We have put together all the details (UK construction) from our books, and more, and made them easily available on one platform. The library is categorised and searchable, to make it easy to find the exact detail you are after, time and time again.

Over 200 Details

Our details are focused on the residential market, and based on UK construction methods and standards. The library is constantly growing, and if there is a detail missing that you specifically need – just let us know and we can draw it for you!

New Details Added This Month:

LC23 – Loft conversion Velux eaves window

LC22 – Loft conversion Velux balcony

LC07 – Loft conversion party wall upgrade

How does it work?

The Detail Library works on a subscription model – where you sign up for a membership and get access to the details, 24/7. There is no download limit, and no restrictions on use. There are two membership options that provide different file versions.

If you only need a couple of details, you can purchase individual detail files. 


Subscription model not for you? Don’t worry, if you are just looking for one or two particular details, you can purchase individual detail files as you need them

Who is it For?

The detail library is for any architect, architectural technologist, student, self builder or anyone wanting access to a large selection of UK construction details.

Lite Membership consists of the details in dwg format. If you sign up to Lite Membership you must be able to open dwg files in version 2010 or above.

Many of the details are featured in the Understanding Architectural Details books. If you own the full set of books, you may not need to sign up for the detail library. Please contact me to discuss and go through your specific situation.

Please note we do not currently accept memberships from educational institutions – please contact us to discuss membership options for your institution.

Want A Discount?

Submit your own details to get a discount! You can submit your details, which will be checked by our team, and if approved you will be eligible for a discount to the platform. Discounts start at 1% per detail, but increase if the detail has been built and there is a photograph of that detail!

So, for just a few submitted details you can quite quickly get a heavy discount to access the rest of the library. If you want to know more, don’t hesitate to drop us an email:
