Who this page is for
- Homeowners renovating kitchens, bathrooms or whole interiors.
- Project owners moving into a new build and planning interiors.
- Anyone preparing to brief a designer for the first time.
What this professional category may help with
- Interior layout and circulation planning.
- Material, finish, fixture, fitting and appliance selection.
- Lighting design — ambient, task, accent layers.
- Storage planning — built-ins, joinery, closets, utility.
- Kitchen and bathroom planning and coordination with trades.
- Color, palette, texture and overall design direction.
- Coordination with architect, contractor and electrical/plumbing trades.
What to prepare before contacting professionals
- Write a household-routine profile (who cooks, sleeps, works, plays where).
- Identify rooms in scope and any layout changes under consideration.
- Confirm any fixed constraints (windows, plumbing stacks, gas lines, panel).
- Collect inspiration that names what you actually like (and dislike).
- Frame a finish-level expectation (basic, mid, premium).
- Confirm appliance, fixture and storage requirements.
- Identify deadlines and dependencies on other trades.
Questions to ask
- How do you structure phases — concept, developed design, specification, procurement?
- How do you coordinate with the contractor, architect and trades on site?
- What is your fee structure — fixed, hourly, percentage, hybrid?
- How do you handle changes to selections mid-project?
- Can you share recent kitchens, bathrooms or interiors in similar contexts?
- What do you typically deliver — drawings, schedules, mood boards, specifications?
Common mistakes
- Designing the look first and forcing function around it.
- Skipping coordination with the contractor on long-lead items.
- Underestimating the impact of layout vs. surface choices.
- Moving plumbing or gas without budgeting for the change.
- Treating the designer's role and the architect's role as interchangeable.
Safety, permits and professional review
- Structural, electrical, plumbing, gas and code-related work should be performed by licensed trades and inspected as required.
- Where layout changes affect structure or envelope, professional review by a qualified architect or engineer is usually appropriate.
- Ventilation strategies — especially for kitchens with gas cooktops — should follow the applicable code and manufacturer requirements.
- Build Design Hub does not provide interior design services.

Frequently asked questions
Common questions about this professional category
What is the difference between an interior designer and a decorator?
Scopes overlap and titles vary by region. Interior designers typically work on layout, fittings and built-in elements alongside surface decisions; decorators more often focus on furnishings, textiles and finishes within an existing layout.
Do I need both an architect and an interior designer?
Sometimes — large or structurally complex projects often benefit from both. Smaller cosmetic projects may need only one. Discuss the scope and have each professional describe where their work begins and ends.
How do interior designer fees typically work?
Fee structures vary widely — fixed fee, hourly, percentage of construction or selections, or a hybrid. Ask each designer how their fees scale with scope and what is included at each phase.
Will Build Design Hub recommend a specific interior designer?
No. The future directory will help shortlist by category and location; verification and final selection remain with the project owner.
