Hi, I’m Emma.
This is why I wrote the book...
In the past I have spent hours searching for details, trying to find an example of a detail so that I can understand the construction a bit better. When I was at university I was really frustrated with how difficult it was to improve my construction knowledge. There just doesn’t seem to be much clear and concise information readily available on commercial and industrial construction. When you do find what you are looking for it is often difficult to digest. That is why I knew what a valuable resource this book would be for both architecture students and professionals.
After writing several successful construction books (Commercial, Residential US, Passivhaus, Loft Conversions and more), I know that this new edition of the Residential construction book really fills the gap I have experienced both as a student and professional.

Exactly What You Need
AMAZING!
This is exactly what I have been looking for. Having brought Emma’s previous books, I knew this was going to be informative and easy to read but the level of detail Emma has gone to with this book is amazing.
I can’t wait to use this book in my final year at university and throughout my career.

I am glad I stumbled upon your website. I have been looking for a simplified (but still technical) approach to Passivehouse. It looks like you put a lot of work into this book (and the details), I just wanted to let you know work like this is very much appreciated. It will be a big help as I continue on my journey of Passive House design and overall environmentally friendly construction methods here in Canada.

I have just finished reading your book Understanding Passivhaus and wanted to congratulate you on creating something so concise yet useful and comprehensive.It was a really useful introduction to the broad principles of Passivhaus design and the further reading list also looks as though it will prove very helpful.
Matthew - Architect
Thanks for the ebook. It proved very useful for the Passivhaus Designer exam revision which was my original motivation for the purchase. Looking forward to a more leisurely read through now without the pressure and hopefully applying some of it to upcoming projects.
Mark - Architect
Have now received the hard copy of The Passivhaus design book and so far I am impressed, certainly with the clear layout. I will hopefully start incorporating the CAD/SKP details into my new projects.
I have a small Architectural practice working with a partner and I am a Member of CIAT.
I am looking now into maybe getting Passivhaus certified designer, hence the interest in your book.
Dean - MCIAT
Ms. Walshaw’s book is a crucial addition to the literature on passive house design. The details are clear, and the descriptions are concise. Everything you need, nothing you don’t!
