Without documented processes,
your practice is a person.

  • 🧠
    Knowledge lives in people, not systems
    When your most experienced team member leaves, your processes leave with them. Undocumented practices cannot be trained, audited or scaled.
  • 📋
    Inconsistent quality across projects
    Without a standard process, every project runs differently. Client experience and delivery standards vary depending on who's managing it that week.
  • ⚖️
    Regulatory exposure
    CDM, Building Regulations, planning obligations. Without documented procedures, compliance depends on individual memory rather than practice policy.
  • 🏆
    Clients notice the difference
    A practice with documented processes communicates professionalism before a single drawing is issued. SOPs underpin the client experience from first contact to handover.
"Professional practices don't just deliver great design. They deliver a consistent, repeatable experience. That requires documented process, not just talented people."
Pearl Ume, Architect & Founder, DesignFlowOS

Eight series.
Every stage covered.

Every SOP referenced against current UK legislation and professional body standards, structured from first enquiry through to post-occupancy. Switch discipline to see each set; your purchase includes both.

Still have a question? DM @designflowos

Do I get both the architecture and interior design SOPs? +
Yes. One purchase includes both complete libraries: all 35 architecture SOPs and all 57 interior design SOPs, 92 in total, across Series A–H in each discipline.
What format are the SOPs delivered in? +
Two formats: full A4 Word (.docx) documents with professional formatting, and concise Notion-ready markdown versions. Both arrive in the same download.
Can I edit and customise the documents? +
Yes, fully. Every Word document is editable. Add your practice name, adjust procedures to match how you work, change the language, add sections. A professional starting point, not a rigid template.
What's the geographic scope? +
The architecture library is UK-specific: RIBA, ARB, CDM 2015, UK Building Regulations and JCT forms. The interior design library is global: its compliance SOPs reference standards across jurisdictions (BS 8300 / ADA / AS 1428 / EN 17210 for accessibility, Euroclass / BS 476 / ASTM / AS for fire, UKCA / CE / UL / RCM for products), so it works for interior designers internationally. Business and project-management SOPs in both apply broadly.
I only work in one discipline, is it still worth it? +
Yes. At £27 for both libraries, even one discipline's set alone is exceptional value, and the second library is included at no extra cost, useful if your work ever crosses over or you collaborate with the other discipline.
How does delivery work? +
Immediately after purchase you'll receive an email with your download link. All Word documents and Notion files for both libraries are in a single organised download, ready to use immediately.
How does this relate to the rest of DesignFlowOS? +
Studio OS includes shorter Notion mini-SOPs as in-workspace reference guides. This library is the full, expanded set, designed to complement and complete your DesignFlowOS setup, or stand alone.
Are future updates included? +
Yes. One purchase gives you lifetime access and all future updates, including additional SOPs and updates reflecting changes in UK legislation or professional standards.
