Kit out your Building with our Premium Installation Service

At Grand Outdoor Designs, our work doesn’t end once we’ve built the shell of your outdoor building. Far from it! Our quality installation service will see your room kitted out exactly as you’d like it to be. From lighting to heating, windows and doors to joinery, our team will work meticulously to ensure that all those special finishing touches truly make your outdoor building a home.

Windows and Doors

Taking the lead from Paul Boyd, Grand Outdoor Designs brings over 25 years of experience in providing and fitting quality windows and doors. From casement to aluminium windows, French to bi-fold doors, our extensive glazing expertise will guarantee that you get excellent results, no matter what design you choose.

You’ll also be happy to know that our range of windows and doors assures the highest levels of energy efficiency, meaning that not only will you minimise your energy bills, but you’ll be doing your bit for the environment, too.


What sets Grand Outdoor Designs’ outdoor buildings apart from others on the market is their pure luxury and comfort. As such, we take delight in providing our clients with quality insulation, perfect for helping to keep you warm on those long winter nights, and cool when the mercury rises. 


Grand Outdoor Designs also offers a range of plumbing services for your outdoor building. So whether you’d like a sink, toilet or shower installed, we’ll be able to facilitate this for you.


We’re pleased to offer our customers a range of lighting options. For both interior and exterior lighting requirements, our team will help you to decide on the most appropriate choices for your room. But whether you’d like dramatic spotlighting for your pool house, or subtle sconces for your home office, we’ll listen to your vision and execute it accordingly.


With our longstanding experience in the construction industry, Grand Outdoor Designs is perfectly suited to building and installing a range of joinery products. Whether you require a large oak working desk for your studio, or aspen wood benches for your sauna, we have all the necessary skills to construct whatever particular concept you may have in mind.


For all the electrical items that you’ve been imagining setting up in your new, luxury outdoor building, the Grand Outdoor Designs team will be happy to ensure that all the wiring in your room is exactly as you’d like it.
