Regularly reapplying the finish as recommended by the manufacturer is essential for long-term preservation. Staining or painting your structures not only enhances their aesthetic appeal but also adds an extra layer of protection against the elements.

Even more so among eco-conscious DIYers, sourcing sustainable or reclaimed wood can be a winning choice; it promises a lower environmental impact without sacrificing structural integrity or visual appeal.

Choosing the Ideal Location for Your Garden Structure

Selecting the right location for your garden structure, whether it’s a veranda, pergola, shed, or greenhouse, is a pivotal decision that can significantly impact its functionality and overall enjoyment. Several factors come into play when determining the optimal placement, and innovative design solutions can further enhance your experience. Here are some examples of how to consider these elements:

Sun’s Path and Seasonal Variations

Understanding how the sun’s path changes throughout the seasons is crucial for choosing the location of your garden structure. During the design phase, consider the following:

Orientation

South-facing structures generally receive the most sunlight, making them ideal for maximising natural light and solar heat gain. East-facing structures will enjoy morning sun, while west-facing ones will bask in the afternoon sun. Depending on the type of structure this information is vital.

If you are building a garden room, summer house or shed that needs to stay cool in the summer months, consider some of the following:

• Eaves Height: The eaves height of your structure can affect the amount of sunlight that penetrates its interior. Higher eaves allow for more light to enter, while lower eaves may provide shading during peak sun hours.
• Window Sizes and Placement: If your garden structure features windows, their size and placement can determine the amount of natural light that filters in. Larger windows on the sunnier side can maximize light, while smaller or strategically placed windows can control heat and glare.
• Shutters for Window Control: Adding shutters to the outside of windows that receive direct sunlight can provide you with precise control over the amount of light and heat entering your garden structure. This feature allows you to adapt to changing weather conditions and the sun’s intensity.
• Suitable Insulation: With the correct size and type of insulation you will be able to keep your garden room cool during the summer. Check out my extensive guide on how to insulate your garden room. When summer rolls in with its long days of strong sunlight, confirm if another round of UV-resistant coating becomes necessary.

Verandas and pergolas will also benefit from having flexible sun shades installed. Thoughtful design can allow for the mounting of sun shades or awnings in different locations to accommodate the sun’s movement throughout the year. We installed multiple mounting points for our sun shade that can easily be adjusted throughout the year to accommodate the changing sun position in the sky.

For greenhouse or solariums ventilation is key. Whilst you’ll want these building to be in direct sunlight for optimal growing, you also need to limit internal temperatures. Consider adding air vents at both the top and bottom of the structure. This design allows for efficient airflow, preventing overheating during the day and maintaining stable temperatures for optimal plant growth.

Natural Elements

• Tree Cover Integration: Your garden structure’s placement can take advantage of existing trees. For example, positioning a pergola strategically to interact with a nearby tree’s canopy can create a beautiful interplay of shade and sunlight, enhancing the overall ambiance.
• Elevation for Views: Placing a garden room or gazebo on an elevated area of your property can provide breathtaking views of the surrounding landscape. This elevation not only offers visual appeal but also captures cooling breezes, making your outdoor space more comfortable.

Using your gardens landscape to plan structures and foliage placement is key to a successful and functionality for your garden structures. You can also look to cultivate the sun’s energy with solar which can be incorporated into your garden room, shed or any other suitable structure. Here a quick look at solar placement for additional energy.

Optimising Solar Panel Placement for Garden Structures

One sustainable and energy-efficient feature to consider when designing your south-facing garden structure, such as a garden room or shed, is the integration of solar panels. Solar panels can help you harness the abundant sunlight to generate renewable energy for various purposes. Here are some key considerations for optimising solar panel placement:

1. Roof Orientation: When constructing a garden room or shed, orienting the roof to face south can maximize the solar panel’s exposure to sunlight throughout the day. South-facing roofs receive the most direct sunlight, making them an ideal location for solar panel installation.
2. Tilt Angle: The optimal tilt angle for solar panels depends on your geographic location. Generally, positioning the panels at an angle close to your latitude can help maximize energy capture. However, adjustable mounts can be used to fine-tune the angle for the best results.
3. Shade Avoidance: Ensure that the chosen location for your garden structure and solar panels is free from obstructions that may cast shadows on the panels. Even partial shading can significantly reduce energy production, so select a spot that remains in full sunlight.
4. Proximity to Electrical System: Consider the proximity of your garden structure to your home’s electrical system. The closer it is to your electrical panel, the more efficient and cost-effective the installation will be.

By strategically placing solar panels on your south-facing garden structure and orienting it to capture the sun’s energy efficiently, you can not only reduce your carbon footprint but also potentially generate surplus electricity that can be fed back into the grid or used to power your garden room or shed, making it a sustainable and eco-friendly addition to your property.
