An outdoor kitchen should not be an indoor kitchen with outdoor-looking materials.
It needs to be built from the outside in.
The kitchen in these images had been built with MDF-based outdoor material. On paper, that can sound convincing. In real outdoor kitchen use, the problem often starts later: moisture finds its way into edges, cutouts, joints and closed cabinet areas. Over time, swelling and mould can appear, even when the kitchen was originally sold as suitable for outdoor use.
That is why we are careful with material claims such as “suitable for outdoor use”.
Suitable for a facade does not automatically mean suitable for a kitchen corpus.
Rain, frost, sun, grill heat, moisture, cleaning, grease and years of real use create a different environment than any indoor kitchen will ever face. For us, the stable base matters most. That is why our outdoor kitchen corpus is made from stainless steel or Magnelis®. The visible surfaces are then chosen to match the architecture, the terrace and the way the kitchen will be used.
Kindly said: indoor kitchen builders can be excellent craftsmen. But outdoor kitchens are their own discipline.
We explain the difference in our latest blog post:
