Extra Large Deck Box with Generous Storage in Steel Grey

An extra large deck box with room to spare

Who would not want a chest that offers plenty of storage and still looks good? This extra large deck box does both: it gives generous room for cushions and all the odds and ends that should be kept safe and protected from the weather, while also working as a handy surface and a comfortable seat on the terrace. The clean, modern design in elegant steel grey settles harmoniously into any outdoor area and sets a stylish, functional highlight there instead of an eyesore, no matter how much you fit inside.

Quality and comfort in every season

Made from weatherproof HPL, this chest stands up to UV, rain and temperature swings with no maintenance at all. The reinforced lid on gas springs opens gently and doubles as a robust seat. Height-adjustable feet level out smaller unevenness in the ground, while water-repellent seals and integrated ventilation grilles with an insect screen keep the interior dry and well aired. It is built to be used, not fussed over, and it keeps its clean look through everything a full year of weather throws at it, from summer glare to winter frost, without softening, warping or losing its edge, and without any care routine on your part.

Waterproof HPL by Trespa, a rain-safe chest

The chest is made from waterproof HPL (high-pressure laminate) panels by Trespa, a facade material engineered for the outdoors: UV-resistant, scratch-resistant and completely maintenance-free, built to hold color and precision for 50 years and more. The panels are waterproof, and together with the seals the result is a weatherproof, rain-safe chest, not a container you would submerge. Free color samples are sent to your home, so you can compare any of over 250 HPL colors and finishes against your own terrace before deciding. Whatever you pick, the finish keeps its color without any repainting or sealing.

Storage, shelf and seat in one

Because the lid is reinforced for sitting, this format earns its space three ways: put things down, sit down, and store a season of cushions underneath. Compare the sizes and finishes across our garden storage boxes and choose the volume that fits your terrace and the amount you actually need to store away. Everything that should stay close but out of sight goes into one tidy body, so a big footprint still leaves the terrace looking clear.

A steel grey that fits anywhere

The elegant steel grey is deliberately versatile, sitting quietly against decking, render or planting so the box looks planned rather than parked. The closed surfaces keep the look calm, and the generous format still reads as tidy because the proportions stay clean. It is a large box that never feels bulky, and it works just as well as an accent as it does as a workhorse.

Developed and built in Germany

Every DESIGA piece is developed in-house and manufactured in Germany, precisely prefabricated in the workshop so the finished quality does not depend on site work. That this quality ships far beyond Europe is shown by our California garden house project.
