What is a design brief?

A design brief is a document you prepare for your designer that captures your project goals, aesthetic preferences, functional requirements, budget, timeline, and any constraints. It gives the designer a foundation to work from so that the first concept presentation is aligned with your actual vision rather than a generic interpretation of it.

How specific should a design brief be?

As specific as possible on function and budget; directional rather than prescriptive on aesthetics. Specify exactly how you use a room, your storage needs, pieces you want to keep, and your hard budget ceiling. For aesthetics, provide images rather than words — 'modern' and 'cozy' mean different things to different people, but a curated set of 20 images is unambiguous.

Should I share my budget in the design brief?

Yes. Withholding your budget does not protect you from being overcharged — it results in proposals and concepts misaligned with your actual constraints. A professional designer will not raise their prices because they know your budget; they'll use it to calibrate recommendations. Specify both your target budget and your hard ceiling.

How to Brief an Interior Designer: What to Include and Why It Matters

May 22, 2026

Why the Brief Matters More Than the First Meeting

The initial consultation with a designer is conversational and exploratory. The design brief is the document that actually shapes the first design concept. Without a brief, the designer is working from memory of a conversation and their own interpretation of your aesthetic. With a clear brief, they're working from a precise document they can return to throughout the project. The brief reduces revision rounds, protects your budget, and makes the working relationship significantly more efficient.

Section 1: Project Overview

Start with the basics: which rooms are in scope, why you're doing this project now (renovation trigger, lifestyle change, new home), and your overall goals. Be direct about what success looks like. "I want this space to feel like a calm retreat after work" is more useful than "I want it to look nice."

Section 2: How You Use the Space

This is the most underutilized section of most briefs — and the most valuable for your designer. Describe in practical terms:

How many people use this room and how often?
What activities happen in it? (Working from home, entertaining, children's homework, morning coffee?)
What are the peak-use times and how does the light change throughout the day?
What storage do you need that you don't currently have?
What doesn't work about the current room that must be solved?

Section 3: Aesthetic Direction — Images Over Words

Collect 20–30 images of rooms you genuinely like — from Houzz, Pinterest, magazine archives, or screenshots of homes you've visited. Organize them in a shared folder (Google Drive or Dropbox works well). Then add a brief note for each image, or for the collection as a whole: what specifically appeals to you. Is it the light? The color palette? The furniture scale? The material choices? Specificity here prevents the designer from guessing.

Also include five to ten images of rooms you don't like and wouldn't want to live in. Negative examples are often as valuable as positive ones.

Section 4: Pieces You Want to Keep

List every piece you want to keep — furniture, art, rugs, lighting. Include dimensions if you have them. Note any pieces with sentimental value that cannot be removed even if they don't fit the new design direction. This is critical information: a designer who doesn't know about your grandmother's armchair may design a layout that has no place for it.

Section 5: Non-Negotiables and Constraints

Be explicit about hard constraints: a wall that cannot be moved, a flooring material you've already committed to, a renovation budget ceiling that is truly fixed. Also note practical constraints: pets that will use the space (fabric durability matters), children who will eat in the living room, a partner with different aesthetic preferences who has veto power.

Section 6: Budget

State your total budget for the project including furnishings, and separately note your ceiling for design fees. If you've read our interior designer cost guide, you'll have a realistic sense of what design fees to expect. Being clear about your total budget — "I have $35,000 total for this room including design fees, furniture, and any minor construction" — gives the designer what they need to calibrate every recommendation appropriately.

Section 7: Timeline

If you have a deadline (hosting an event, moving in by a date, selling the home), state it. Designers plan procurement lead times backward from installation. Knowing your hard deadline upfront determines which vendors and options are available to you. Rushed timelines limit choices and often increase costs — honesty about this is in your interest. Browse designers in your area who are accepting new projects and can meet your timeline.
