Clear winner

I like this Victoria Tall Wall greenhouse by Forest – it could be just the job if you yearn for such a structure but lack space and/or funds for a full-size one. Having a back panel means it can be stood anywhere (not just by a wall) and its fold-down centre shelves make the inside space flexible. It is made of pressure-treated timber with a 15-year anti-rot guarantee and has acrylic windows. Measuring 196cm high x 147cm wide x 74cm deep, it costs £389.99 (flat-pack, unpainted) including delivery (0333 003 0026; forestgarden.co.uk).
