A well-built deck is more than just timber and screws — it’s the start of countless moments outdoors. From morning coffees in the sun to family dinners under the stars, it becomes part of your everyday life. That’s why every deck we build is treated with the attention it deserves.
Our approach combines traditional craftsmanship with a modern eye for detail. We believe that true quality is found in the small things — the perfect cut, the smooth join, the finish that stands up to years of use. From the first design sketch to the final screw, nothing is rushed and nothing is overlooked.
Every project is a fresh opportunity to build something meaningful. We focus on creating outdoor spaces that feel natural, welcoming, and built just for you. With durability at the core and design as a priority, our decks aren’t just built to look good — they’re built to last, and to be lived on.

Everything You Need to Know - FAQs
Answers to Your Most Common Renovation Questions. If you have any other questions, feel free to contact us.
How often does decking need treating in the UK?
To keep your decking in good condition and protect it from the UK’s damp and unpredictable weather, it’s generally recommended to treat it once a year. Regular treatment helps prevent issues like moisture damage, algae growth, and fading caused by sun exposure. Depending on the type of timber and how exposed your deck is, some decks may require more frequent care, while others can go slightly longer between treatments. We always provide advice based on the materials we use and the specific conditions around your home, so you can easily keep your deck looking great and performing well for many years.
What is the best treatment for wooden decking in the UK?
The best treatment for wooden decking in the UK is a high-quality decking oil that offers protection against moisture, mould, and UV damage. Decking oil penetrates deep into the wood, helping to prevent cracking, warping, and fading caused by the changing British weather. It also enhances the natural look of the timber while keeping it nourished and water-resistant. For added protection, especially in shaded or damp areas, an anti-slip decking treatment can also be applied. Regular maintenance, typically once a year, will keep your deck looking its best and extend its lifespan.
How long does decking last in the UK?
With the right materials and proper care, wooden decking in the UK can last anywhere from 15 to 30 years. The lifespan depends on the type of timber used, the quality of construction, and how well the deck is maintained over time. Regular cleaning, annual treatment with decking oil or stain, and prompt repairs of any damage will help your decking stay strong and looking great for many years, even with the challenges of the British weather.
Do I need to get planning permission for my decking?
In most cases, you do not need planning permission to build decking in the UK as long as certain basic rules are followed. The decking must be no more than 30 centimetres above ground level and should not cover more than 50% of your garden when combined with other structures like extensions or sheds. Building regulations usually do not apply unless the decking is raised significantly or attached directly to your house in a way that affects its structure. Even though permission is not normally required, it is important to plan carefully, especially if your property is in a conservation area, close to neighbouring boundaries, or has any restrictions placed on it. A well-designed deck that respects local guidelines not only avoids any future issues but also blends naturally with your outdoor space, adding lasting value to your home. Before starting any project, we recommend double-checking with your local council if you are unsure, and we are always happy to offer advice to make the process smooth and worry-free.
Can I still install decking if my garden is sloped?
Yes, you can absolutely install decking on a sloped garden, and it is often one of the best ways to create a level, usable outdoor space. Raised decking can be carefully designed to follow the shape of your garden or to create flat, stable areas for seating, dining, or relaxing. By using supports and a strong subframe, we can build a deck that is safe, durable, and tailored to the natural layout of your land. In fact, sloped gardens often offer the opportunity to add interesting features like multi-level platforms, steps, or built-in seating areas. Careful planning is essential to ensure proper drainage, structural stability, and easy access, but with the right design and construction, a sloped garden can be transformed into a beautiful, practical extension of your living space.
Is it possible to place a hot tub on my deck?
Yes, it is possible to place a hot tub on your deck, but the deck must be properly designed and reinforced to safely support the additional weight. A hot tub filled with water and people can weigh several tonnes, so the structure underneath needs strong, carefully placed supports to handle the load without any risk of movement or damage. When planning your project, we take into account the size and weight of the hot tub and build the subframe and foundations specifically to suit these requirements. With the right preparation and construction, your deck will be perfectly equipped to hold a hot tub safely and securely, allowing you to enjoy a relaxing and durable outdoor space for years to come.
