The Dukesbury makes a statement in any garden with its beautiful hipped roof and fully glazed front. The standard roof covering is Felt Roof Shingles with four colours available; it can be enhanced further with the Eco-Slate effect roof tiles, Cedar Shingles or Cedar Cladding. Full length front windows to match the fully glazed double doors make a superb modern looking garden building. One side window on either side of the building are also included as standard with top-openers for ventilation. All sizes come with 4ft double doors as standard, these can be changed to 5ft double doors at a small additional cost.

Tanalised Bearers

Prolong the life of your building by raising it up on tanalised bearers. These 3” x 3” pressure-treated timbers allow additional air circulation under your building thus protecting your floor joists and floorboards during wet weather.

Insulated Floor

The walls and roof of the Elite range of summerhouses are insulated as standard. The flooring can be upgraded to be insulated also, recommended for all year round use.


For larger buildings, adding on guttering is a great idea. You could attach a water but at a later date to collect rainwater.

Cedar Slatted Roof

A lovely addition, cedar-clad roofing slats will enhance the appearance of any building. The roof is felted as standard underneath the cedar slats.

Cedar Shingle Roof

This is a lovely looking addition for that traditional roof appearance.

Eco Tiles

Charcoal grey Eco-tiles can be added to apex or pitched-roof buildings, a great looking roof option that looks like real slates.

Building Made To Go Through Doorway

Most of the Elite range of buildings have large components when manufactured in the standard way and cannot fit through a doorway with restricted height clearance. These larger buildings can be manufactured in smaller components if necessary if access to the garden is an issue.

Additional Doors

Add another pair of doors to your building, this is a popular optional extra for larger buildings.

Additional Windows

Extra windows can be added if additional light and ventilation is required.


The Elite buildings can be split by specifying a partition, use one section for a relaxing garden room and the other for storing garden tools and garden furniture for example. The price includes an additional glazed UPVC door; this can go within the partition or elsewhere in the outside walls of the building. The partition wall is also insulated.

Additional Paint

For spray-painted buildings additional paint can be ordered.

Delivery and installation is included in the price to all of England & Wales. 

Addresses in Scotland please email or phone to enquire giving us your postcode and which model / size you would like.

Sorry we do not deliver the buildings to Ireland, Isle of Wight, Isle of Man or the Channel Islands.

What is the delivery lead time?

The current lead time is 12 weeks, add an extra week for cedar clad finish.

What is included in the price?

All prices include delivery, installation and VAT. These buildings are insulated as standard (walls and roof), have double glazed doors and windows; currently, external painting and laminate flooring is also included. Delivery restrictions may apply; see the Delivery Information tab for more details.

Has the timber on my new garden room been treated?

Yes the buildings are fully submerged in the dip-tank at the factory, treated with a Protek water-based treatment product. At present the external spray painting is included in the price, your building will receive 2 coats of spray-paint on top of the dip-treated timber.

Can you provide an installation service?

Yes, the price includes delivery & installation providing you have a perfectly flat, level, solid base and good access into the garden.

Are the dimensions given internal or external?

The dimensions given are external and in most instances are full Imperial measurements. When measuring, please allow for roof overhang.

What base do i need for my garden room?

A flat, perfectly level slab or concrete base, the same size as the building as a minimum or ideally, slightly larger. Take care when laying a base near to a boundary fence or wall, please bear in mind that all buildings have side and rear roof overhang. If you need to know the overhang dimensions please ask for details.

Is my new garden room insulated?

Yes, the walls and roof are insulated as standard; an insulated floor can be added as an optional extra. The doors and windows are double glazed and have toughened glass.

What kind of access do i need into the back garden?

Please consider the dimensions of your garden room when ordering. Most buildings require 8ft height access for some of the sections to be carried to the base. We do not take buildings over garage roofs, high fences, walls etc. If necessary, buildings can be custom made in smaller components so they can fit through a restricted access; this carries a 7% surcharge.

What are the payment terms for garden rooms?

We take a 15% deposit if the building is ordered in person at our premises and the balance is payable to the installers either in cash, BACS transfer or by credit / debit card. On-line orders are paid in full at the point of order.

What guarantee do i get with my garden building?

There is a 12 month guarantee against leakage, doors sticking and lock failing.

Can you do made to measure buildings?

Yes we can, within reason, as long as the building is square or rectangular. If you require an 11’ x 7’6” for example, please refer to the next standard size up - 12’ x 8’. We cannot supply buildings with walls that taper from front to back or that do not have 90 degree corners.

What size vehicle will my building be delivered on?

It will be delivered on a Transit sized, flat bed vehicle.
