Are you considering building an attached greenhouse in your backyard? While attached greenhouses have their advantages, it’s important to be aware of the potential drawbacks as well. In this article, we will explore some of the cons of attached greenhouses, such as limited space, temperature control challenges, and potential damage to the main structure. By understanding these potential downsides, you can make an informed decision about whether an attached greenhouse is the right choice for your gardening needs.
1. Limited Space
1.1. Dependency on Existing Structures
One of the major limitations of attached greenhouses is their dependency on existing structures. These structures can include buildings, houses, or garages. The greenhouse is attached to the main building, which means it relies on the available space within the existing structure. This can be a challenge if the space is limited or already occupied by other functions.
1.2. Restriction on Greenhouse Size
Another drawback of attached greenhouses is the restriction on their size. As they are connected to existing structures, the size of the greenhouse is often limited by the available space. This can pose a problem for those who wish to have a larger greenhouse to accommodate a wider variety of plants or to have more space for gardening activities. The limited size can also constrain the overall productivity of the greenhouse.
1.3. Compromise on Crop Selection
The limited space and size of attached greenhouses may also lead to a compromise on crop selection. Certain plants may require specific environmental conditions, such as temperature, humidity, or light exposure, which may not be achieved within the constraints of an attached greenhouse. This can limit the range of crops that can be grown and may hinder the ability to cultivate certain plants that require more specialized conditions.
2. Temperature Control Challenges
2.1. Heat Accumulation
Attached greenhouses often face challenges related to temperature control. One issue is heat accumulation, especially during warmer seasons. As the greenhouse shares a structure with the main building, heat can accumulate within the space, leading to high temperatures that may be detrimental to the plants. This excess heat can stress the plants and can even cause damage or plant death if not properly managed.
2.2. Lack of Ventilation
Ventilation is crucial for maintaining proper airflow and temperature regulation within a greenhouse. However, attached greenhouses may face limitations in terms of ventilation due to their connection with the main building. This can result in inadequate airflow, trapping excess heat and humidity inside the greenhouse. Insufficient ventilation can also contribute to the proliferation of pests and diseases, as well as hinder the growth and health of the plants.
2.3. Non-Uniform Temperature Distribution
Achieving uniform temperature distribution across an attached greenhouse can be challenging. The proximity to the main building and the potential lack of proper insulation can lead to temperature variations within the greenhouse. Certain areas may be hotter or colder than others, affecting plant growth and development. This non-uniform temperature distribution can also make it difficult to create optimal conditions for specific types of plants that require precise temperature ranges for proper growth.
3. Pest and Disease Control
3.1. Easy Access for Pests
Attached greenhouses may be more susceptible to pest infestations due to their connection with the main building. Pests can easily find access to the greenhouse through various entry points, such as doors, windows, or cracks in the structure. This increased accessibility can make pest control more challenging and may require additional efforts to prevent, monitor, and manage infestations effectively.
3.2. Difficulty in Isolation and Treatment
When pests or diseases affect plants within an attached greenhouse, isolating and treating the affected plants can be more complicated compared to standalone greenhouses. In an attached setup, there is a higher risk of pests or diseases spreading to the main building or other attached structures. This makes it crucial to quickly and effectively isolate infected plants, which can be challenging due to limited space and potential constraints in the layout of the greenhouse.
3.3. Increased Risk of Spreading Diseases
The close proximity between the attached greenhouse and the main building can increase the risk of spreading diseases. If a disease outbreak occurs within the greenhouse, there is a higher likelihood of it spreading to the main building and potentially impacting the occupants. This poses a risk not only to the plants but also to the health and well-being of those in the main building, highlighting the importance of disease prevention and control measures in attached greenhouses.
4. Limited Light Exposure
4.1. Structural Shadows
Attached greenhouses may face challenges related to limited light exposure. The proximity to the main building and any surrounding structures can result in structural shadows that block sunlight from reaching certain areas of the greenhouse. This can lead to uneven light distribution, affecting the growth and development of plants that require consistent and adequate sunlight.
4.2. Reduced Sunlight Access
In addition to structural shadows, attached greenhouses may also experience reduced sunlight access due to their orientation or positioning relative to the main building. Factors such as the direction of the sun, nearby tall trees or buildings, or even unfavorable weather conditions can further limit the amount of sunlight that reaches the greenhouse. Insufficient sunlight can hinder photosynthesis, limit plant growth, and impact the overall productivity of the greenhouse.
4.3. Shading of Attached Buildings
While attached greenhouses may face challenges in terms of limited light exposure, there can also be negative effects on the main building itself. Depending on the design and positioning of the greenhouse, it may cast shadows on windows or other areas of the main building, reducing natural light inside. This can negatively affect the occupants’ experience and may require additional artificial lighting to compensate for the decreased natural light.
5. Dependence on the Main Building
5.1. Structural Risks
Attached greenhouses can pose structural risks not only to the greenhouse itself but also to the main building. Any issues or damage to the greenhouse structure can potentially impact the stability and integrity of the main building. This dependence on the main building’s structural integrity carries a higher risk of damage in the event of natural disasters, such as earthquakes or severe storms, which can compromise the safety of both the greenhouse and the attached building.
5.2. Compromised Aesthetics
The presence of an attached greenhouse can significantly impact the aesthetics of the main building. Depending on the design, size, and materials used, the greenhouse may visually clash with the architectural style or overall appearance of the main building. This compromise in aesthetics may be a concern for those who value the visual harmony and cohesive design of their property.
5.3. Limited Flexibility and Adaptability
Attached greenhouses may also limit the flexibility and adaptability of the main building. Once the greenhouse is attached, it becomes a permanent structure that may restrict future modifications or expansions of the main building. This lack of flexibility can be limiting for property owners who envision potential changes or additions to their property in the future. It is important to carefully consider long-term plans and anticipate how an attached greenhouse may impact future building projects.
6. Increased Construction and Maintenance Costs
6.1. Complex Integration
The integration of an attached greenhouse with the main building requires careful planning and execution, which can result in increased construction costs.

This increased noise level can be disruptive to the occupants of the main building, especially in cases where noise sensitivity or concentration is crucial.
7.3. Disturbance for Attached Building Occupants
The presence of an attached greenhouse can introduce disturbances for the occupants of the main building. Depending on the activities being carried out in the greenhouse, occupants may experience disruptions such as odors, humidity, or changes in temperature. These disturbances can be particularly noticeable if the attached greenhouse is located close to living or working spaces, potentially impacting the comfort and well-being of the attached building occupants.
8. Higher Energy Consumption
8.1. Increased Heating and Cooling Needs
Attached greenhouses typically require additional heating and cooling systems to maintain a suitable environment for plant growth. The close connection to the main building means that both spaces can experience fluctuations in temperature, requiring energy-intensive measures such as heating and cooling equipment. This increased energy consumption can lead to higher utility bills and a larger carbon footprint, particularly if the attached greenhouse is not properly insulated or lacks energy-efficient systems.
8.2. Electrical Consumption for Equipment
In addition to heating and cooling needs, attached greenhouses often require electrical equipment for lighting, ventilation, irrigation, and other functions. The operation of these equipment and systems can contribute to higher electrical consumption, further increasing energy demands and costs. It is essential to factor in the energy requirements and efficiency of the equipment when planning an attached greenhouse to minimize the impact on energy consumption.

The dependence on the main building and the potential challenges related to insulation and ventilation can decrease the overall energy efficiency of an attached greenhouse. Inadequate insulation or insufficient ventilation can result in energy losses, making it harder to maintain the desired temperature and humidity levels. These energy inefficiencies can lead to increased energy consumption and diminished sustainability, both economically and environmentally.
9. Structural Limitations
9.1. Weaker Load-Bearing Capacity
The load-bearing capacity of an attached greenhouse may be weaker compared to standalone structures. The connection to the main building and potential modifications to the existing structure can impact the overall strength and stability of the greenhouse. This limitation on load-bearing capacity can restrict the types of plants that can be grown and limit the use of heavier equipment or materials within the greenhouse.
9.2. Limited Height and Space for Vertical Growth
Vertical growth is important for many plants, allowing them to reach their full potential. However, attached greenhouses often have limited height and less available space compared to standalone structures. This lack of vertical space can hinder the growth of certain plants that require ample room for upward growth or the use of trellises and supports. The limited height may also affect the overall aesthetics and functionality of the greenhouse.
9.3. Compromised Structural Integrity
The attachment of a greenhouse to the main building introduces the potential for compromised structural integrity. The connections between the two structures, as well as the potential for water or moisture infiltration through the shared structure, can pose risks to the overall stability of the greenhouse. Proper maintenance and structural assessments are essential to ensure the longevity and safety of both the greenhouse and the attached building.
10. Potential Fungal and Mold Growth
10.1. Moisture Accumulation
Moisture accumulation is a common challenge in greenhouses, and attached greenhouses are no exception. Due to their connection with the main building, there is an increased risk of moisture accumulation within the greenhouse. The presence of moisture can create an environment conducive to fungal and mold growth, leading to potential damage to plants and degrading the overall air quality within the greenhouse.
10.2. Reduced Air Circulation
Proper air circulation is crucial in a greenhouse to maintain a healthy growing environment. However, attached greenhouses may face restrictions on air circulation due to their connection to the main building. Limited airflow can contribute to higher humidity levels, increased likelihood of disease outbreaks, and difficulties in controlling temperature and moisture levels. These factors can impede plant growth and compromise the overall health of the greenhouse ecosystem.
10.3. Greater Susceptibility to Mold and Fungal Infestation
The combination of moisture accumulation and reduced air circulation in attached greenhouses can increase the susceptibility to mold and fungal infestation. Mold and fungi thrive in damp environments, and the presence of excessive moisture can create the ideal conditions for their growth. Once mold and fungi take hold, they can spread rapidly throughout the greenhouse, damaging plants, compromising the structural integrity, and impacting the health of both plants and humans.
In conclusion, attached greenhouses offer certain advantages in terms of convenience and shared resources, but they also come with their fair share of drawbacks. Limited space, temperature control challenges, pest and disease control issues, limited light exposure, dependence on the main building, increased construction and maintenance costs, limited privacy and noise control, higher energy consumption, structural limitations, and the potential for mold and fungal growth are the cons associated with attached greenhouses. It is crucial to carefully consider these drawbacks and evaluate if the benefits outweigh the limitations before embarking on the construction of an attached greenhouse.
