Project Brief

Whether you are a designer or a client, an effective design brief is the single most critical factor is ensuring that a project is successful.

What is a design brief?

A design brief is something that is vital to any design project as it will provide the designer(s) with all the information needed.

“A good brief, like any good document, is the foundation of success. In formulating a good brief, you empower your designer to do what they do best with the potential to deliver a project quite literally beyond your comprehension.” Paul Hindes, Soul Space Building Designer.

The Design Brief is necessary when the client is not clear what the brief should be. This is not as extraordinary as it sounds; often clients are aware that new space needs to be provided or existing space rearranged but the problem may be so complex, and the number of people that need to be consulted so large, that the client is not in a position to analyse this.

This is an area where the designer can provide a service in space planning which clients are often unaware exists. This helps the client to determine his/her needs in detail and to set the parameters for the whole project that may follow.

This can be a relatively simple exercise, e.g. examining how an existing building can be adapted to a new use, or a complex process, consulting exhaustively with the client’s key staff, utilising adjacency theory to provide a detailed analysis of the client’s requirements, developing this into planning diagrams from which floor plans can be developed.

When acting as the interior designer in a design team or when acting as lead consultant, the designer will carry out all of the following tasks:

  • Receive from the client a detailed description of the functions that the project is to accommodate and prepare a room schedule
  • Collect information concerning the precise requirements of each room, interviewing key staff as necessary, and prepare a room requirements schedule for each space
  • When space relationships are complex, prepare an adjacency relationships matrix
  • From the adjacency relationships matrix, develop planning diagrams
  • As appropriate, collaborate with other consultants in the preparation of a design brief
  • Present the design brief (incorporating the above deliverables) to, and review options with, the client.

Initial brief 

A crucial statement (which ideally should be prepared before the designer is appointed to design the Concept stage) is the initial brief. This should set out, in as much detail as the client is able, his/her requirements for the project and should be attached to the appointment letter. If the client has not formulated a detailed brief at the beginning, this should be noted in the appointment letter, perhaps together with a general statement of the client’s intent.

Brief preparation

For large, complex projects, clients often have not carried out a detailed analysis of their requirements. In such situations, the designer can perform a useful service by carrying out such an analysis. This usually involves interviewing key staff, determining what spaces are required, ascertaining the requirements of each space and how it should relate to other spaces, analysing these ‘adjacency’ relationships and preparing diagrams that show the ideal relationships of the spaces to each other. From the latter, floor plan(s) can then be developed in the next stage.

Budget, timetable 

The client should be encouraged to state at the beginning what the desired budget and timetable are and, if they are unable to do so, then this should be noted in the appointment letter. The client should be reminded that under ID/10 clause 3.4, he/she should advise the designer of the relative priorities of the brief, budget and timetable.

Preparing an initial brief 

When projects are small, clients often have a clear idea of what they require. It is important in these cases that the designer either obtains a written statement of the brief from the client or formulates it him/herself from the client’s instructions. If available before the designer is employed, the brief should be attached to the form of appointment.

An initial brief can often be imprecise when the client is unsure of his/her requirements in the early stages of a project.

For many projects (including particularly domestic schemes), it is often convenient to set out the brief on a room-by-room basis. If no work is to be carried out in certain areas this should be noted. Alternatively, say in an office project, the brief can be organised by function and/or the types of personnel a project is required to accommodate.

Tips For The Designer

As a designer it is important to have a template to give to clients as clients will not always come to you with a design brief. By having a template ready, it shows them your professionalism and ultimately saves them (and you) a lot of time and money.
