Buying the Guide

Buying the Small Scale Green Roof Guide

To buy the guide use the Register button in the menu at the top of the page. We now offer a second option for membership, an annual subscription. You can select which option you prefer on the Registration page. Both membership types offer identical levels of access but the subscription membership needs to be renewed annually.

As this is both a public and private site once you log into the RESTRICTED MEMBER SECTION then links to all the pages and chapters will appear on the right hand side.

There is a linear logic to building a green roof. However there are crossovers between sections/chapters and videos/sketches that may be relevant in a particular chapter but reside somewhere else. Therefore we have provided internal hyperlinks between various sections, chapters and multimedia pieces.

This should make the guide easily navigable and user friendly.

We can also provide the original PDF for people who want to print something off to use onsite. An important new chapter that is not in the 1st edition PDF is the Gabion Edge detail. If this is needed in hard copy then it will have to be printed from the website.

If you have suggestions to make the site more user friendly we would welcome these. Any innovations you come up with and are willing to share with us – please do let us know.
