Grow upwards, save space
A tall coldframe, sometimes called a patio greenhouse or mini greenhouse, gives you the protection of a greenhouse in a fraction of the space. It stands against a wall or fence, which shelters it from strong winds and keeps it warm, and is tall enough for crops that outgrow a standard coldframe, such as tomatoes, peppers and aubergines. It is just as good for raising seedlings in spring.
Every tall coldframe is made entirely from Western Red Cedar, joined with precise mortice and tenon joints, with a 15mm cedar-panelled back. Two sliding front doors give easy access, and up to four opening roof lids lift off easily for ventilation. All glazing is 4mm toughened safety glass.
One wide (500mm) and one narrow (300mm) adjustable shelf come as standard, and you can add more.
Useful all year round
Spring
Raise seedlings on the shelves and harden off young plants before planting out.
Summer
Grow tomatoes, peppers, aubergines and cucumbers in a warm, sheltered space.
Autumn
Ripen the last chillies and tomatoes, and root cuttings.
Winter
Protect tender plants such as pelargoniums, citrus and young perennials from frost and rain.

Which size do I need?
- Width: a 3ft or 4ft model suits a small patio or a corner of your greenhouse; 6ft and 8ft give room for a full row of tomatoes or peppers.
- Height: a shorter model suits most crops and seedlings; choose a taller one for the tallest tomato varieties and more shelf levels.
- Position: pick a sunny wall or fence that shelters it from strong winds.
We make every tall coldframe in our own workshop, so we can also build bespoke sizes on request.
