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 summer house.
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.
Chrome Ironmongery
All Sienna and Acacia range buildings are supplied with chrome window and door furniture, bringing a high-quality finish to your summer house.
Safety and Security
A five-lever mortice lock is included as standard to make sure your building is safe and secure.

Each Sienna Pent is built to meet our customers' requirements so external colour, internal lining and flooring choices are always on the agenda.

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 Sienna Pent is 14ft wide x 8ft deep and is shown in the 'Ocean Blue' painted finish with MDF lining, insulation, and a Renaissance Oak deluxe laminate floor.
Full length double glazing is a standard feature as is the double doors.
The Sienna Pent has chrome fittings as standard, consisting of chrome door hooks, casement stays, hinges and handles.
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.
Two opening end windows are provided with each Sienna, additional windows and vents are also available if required.
We are able to offer a selection of attractive laminate floors for our Sienna range which, if you choose to have our bespoke fitting teams to install your building, will be fitted at the same time.
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.
Our standard cladding on the Sienna range is 12mm redwood ( pine ). This is treated with a wash of quality wood preserver both inside and out before it leaves the factory.
This building is also available with 'Pressure treated' or cedar cladding.
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.
Each season we take a close look at the range of laminate floors available with our garden offices to ensure they complement the external paint finishes. Here we have 'Hickory Berkeley' for the floor with the external 'Graphite' paint finish.

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.
