    With a wide range of available styles and layouts, we will work with you to create an office that is both attractive and practical. The solid internal partition and individual external doors ensure both areas of your combination office remain independent from one other, providing a useful and versatile space that can be split to suit your particular requirements.

    All of our products are crafted from the very finest materials including premium Scandinavian timber, which we source directly from mills in Sweden and all of which is FSC certified and fully tanalised, to protect against rot and to increase strength and durability.  All of our insulated garden offices are fully double glazed, are fitted with carpet tiles and feature a five-lever locking system for added security and peace of mind. They are all completed to the most exceptional of standards with internal coving, a variety of painting options both inside and out and a choice of cladding to the exterior, including premium Thermowood.

    There are numerous upgrades available including laminate flooring with underlay, additional windows and doors and a cedar shingle roof for the ultimate luxury finish. The options are virtually endless and whatever decisions you make, you can be assured that all the materials that we use are carefully selected for their quality and performance. We are happy to advise you on the best options for your requirements as, with more than 30 years of experience in supplying high end garden buildings to homes across Cheshire and beyond, we understand what our customers want and need. Our attention to detail is second to none and as your garden office will be individually made-to-order at our on-site workshop, we can guarantee that every element will be personally overseen by our expert craftsmen.

    As a family run business, we pride ourselves on delivering a personable and seamless service from the moment of your initial enquiry through to design, installation and aftercare. We don’t outsource any part of the process so we will be fully and personally involved at every stage of your order, and can undertake any post-installation landscaping that you may require.

      What our customers think

      "Having spent hours searching the Internet for my new shed and reading endless reviews I opted for Olympian. This turned out to be one of my better choices as the service I received has been excellent from start to finish. The price and quality of the product are well matched and I have no problem recommending this company to friends and family."

      Tim Lee

      "We have just had a 5m x 3m Garden office built on site by Olympian Garden Buildings and the whole job, from design to build was done very professionally and with minimum fuss and inconvenience. The team of craftsmen; builders, plasterers, electricians worked seamlessly to complete the project on time and the organisation behind the scenes was impressive. Nick was always available to assist with help and I wouldn't hesitate to recommend this company to others thinking of having an office built in the garden"

      Stephen Jackson

      "I would just like to say how much I love my summerhouse which I bought from you and had delivered. I am so pleased with it. The four young men that came were really nice and polite, such a joy to have pleasant work men."

      Wendy Jones

      "Fantastic service from Olympian Garden Buildings. Having purchased a couple of sheds in the past we then purchased a 16x8 foot lovely garden building with a cedar wood tile roof and a beautiful Gazebo surround for our hot tub, also with a cedar tiled roof. Dealing with Nick and his team was effortless, superb knowledge of construction and design. They did exactly what they said they would do when they said they would do it. The quality of the buildings and the construction by the team was fantastic, even in some appalling weather! You most certainly get what you pay for, and competitively priced. Coming back to put the finishing touches to the Gazebo, the team could not have been more knowle"

      Oliver Bamber

      "I love my office… secure, insulated and a superb place to get my head down and get my work done. The team were fantastic reference my requirements, budget and the installation. Absolutely delighted with it. Could not recommend Olympian highly enough."
