Granddaughter of head gardener of a large park in Geneva, I find semi-buried greenhouses that my grandfather used all year round, even in the snow, for its early sowing, it was (still is) the 'orangery facing due south and protected by a thick wall of north side stones and glossy black wind. I found everything in the book to the scale of a private garden. Congratulations to Claudia Lorenz-Ladener Jaqueline
