Build a greenhouse or cold frame

Dreaming of growing your own and extending the season? A greenhouse or cold frame gives plants a sheltered, warmer environment where you can sow earlier in spring and harvest later into autumn. Here you’ll find our DIY plan for building your own greenhouse – a digital file with a complete shopping list, dimensioned drawing and step-by-step assembly instructions.

Why build your own greenhouse?

Your own greenhouse gives a sheltered environment where heat-loving plants thrive, lets you start the season earlier and grow longer, and gives space to raise seedlings before they move outside. Building it yourself, you decide the size, placement and style – and it usually works out much cheaper than a shop-bought one.

Cold frame or mini greenhouse?

A cold frame is low and used mainly for early sowing and raising seedlings, while a mini greenhouse is a small greenhouse where you reach the plants through doors. Our cold frame / mini greenhouse DIY plan works as both – compact enough to take little space, yet with the feel of a real greenhouse.

What can you grow?

Tomatoes, herbs, vegetables and other plants that like a little extra warmth and shelter. Place the greenhouse free-standing or against a wall, and paint or treat the wood so it suits your garden and lasts longer.
