15 Subtle Signs You Didn’t Hire an Interior Designer
Spot the telltale clues that set a professionally designed home apart from DIY decorating—and discover how to fix the most common home design mistakes.
Even the most stylish among us can miss the mark when it comes to pulling together a cohesive, beautiful living space. Skilled interior designers possess not only a trained eye for detail, but also a practical understanding of what turns a house into a harmonious, inviting home. If you’ve ever walked into a room and felt something was amiss—or too predictable—chances are, your space is showing clear giveaways of a DIY approach. Here, we uncover the 15 most common signs you didn’t hire an interior designer, and offer expert guidance on how to fix them for a space that looks and feels bespoke.
1. Everything Matches Too Much
Walking into a room where every piece of furniture matches perfectly—same color, same style, even the same manufacturer—may feel safe but can make your space appear flat and uninspired. Designers skillfully curate pieces to create an intentionally layered, lived-in aesthetic.
- Redundant matching sets (sofas, chairs, tables) lack depth.
- Uniform colors or finishes create a showroom feel rather than a homey ambiance.
- Solution: Mix vintage and contemporary elements, blend different finishes, and add unique accessories for character.
2. Generic Artwork and Decor
Stock prints, impersonal wall art, or mass-produced decorations signal a missing personal touch. Interior designers help you find items that reflect your individual story and taste, seamlessly integrating them with the room’s overall concept.
- Common signs include abstract canvases seen in chain stores and uninspired word art.
- Solution: Display personal photos, original art, sculptural pieces, or meaningful objects acquired while traveling.
3. Lack of a Focal Point
Open a magazine and you’ll notice every professionally designed room has a clear focal point, whether it’s a stunning fireplace, a statement piece of furniture, or bold artwork. DIY homes often spread visual interest too thin, leaving nowhere for the eye to rest.
- TVs, clutter, and scattered seating obscure attention.
- Solution: Designate a prime element in each space and arrange furniture and decor to draw attention to it.
4. Improper Furniture Placement
Furniture awkwardly hugging the walls, or conversely, clustered in the middle with no logic, often results from guesswork rather than planning. Interior designers map out clear traffic flow and ensure scale matches the size of each room.
- Poor layouts can cause congestion or leave spaces feeling barren.
- Solution: Arrange seating to facilitate conversation and functional movement paths. Use area rugs to define zones.
5. Every Wall Is Crammed
Filling every inch of wall with artwork, shelves, or knick-knacks leads to visual overload and can shrink a space. Designers understand the power of negative space in making rooms feel balanced and breathable.
- Over-accessorizing makes it hard for standout pieces to shine.
- Solution: Edit relentlessly—only display art or objects you truly love, leaving plenty of open wall for calm.
6. Overreliance on Trends
Jumping on every new design fad—think velvet everything, ultra-modern lighting, or overly themed motifs—can quickly date your home. Designers selectively incorporate trends within a timeless foundation.
- Rooms dominated by one era or Instagram trend appear easily outdated.
- Solution: Ask if you’d love a look even when it’s out of style. Balance trendy elements with classic furnishings.
7. Poor Lighting Choices
Lighting can make or break a space. In homes without designer guidance, harsh overheads, mismatched lamp styles, or insufficient layers produce uncomfortable or gloomy atmospheres.
- Common issues: Only using ceiling fixtures, inconsistent light temperature, ignoring natural light opportunities.
- Solution: Layer lighting with ambient, task, and accent options. Choose dimmers and bulbs that mimic daylight for a warm, flexible mood.
8. Neglected or Awkward Spaces
Unused nooks, undefined hallways, or blank unused corners quickly reveal DIY design. Interior designers maximize function and style in every inch—turning the oddest crannies into reading spots or stylish display areas.
- Wasted space is uninviting and underutilized.
- Solution: Add a console table, built-in bookshelves, or a cozy chair to bring forgotten spots into the home’s flow.
9. Visible Clutter and Poor Storage
Messy surfaces and overflowing shelves suggest a lack of planning. Designers create storage solutions that blend beauty and practicality, keeping daily clutter artfully out of sight.
- Clutter detracts from even beautiful furnishings.
- Solution: Integrate closed cabinets, baskets, or custom solutions to house essentials discreetly.
10. All-Neutral Everything
While a neutral palette can look soothing, too much beige, gray, or white can turn a home monotonous. Professionals inject color—through pillows, accents, or art—to create warmth and vibrancy.
- One-tone rooms lack visual interest and become tiresome.
- Solution: Add pops of color or texture—through textiles, plants, or painted furniture—to enliven and personalize your home.
11. Ignoring Scale and Proportion
Bigger is not always better. Small furniture in a large room (or oversized pieces crammed into small spaces) disrupts balance and flow. Professionals measure and select items precisely suited to their surroundings.
- Misfit pieces feel awkward and disrupt movement.
- Solution: Choose furnishings that match your room’s dimensions and ceiling height, paying attention to both relaxation and function.
12. Forgetting Ceilings and Vertical Space
Amateur decorators often focus only on what’s at eye level. Designers view rooms in 360 degrees, using ceiling treatments, pendant lighting, or tall bookcases to draw the eye upward and maximize every plane.
- Blank ceilings make rooms feel unfinished.
- Solution: Paint, add beams, wallpaper, or artful crown molding; hang curtains and lighting fixtures higher to expand the sense of space.
13. Single-Purpose Rooms
Multipurpose design is the norm for modern living, but many DIY spaces overlook flexibility. Designers create adaptable rooms, layering form and function so that spaces transition effortlessly from work to play and back again.
- Lack of versatile furniture limits usability.
- Solution: Incorporate modular pieces, clever partitions, and storage ottomans to shift rooms for different activities.
14. Neglecting Exterior Style
Great designers carry the look and feel of interiors to the exterior—ensuring color, materials, and style are in harmony from the front porch to the living room. Many homes without designer input have a disconnect between inside and out.
- Sharp style breaks or ignored landscaping disrupt curb appeal.
- Solution: Repeat motifs and color palettes outdoors, coordinate planters or front door color, and extend living space to patios and gardens.
15. Dated or Builder-Grade Finishes
Standard trim, basic banisters, or cheap fixtures are often left untouched in DIY rooms, betraying a lack of professional polish. Interior designers add custom, finishing touches for a curated, bespoke look.
- Features like heavily varnished railings or plain cabinet hardware age your space.
- Solution: Upgrade with painted or matte finishes, swap knobs and pulls, and consider unique moldings or wall treatments.
