In recent weeks, I have acquired a number of books on greenhouses. Some of them merely give you drawings of different types of houses and teach you the principles (position, temperature considerations, water, electicity). Whereas this is all useful it was not really inspiring to me.
The book from RHS gives you a good overview of greenhouse gardening. In addition to that you get inspired. You feel confident and competent after having read this book.
So, if you want something that goes beyond technicalities you need not to search more, you have it here.
Cheerio
Ps. The explanation for the quality of this book you see whenever you visit one of the RHS gardens, where the combination of craftmanship and emotional wellbeing is brought to perfection.
