Everything you need to know about greenhouses in the Nordic climate
When does a greenhouse require a building permit?
- If the greenhouse is larger than 50 square meters.
- If it is built closer than 1 meter to the property boundary without the neighbor’s consent.
- If it has a ridge height exceeding 3 meters.
- If it violates local zoning plans, building lines, or similar regulations. What should you do before setting up a greenhouse? Even if your greenhouse falls within the limits that do not require a permit, it is important to:
- Check zoning plans and local regulations: Your municipality may have specific rules affecting what you can build and where.
- Talk to neighbors: Even if a permit isn’t required, it is often a good idea to inform your neighbors, especially if the greenhouse is to be placed near the property line.
- Contact the municipality if in doubt: If you are unsure whether your project requires a permit, you can always contact the municipality for guidance.
Why buy a greenhouse?
Extending the growing season: With a greenhouse, you can start growing earlier in the spring and continue well into the autumn, giving you more time to cultivate a wide range of plants. Growing environment: The greenhouse protects your plants from unpredictable weather, pests, and diseases, while allowing you to control temperature, humidity, and light conditions for optimal growth. Self-sufficiency: A greenhouse makes it possible to grow fresh vegetables, herbs, and flowers year-round, which can reduce food costs and provide you with healthier, more flavorful produce. Sustainable gardening: By growing your own food, you reduce reliance on transported goods, contributing to a smaller carbon footprint. You can also grow organically and reduce the use of chemicals. Hobby and well-being: Gardening in a greenhouse can be a relaxing and satisfying activity that promotes mental well-being. It also offers an opportunity to learn more about plants and cultivation, and can become a rewarding hobby.
What is a greenhouse?
A greenhouse is a structure, often made of glass or plastic, that creates a controlled environment for growing plants. It protects against unpredictable weather conditions such as cold, rain, and wind, and extends the growing season. Greenhouses can be used to grow vegetables, fruit, herbs, and flowers regardless of the outdoor climate, allowing for cultivation during much of the year.
How to grow organically?
01. Use organic soil and compost
Start by using high-quality organic soil and adding compost to improve soil structure and provide natural nutrients. Avoid synthetic fertilizers and instead use alternatives like compost tea or animal manure.
02. Rotate crops
Change the location of different plants from year to year to avoid soil depletion and reduce the risk of pests and diseases. This helps maintain soil fertility and supports healthy growth.
03. Use natural pest control
Avoid chemical pesticides. Instead, use natural methods such as beneficial insects—like ladybugs—or homemade solutions like neem oil to control pests.
04. Choose resistant plant varieties
Select plant varieties that are naturally resistant to common diseases and pests in your area. This reduces the need for pesticides and increases the chances of a healthy crop.
05. Save water with efficient watering
Use water-saving techniques, such as drip irrigation or watering early in the morning, to reduce evaporation. Collect rainwater for use in the garden, which also reduces the consumption of municipal water.

Frequently Asked Questions

What should I look for when buying a greenhouse?
When purchasing a greenhouse for use in a Nordic climate, it is important to consider several factors to ensure it can withstand challenging weather conditions and provide optimal growing conditions. First and foremost, look for a greenhouse with a solid structure. An aluminum frame is ideal, as the material is robust and resistant to both snow and wind. The glazing should consist of at least 4 mm tempered glass or polycarbonate; if you choose polycarbonate, it must be UV-resistant. A solid warranty is also a minimum requirement. Finally, durability and maintenance are key factors. Choose a greenhouse that requires minimal maintenance and is made from materials resistant to rust and corrosion. Also, ensure that all parts and fittings are of high quality so that the greenhouse remains sturdy during the harsh winter conditions of the Nordic region. By considering these aspects, you can choose a greenhouse that is well-suited to the Nordic climate and will provide years of enjoyment and abundant harvests.
How large a greenhouse do I need?
The size of the greenhouse should suit your needs and the available space in your garden. Consider whether you also want to use it as an outdoor living space for family and friends. If you wish to combine plants with furniture, you should probably opt for a greenhouse larger than 12 m². It is also important to consider how much sunlight the area receives, as sufficient light is crucial for plant growth. The greenhouse’s placement relative to the prevailing wind direction should also be taken into account; it is wise to position the greenhouse in a spot that offers maximum protection against strong winds.
Automatic watering / vent openers
Automatic vent openers and watering systems are smart solutions that help maintain optimal growing conditions for your plants. Automatic vent openers ensure the greenhouse is ventilated when temperatures rise too high, preventing overheating and promoting good airflow. This reduces the risk of pests, mold, and other issues associated with poor ventilation. Automatic watering systems ensure plants receive a consistent and appropriate amount of water, which is vital for healthy growth and prevents both drying out and overwatering. These automatic systems save time and make it easier to maintain ideal conditions in the greenhouse, even when you are not present.
How to winterize a greenhouse?
01. Cleaning and removing plant debris
Clear out all old plants, withered leaves, and debris to prevent pests and mold. Wash glass or plastic panels thoroughly to ensure maximum light penetration during the winter.
02. Check the structure and seal joints
Inspect the frame for damage or loose parts, and tighten any screws. Ensure that all joints, doors, and windows are sealed tight to prevent cold air from entering.
03. Insulate with bubble wrap
Attach bubble wrap to the inside of the greenhouse panels for extra insulation. This helps retain heat and protects the plants from the cold.
04. Heating
If possible, applying a little gentle heat on the coldest days is recommended—for example, using a small fan heater or another heat source.
05. Remove snow from the roof regularly
If you live in an area with heavy snowfall, you must regularly clear snow from the greenhouse roof to avoid overloading the structure. Consider installing temporary supports for added safety.

Can I use the greenhouse for more than just growing plants?
Yes, you can use a greenhouse as a garden room or outdoor living space; it’s a great way to extend the use of your garden. However, keep in mind that greenhouses are not watertight structures; you will encounter both condensation and humidity. Choose a greenhouse large enough to accommodate furniture and plants, with a design that complements your garden. Quality materials—such as aluminum or galvanized steel for the frame, and tempered glass or polycarbonate for the walls—offer both aesthetic appeal and functionality. Good ventilation and heating options are essential for year-round use. Consider installing heating elements or underfloor heating, and ensure there are ways to regulate the temperature. Furnish the space with weather-resistant furniture and plants to create a cozy environment. Lighting can also help create a pleasant atmosphere in the evening. The greenhouse can serve as a place to relax, entertain guests, or pursue hobbies. With regular maintenance—such as cleaning and pest control—your greenhouse can become an inviting garden oasis that you can enjoy all year round.
5 tips for cleaning your greenhouse
01. Clean glass or plastic panels thoroughly
Wash both the inside and outside of the greenhouse’s glass or plastic panels at least once a year. Use a mild soap or vinegar solution to remove dirt, algae, and mold that could block sunlight and hinder plant growth.
02. Remove all plant material
Before you start washing, remove all plants, loose pots, and other equipment from the greenhouse. This gives you full access to all surfaces and helps prevent dirt and cleaning agents from damaging the plants.
03. Disinfect the surfaces
After cleaning, use a mild disinfectant to kill any disease spores, pests, or mold. Make sure to thoroughly treat corners, joints, and other hard-to-reach areas.
04. Clean base plates and drainage systems
Remove any debris and soil that has accumulated on the base plate or in the drainage systems. This prevents moisture buildup that can lead to mold growth and avoids blockages that could hinder effective drainage.
05. Check and clean vents
Clean the vents to ensure good airflow. Remove dirt, dust, and any obstructions to prevent the ventilation system from becoming inefficient, which could lead to moisture problems inside the greenhouse.

Can I assemble the greenhouse myself?
Assembling a greenhouse should be a manageable task for a family, with help from friends and relatives if needed. Assembly time and difficulty vary depending on the model and supplier. It is important to set aside enough time and be patient. We recommend that at least two people work together to assemble a greenhouse. Remember that the greenhouse also needs to be anchored and sealed—for example, using a product like Tec7.
Assembly assistance
If you feel you lack the time or inclination to tackle the assembly job yourself—or if, for other reasons, you are unable to do it on your own—we recommend hiring a professional. At Fasadenor, we partner with “Drivhusgutta,” who can handle the assembly work for our customers.
Which foundation should I choose?
When choosing a foundation for a greenhouse in Norway, it is important to select a solution that can withstand varying climatic conditions, including frost, snow, and strong winds. Here are some common types of foundations well-suited for greenhouses in Norway:
Concrete foundation
Advantages: A concrete foundation offers superior stability and durability, especially in areas prone to high winds or heavy snow. It is frost-resistant and provides a solid base that prevents the greenhouse from shifting or becoming uneven over time. Disadvantages: Concrete foundations are more time-consuming and costly to install compared to other options. They also require precise measurements and planning.
Pressure-treated timber beam foundation
Advantages: Pressure-treated beams are a popular option that provides good support and is more economical than concrete. They are resistant to rot and moisture, making them a great choice for the Norwegian climate. The beams can be easily adjusted to ensure the greenhouse is level. Disadvantages: Over time, wood can deteriorate—even when pressure-treated—requiring maintenance and potential replacement.
Ground spikes (screws or ground anchors)
Advantages: Ground spikes or anchors offer a quick and easy way to secure the greenhouse to the ground without the need for digging or pouring concrete. This is a flexible solution adaptable to various terrain types, providing good stability in areas with moderate weather conditions. Disadvantages: This type of foundation offers less stability than concrete, especially in areas with high winds or uneven terrain. It may also be less durable in areas with heavy snow loads.
Concrete block pier foundation
Advantages: Pier foundations use concrete blocks placed under the corners and along the sides of the greenhouse. This creates a solid base that is easier to install than a full concrete foundation. It provides good stability and protects against frost heave. Disadvantages: Requires more preparation than simpler options like ground anchors or gravel, yet does not offer quite as much stability as a continuous concrete foundation.
Wooden deck
Using a wooden deck as a greenhouse foundation involves using pressure-treated beams to create a framework on the ground. These beams form a solid, stable base to which the greenhouse can be anchored. It is a great option if you plan to have tables, chairs, or other furniture inside the greenhouse. The beams are resistant to rot and moisture, making them suitable for the Nordic climate. This foundation is easier and faster to install than concrete; it provides good stability and allows for adjustments to ensure the greenhouse is level. It is a popular choice for small to medium-sized greenhouses.
