So, a disclaimer - I'm reviewing this as an architect, and also reviewing it as a HUGE fan of the first book, "Tom Kundig: Houses". I would give the first volume/book 5 stars.
Here is my biggest issue with this book - I am disappointed that it did NOT provide similar content/presentation/detail as presented in the first book. I would categorize this as a "coffee table" type of book. There are several projects presented (about 20 houses). There is a single presentation (hard-line) floor plan for each project, and an occasional presentation section. It has beautiful photography thoroughly depicting each project, including close-up photos of the Kundig "gizmos". Unfortunately, I'm missing the additional content - there are NONE of the hand-drawn sketches, diagrammatic drawings, process drawings, elevations or site plans, which were included in the first book. I'm bummed. I find Kundig's houses to be very compelling - he has fantastic sites, and his houses have clear organization, and meticulous craftsmanship and detailing. If you like his work, then this volume has a lot to digest, but pictures will be the your primary means to enjoy the work.
I have noticed that Dung Ngo (whom edited the first volume) did not edit this volume. Megan Carey, is editing this volume. Ngo, is credited as the "designer" - not sure what that title means. Not sure if the change in personnel is any explanation for the format change.
I suspect that a non-architect might like this volume better than the first, due to the predominately photographic presentation.
