When planning the placement of a greenhouse, the side of the house it faces and other microclimate factors can significantly impact its performance. The orientation of the greenhouse can affect its heating, lighting, and ventilation, ultimately influencing the health and yield of your plants. So, let’s delve into the optimal positioning of a greenhouse relative to your house.
To start, consider the path of the sun throughout the day. The sun’s trajectory varies with seasons and latitude, but understanding its general path can guide your placement decision. In the Northern Hemisphere, the sun’s path is generally from east in the morning to west in the afternoon. Now, let’s explore the greenhouses’ performance based on their orientation.

Sunlight and Greenhouse Positioning: The Northern Hemisphere
The location of the greenhouse in relation to your house can impact the amount and quality of sunlight it receives, which is paramount for plant growth. In the Northern Hemisphere, let’s analyze the effect of positioning a greenhouse on different sides of the house.
To maximize sunlight, you should aim for a south-facing (perfect) or east, west, or north-facing (adequate) position. Keep in mind that the optimal position largely depends on the latitude and the specific plant species you intend to cultivate.
South-Facing Greenhouse
A greenhouse positioned on the southern side of your house can provide the greatest sunlight exposure, especially in the northern hemisphere. During the winters, when daylight hours are shorter, a south-facing greenhouse can help maintain optimal temperatures for your plants. However, it might get too hot during the summer, so proper ventilation is crucial.
Consider planting heat-loving plants, such as tomatoes and peppers, in a south-facing greenhouse. Moreover, adding a shading system can help regulate heat levels during peak summer months. Remember, ‘less is more’ in terms of shading, as you want to maximize sunlight exposure.

East, West, and North-Facing Greenhouses
Greenhouses oriented towards the east or west also receive ample sunlight, though not as much as a south-facing one. An east-facing greenhouse catches the morning sun, which can be optimal for cool-season crops or plants requiring cooler temperatures, like lettuce and spinach. Conversely, a west-facing greenhouse captures the afternoon and evening sun, ideal for warm-season plants.
A north-facing greenhouse gets the least sunlight in the Northern Hemisphere. It’s suitable for shade-tolerant plants or as a shady retreat during hot summer months. However, be prepared for lower temperatures during winter, which might need additional heating.
Other Considerations for Greenhouse Positioning
While sunlight is the primary factor, other elements can influence greenhouse positioning. Wind protection, accessibility, and aesthetics are essential factors to consider.

Wind Protection: Positioning your greenhouse against the house or a wall can offer protection from strong winds. This can be crucial for maintaining optimal internal temperatures, reducing heat loss, and protecting your plants from potential damage. Additionally, consider using windbreaks like trees or shrubs.
Accessibility: Placing your greenhouse near your house or a walkway can make it easier to maintain and access throughout the growing season. Having it close to a water source can also save you time and energy, making tasks like watering more convenient.
Aesthetics: Even functional structures like greenhouses should complement your home’s curb appeal. Positioning it next to attractive plants or features can enhance your overall landscaping.
In conclusion, positioning your greenhouse based on sunlight exposure is crucial for plant health and growth. However, don’t overlook other factors like wind protection, accessibility, and aesthetics. With careful planning, you can create an idiot-proof greenhouse that’s not only functional but also an attractive addition to your home. Start by assessing your microclimate and specific plant needs, then choose the best side of your house for your greenhouse. Happy green housing!
