The Royal Institute of British Architects RIBA Stages of Work, is a well-established framework for managing construction projects. It consists of eight stages, beginning with Stage 0: Strategic Definition and ending with Stage 7: In Use [1]. This guide will focus on RIBA Stage 1: Preparation and Brief, highlighting the key elements contributing to a successful project outcome.

Developing the Project Brief
The project brief must contain information that the design team will require to begin the design process in RIBA Stage 2. It may also be necessary to undertake feasibility studies to tease out the full range of briefing considerations and demonstrate that spatial requirements can be accommodated on the site.
Testing the Spatial Requirements against the Project Budget is important, as there is a direct correlation between cost and a building’s area. The design team will need to be selected at this stage.
RIBA Stage 1 Project Strategies
The Royal Institute of British Architects (RIBA) Stage 1, also known as ‘Preparation and Brief’, is a critical phase in the building design and planning process. It’s a stage where the project’s key aspects are identified and defined, providing the foundation for all subsequent stages. It involves conducting initial studies, consultations, and identifying requirements to create a comprehensive project brief. This stage sets the tone for the project, ensuring that everyone is on the same page before proceeding. Here’s an overview of what Stage 1 entails, broken down into various components:
1. Stage 1 – Conservation
- Carry out site surveys and appraisals of conservation areas.
- Research and assess the historical significance of the site.
- Identify and consult with stakeholders interested in the conservation aspects of the project.
- Use feasibility studies to test client’s conservation requirements.
- Draft a statement of significance assessing the project’s impact.
- Identify and hire the required conservation specialists within the design team.
2. Stage 1 – Costing

- Test the project brief against site planning constraints using feasibility studies.
- Determine requirements for Environmental Impact Assessments and other necessary consents.
- Develop a planning brief to inform the project brief.
- Identify and hire necessary planning expertise within the design team.
7. Stage 1 – Plan for Use
- Incorporate lessons learned from previous projects into the project brief.
- The project brief establishes measurable targets for environmental performance, amenities, and comfort.
- Define requirements for post-occupancy evaluation, handover, and maintenance.
- Agree on a schedule for stakeholder engagement.
- Identify and appoint a consultant to act as the Plan for Use champion.
8. Stage 1 – Sustainability
- In the project brief, use feedback and past experiences to define clear, achievable sustainability outcomes.
- Confirm the sustainability outcomes can be met within the budget using feasibility studies.
- Understand and comply with local authority sustainability requirements.
- Define certification requirements, including a timetable for assessor appointments.
- Identify and hire necessary sustainability expertise within the design team.
The Importance of RIBA Stage 1
RIBA Stage 1 is crucial for laying the groundwork for a successful project. At this stage, architects and design teams gather and define the client’s requirements, establish project objectives, and begin considering the project’s constraints and opportunities. This process helps ensure the project’s design and construction align with the client’s vision, budget, and schedule.
Establishing the Project Brief
The project brief is the cornerstone of RIBA Stage 1. It is a comprehensive document outlining the client’s requirements, project objectives, and constraints or opportunities. The brief should include the following components:
- Project objectives: Clearly define the project’s goals and desired outcomes, including functional, aesthetic, and sustainability requirements.
- Site analysis: Assess the site’s characteristics, constraints, and opportunities to inform the design process.
- Budget and financial considerations: Establish a realistic budget and explore funding opportunities or financial constraints.
- Regulatory requirements: Identify any relevant planning permissions, building regulations, and other statutory provisions that may impact the project.
- Procurement strategy: Determine the most appropriate procurement route, considering factors such as cost, quality, and risk management.
- Project programme: Develop a timeline, including each stage’s key milestones and deadlines [3].
Sustainability Considerations
In line with the RIBA Plan of Work 2020, sustainable outcomes should be a key focus during Stage 1 [2]. Architects and design teams should collaborate with clients to establish sustainability targets and ensure they are integrated into the project brief.
Value Management
Value management is a crucial aspect of Stage 1. It involves understanding, challenging, and validating the client’s business needs to ensure the project delivers the best value for money [6]. This process typically includes value management workshops, risk assessments, and options appraisals.
Public Engagement in RIBA Stage 1
Engaging with the public and stakeholders during Stage 1 can significantly contribute to the success of a project. Public engagement allows architects and design teams to gain valuable insights and feedback on proposed developments, helping to shape the project brief and design decisions [7]. This process can also help build project support and mitigate potential objections during planning.
Key Roles and Responsibilities in RIBA Stage 1
During RIBA Stage 1, various professionals contribute to the preparation and brief process. Some of the key roles include:
- Architect: Leads the design team, develops the project brief, and ensures compliance with regulations and sustainable outcomes.
- Quantity surveyor: Provides cost advice and budget estimates and assists in establishing the procurement strategy.
- Structural engineer: Contributes to site analysis, and structural design considerations and helps identify constraints and opportunities.
- Services engineer: Advises on building services design and sustainability targets.
- BREEAM Advisory Professional: Supports the design team in achieving BREEAM performance targets [10].
Adapting RIBA Stage 1 for Different Project Types
While the RIBA Plan of Work is primarily aimed at building projects, its principles can be adapted to suit a range of project types, including infrastructure, landscape, and urban design projects. By tailoring the key elements of RIBA Stage 1 to suit different project types’ specific needs and requirements, architects and design teams can ensure a comprehensive and well-considered preparation and brief process.
Conclusion
RIBA Stage 1: Preparation and Brief is pivotal in any construction project. By clearly defining the project brief, establishing sustainability targets, and engaging in value management, architects and design teams can ensure that a project meets the client’s objectives and adheres to budget and programme requirements. Collaborative efforts by various professionals during this stage are crucial to laying the groundwork for a successful project outcome.

RIBA Stage 1 FAQ
Stage 1, also known as the Preparation and Brief stage, involves the development of the initial project brief and the feasibility studies. This stage is crucial for understanding the client’s requirements, the project’s constraints, and potential opportunities. It also includes the preparation of a project timeline and an initial cost estimate.
RIBA Part 1 is the first step towards becoming a qualified architect. After completing Part 1, typically a three-year undergraduate degree, you can work as an architectural assistant. This allows you to gain practical experience in the field, which is necessary before proceeding to RIBA Part 2.
The duration of RIBA Stage 1 can vary significantly depending on the complexity and size of the project. It can take anywhere from a few weeks to several months. The client and the architect usually agree upon the timeline during the initial project discussions.
No, RIBA Stage 1 is not a professional qualification. It is a stage in the Royal Institute of British Architects’ (RIBA) Plan of Work, which outlines designing and construction a building. The professional architectural qualifications are RIBA Part 1, Part 2, and Part 3.
The term “RIBA Stage 1 architect” is a bit of a misnomer as RIBA Stage 1 refers to a phase in a project, not a level of professional qualification. However, if you’re referring to architects who have completed RIBA Part 1, their salaries can vary widely depending on experience, location, and job roles. As of my knowledge cutoff in September 2021, a Part 1 architectural assistant in the UK could expect to earn between £18,000 and £25,000 per year.
In the context of the RIBA Plan of Work, it would be unusual to skip Stage 1 and proceed directly to Stage 2, as each stage builds upon the work and decisions made in the previous stage. Regarding professional qualifications, you cannot proceed to RIBA Part 2 without first completing Part 1 and gaining some practical experience.
