Greenhouses are now considered a way of life and hobby from the basic garden under glass concept. Most greenhouses are either freestanding or attached to an existing structure e.g. house or shed. Greenhouses can become the focal point of any garden or an extension to any home as the designs are becoming more architecturally pleasing.
Attaching a greenhouse to an existing building can provide better access in harsh weather conditions for plants needing a lot of attention. Some estate agents will even consider adding the square footage of an attached greenhouse to the total square footage of the existing house to increase real estate value if properly planned.
If you want to escape to your garden, than a freestanding greenhouse is a great hideaway. Freestanding greenhouses can have their own unique design and therefore enhance any garden adding another feature.
Some helpful tips while designing or choosing your greenhouse:
- Shade – it is important to place the greenhouse away from nearby shade as in winter they will block what little sunlight there is. Debris from a tree too close can make the roof dirty which would require cleaning.
- Weather – Remember when plotting were to put the greenhouse of wind and severe weather. Winds allow cooling and ventilation during warmer periods however; this could create a lot of heat loss in colder seasons. Placing the greenhouse at the bottom of a hill or dip will help shield it from some of the elements; however it may be more prone to moisture or frost.
- Roof – It is important when attaching a greenhouse to an existing building that the roof slope is considered. This could be damaged in winter due to sliding snow or tiles. Extra gutters, ice breaks, or an impact resistant roof glazing e.g. polycarbonate will help prevent damage being done.
- Sunlight – If the greenhouse is attached to an existing building it is important to place it so the delicate plants or seedlings can not be harmed by direct or excessive sunlight. Sunlight penetrates at is optimum when perpendicular to the glazing of the greenhouse. A free standing greenhouse’s plot is not as important as it receives light from all sides. South, southeast, or east facing attached greenhouses will provide the greatest light exposure. However western exposure also provides adequate light. The only time northern facing greenhouses are recommended is for plants with low light requirements or if grow lights are utilized.
- Important! – Build the greenhouse on a solid foundation. If the foundation is unstable, the structure may be prone to shifting, or frame and glazing breaking.
Hope these tips help you when planning a greenhouse; remember there are many materials and designs which can be used. Greenhouses are a great way to fully enjoy gardening all year round and are also great with experimenting.
