This is a relatively old but classic book, written by lecturers at The English Gardening School at the Chelsea Physics Garden in London. Years ago I bought it for a self study course on good gardening design basics (and at that time the English were, of course, the best for that kind of training.) And I found it most useful and refer to it again and again.
The editors include the usual range of topics from drawing a good plan, to soil improvers, and on through herbaceous perennials. But, of course, being English, they go on to include the other English garden essentials: 'knots and parterres', espaliers, and of course the orangerie and conservatories. So you get the picture.
Much of the information may be outdated but the pictures are detailed and the techniques are well described and the information is classic. If you can find the book, take a look at it. You will no doubt find out something new and useful.
