Design features and construction of a 3x6 greenhouse

Advantages and disadvantages

If you're planning to build a 6x3m greenhouse on your garden plot, you need to understand the advantages and disadvantages of this type of structure before you begin construction.

A greenhouse with such dimensions has the following advantages:

• easy frame assembly;
• Any suitable materials can be used for cladding;
• Excellent strength. The structure can withstand not only significant wind loads but also heavy snow loads. Therefore, in areas with moderate precipitation, such structures are often erected without the additional installation of reinforced arches and braces;
• long service life of the greenhouse;
• The small size allows for good heat accumulation, which makes it possible to easily maintain the microclimate necessary for planting inside the structure;
• good light transmittance of the building;
• affordable cost of construction;
• easy greenhouse maintenance.

Despite such an impressive list of advantages, this type of greenhouse has two disadvantages.

The first is that the 3x6 m greenhouse layout requires the walls to be raised to a height of 2 m. Because of this, the arched profiles will have to be significantly bent when assembling the roof frame. This work is difficult to accomplish without specialized equipment, which entails additional costs.

The second obvious drawback of this design is its small size. Because of this, it's not always clear how to arrange the beds in a 3x6 m greenhouse. For example, to create three beds, the aisles would have to be significantly narrowed, making planting a bit more difficult and inconvenient.

It's worth noting that the structure's size is also its advantage. Such small greenhouses can fit into almost any garden or vegetable patch.

Greenhouse layout

Because a 6x3 m greenhouse is small, it's essential to carefully plan its interior space before construction. To do this, draw a diagram of the structure and determine the most efficient arrangement of the beds within.

The diagram should reflect the following points:

• Greenhouse parameters: height, width, and length. For convenience, the height is taken to be 2–2.5 m. The length of this structure is 6 m, and the width is only 3 m;
• Construction type. These greenhouses are assembled from frame elements and can be installed either on a specially prepared foundation or directly in the ground. The former option is considered more advantageous, as it provides additional strength to the structure and minimizes heat loss.
• Placement of ventilation vents. It's best to install structural ventilation devices under the roof. However, if this isn't possible, vents are mounted in the walls. Effective ventilation requires a door and 1-2 windows;
• Interior design of a 3 x 6 meter greenhouse. Here, you need to specify the size of the beds and their placement within the greenhouse.

A properly drawn plan will help you determine how much material will be needed for construction, where to best arrange the beds to plant as many plants as possible, and the sequence of work.

How much will the construction cost?

Using a greenhouse diagram, you can calculate the cost of the entire structure. Since you'll be constructing the structure yourself, you'll only need to spend money on materials. The final cost depends on the materials used. Naturally, a polycarbonate greenhouse will cost more than a film structure. However, it will be much stronger and more durable.

Because the structure can be assembled from a variety of materials, it is difficult to calculate the exact cost of construction.

Selection of material

A 3x6 m greenhouse is assembled from a frame, which is then covered with covering material. The frame can be made from the following materials:

• Metal profiles or pipes. The advantage here is high strength, but the disadvantage is a tendency to corrode without special protection;
• Wooden beams. This material is easier to work with than metal, but wood is less durable. Even specially treated beams won't match the service life of metal structures;
• Plastic pipes. This material is also easy to install, but less durable.

You can make a greenhouse lining of this type using the following materials:

• Polycarbonate. This material is durable. It retains heat well and transmits light, which is essential for creating the right microclimate for planting;
• Film. The cheapest cladding option. Today, there are a wide variety of films specifically designed for greenhouse cladding. The main drawback of film is that it can be easily damaged.

Each gardener decides for themselves what materials to use for their greenhouse, based on their preferences and budget. However, the interior layout is not affected by the type of material used.

Step-by-step instructions

The assembly of a greenhouse with dimensions of 3x6 m is carried out as follows:

• First, a place is chosen. It must be level;
• Next, it needs to be arranged: cleared and all the garbage removed;
• If a foundation is needed, a trench is dug and filled with concrete. A strip foundation is best;
• Next, the frame is erected. It is secured to the foundation or ground. When erecting walls, door or window openings must be immediately installed;
• Once the wall frame is in place, the roof is assembled.

Once the frame is complete, it is covered with either film or polycarbonate sheets. All joints are sealed with a sealant or reinforced with special tape. This will prevent drafts inside the structure and minimize heat loss.

When everything is ready, the previously drawn diagram of the beds in the 3x6 m greenhouse is used, and the internal space of the structure is arranged for planting plants.

Interior design

How do you set up a polycarbonate or film greenhouse with dimensions of 3x6 m, you ask? For a rational design, consider the following points:

• the dimensions of the beds in the greenhouse are 3x6 m;
• their number;
• width of passages.

It would be wise to place long beds along the walls of a 3 x 6 meter greenhouse. These will be used for planting tomatoes and cucumbers. Short beds, spaced widthwise, are suitable for growing peppers and eggplants. Any crops can be grown in the center. This will create three long beds and one short one.

A 3x6 meter greenhouse has many advantages and few disadvantages. However, the interior design of such a structure must be well-designed to accommodate the simultaneous cultivation of several different crops.
