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!

WPC Exterior Walls
You may have heard of the composite wood-plastic material that is becoming increasingly popular for use in gardens and outdoor construction such as decking and sheds. WPC has all the benefits of plastic and timber combined, meaning zero maintenance and impressive water resistance. Supplied with an eye-catching grooved finish, these composite garden offices are complete with the perfect combination of garden-use materials. It can be painted to your preference using a Multi Surface Paint, similar to 'BEDEC Multi Surface Paint'. We have used 'BEDEC Multi Surface Paint' for over eight years now and found it had fantastic adhesion, wear and colour fastness. Please note that un-painted WPC panels may vary in colour.

Fully Insulated with Polyisocyanurate Sandwich Panels
You don’t need us to tell you how important it is to have a garden room that is easy to heat, and maintain a warm temperature in the winter and cool in the summer. 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.

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.

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

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.

How to Lay a Base for your Contemporary Garden Office

A flat and level concrete base is the ideal Garden Office foundation, but if you already have a paved or decked area that you want to place your office onto, that is also a great idea. With any base, the most important thing is that it is flat, square and one hundred percent level.

Concrete Base

There is no need to add a run-off of any kind.


1. Mark out your area

When preparing a concrete base, the first thing you need to do is mark out the area that you will be using. We recommend that the base is the same size as the external dimensions of your bearer plan plus an additional 100mm on all sides.


2. Dig your foundations

You might wish to excavate some foundations for your concrete base, approximately 200mm deep for the base to sit in. This helps to flatten the surface, and you should use a spirit level to make sure that it is completely straight and that any incline is levelled.


3. Add compacted hardcore

Many customers like to add a layer of well-compacted hardcore at the bottom of the foundations to pour the concrete onto. If you choose to do so, you may need to use some timber to frame the hardcore and hold it in place.


4. Pour on the concrete

You can then add the concrete mixture and be sure to level it off using spare timber or some tools. Many customers decide to get a local builder or handyman to lay the concrete for them. After the base is ready, the rest of the build is easy for the competent DIY'er to complete.


Concrete Base


5. Double, Triple Check

If your base is not completely square and level, the build of your garden office will be more difficult and you may find that your product develops problems in the long term. Before you start building, double check that the base is flat using a spirit level and then keep one close to hand as you will need to continue using it as you install the panels. If the spirit level indicates that the base is uneven you will need to use packers.


6. Lay your bearers

Use the bearer layout provided at the beginning of your instructions to judge the size of your base and to assemble your bearers.
