Outdoor sheds

In general, smaller outdoor sheds that aren't permanently anchored to the ground with masonry work often fall under simplified building rules, but regulations vary from municipality to municipality depending on local building codes, landscape restrictions and the size of the structure. Before buying, we always recommend checking with your local municipal technical office.

Garden sheds can sometimes qualify as an eligible addition under renovation tax deduction schemes or the "green bonus", depending on how they're installed and invoiced. Deduction rates change every year, so for accurate guidance on your specific situation we recommend speaking with an accountant or a tax assistance centre (CAF).

Anchoring depends on the model: Biohort steel sheds come with screws and ground anchors included, while several Keter models allow the use of a base frame or a concrete/pier foundation as an anchor point — essential for achieving the stated snow load and wind resistance ratings.

Sizes vary widely: from compact boxes for a few tools, such as the Keter Store-It-Out Midi, to sheds with several square metres of interior space, such as the Keter Oakland 759 or the Biohort HighLine, designed to hold lawnmowers, garden furniture and bulky equipment.

The ideal spot is a flat, stable, well-drained surface, ideally sheltered from prevailing winds and easily accessible for moving heavy items. You should also check the required distance from property boundaries under your local building regulations, especially for larger models.

There's no single limit that applies everywhere: it depends on your municipality's building regulations and, often, on the available buildable volume on your plot. Before choosing a larger model, such as the multi-square-metre Keter or Biohort sheds, check the limits set by your local municipality.

Assembly time varies by model: many Keter sheds are designed for DIY assembly in just a few hours with common tools, while Biohort steel models require more precision during assembly. If you'd rather not do it yourself, we offer a professional assembly service that handles everything from delivery through to final installation.

The ideal base depends on the weight and intended use: a concrete slab or a pier foundation provides maximum stability, while lighter models can sit on compacted gravel or a base frame like those available for the Biohort Europa and HighLine sheds. Many models, such as Keter sheds, already include a built-in raised floor.

Assembly generally follows the instruction manual supplied with the product: you start with the base or frame, assemble the panels and walls, fit the roof structure, and finally add the doors and windows. Assembly time ranges from a few hours for simpler Keter models to more involved work for steel structures. Alternatively, our professional assembly service takes care of the entire installation for you.

There's no objectively "better" material — it depends on the intended use: resin, as used in Keter sheds, is lightweight, maintenance-free, UV-resistant and has a wood-effect look; galvanised steel, as used in Biohort sheds, offers superior structural strength and longer warranties (up to 20 years). Both are valid, long-lasting choices for outdoor use.
