Modern Construction Envelopes second edition was originally based on the two books by Andrew Watts, Modern Construction Roofs and Modern Construction Facades . Both volumes were gathered into one single volume and consolidated in terms of content, which permits the consideration of facades and roofs as envelopes. Using current examples by renowned architects, Watts presents the constructive and material-related details. This presentation is based on a text, photos, and standardized detail drawings, as well as 3D representations of the components. The new edition has 3D views that are easier to understand than the first edition, with sharper images and more key explanations.
