Leviathan Chunky Corner Gazebo Overview

Our attractive, high-quality, Leviathan Chunky Corner Gazebo is perfect for entertaining friends and family dining. It also acts as a cover for barbeques and garden furniture, so get the party started with this fantastic Gazebo.

Key Features

  • All fixings included at no extra cost
  • Pressure treated, NOT dip treated
  • Slow grown Spruce, not cheap Pine. Built to last!
  • Solid wooden walls for protection and privacy
  • Heavy duty timber, built to last!
  • 10 Year guarantee on pressure treated timbers

It is supported by thick 120mm x 120mm posts which ensure the whole structure is strong and sturdy. The timber used in the construction is pressure treated to ensure that it is free from fungal decay and insect infestation.

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].

There’s no need to ‘duck’ on the way in through our quality wooden gazebos. With a tall walkthrough height of 6′ 11″ (2.12m) you’re free to move in and out of your gazebo concussion free. Just what you need when hosting a garden party of taking a dip in your hot tub.

 

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!

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

All of the timber in this garden building has been responsibly sourced and pressure-treated to ensure it lasts. Pressure treatment forces the wood preservative into the timber rather than simply dip treating (essentially just covering the exterior) like many companies still do.

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

All our Pressure Treated timber is for User Class 3.

10 Year Guarantee on Pressure Treated Timber

All of our timber Pergolas, Gazebos, Carports and Porches are fully pressure treated as standard. We take the pre-cut lengths of timber and place them in a large pressure treatment tank, where the timbers are impregnated with a non-toxic preservative. We add a colourant during this process, giving the timber a rich brown colour. By pressure treating the timber, we can offer a genuine 10-year guarantee against rot and insect infestation. We only suggest that you apply a good quality water repellent to prolong the longevity of the timber.

All our Pressure Treated timber is for User Class 3. It involves the application of preservatives using a vacuum.

The below image is a figurative example of how pressure treatment penetrates wood more effectively than the dip treatment technique which does not penetrate wood in the same way, often only providing a surface coat of treatment and stain. This method therefore offers less resistance to rot and decay.

Pressure treated timbers

Unlike some competitors, we pressure treat our timbers and what is more, we treat only after cutting to ensure no timber ends are left exposed!

A lot of dip-treated sheds require a preservative to be added upon installation or within one year of purchasing their sheds. Ours do not require this, saving you time and money!

 

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.

Outdoor Living Slow Grown Spruce

Outdoor Living Slow Grown Spruce II

Our thick tongue and groove roof boards are made from 19mm pressure treated slow-grown spruce. This heavy-duty material is perfect for withstanding anything the British weather can throw at it. Supported by full lengths of heavy-duty purlins, which come in a whopping 140mm x 45mm. These oversized purlins will prevent the roof from sagging.

We use chunky 120mm x 120mm posts which not only look pleasing but they also support the heavy-duty roof purlins, guaranteeing a strong robust structure which is built to last.

Heavy Duty Structure

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

When we say chunky, we mean chunky! Our 120mm by 120mm chunky posts are made using high-quality spruce which has been pressure treated, before going through a laminating process which bonds the timber together. By laminating the timber, we can create a strong post which is less likely to shrink, swell and twist.

 

We also router grooves into the posts to not only give a distinctive look and mask the joints but to also further reduce the likelihood of the timber twisting. Most of our competition provide you with what they believe to be large posts, commonly 115mm thick. But when it comes to chunky gazebos, we think bigger is better!

120mm Posts

If you have any concerns about how to fix your gazebo to the flat and level surface you are installing it onto, you can use the L-Brackets included in your fixing pack to attach these to the feet of the upright posts, as shown in the picture below. We would not advise burying the timber into the ground.

This Garden Structure is 3.04m (9' 11") high

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.

I was surprised with the amount of timber the pagoda was delivered in but the two guys who off loaded it were very reassuring and said they had never known any items being missing. The instructions were very comprehensible and whilst it has taken me a few weeks to erect it it has been a very rewarding project. Thank you Dunster House !!
