The Shed-Greenhouse Combination

One of the main issues that prevent people from buying greenhouses is that they are expensive and take up much space. That is especially true if you already have a garden shed.

But converting your shed into a mini-greenhouse solves both of these issues! That’s not to say there aren’t some costs, however. That is why we have created this how-to guide for you to follow!

How-To Guide

Now that we have got your imagination running wild with the idea of your new mini-greenhouse, let’s take a look at some of the steps you need to take to convert your shed into a greenhouse successfully.

It is worth saying at this point that if you do not feel comfortable using a hammer, we highly recommend you ask for some help.

Plan Ahead

Firstly, you need to make one big decision. Do you want a mixed shed and mini-greenhouse or a full greenhouse?

If you believe that you have a large enough shed to work as a shed or mini-greenhouse, then why not try and have both.

If your shed is too small, then you may want to go for a larger one or a complete greenhouse.

What Type of Glazing do You Want?

There are so many glazing options to choose from. Do you require polycarbonate? Horticultural glass? Toughened glass?

We usually recommend you go for fiberglass due to its strength, ease of handling, and lightweight. Not only that, but it overlaps and stops moisture from getting in. 

The Placement

Once that is decided, it is time to choose where you want your mini-greenhouse to go. In an ideal world, you will want to make sure that your greenhouse faces the rising sun. That way, the greenhouse will get warmer throughout the day and will remain warmer overnight.

The Structure

Next, let’s consider the structure of your mini-greenhouse. For starters, you should be sure that your shed is in relatively good condition.

Ensure you have enough room to get to critical areas to maintain your mini-greenhouse. Once you are confident in where you want your mini-greenhouse to go, you can move on to the final step.

The Construction

And that final step is construction! It is now time to build your mini-greenhouse.

Start by taking off the wooden panels and replacing them with fiberglass. This could be the whole roof and all the sides, or just certain sections.

Add support across the rafters or install wall studs for attaching the glass panels if you need to.

Mark and cut your glass panels using a saw blade.

Connect your glass panels to the backing panels and then drill together.

Hammer the backing boards onto your wall studs or rafters.

To finish, screw your panels into the backing panels.

The Takeaway

There you have it! All of the tools that you need to build your mini-greenhouse! The only thing left to do is plant your flowers and plants and watch them grow and prosper in your homemade glasshouse. And if you’re still in doubt whether you can turn a shed into a greenhouse, you can check one of the small greenhouses that don’t take up much space and are budget-friendly.
