Deore Offset Wooden Garage Inc. Barn Doors Overview

Protect your car and have extra storage space with our Deore Wooden Garage / Workshop. This expertly designed wooden garage is sturdy and built to last, protecting your car against the elements. This high-quality garage is made from slow-grown Spruce, which is superior to Pine, and 24mm double-glazed, toughened glass, instead of cheap styrene or horticultural glass.

Key Features

  • Quicker DIY install with pre-assembled windows
  • Interlocking log walls. Strong and robust
  • Adjustable storm braces included. Protect your garage
  • Slow grown Spruce, not cheap Pine. Built to last!
  • 10 Year guarantee on pressure treated timbers

Our stylish wooden garages are the perfect alternative to an expensive concrete garage. Made from a natural material it blends well into the outdoor environment. Designed with the DIYer in mind, this wooden garage comes pre-cut and pre-notched for quick and easy assembly.

Additional Information

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

Cracked climbing frame timbers

Splits

Split Timbers

Shakes

Timber Shakes

Warping / Twisting

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 Terms and Conditions. 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 [email protected].

With the barn doors 6′ 6″ (1.99m) wide, you can easily manoeuvre your larger furniture and items in and out of your log cabin. These wide opening barn doors and large space make this log cabin the ultimate garden workshop.

Wide Opening Barn Doors

There is nothing more annoying than being in the middle of building something and finding that you don’t have the right fixings to continue. We include all of the screws, nails and fixings that you will need to put your garden building together – not many of our competitors are that thoughtful. This eliminates the need to worry about the type of screws or the length of nails you might need to get started – it’ll all be with your delivery.

Fixings Included

Unlike our competitors, we only use high-quality spruce timber on our wooden products rather than cheap pine or mixed timber. Why do we use slow grown spruce rather than the much cheaper knotty pine alternatives?

Spruce is considered more stable as it expands and contracts less than pine. This stability means that the spruce timbers in our garden buildings minimise splits from appearing as the timber changes along with the weather.  We responsibly source all our timber, where it grows slowly in the cold northern regions. We all know the old adage of counting the rings to see how old a tree is, well our timber grows slower and takes longer to get to size meaning it has more rings in it. This means it has a tighter grain, and each ring helps prevent cracks and shakes from appearing in the densely packed timber.

Our wooden garden buildings and climbing frames really are built to last therefore we use only the highest quality, slow-grown spruce.  Spruce is much more resilient to warps and splits compared to its cheaper alternative pine. Being a whitewood, it doesn’t discolour anywhere near as much as pine so it is also much more aesthetically pleasing for a garden structure. Considered more stable, less knotty and resinous than pine, spruce will also produce a lot less sap. It is also less dense meaning it is not as susceptible to mould and rot.

We only use full lengths of timber in our garden products – we don’t glue separate offcut pieces together with finger joints. Not only are they stronger, but they look much better too.

Other companies are happy to provide you with rough offcuts, mixed timber and finger jointed timber, creating an odd-looking weak garden building with an off-putting appearance.

No Glued together Offcuts Good

We don't use Glued together Offcuts

You’ve probably at some point left the window open and it’s suddenly started to rain. Usually, this would be an issue for log cabins with normal window hinges as they could rust. However, there’s no need to panic as our expertly joined windows come with our 5-star stainless steel friction stays, typically found on the uPVC windows in your home. This eliminates the needs for the typically found stay arm openers, commonly used on log cabins.

solid windows for log cabins

Your security is of the utmost importance to us.  You have invested your precious time, thought, and money into creating your perfect garden building, therefore we want to ensure your valuables are as safe as they would be inside your own home.

Our doors feature an industry-leading domestic standard 4-point locking system consisting of espagnolettes, which slide in opposite directions as well as a 6-pin Euro cylinder, which has been tested to BSEN 1303:2005 classification. Making it difficult for intruders to break in and steal your precious belongings.

Most companies will use a cheap and simple 2-point locking system. For us it’s a no-brainer – why would you compromise your security when we offer the best on the market!

Our windows use espagnolettes, which pull the window tightly into the draft seals attached to the frame. We also supply a solid handle and key that allows you to lock the window whilst you’re away. Most competitors only supply a multi-purpose stay arm opener for both locking and keeping the window open.

Unlike other log cabins on the market ours are supplied as standard, tie the log cabin together and are adjustable. Our adjustable storm braces allow for natural movement of the cabin, which helps prevent gaps appearing between wall logs as the logs settle and move.

Garden Log Cabin With Storm braces included

Our garden buildings feature key-lockable outward opening windows, so you don’t lose internal space, allowing you to accommodate furniture underneath the window. Our windows have been designed to include draft seals that prevent wind and rain from entering your garden retreat. You may think it’s over the top, we think it’s just standard.

Ventilation is essential for the longevity of the Garden Building. This is to ensure airflow and minimise moisture at all times. We have provided ample vents to ensure that condensation is never a problem. Some competitors charge you extra for these or do not even offer them.

Vents Included with cabins

The bearers of your garden building are pressure treated to help protect your garden building from the ground up. We provide a 10 year guarantee against rot and insect infestation for all pressure treated timbers.

Unlike some competition, we can offer a genuine 10-year guarantee against wood-eating fungal and insect infestation on pressure-treated timber.

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.

We use 4mm thick toughened glass, not Perspex or Styrene which can scratch easily and cloud up over time. This is also thicker and less likely to break when hit with the neighbour’s pesky football compared to the industry standard of 3mm horticultural glass.

Toughened glass Not cheap styrene

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!

Our cabin logs are designed to interlock with a chamfered finish to ensure a snug fit. The chamfered notch system is designed to prevent damp or wind penetration. Our interlocking logs make for speedy installation and minimal need for tools. 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.

Unlike some competitors, we provide interlocking precision-engineered chamfered logs. Keeping your log cabin watertight and free from unsightly draft-producing gaps.

We were the first on the market to provide tall walkthrough height to the UK market. There’s no need to ‘duck’ on the way in through our quality single side door. With a tall walkthrough height of 6’2″ (1.88m) you’re free to move in and out of your garage concussion free. There are other companies who have tried to copy us but have had to include the doorframe as part of the walkthrough height!

We supply you with six robust strap hinges to hang your barn doors with. These strap hinges are not only screwed in to place but bolted through both the door and the framework, making it harder for intruders to remove the barn doors and enter the garage/workshop.

Purlins are the large timbers used for structural support in buildings. We use very thick, heavy duty roof purlins to support your garden building.  At 140mm x 45mm they are amongst the thickest purlins available on the UK market. Competitors will often use thinner purlins to keep their costs down which means their roofs will not be as strong as ours. Using thinner purlins risks the roof collapsing or sagging during extreme weather – and that’s the last thing anyone wants!

It is 2.91m (9' 6") high

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.

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

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.

We do not currently offer installation. 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.

We recommend a flat, level base at least 100mm bigger on each side. e.g. A W4.0m by D3.0m garden building would have a base of 4.2m by 3.2m See more details here.

A Log Cabin is a garden building constructed using individual lengths of timber (logs), which interlock to form a solid structure. Log Cabins can have numerous uses, such as a garden retreat or garden office, an extra family room, a games room, a music room, a gym… the list is endless.

Our Log Cabins are made from slow-grown spruce, and feature pressure treated bearers, 4mm toughened glass and domestic locking systems.
