How to choose the perfect metal tool shed for your garden?
A metal tool shed is one of the most practical solutions you can introduce to your garden. Durable, weather-resistant and extremely easy to maintain, it is perfect for storing tools, creating a mini workshop, a bicycle storage room or a woodshed. But how do you choose a model that will really meet all your expectations? Check out our suggestions.
Determine your needs – what will the shed be used for?
Before you start browsing catalogues, comparing colours and clicking ‘add to basket’, it’s worth taking a moment to ask yourself a few key questions. Choosing the perfect metal garden shed starts with… you and your garden:
- Do you need a shed just for garden tools? If so, a compact model with a basic shelf and a small space for standing tools will suffice.
- Do you also need to store bicycles, garden furniture or a lawn mower? In this case, consider a larger model with double doors, anti-burglary protection and good ventilation.
- Does your shed need to serve an additional function, such as a mini workshop, woodshed or storage space for seasonal items? If so, you should consider modular models or models with an extension option.
- How big is your garden and how much space can you allocate for a shed? Remember to leave at least 30-50 cm of free space around the shed for access, gutter installation or painting the fence behind it.

The most common mistakes when choosing a metal tool shed
Choosing a garden shed should be a well-thought-out decision – a hasty decision often ends in frustration, the need for reconstruction or… a second purchase. Here are the most common pitfalls that you can easily avoid:
Too small:
This is one of the most common mistakes. Users often focus only on their current needs (e.g. space for a lawn mower and rakes), forgetting about the future – more tools, additional garden furniture, bicycles.
BHB tip: always choose a model that is at least 20% larger than you think you need – the extra space will quickly come in handy.
Lack of adequate ventilation:
Metal structures can heat up in summer and condense moisture in winter. Lack of ventilation promotes corrosion and unpleasant odours.
BHB tip: MAFAL models have integrated ventilation systems – no additional intervention is required.
Ignoring the style of the garden:
A shed should not only be functional, but also fit in with the style of your garden. A brightly coloured metal shed may clash with a rustic setting, while a classic wooden shed may not suit a modern house. Check our article “Ideas for garden shed colours”.
BHB tip: MAFAL offers both RAL colours and wood-effect finishes to make it easy to match the style of your garden and achieve an attractive look.
No prepared ground:
Even the best shed loses its properties when it stands on an uneven, damp surface. There is a risk of door warping, installation problems and moisture inside.
BHB tip: It is worth preparing levelled paving stones, a concrete slab or a point foundation, depending on the size of the shed.
Key technical parameters – what really matters?
At first glance, most metal houses look similar – simple construction, metal coating, doors, roof. But what determines their durability, safety and comfort of use is hidden in the details. Here are three pillars that are worth checking carefully before buying:
1. Thickness and type of sheet metal
This is an absolute must – because it is the sheet metal that determines how long your shed will remain intact. The best structures are made of:
- galvanised steel sheet with a minimum thickness of 0.5 mm,
- additionally coated with acrylic, which protects against corrosion, UV radiation and mechanical damage.
This coating not only increases durability, but also makes maintenance easier – just rinse with water and you’re done.
Warning! Cheap houses made of thin, uncoated sheet metal can rust after the first winter.
2. Assembly system – do not ignore the instructions
Some houses look great in the catalogue, but once you open the package, it turns out that assembling them is a real challenge. Therefore:
- choose prefabricated models with marked components and clear instructions,
- check whether the house can be assembled on your own or whether it requires specialised equipment or professional assistance,
- ask about the assembly time – good structures can be assembled by two people in one day.
Interesting fact: models with a snap-lock connection system reduce assembly time by up to 40%.
3. Security and ventilation – comfort and safety in one
A metal shed should protect not only against rain, but also against thieves, moisture and overheating. A well-designed model should offer:
- a ventilation system, e.g. grilles in the walls, which prevent sheds condensation and ensure air circulation,
- lockability,
- roof and door seals that protect the interior from leaks and dust.
What else should you pay attention to?
In addition to the basic technical parameters, it is worth paying attention to a few practical aspects that are often overlooked when purchasing:
1. Foundation
A stable base is essential for durability. The shed should be placed on paving stones, a concrete slab or point foundations. This is not only a matter of safety, but also protection against moisture and settling of the structure. Read our article “Common types of Garden Room foundations”.
2. Access to the interior
Consider how often and how you will use the shed:
- sliding doors are ideal for small gardens,
- while traditional swing doors provide more light at the entrance.
Also make sure that the entrance is wide enough to easily bring in larger items such as a lawn mower, barbecue or bicycle.
3. Warranty conditions
Check how many years of warranty the manufacturer offers – not only for the structure, but also for:
- the outer coating,
- doors, locks and hinges.
Good brands, such as MAFAL, offer longer warranty periods, which is a testament to the quality of their materials.
