of outstanding natural beauty, national parks, world heritage sites and conservation areas.
  • - If there is a possibility that over 50% of your garden would be taken up by outbuildings.

Still not sure?

If you are still in doubt, we highly recommend getting in contact with your local authority before making a final purchase.

Our deliveries take place Monday to Friday between the hours of 8:00am and 6:00pm.


When the delivery vehicle is unloaded, it is important that you check to make sure all of the items and instructions have arrived and are correct.

If anything is missing or damaged, it is essential that you note this on your paper work when you hand it back to the delivery driver.


Prices for our delivery services can be found on individual products.


Please note that goods will be delivered to the first point of contact at the front of your property e.g. on your driveway. This must be within 20m from the delivery vehicle (Safely Parked at Kerbside). Our team will be responsible for assessing the risk of carrying out delivery upon arrival at the property.

Thank you for taking the time to read about our terms and advice during this period. We hope you can enjoy your Dunster House garden product for many years to come.

To ensure the very best quality, we only use slow-grown White Spruce Timber, which is harvested in cold climates to ensure solid, dense log rings. This gives the wood superior strength and longevity, and also a much more consistent colour than the likes of Pine.

 

Despite the care we take in selecting the very best Timber available, it’s not like predictable brick or cold steel, this natural material has characteristics and quirks unique to every log.

 

Because our timber logs once fed water and nutrients back and forth from its roots to its leaves, its very nature is to be porous and swell up when it gets wet. Any wooden product will do this throughout its life, but there are a few things you can do to help limit this movement.

 

These include:

1. A great design!

  • Don’t worry, we’ve got this one covered. We’re experts when it comes to all things timber, so we have designed our products from the ground up with its natural properties in mind.

2. Water Repellent Treatment.

  • How you customise and decorate your product is up to you, however we would recommend that you use an appropriate water repellent treatment. This really helps minimise the amount of moisture that the timber can absorb. Therefore minimising the risk of any major movement.
  • (Please note: water repellent treatment is not the same as pressure treatment, which protects against rot and insect infestation, and which we guarantee for 10 Years!)
  • On pressure-treated timbers, you may notice some subtle striation marks. These marks sometimes appear during the drying process of timbers. Fear not! In time, the marks will begin to fade as the sun starts to lighten the wood.

3. Ventilation.

  • Keeping your timber building ventilated is no less important than keeping your house well ventilated. This is especially true if you plan to cover up your floorboards with something (double check with an expert, that the material is suitable to do so), as moisture can become trapped between layers of non-breathable materials and build-up, leading to floors becoming rotten.

4. Regular Seasonal Maintenance.

  • Whether you opt to build your product yourself, don’t be afraid to tighten the odd bolt here and there. Your product is a life improving investment, so it’s only right to give it some love and care from time to time. Make sure that it’s properly treated before the rainy months, and you make adjustments to doors and window frames, when needed.

 

Natural Timber Properties

After building your timber product, this natural construction will begin to ‘settle’. This means that you will likely see some natural timber imperfections appear. These types of natural imperfections can include:

 

  • Cracks

 

Cracks On Wood

 

  • Splits

Splits On Timber Held With A Green Rounded Safety Cap

  • Shakes

 

Shakes On Wood Panel

 

  • Warping / Twisting

Warped wood panels, twisted Wood panels

 

  • Expansion and Contraction

Please be aware that, as these are natural timber properties they are not considered as defects under our Terms & Conditions (for more information, check out our Ts&Cs here). However, in most cases, these imperfections will not impact the integrity or function of your timber product, and/or can easily be rectified. For advice on how to rectify these and for more support, please get in touch with our Customer Services Team on cs@dunsterhouse.co.uk.
