If you want to build a greenhouse at home, there are many things to consider first. Everything from building materials, style and intended use is worth planning carefully before you start. Here are some of the main things to consider before you build a greenhouse:

What you’re planning to grow

A greenhouse gives you the chance to grow many types of plants you might not be able to support otherwise. The controlled conditions of a greenhouse protect your plants from cold temperatures, pests and other damage. Here are some of the best plants to grow in a greenhouse:

  • Vegetables: Lettuce, broccoli, carrots, spinach, peas, tomatoes, peppers
  • Fruit: Lemons, limes, dates
  • Flowers: Roses, begonias, orchids

What style of greenhouse to build

Before you build a greenhouse, you’ll need to decide what style to build. Here are some of the most popular styles to consider for your greenhouse plans:

  • Attached lean-to greenhouse
  • Standalone greenhouse
  • Window box greenhouse
  • Mini greenhouse
  • Hoop house

What to do if you need a permit

You may need a permit to build a greenhouse on your property. Whether you’re building a standalone structure or adding on to an existing structure, it’s important to do it safely and legally.

Each municipality has different requirements, but permits are commonly required in more densely populated urban areas where there is more risk of accidentally damaging sewer, water or cable lines. In more rural locations, the permit requirements can be more relaxed. Before you build a greenhouse, investigate the necessary permits and apply before you get started.

A DIY greenhouse can be a useful and enjoyable addition to your home. If you’re interested in getting the most out of your gardening, keep these important tips in mind before you begin.
