Where To Find Construction Details On The Web
[UDATED May 2021]
Good resources and precedents for construction details can be hard to find. You can spend hours trawling through google looking for detail inspiration but never quite find what you are looking for.
I have put together some of the most useful resources I have come across so far, but, I’m sure there are many more out there I’ve missed so please comment below, or drop me an email to make sure your ‘go to’ detail website gets added to the list.

The Detail Library

Our very own construction detail library is now packed full of over 200 construction details! We have everything ranging from foundation details, wall and window details, pitched roof details, flat roof details, plus a huge range of passivhaus details. We add to the library every month and are currently working on additional resources to make our members lives a bit easier. Go check out the library!

Associations and Regulations and Guidance

Accredited Construction Details ACDs for Part L

Although these details where archived in 2015 and are no longer updated, they still provide a useful base for your studies. The details were created to help the construction industry achieve the performance standards required to demonstrate compliance with the energy efficiency requirements of Part L of the Building Regulations. They include details for Steel Frame, Timber Frame, Masonry Cavity and Masonry Internal/External. All downloadable PDFs, very useful to keep in your own reference library.

Journals and Magazines
