How to Choose an Interior Designer: 10 Questions That Separate Good from Great
Bold ideas. Thoughtful execution.
Short answer: Choose an interior designer whose process covers concept to delivery, whose portfolio shows the kind of space you actually have, and who tells you what they won't do. Ask these 10 questions — about process, scope, suppliers, communication, and how they handle problems — and the right studio will sound specific where others sound vague.
Hiring the right designer matters more than hiring a famous one. Fit is everything: a brilliant hospitality designer can still be wrong for your family home. This checklist gives you the questions, the answers that should reassure you, and the warning signs that should stop you — plus, transparently, how we at Hello my space 39 answer each one, so you can judge us by our own standard.
Before you ask anything: check these five things
You can shortlist studios in fifteen minutes before a single call:
Portfolio reality-match. Look for finished projects that resemble yours — same room type, similar scale. A studio's portfolio should show real completed spaces, not only mood boards.
A stated process. A serious studio publishes how it works. Ours has four stages: concept, spatial planning and design development, technical details and coordination, and execution with turnkey delivery.
Services that match your need. Full-service design, design support, sourcing only — check they offer the scope you want.
Named people. You should know who you're hiring. Our studio is built around founder Gabriela and partner Iulia — not an anonymous brand.
Proof from past clients. Testimonials that describe process and outcome, not just "amazing!".
The 10 questions you need to ask
1. What is your design process, step by step?
Why it matters: the process is where quality is actually made. Vague process = vague project.
A good answer sounds like: specific stages with names, what happens in each, and what you receive. Ours: concept and big idea first, then spatial planning and design development, then technical drawings and coordination with suppliers and contractors, then execution delivered turnkey.
Warning sign: "We just start designing and see where it goes."
2. Do you design from a concept, or decorate around my purchases?
Why it matters: concept-driven and decoration-driven produce different homes — layered and coherent versus assembled.
A good answer sounds like: a concept phase that comes from your life. As our founder Gabriela says, "every project is treated as a unique story rather than a standard solution."
Warning sign: a catalogue of "your style options" before they've asked how you live.
3. What exactly is included in your fee — and what isn't?
Why it matters: scope mismatches are the #1 source of project friction.
A good answer sounds like: a clear scope menu (full journey, design support, product sourcing alone — all possible with us) and written agreement before work starts.
Warning sign: anything that avoids the question, or "we'll figure that out later".
4. How do you balance aesthetics with how I actually live?
Why it matters: a beautiful space that fights your routines fails within a year.
A good answer sounds like: questions about your routines before opinions about your sofa. Our partner Iulia: "Good design should feel inevitable: layered, personal, functional."
Warning sign: leading with trends instead of with you.
5. Who will actually work on my project?
Why it matters: the person who sold you the project isn't always the one delivering it.
A good answer sounds like: names, roles, and continuity — who you talk to, who manages contractors. With us, Gabriela and Iulia are personally involved from first conversation to delivery.
Warning sign: "a team member will be assigned."
6. How do you handle technical work and contractors?
Why it matters: this is where renovations succeed or collapse.
A good answer sounds like: technical drawings and specifications finalized before building, and active coordination with suppliers, manufacturers, and contractors — accuracy and feasibility checked on paper, not on-site at your expense.
Warning sign: "the contractor will handle the technical side."
7. Where do you source products and materials?
Why it matters: sourcing determines quality, lead times, and what your budget buys.
A good answer sounds like: named, established partners. We work with a network including KVIK kitchens, String Furniture, Woon Dutch Furniture, Peintagone paints, EKOKOZIJNEN windows, Photowall and VLALA wall décor, and fovere acoustic solutions.
Warning sign: no supply relationships, or markups they won't explain.
8. Can I speak with past clients or see finished projects?
Why it matters: anyone can promise; portfolio and references verify.
A good answer sounds like: "Yes." A live portfolio plus client testimonials with names and cities — our clients from Berlin, Amsterdam, Rotterdam, and Utrecht describe both process and result.
Warning sign: renderings only, or clients who "prefer to stay anonymous" — every single one of them.
9. How do you handle changes and problems mid-project?
Why it matters: every real project has surprises; character shows in how they're managed.
A good answer sounds like: a change process, honest communication, examples of problems solved. Our clients mention "clarity, patience, and professionalism" through a complex renovation — that's the tone to listen for.
Warning sign: "problems basically never happen."
10. What do you need from me for this to succeed?
Why it matters: great design is a collaboration; the best studios set expectations upfront.
A good answer sounds like: specific asks — honest pain points, the people who use the space in the conversation, your non-negotiables. That's exactly what we ask for in a first consultation.
Warning sign: "nothing, just approve the design."
How to run the comparison
Shortlist three studios using the five pre-contact checks.
Send the same brief to all three — same rooms, same photos, same wishes — so answers are comparable.
Ask all 10 questions, note the answers in the good-answer/warning-sign frame above.
Judge specificity. The studio that talks about your routines, your light, your suppliers — in concrete terms — is the one that will deliver.
Check the fit, then the fee. Price only means something after scope is clear; compare scopes, not just numbers.
FAQ
How do I know if an interior designer is good? Three checks: a portfolio of real finished projects (not just renders), a published process, and testimonials that describe the journey. Then one conversation — a good designer asks about your life before proposing a style.
Should I choose a big firm or a boutique studio? Firms offer scale; boutiques offer the principals' personal involvement. If you value working directly with the founders — and hearing honest advice like "this project doesn't need us yet" — choose boutique.
What should I prepare before contacting a designer? Photos of the space, what's not working, images you like (inconsistent is fine), and your non-negotiables. That's enough for a productive first consultation.
How do I compare quotes from different designers? Compare scope, not price: what stages are included, who coordinates contractors, whether delivery is turnkey. A cheaper quote that excludes coordination can cost more by the end.
