A greenhouse is a structure with a transparent roof and transparent walls, usually made of glass. They house plants and provide them with a controlled growth environment. They are suitable for plants that need to adjust the climatic conditions, because the inside of the greenhouse exposed to the sun is much warmer than the outside. Greenhouses make year-round gardening possible.

The greenhouse is as large as a shed or as large as an industrial building. Most hardware stores sell greenhouse construction kits, allowing you to build a standard kit yourself. However, if you prefer something bigger and more personalized, please consider hiring a professional. The cost of building one is between US$2,500 and US$25,000, with an average of approximately US$15,000.

The cost of building a greenhouse will increase as its square footage increases. In other words, as the overall square foot increases, the price per square foot will actually fall. It still makes the total higher, but the cost increase will not increase exponentially.

The average cost of a standard medium-sized greenhouse is $25 per square foot. Large commercial greenhouses consist of plastic or fiberglass on a steel frame, which may or may not include ventilation and ducts, and cost between US$2 and US$4 per square foot.

The greenhouse is a simple structure consisting of a frame, siding and floor. The materials of these components vary, but can include wood, steel, glass, concrete, and plastic.

The frame of the greenhouse is the supporting system of the structure. Generally, the greenhouse frame is made of strong wood or steel, which can withstand the test of various factors. The cost per linear foot of a wooden frame is approximately $1, while the cost per linear foot of steel is $2.50.

Siding is another important feature of greenhouses. It can protect plants from natural factors and allow a lot of sunlight to shine on them. Glass siding is common in greenhouses and costs $2.50 per square foot. However, glass is heavy, so you may need a strong steel frame to support it. Polyethylene and glass fiber are low-cost alternatives.

Although the greenhouse can be operated without a suitable floor, the floor does have its benefits. It helps insulate the structure while preventing weeds from growing and preventing pests from entering and destroying plants. Rolled rubber flooring is a common choice for greenhouse flooring, costing $2 per square foot. Concrete, stone, brick and even mulch are other greenhouse floor options. No matter what material you choose, it must provide some sort of drainage function.

There are several types and styles of greenhouses, each with its own advantages and disadvantages. The climate of your area will help determine which type is best for you. Costs vary greatly, but the following are examples of costs for common greenhouse types:

The cost per square foot is between US$5 and US$10, and the annular greenhouse is made up of multiple semi-circular rings in succession. Most of the hoop is above the ground, and its end is buried in the soil. Usually, the hoop is covered with a layer of plastic. roof

Rooftop greenhouses are usually located on top of tall flat roof buildings in urban areas. Their prices range from US$10 to US$25 per square foot.

A geodesic or domed greenhouse is a circular structure with a domed top. They can be made from a variety of materials, including glass and plastic, and cost between $10 and $25 per square foot. Although these types of greenhouses have a relatively small footprint, they can hold many plants due to their size. This makes them ideal for small spaces.

One of the most common types of greenhouses is the A-frame. It has a high roof that slopes down to the ground, forming an A shape. This type of greenhouse works well in areas with heavy snowfall, because the sloping roof allows snow to slide down without accumulating and damaging it. The cost of an A-frame greenhouse ranges from US$25 to US$35 per square foot.

The glass is crystal clear and can penetrate a lot of sunlight while remaining durable. Although glass is an effective insulator, it can actually burn plants. It does not diffuse sunlight, but amplifies it. To solve this problem, use grids to protect plants.

If you have some building knowledge and a well-stocked toolbox, you may be able to build a greenhouse from scratch. Small greenhouses, especially those with off-the-shelf kits, can be built on weekends, but larger greenhouses may take several weeks. Hiring professionals to help you build may be more efficient. In addition, the experience of professionals means that your greenhouse will be of high quality.

It takes two to three days to assemble a standard greenhouse by yourself. It may take a weekend to build a small greenhouse, while a larger one may take several weeks to complete.

If you buy a standard greenhouse kit without frills, its cost may be lower than the cost of building a greenhouse from scratch. However, if you want a customized large greenhouse, it is more cost-effective to build it yourself.

Unless the site where you build the greenhouse is completely horizontal and there are no shrubs, you need to landscape the area. The cost of excavation and landscaping will vary depending on the condition of the land, but the average cost ranges from US$3 to US$15 or more per square foot.
