    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

      "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

      "OLYMPIAN GARDEN BUILDINGS, HIGHLY RECOMMEND. We ordered a bespoke Feathered Edge timber garden building from Olympian and would highly recommend. Very impressed by the whole process from design through to installation. The communication at every stage has been great and very happy with the end result"

      David Cook

      "We needed to create some extra space at home to create a photography studio/ office. Having spent a long time searching suppliers of suitable buildings, we eventually had a shortlist of three, of which Olympian was one and the only one whose products we could physically see, as opposed to just trusting what is on the web.

      After visiting their site and talking to Nick, we decided to go with Olympian and can honestly say that the whole experience has been pretty near perfect.

      On-site during the build, the team were punctual and hard-working, Ian and his team were a pleasure to have here.

      I can wholeheartedly recommend Olympian to anyone considering a similar project."

      Adriano Henney

      "We have a Alderley summerhouse and a large cedar build annexe comprising of a lounge bedroom and shower room from Olympian. First class service from beginning to end. The designing of the cedar build in particular meant a careful attention to detail, with a high end finish and design changes along the way, carefully managed in a professional manner by Nick and the team.

      The construction took a little over a month to create the build and Ian / Connor were precise and professional, displaying expertise craftmanship throughout.

      We recommend Olympian to everyone and could not be happier with our choice."

      Mr and Mrs Woods

      "I just wanted to pass on my grateful thanks to you all and particularly the two guys who came yesterday and built my summerhouse for me! They were very hard workers, very pleasant and excellent representatives of your company and I will be passing on the name of Olympian Garden Buildings and BGA Leisure to any of my friends who wish to follow my lead and purchase a summerhouse or garden building themselves. (Pictured 8 x 8 Apex corner chalet with premium pack, painted in Clay and Natural Stone with felt tiles)."
