An outdoor kitchen is not just a piece of garden furniture, it is a fully serviced kitchen that must perform in all seasons, particularly in the UK. That means it needs to be designed and specified properly from the outset.
One of the quickest ways to spot a well-specified outdoor kitchen is to look at where the services arrive. If gas, water, waste and electrics are positioned correctly at first fix, the rest of the installation tends to fall into place. If they are not, you are looking at expensive and disruptive changes later on.
Planning Your Outdoor Kitchen Layout
Most high-end outdoor kitchens are built using modular systems rather than fully bespoke joinery. For example, systems like COOXS offer consistent module sizing, making layouts easier to plan and coordinate across design and build teams.
Typical modules are around 700 mm deep, with widths ranging from 300 mm to 1200 mm and a standard 900 mm worktop height. This allows designers to create flexible layouts while maintaining a clean, uniform finish.
As with indoor kitchens, layouts should be organised into cold, wet, hot and storage zones. Appliances from brands such as Sub-Zero & Wolf, Beefeater, Napoleon and Big Green Egg often define these zones, particularly within the cooking area.
While a single straight run may look minimal, it rarely performs well in practice. L-shaped and island configurations provide a far better user experience, especially in social settings.
Getting Service Connections Right
Service coordination is one of the most critical aspects of outdoor kitchen specification, particularly when working with premium appliances.
Gas-powered grills from brands like Beefeater and SubWolf can require between 15–20 kW, depending on the model. This has a direct impact on pipe sizing and overall system design, so it must be addressed early. All gas work should be carried out by a Gas Safe registered engineer, with appropriate isolation in place.
Water supply is equally important. A cold feed is essential, while hot water is now common in higher-end projects. Waste should be directed to foul drainage or a compliant soak away, with proper fall to ensure performance. Given UK weather conditions, freeze protection is not optional — it should always be built into the specification.
Electrical demand is often underestimated. Outdoor-rated appliances, including induction systems from brands like Indu+ and extraction units from Novy, can significantly increase load requirements. A fully specified outdoor kitchen can easily reach 8–15 kW, so coordination with the consumer unit is essential.
Below the kitchen, proper drainage should also be included. A sloped base with integrated drainage helps manage water from rain, cleaning and general use.
Safe Clearances and Heat Protection
Appliances from brands such as Big Green Egg, gas grills and teppanyaki plates generate substantial heat, making clearance planning critical.
Adequate spacing must be maintained around all cooking appliances to protect surrounding materials and reduce fire risk. Manufacturer guidelines should always be followed and clearly detailed within drawings.
Where kitchens are positioned near walls or within structures, non-combustible materials such as stainless steel or fibre cement should be used behind cooking zones.
Designing for Covered Outdoor Kitchens
Covered outdoor kitchens are increasingly popular, particularly when paired with pergola systems from brands like KE Outdoor Design.
When working within a covered structure, extraction becomes a key consideration. High-performance, ducted systems — such as those supplied by Novy — should be specified to handle heat, smoke and grease. Recirculating systems are not suitable for this type of environment.
There also needs to be close coordination between the kitchen and pergola systems. Power requirements for lighting, heating and appliances should be planned together, avoiding the need for retrofitting later.
Lighting should be layered to support both function and atmosphere, and increasingly these systems are integrated into smart home platforms such as Control4 or Lutron.
Choosing Materials That Will Last Outdoors
Material selection plays a major role in the longevity of an outdoor kitchen.
COOXS kitchens, for example, use marine-grade aluminium cabinetry with powder-coated finishes, offering strong resistance to corrosion and weathering. This is particularly important in exposed or coastal UK locations.
For worktops, brands like Dekton, Neolith, and Laminam provide reliable porcelain surfaces that are UV-stable and non-porous. Natural stones such as marble or travertine are generally not suitable due to their tendency to stain and weather.
Appliances should always be specified for outdoor use. Brands such as Napoleon, Beefeater, Big Green Egg, and Wolf are designed to withstand external conditions, unlike indoor appliances which tend to fail quickly when exposed to the elements.
Final Checks Before Installation
Before moving forward, it is important to review the full specification in detail. Service entry points, appliance requirements, electrical loads and drainage should all be confirmed. Clearances must align with manufacturer guidance and all materials should be suitable for outdoor use
Taking the time to resolve these elements early will prevent costly changes later and ensure the kitchen performs as intended.
