Influenced by the Malvern Studio Pent, the Sienna Pent is a modern, subtle and attractive garden room. The pent style roof allows light into your garden room whilst adding a contemporary look and feel to any outdoor area. With glass to ground double glazed windows either side of the double glazed double doors, the Sienna Pent maximizes the use of available light, making it the perfect garden room for relaxing with family and friends or working on hobbies and crafts or using as a home office.
As standard each Sienna Pent has modern chrome ironmongery, a five lever mortice lock for added security, 38kg bitumen felt roofing in red, green or black, durable pressure treated floor joists and a preservative treatment throughout. Our great range of optional extras gives you the ability to tailor your Sienna to your own style. By adding either the patterned MDF or tongue and groove lining and insulation your Sienna can be used all year round - keeping you warmer through the winter months.
The Sienna, part of the Garden Living range also offers a choice of cladding profile. Choose from traditional shiplap, as featured prominently in the Malvern Studio range, or square cladding - a contemporary and stylish cladding profile.
At GBC, we are continuously striving to improve our products, methods and materials, which means we may change the specification of a product or range from time to time, but we will not make any significant changes without your agreement
Choice of Timber Cladding
Choose between 12mm redwood, 12mm pressure treated redwood, premium cedar, 19mm redwood or 19mm pressure treated redwood. The 12mm and 19mm redwood are pre-treated with a water based preservative inside and out before it leaves the factory. The 12mm and 19mm pressure treated redwood has a long-lasting treatment forced deep inside the timber giving the timber an attractive green hue which compliments gardens well. The Western Red Cedar is a beautiful and versatile timber which produces its own natural oils and preservatives making it a durable and rot-resistant species of timber, perfect for a garden summerhouse.
Double Glazed Windows and Doors
As standard, the Sienna includes full-length, double glazed windows and doors across the width of your building with a single large, full length window either end of the building. This maximises light into your building - perfect for an art studio!
Under 2.5m Height
Just like the Malvern Studio range, the Sienna is designed with a ridge height of under 2.5m so that planning permission is only needed in special circumstances.
All Sienna and Acacia range buildings are supplied with chrome window and door furniture, bringing a high-quality finish to your summerhouse.
Safety and Security
A five-lever mortice lock is included as standard to make sure your building is safe and secure.
12-Month Workmanship Guarantee
All buildings are fully guaranteed to be free from defects and faulty installation for a period of 12 months.
All our garden rooms include a guarantee against rot and decay:
10-Year guarantee for Cedar
3-Year guarantee for Pressure Treated
2-Year guarantee for Redwood.

Lining and Insulation

This Malvern Sienna Pent is 14ft wide x 8ft deep, and is available in a huge range of sizes ensuring we have the perfect fit for you.
This model features is in the standard 12mm deal cladding, with an 'Olive Green' painted finish, painted 'bead and butt' MDF lining, insulation and a deluxe laminate floor. Full length double glazing is included as standard with the Sienna range - perfect for a garden office or warm summerhouse.
The Sienna Pent has a clean, modern look about it and when you consider that installation takes less than a day and there's rarely any issue with planning permission you can see why it's such a popular choice to solve issues over lack of space.
When you start to work out how much you can save, in time and money, by working from home you'll soon realise that the Sienna pays for itself in a very short space of time.
This 12ft x 8ft Sienna Pent is shown in the stunning 'Urban Grey' painted finish. This model also features painted MDF lining in 'Honey Dew', a deluxe laminate floor in 'Seaside Pine' with an EPDM rubber roof membrane.
Each Sienna Pent is built to meet our customers' requirements so external colour, internal lining and flooring choices are always on the agenda.
The Sienna Pent is designed with a ridge height of under 2.5 metres so that planning permission is only needed in special circumstances.
This Malvern Sienna Pent is 12ft (wide) x 8ft and is shown in preservative treated cedar cladding.
Internally it is lined and insulated using tongued and grooved pine.
All glass is toughened to appropriate standards.
We can install your Malvern Sienna Pent at most locations in the UK, please ask our customer service teams at our branches for details.
The versatility of the Garden Living range is illustrated here with this full length glass model which has been finished in our attractive 'Willow Green' painted finish.
To upgrade the interior we have used 'honeydew' finished lining panels and added an attractive laminate floor too.
This is a display model at one of our branches: we display the Sienna Pent at many of our 35 locations around the UK, just drop down the page to the 'where can I see one' tab to find your nearest location.
The optional tongued and grooved pine lining inside the Sienna Pent is carefully fitted to provide a pleasant working environment. Because the walls and roof are insulated when the building is lined, the Sienna Pent will become suitable for all year round use.
We recommend heating the Sienna Pent with electric thermostatically controlled convector heaters. You can set these to maintain a minimum temperature when you aren't using the building so that paper and equipment remain at the appropriate temperature.
The internal T&G lining is shown here on the Acacia which has half length windows rather than the full length ones fitted to the Sienna.
Choose the optional MDF panels, sprayed with a honeydew paint finish, and you choose a hardwearing and attractive finish for the inside of your Acacia or Sienna Garden Office. Pictured here on the Acacia ( which has half length windows rather than the full length windows featured on Studio models ). The MDF lining helps create a light and airy feel to this working environment.
When you choose either the MDF lining, or the T&G lining pictured elsewhere in this gallery, the building is insulated too with a uFoil insulation in the walls and roof.
Our double glazed Acacia and Sienna ranges of Garden Offices, whether Apex, Pent or Pavilion style, can all be fitted with an optional integral shed conversion.
In this picture of a 14ft x 8ft Acacia Pavilion the shed section ( 4ft wide in this case ) is fitted within the LH side. Pent versions would also have the shed conversion to one side or the other whereas Apex versions would have a rear compartment as a shed section if specified.
Please note that the shed section is not lined or double glazed and comes with a joinery made single glazed shed window and a solid, framed and braced shed door.
In this picture of a 14ft x 8ft Acacia Pavilion other options are the paint finish, internal MDF lining, bitumen felt roof tiles, and laminate floor.
Please note that the amount of the building converted to shed use is up to you but is normally 4ft, 6ft or 8ft depending on the overall length of the building. The shed area is not an extension added to your building, it is part of the original dimensions.
The Sienna Pent style roof overhangs the front door giving shelter when entering and leaving the office. This also keeps the worst of the weather off the door and windows helping extend the life of the building accordingly.
The Sienna Pent is less than 2.5metres in height and therefore does not contravene planning laws ( which require you to ask permission for buildings which are more than 2.5m in height within 2m of a boundary.)
Sienna Pents have full length glass windows so you may have spotted that this picture shows the Acacia Pent with it's top light windows... but the principle is exactly the same !
Pressure treatment is literally that : all components of the building are placed in a large pressurised cylinder which forces the preservative deep into the timber. The formulation of the preservative gives our pressure treated buildings their green / yellow hue which complements so many gardens.
Good looks and an extended lifetime are the main benefits of choosing pressure treated cladding.
Cedar is well known for its durability, good looks and quality. With its own natural oils, it lasts for many , many years without rotting although we would advise you to treat it with a good quality wood preserver every couple of years to help maintain its good looks.
Our cedar Garden Offices contain cedar doors, windows and external cladding and trims.

All of our Malvern Garden Offices will be delivered and installed (where applicable) by our skilled team of fitters - ensuring that your garden office arrives in perfect condition and it is assembled to the highest standard.
Please be aware that you will need to provide a good, strong and level base constructed from either slabs or concrete. This will need to be completed prior to our delivery date, ensuring that it is set and strong enough for that building to sit on.
We will always confirm these details with you at point of order and we will provide you with base plans so that no detail is left out - ensuring that your garden office will be both delivered and installed without any inconvenience.
As with all of our garden buildings, we like to provide our customers with a suitable delivery time. We always give good notice of our arrival date, allowing you to be sure it is the right time for you. We always appreciate any helpful information regarding access to your pre-prepared base area and any details you may need to share with us about reaching you - so that the delivery process can run as smoothly as possible.
Our delivery times can vary from season to season, but typically you should expect to receive your building around 4-6 weeks from point of order. All of our buildings are made to order, so during the busy spring to summer seasons this may increase to 6-8 weeks - dependant on the building that you purchase. Please feel free to contact us on 0800 999 0123 to check our current delivery times.
