Architectural Advice & Project Guidance in London | Folly Files
What is "Folly Files"?
Folly Files is our growing library of practical, plain-English articles written to help clients make confident decisions before and during a project. It brings together guidance on design, planning, Building Regulations, procurement and construction — the things that tend to shape cost, programme and risk.
The aim is simple: reduce uncertainty early. Whether you are exploring an extension, refurbishment or loft conversion, or navigating a more regulated project environment, these articles are designed to show what “good” looks like and what to watch out for.

What You’ll Find Here
Our work spans domestic residential projects across Harrow and London — including extensions, loft conversions and full refurbishments — as well as specialist and regulated residential work, including Higher-Risk Building (HRB) projects across London and, where appropriate, throughout the UK.
Folly Files reflects that range. You’ll find articles covering early feasibility, planning strategy, technical design and Building Regulations compliance, contractor selection, contracts and construction-stage delivery — written from a multidisciplinary perspective shaped by architectural practice, project management and developer-led environments.
If you are considering a project and would like to discuss options, constraints and likely next steps, we offer free initial consultations. Use our contact page to get in touch: Contact Folly Architects.

Considering a Project?
If you are exploring an extension, refurbishment or loft conversion — or navigating a more complex compliance-led project such as a Higher-Risk Building — early clarity makes a significant difference.
Many of the topics covered in Folly Files begin with the same questions: What is realistic? What approvals are required? What are the likely risks and costs? A short initial conversation can often help frame the right approach before time and money are committed.
We offer free initial consultations for prospective clients across Harrow, London and, for specialist regulated projects, throughout the UK. Get in touch to discuss your project.
