Special Features and Uses

A custom-made garden house can have various special features and uses, making it a versatile addition to your garden and living space.

Garden Rooms and Garden Offices

A garden room can serve as extra living space where you can relax or entertain guests. These types of garden houses are ideal for use as a guesthouse, creating a comfortable space with furniture and amenities such as a small kitchen and bathroom. This provides a private, self-contained area for your guests.

A garden office offers a quiet workspace free from the distractions of home. This type of garden house can be equipped with insulation, electricity, and internet connectivity, creating a professional workspace that meets all your needs. With a comfortable office chair, good lighting, and plenty of storage, you can work productively in your own garden.

Garden Houses as Storage and Hobby Spaces

A garden house can also be used as storage space, which is useful for storing garden tools, bicycles, and seasonal items. By adding shelves and storage boxes, you can keep everything organized and accessible. This helps keep your main building tidy and provides extra space for your belongings.

Another popular use is transforming a garden house into a hobby room. Whether you enjoy painting, crafting, or woodworking, a hobby room gives you the freedom to explore your creativity. With a good ventilation system, enough work tables, and storage for materials, you can take your hobby to the next level without the limitations of indoor space.

Permits and Regulations for a Garden House

When building a garden house, you must consider permits and building regulations. Whether you build a custom garden house or use a kit, you need to know when a permit is required and how to apply for it at the local municipality.

When is a Permit Needed?

A permit is required when the garden house exceeds certain dimensions. For example, if your garden house is larger than 30m² or higher than 3 meters, a permit is generally required. Additionally, a garden house placed closer than 1 meter to the property line may also require a permit. If you place it in the front yard or on the side of your house, stricter rules apply. Even if you stay within these dimensions, you still need to comply with the Building Act, which means you may still need building plans and structural calculations, such as for the stability of the structure.

How to Apply for a Building Permit at the Municipality

Applying for a building permit begins with gathering all the necessary documents, such as:

• Building Plans: These show what the garden house will look like.
• Structural Calculations: Proof that the garden house is safe and stable.
• Location Plans: These show the exact location on your property.

Visit your municipality's website, where you can usually submit the application digitally. The process may take 6 to 8 weeks, depending on the municipality. Keep in mind that additional information may sometimes be requested. Be prepared for potential fees, typically around 2% of the construction costs, to process your permit application.

These steps help you obtain the building permit smoothly and ensure your project complies with all legal requirements.

The Foundation of a Garden House

A solid foundation is essential for the stability and lifespan of your garden house. Here you’ll learn what is needed for a strong foundation and the different types of foundations you can use.

Requirements for a Strong Foundation

For a strong foundation, there are several basic requirements. First, the ground on which you build must be stable. This means properly preparing the ground by digging and leveling it if necessary.

Additionally, it’s important that the foundation is level. This prevents tilting and ensures that your garden house stays upright. A spirit level and a good measuring stick can help with this.

The thickness and type of material also play a role. Choose strong material such as concrete, which has sufficient load-bearing capacity to support the garden house.

Types of Foundations for a Garden House

There are different types of foundations you can use for your garden house. A common option is the concrete slab. This is a sturdy and stable choice that compacts and levels the ground well.

Another option is the use of concrete strips. These are often used for larger garden houses and ensure even weight distribution. Concrete strips are useful when dealing with uneven ground.

You can also choose concrete foundation blocks. This is a simple method that is easy to do yourself. These blocks can be laid level and provide a stable base.

Each foundation has its pros and cons. Make sure to choose the right one based on your specific situation and the characteristics of your soil.

Designing a Custom Garden House

Designing a custom garden house requires careful planning and decisions about size, style, materials, and finishing.

Determining Size and Style

The right size and style are crucial for the design of your garden house. Think about how much space you need. Measure the available area carefully. Also, consider the height of the garden house, especially if you need lots of storage space or are considering a sleeping loft.

Choosing Materials and Finishing Options

When choosing materials for your garden house, you have several options, each with unique advantages and disadvantages. The material not only determines the aesthetic but also the durability and maintenance of your garden house.

Douglas Wood

• Skills Required: Although simpler, assembling the kit still requires basic construction skills.

Custom Garden Houses: When is it the Best Choice?

A custom garden house offers complete design freedom. You can tailor the garden house to your specific needs and preferences.

Advantages:

• Design Freedom: You can customize everything, from the dimensions to the type of roof covering and the placement of windows and doors.
• Unique Appearance: A custom garden house can be perfectly matched to the style of your home and garden, creating a harmonious look.

Considerations:

• Cost: Custom options are often more expensive and can significantly impact your budget.
• Longer Delivery Time: Designing and manufacturing a custom garden house takes more time, leading to a longer delivery time.

Building a Garden House

Building a garden house starts with thorough planning and preparation. First, a solid foundation is laid, essential for the stability and durability of the garden house. The contractor ensures that the foundation is level and suitable for the type of ground on which the garden house is built.

Next, the walls are erected. The contractor starts by securing the corner posts and wall panels according to the garden house design. Once the walls are firmly in place, the roof structure is added, often with wooden beams as supports. The roof is finished with a chosen material, such as tiles or bitumen, depending on your preference and the local weather conditions.

The doors and windows are custom-installed to ensure adequate light and ventilation. The installation team carefully checks that the structure is sturdy and level, ensuring there are no issues with stability or drainage.

All necessary tools and materials, including wood panels, screws, nails, and roofing materials, are provided by installers. This ensures the project proceeds efficiently and delivers professional results without you needing to worry about technical details.

Maintenance and Durability of Garden Houses

Regular maintenance and high-quality materials can significantly extend the lifespan of your garden house. Here are the most important tips and steps to keep your garden house durable.

The Importance of Good Maintenance

Proper maintenance of your garden house begins with regular inspections. Check the wood for cracks and signs of rot. Whether you have a wooden or plastic garden house, regular inspections are crucial. Wooden garden houses may benefit from an annual treatment with stain or paint to protect against moisture and UV rays.

Plastic garden houses also require maintenance, although less intensively. Regular cleaning with mild soap and water is often sufficient. Don't forget to keep the gutters clear of leaves and debris to ensure proper water drainage. This helps prevent water damage, increasing the durability of your garden house.

Tips for Longevity

To extend the lifespan of your garden house, consider impregnating the wooden structure. This process makes the wood resistant to mold and insects. Insulation can also be a smart investment. Well-insulated garden houses are better protected against extreme weather conditions and suffer less from condensation.

Use sturdy materials for the foundation. A poor foundation can cause your garden house to sink, leading to structural damage. High-quality doors and windows also contribute to the overall lifespan of the garden house.
