Top 3 Space Planning Mistakes Designers Make
Space planning is where creativity meets functionality—and where many new designers unknowingly sabotage their own projects. Avoid these 3 common pitfalls to create polished, professional layouts every time.
- Mistake 1: Designing for Looks, Not for Living
- The Problem:
New designers often get caught up in aesthetics—Pinterest boards, trending styles, and color palettes. But great space planning starts with how the space will function, not how it will look in photos.
- Real Talk:
It doesn’t matter how beautiful a room looks if people can’t move through it comfortably or use it intuitively.
- How to Avoid It:
- Start with behavior mapping. Ask: How will people move, gather, and work in this space daily?
- Prioritize flow over features. Furniture and pathways should support natural movement—not obstruct it.
- Use scaled furniture cutouts or software to simulate real usage before committing to a layout.
- Mistake 2: Ignoring Architectural Constraints
- The Problem:
Many beginner designers treat the space like a blank canvas—ignoring things like door swings, outlet placements, HVAC vents, or structural walls.
- The Result?
Layouts that look good on paper but fail miserably in the field.
- How to Avoid It:
- Always measure twice, design once. Use a laser measure and draw an accurate floor plan, including immovable features.
- Mark door swings and window lines so you don’t block key access points.
- Collaborate with contractors or architects early in the planning phase if you’re not sure what can and can’t be moved.
- Mistake 3: Forgetting Human Scale
- The Problem:
Rookie layouts often cram too much into a space or use oversized furniture that looks good online but doesn’t fit in real life.
- The Fix:
Design with human scale in mind. That means creating spaces that feel balanced, usable, and proportionate to the people who will live or work there.
- Pro Tips:
- Leave minimum 36” between furniture for comfortable walking space.
- Don’t default to oversized sectionals in small living rooms—go modular instead.
- Test your layout in 3D, either digitally or by taping furniture outlines on the floor.
- Bonus Tip: Use a Space Planning Checklist
Want to double-check your layouts before presenting to clients or contractors? Use a professional checklist that walks you through flow, clearance, ergonomics, and function. (Psst… we include one inside the Interior Design & Construction Masterclass!)
- Final Thoughts
Space planning isn’t just about fitting things in—it’s about designing experiences. When done right, it becomes the invisible force that makes a space feel right, even if people don’t know why.
By avoiding these three common mistakes, you’ll not only improve your designs—you’ll earn serious credibility on job sites and with clients.
