28mm double glazing

Garden Offices 28mm Sealed Unit
 
28mm Double Glazing
 

Our garden offices are supplied with domestic standard uPVC windows and door frames available in White as standard or Anthracite Grey Wood Effect. So you can either tie in with your home frame colours or customise your office!

 

Not all double glazing is the same and what truly makes our double glazing stand out among the rest is the sealed unit. We supply a 28mm, double glazed sealed unit for all our garden offices. These units comprise of 2 panes of 4mm toughened glass on either side of a 20mm aluminium spacer bar, designed to absorb any moisture within the sealed unit, which could lead to condensation inside the glazing. These sealed units comply to BS EN 1279 standards. This EN standard covers the requirements for insulating glass units, including thermal and sound insulation. The sealed units are independently tested to show that they will not suffer from any form of condensation within the unit.

 

We’ve been manufacturing uPVC windows and doors for over 25 years – so we really know our stuff!

Our garden offices feature polyisocyanurate insulation in the walls, roof and floor, creating the perfect space to use as a home office or lounge room. Polyisocyanurate is known for being a far superior insulative material than the polystyrene, Rockwool or bubble wrap used by some of our competitors.

Pressure Treated Bearers

Spaceship Micro Garden Office - Pressure Treated Bearers
 
Pressure Treated Bearers

All of our garden buildings have pressure-treated floor bearers as standard. This treatment prevents the timber bearers from rotting for up to 10 years and causing your garden building to sink. Pressure treatment forces the wood preservative into the timber rather than simply dip treating (essentially just covering the exterior) like many companies still do. Who wants to have to annually deconstruct and re-treat the bearers each year!

 
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.  We do however recommend applying a good quality water repellent to the timber to prolong the longevity of the timber. Shockingly many of our competitors still offer untreated bearers to keep their costs down, so beware!
 
All our Pressure Treated timber is for User Class 3

Avoid Planning Permission
All our Garden Offices are under 2.5m high so that under permitted development rights you can place the building within 2m of a boundary if you wish to. Please be aware that any building over 2.5m high needs to be placed over 2m away from any boundary. If you want to find out more about planning permission click here

Secure Multipoint Locking on Micro Garden Office Right
 
10-Point Locking System
Security is something that shouldn’t be overlooked when designing a garden office, especially when storing valuable equipment. Which is why we have included our industry leading 10-point locking system on the wide opening uPVC doors as well as multipoint locking windows which feature secure key locking handles.
Our 10-point locking consists of four shoot bolts, three mushroom headed espagnolettes, three hook bolts, a locking latch and a 6-pin euro cylinder. All our windows feature a multi-point locking system consisting of mushroom-headed espagnolettes which move in opposite directions into metal keeps. Why would you risk your possessions by using less?

Designed for the DIY Market

Designed for the DIY Market 
All our garden buildings have been designed on the basis that any competent DIY customer should 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. We totally understand that DIY is not for everyone therefore, you may want to consider getting in touch with a local carpenter or handyman to install it for you. But before you do, check out our construction video and decide for yourself! 
 

Have a question?


What is a Garden Office?

+
A Garden Office is a garden building used to create an office away from your home, separating your work life from your home life.

A Dunster House Garden Office is made from slow-grown spruce, 4mm toughened glass and polyisocyanurate insulation (SuperFOIL on our Dominator range), creating a thermally efficient, smart looking product.

Do You Offer Any Guarantees Or Warranties On This Product?

+
We offer a genuine 10-year guarantee against rot and insect infestation on pressure treated timber.

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.

Is This Garden Office Insulated?

+
This Garden Office contains floor, roof and wall insulation. The type of insulation we use is called Polyisocyanurate, which is proven to retain heat better than polystyrene or rockwool. This Garden Office also feature 28mm double glazed units to aid in retaining heat.

Where can I visit you? Do you have a store near me?

+
We currently have 11 distribution centres across the UK. All our business is via our company website and phone - contact us. If you wish to view a particular product, we are happy to arrange a video call or send a pre recorded video to your email address.

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.

How long does it take to build?

+
This garden office will take two able-bodied people approximately 1-2 days to build, but this is a rough guide and is likely to vary based on external factors such as weather, tools, foundations and expertise.

Do you deliver to Scotland?

+
Yes, we do! Some postcode restrictions do apply however we are pleased to be able to deliver to many parts of Scotland.

For more information - Where Do We Deliver?

Does this Garden Office need treating?

+
This Garden Office is made from WPC (wood polymer composite) which needs very little maintenance. This eliminates the need for annual treatment application. We recommend wiping the external walls down with warm soapy water every now and again to stop them from getting stained.

How long will it last?

+
Your Garden Office is designed with the intention to keep it extremely easy to maintain and as long-lasting as possible. WPC is a very hard-wearing composite material which, being made of wood-plastic, is able to withstand harsh conditions over a number of years. The pressure treated bearers that the building stands on are guaranteed against rot and insect infestation for 10 years.

Does Dunster House Responsibly Source Its Timber?

+
Dunster House commit to continuously improve the sustainability level of our sourcing, by favouring stricter more credible certification and verification standards, and sourcing requirements. We are committed to avoiding sourcing from unknown or unsustainable sources.

Where possible, Dunster House are committed to procuring wood products that have been certified against credible, internationally recognised standards for good forest management, to ensure that material originates from well managed forests. In line with this, we preference products certified to the standards of FSC (Forest Stewardship Council) and PEFC (Programme for the Endorsement of Forest Certification).

What about illegal timber?

Dunster House are committed to sourcing only material that is produced, processed and traded according to applicable legislation.

What is your Environmental Responsibility policy?

Dunster House are committed to promoting responsible stewardship of the environment and its natural resources. We are committed to lessening the impact on the environment caused by our own activities, and those of our suppliers.

Do you have a Supply Chain Management policy?

Dunster House will ensure that information about suppliers and material is gathered as part of the RPP. We will ensure regular engagement with our suppliers to ensure compliance with UKTR requirements, working with them to ensure continuous improvements. We will also specify that, wherever possible, that material sourced is covered by FSC and PEFC, to ensure responsible forest management.

What are u-values?

+
U-values tell us about the heat loss properties of the material you are measuring. The lower the number, the better insulated the Garden Office will be. Find out more here.

Delivery Service

All of our products are delivered using our own fleet of vehicles, not sub-contractors. We have a large number of vehicles dedicated to delivering our quality products so we can guarantee maximum care is taken during the delivery process.


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. You will also receive a component list to check your items against. 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.


Should you require further information on our assisted delivery services, please click here to read our Terms and Conditions, alternatively you can contact a member of our Sales Team.





Q: Where can I find more information?

A: If you have any questions regarding your delivery, you can telephone our Dispatch Team. Contact details for the Dispatch Team of your nearest branch can be found on your order confirmation. If you need to track your delivery or access your manuals in advance of your delivery, you can visit the Customer Log In Area of our website https://dunsterhouse.co.uk/customer-login-area/log-in



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.
