            The 12 x 12 Ultima Pergola from Forest creates a beautiful focal point for your garden Ideal for training climbing plants across the top of the structure, you can create a stunning, scented, floral walkway bursting with colour, or perhaps a little shady spot so you can relax and dine al fresco underneath. Wisteria is always a popular choice, but we are certain you will love how your pergola looks when adorned with your favourite climber! 12 x 12 feet of space (3.6m x 3.6m) underneath gives you a lot of room, however we know not everyone has a garden that can fit such a substantial structure. That is why a 9 x 9 version (2.7m x 2.7m) is available for those who love the look of the Ultima but don’t have room in their garden for this size. Either way, there’s plenty of space underneath the Ultima Pergola, meaning you have lots of room for garden furniture. Get yourself an outdoor table and chairs or perhaps a picnic bench for the ultimate outdoor dining experience, or why not instead go for some rattan furniture or a weatherproof sofa for a simple chill out spot? However you see yourself relaxing under your new pergola, it’s certain to improve your enjoyment of the outdoors.

            Plus, when painted in a colour of your choice, you can really ensure your Ultima Pergola steals the show. We have seen loads of examples of how fantastic it can look with a splash of colour to complement the rest of a customer’s garden. Many manufacturers recommend Protek Paint for the unbeatable protection it provides your timber and the wide range of colours to choose from – get the best from your Pergola by picking one of their 60+ gorgeous shades!


            The timber is pressure treated, giving an excellent lifespan and unbeatable protection against rot, fungal decay and weathering. The timber is smooth-planed for a stunning and almost splinter-free finish. This is all backed up by a 15-year anti-rot guarantee. The FSC certified timber used is all sustainably sourced and of the highest quality, ensuring a durable build. The pergola posts are sturdily made and can be sunk into the ground; otherwise, any good bolt-in shoe for the legs will allow you to fix your pergola to a range of surfaces. Delivered flat packed with all fixtures needed, and easy-to-follow instructions.

            Upon Delivery

            Your order will be delivered kerbside or on your driveway. Due to health, safety, and insurance liabilities, the driver will not be able to take your goods to the back of your property but – upon request – may place the product at the side of the house if there are no access issues. This is to avoid risking damage to your property while delivering to an unsafe location. We will not be able to go through your property.

            We advise against arranging for a third party to install the product before its delivered and checking that all parts are present,  we cannot be held liable for any third-party costs caused by delays.


            If you have selected the service for installation, we can confirm that delivery and installation will occur on different days, and the length of time required for delivery and installation will depend on the specific item you have chosen. You will not be able to pre-book a delivery or installation date when placing your order, as this will be arranged directly with the manufacturer. Within 5 working days of placing your order, the manufacturer will contact you via email to explain how to prepare the base for installation. The base must be either a solid, level timber supportive base, concrete, concrete slabs, or a pro shed base (plastic base). You should ensure that there is a clearance of 18 inches (450mm) of working space around the base so that the installers can access all areas of the structure. Shortly after receiving the email from the manufacturer, you will receive a phone call to schedule a convenient delivery and installation date. Installation may occur within 15 working days of delivery.   Note: This service is not available on all Forest products, please check if this is available for your chosen product under the 'Choose Additional Options' above.


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