RIBA Stage guide: Process demystified

Introduction

When CROE’s founders, Craig and Joe, began their careers, every architect referred back to the RIBA Stage Guide when preparing a scope of works and justifying a fee. While it remains the industry’s gold standard, the architectural process has become increasingly nuanced. Today, the RIBA Plan of Work is a flexible framework, not a one-size-fits-all checklist.

At CROE, we adapt this framework to each project — whether it’s a simple extension, a barn conversion, or a complex commercial development — to make sure the service matches the brief, budget, and level of support our clients need.

Why One Size Doesn’t Fit All

The RIBA stages provide structure, but the scope of work varies greatly depending on the project and client.

  • A seasoned developer may only need a basic construction pack and minimal on-site supervision.
  • A homeowner refurbishing and extending a listed property often requires a far more detailed service: full drawings, heritage-sensitive specifications, and extensive on-site help. This isn’t just about keeping the planning authority happy — it’s about protecting the building for future generations.

That’s why CROE always begins by listening to the brief, understanding the wider context, and tailoring the level of input to suit.

The RIBA Plan of Work Stages (2020 Edition)

The current RIBA framework (last updated in 2020) sets out eight stages for a project’s lifecycle:

  1. Stage 0 – Strategic Definition
    Understanding the client’s needs and testing whether the project is viable.
  2. Stage 1 – Preparation and Brief
    Developing the initial brief, budget, and programme, and appointing the project team.
  3. Stage 2 – Concept Design
    Exploring design ideas, layouts, and feasibility studies.
  4. Stage 3 – Spatial Coordination
    Developing the preferred design, coordinating with consultants, and preparing planning submissions.
  5. Stage 4 – Technical Design
    Producing detailed technical drawings, specifications, and tender information.
  6. Stage 5 – Manufacturing & Construction
    Administering the building contract and supporting the client during construction.
  7. Stage 6 – Handover
    Ensuring the building is completed, commissioned, and ready for use.
  8. Stage 7 – Use
    Post-occupancy evaluation and ongoing support.

Tailoring the Stages to Clients

At CROE, we treat the RIBA stages as a guide, not a rigid sequence. Every project comes with unique requirements — from budget constraints to client experience, to whether you already have a trusted builder or need us to bring in our network.

  • Some clients engage us only up to planning (Stages 0–3).
  • Others need full technical design and contract administration (Stages 0–6).
  • For heritage and complex builds, we often provide enhanced support, including detailed liaison with local authorities, consultants, and contractors.

We flex our scope so that both the project and its delivery suit your needs.

Why It Matters Now

With construction costs at an all-time high and planning and building control systems under strain, risk management is critical. A well-structured, professionally guided process is the difference between a smooth project and a costly misstep.

As we often say: you wouldn’t trust your pension or life savings to an unqualified advisor — so why treat your project any differently?

Closing

The RIBA Plan of Work remains the backbone of the UK architectural process, but it’s how it’s applied that makes the difference. At CROE, we combine the structure of the stages with flexibility, tailoring our involvement to suit each client’s journey.

Whether you’re a first-time homeowner or an experienced developer, our role is to guide you through the process, reduce risks, and ensure the final building reflects your goals — beautifully, practically, and sustainably.
