Where to go next.

Concept.

What it means in interior design.

A concept is the central idea a design is built on: a layout strategy, a mood and a material direction that answer the brief together.

In practice

Present one strong concept with its reasoning rather than several weak ones. Mood boards and loose plans are enough at this stage; detail comes later.

Brief

A brief is the client’s statement of what the project must achieve: who it is for, what it must include, the budget, the timescale and any fixed constraints.

Program

A program, or space schedule, turns the brief into spatial requirements: each activity, its users, its target area and the spaces it must sit near.

Design development

Design development is the stage that turns an approved concept into a resolved design: fixed layouts, chosen finishes, sized joinery and coordinated services.

Tender

A tender is the process of asking contractors to price the same set of documents, so their prices can be compared like for like.

Specification

A specification is the written description of what is to be supplied and how it is to be installed: products, materials, finishes, standards and workmanship.

Snagging

Snagging is the inspection near the end of a project that lists defects and unfinished work, called snags, for the contractor to put right before handover.
