Adding an outbuilding to your garden completely transforms how you use your outdoor space. However, choosing the right structure raises crucial questions about materials, floor space, wall thickness, and planning permission.
This guide covers everything you need to consider before making a purchase—comparing the main building materials on the market and breaking down the key features of top-selling models.
Your choice of material directly affects a shed’s lifespan, insulation quality, and visual appeal. Here is how the most common options stack up:
Timber remains the gold standard for its natural thermal insulation and timeless aesthetic appeal. It creates a comfortable, welcoming interior that naturally buffers temperature swings. Buildings constructed from slow-grown Nordic spruce are renowned for their structural stability and durability. However, wood does require routine protective treatments to guard against moisture and UV damage.
Resin sheds are lightweight and virtually maintenance-free. They assemble quickly and stand up well to weather without rusting. On the downside, they offer almost no thermal insulation, leaving interiors exposed to extreme heat in summer and freezing cold in winter. Their lightweight frames are also more vulnerable to high winds and heavy impacts.
Metal sheds—typically made from galvanized steel or aluminum—are budget-friendly and fire-resistant. Their primary drawbacks are poor insulation and a high tendency to collect internal condensation. Additionally, their industrial look can clash with natural garden settings.
Wood-plastic composite combines timber fibers with polymer resins to deliver the warmth of wood with minimal maintenance. While durable and weather-resistant, composite panels are heavy, carry a higher price tag than standard resin, and offer fewer design variations.

Proper site prep and foundation work are crucial to keeping your garden building stable and weatherproof over time.
A solid, perfectly level foundation prevents timber warping, sticking doors, and ground moisture issues. Key options detailed in our guide on shed foundation types include:
To protect Nordic spruce against UV rays, rain, and insects, apply a comprehensive wood treatment within 4 weeks of assembly. We recommend applying a deep-penetrating preservative primer followed by two coats of a breathable exterior wood stain (lasur). Reapply every 3 to 5 years depending on weather exposure.
In Spain, outbuilding regulations vary by municipality (ayuntamiento) based on square footage, roof height, and whether the structure is classified as permanent or removable. Before assembling your shed, consult local municipal planning guidelines to confirm if you need a minor works permit (licencia de obra menor).
Choosing the right garden building comes down to matching your site layout with your long-term needs. Investing in quality Nordic timber ensures a warm, durable, and versatile space that will enrich your property for years to come.
That depends on your local municipality and the size of the structure. In most areas, small demountable sheds only require prior notification or a minor works permit. Always check local planning regulations before erecting larger or permanent buildings.
For year-round comfort, a wall thickness of at least 44 mm is recommended. In colder regions, opting for 70 mm log walls or adding floor and roof insulation will keep your workspace comfortable in any season.
Our prefabricated Nordic spruce kits are designed for straightforward assembly. Two adults with basic DIY skills can typically assemble a 9 m² to 12 m² garden shed in 1 to 2 days on a prepared base.
