            Revamp your garden with the Cali 16 x 12 Pent Garden Office, a contemporary and versatile summerhouse that exudes style and sophistication. Its pent roof and fully glazed double doors flood the interior with natural light, creating an inviting and spacious feel, perfect for a chic office space.

            This top-of-the-line wooden summerhouse offers ample space to transform into an office area, a cosy seating area, or a home gym. The fully glazed double doors provide excellent ventilation and natural light. At the same time, the engineered wood board with a cedar finish offers superior resistance against damages like peeling, cracking, buckling, and chipping.

            In addition, the summerhouse is treated with advanced adhesive resins, water-resistant waxes, and zinc borate to prevent fungal decay and insect damage. The interior cladding comprises a moisture-resistant MDF board with an Oxford profile finish. The walls and roof are insulated with YBS Airtec Double insulation to regulate the internal temperature.

            The tongue and groove flooring is fortified with 25mm Celotex insulation and features a herringbone vinyl finish for added strength and a premium look. The summerhouse also boasts handcrafted joinery on the windows and doors, with an option to upgrade to UPVC or aluminium windows and doors in anthracite grey, black, or white. Choosing this option will extend the delivery time. These options will reduce the door height slightly, and prices are available on request.

            Investing in the Cali 16 x 12 Pent Garden Office is a wise decision for any garden. Professional installers will handle the installation, but it's essential to prepare a solid and level base before delivery. Get ready to experience a stylish and practical garden room that's visually appealing, safe, and comfortable.

            Your Dream Space: Luxurious Building with Exquisite Pre-Painted Finish

            About Your Order:

            The Shire Garden Office Pod is a British-made garden building made from FSC® certified timber. You will get a low-carbon footprint summerhouse made from ethically sourced materials. It comes with a 10-year warranty. 

            Price includes assembly by Shire’s professional fitting team. You’ll need a firm and level concrete base. Our manufacturer’s assembly team will contact you requesting images of the base.  Occasionally, they may visit the site to confirm the base is suitable for assembly. Once they have confirmed the base is appropriate, you will be given a delivery/assembly date (delivery and assembly are on the same day).

            Please note: Images depict the summerhouse pre-painted and with furnishings and accessories; these are for illustration purposes only and are not included with your order.

            Garden Office Aftercare

            The home garden office has been treated using a proprietary zinc borate-based process.  As this is an advanced treatment, it makes it a maintenance-free garden building. If required, you can repaint the building to keep it looking new.

            We provide FREE delivery to most mainland UK postcodes; however, certain regions might have an additional surcharge, and a few postcode areas are outside our coverage. To verify availability and potential surcharges, please use the 'Delivery cost checker' tool above with your postcode.

            Delivery and Installation Timeframes

            We offer same-day delivery and installation services. While we strive to complete the installation on the same day, larger buildings may require more than one day for installation. You can find the estimated delivery and installation lead time for this product on the product page above. Our lead times are calculated in working days (Monday - Friday) and do not include Bank Holidays. These estimates are sourced from the manufacturers and serve as a general guideline, subject to fluctuations in demand. We provide this information in good faith to represent the expected delivery during that period. Please note that some remote areas might experience slightly longer lead times.

            Booking Delivery and Installation

            By entering your postal code in the ‘Pick a delivery day. ENTER POSTCODE’ Box above you can select a delivery/installation date. The evening before this date you will be sent a text message (where a mobile has been provided) with an estimated delivery window.  This update can only be provided where a mobile number has been supplied on the billing address section at the time of checkout.

            Delivery and Installation Procedure

            Within 5 working days, Shire, the manufacturer, will reach out to you. This communication will be via either a text message or an automated telephone message. If a mobile number is not provided, the latter method will be used. This message will include the necessary website link where you can review and accept the assembly's terms and conditions. Prompt acceptance of these terms is crucial to avoid any potential delays. Once you've agreed to the terms and conditions, Shire will contact you within the specified timeframe to arrange the delivery and assembly date for your order. Please note that this process might take more time during peak seasons. Keep in mind that the installation team will require unobstructed access to your garden, a minimum of 18" clearance around the building, and a solid, level foundation. It's important to know that Shire's installation team cannot bring the building through your home, as they lack the insurance coverage for entering a customer’s property.

            Delivery Day

            The manufacturer, Shire, handles the delivery process. Typically, this item will be delivered using a 17-ton flat-bed vehicle, similar in size to a council refuse lorry. Deliveries are scheduled within the time frame of 7 am to 7 pm."


            Please note: all imperial measurements are approximate and Shire Garden Offices are made from metric measurements. We would recommend that the base is at least 50mm bigger in each direction.
