FIA Monthly: Building Safety Act Toolkit, Liminal Spaces, New Details

Published 14 days ago • 1 min read

Building Safety Act for Principal Designers Toolkit

To help you stay on top of your obligations, we’ve created the Building Safety Act Toolkit for Principal Designers. This resource includes over 30 ready-to-use documents to guide you through every stage of the project — from initial client consultation right through to handing over the design phase.

You’ll find:

  • Project checklists and risk assessment templates
  • Fee proposal letters, terms and conditions, and appointment templates
  • Client care letters, declarations, and end-of-appointment emails
  • Guidance documents to help explain roles and duties to your clients
  • Templates to notify building control and other duty holders

All documents are designed for small-scale domestic projects and can be adapted to your own workflow. A snippet of just one of the many templates can be seen below.

What is Liminal Space?

Learn about liminal space, those long empty corridors, feeling of unease, transitional spaces. A great guide from Valanne.

Over on the Detail Library, Alex Bell explores the role disruption plays in matching problems with solutions in retrofit projects, and helping clients achieve more than they originally thought possible.

That wraps up our news for August. The summer is slowly winding down, and the evenings are getting a little crisper. Take some time to enjoy the sunshine while it lasts and soak up the last of the long days.

Thank you for being here, for reading our emails and for spending some time on our websites.

Your support, comments and feedback mean a lot 🙂

All our best,

Emma and the First In Architecture Team
