Designing around the angle
Denis FilippiniCustom bookshelves for sloped ceilings, staircases & awkward spaces
Ever stared at that angled wall or the space under your stairs thinking,
“What can I actually do with this?”
You’re not alone. These architectural “gaps” are some of the trickiest parts of the home to furnish — and most people either ignore them or pay for expensive built-ins.
But here's the good news:
You don't need built-ins. You need a better shelf.
At The Perfect Bookshelf, we create modular, made-to-fit shelving that adapts to your architecture — even the quirky parts. Whether it’s a sloped attic wall, a cathedral ceiling, or that dead zone under your stairs, we’ll help you turn it into something beautifully functional.
Sloped Ceiling? Vaulted Wall? No Problem.
Homes with character come with quirks: A-frames, vaulted ceilings, sloped attic walls. Most standard furniture just doesn’t fit.
Big-box bookshelves are too tall. Flat-pack solutions waste space. And custom carpentry? $$$.
That’s where we come in.
Our modular system lets us design shelves that trace the exact angle of your ceiling or wall.
Instead of fighting your space, we build with it — and the result is striking.
“We finally made that awkward living room wall feel intentional. Now it's everyone's favorite corner.”
— Sarah & John
Under-Stair Shelving that Makes a Statement
Under-stair spaces are often wasted or crammed with baskets. But with a custom shelf built to mirror the angle of your stairs, you can turn it into the centerpiece of your home.
This isn't just storage — it’s sculpture. A grid of books, objects, art, and plants that adapts perfectly to your wall’s shape. And because our system is portable, you can take it with you if you move.
“Now it’s the first thing people notice when they walk in.”

How to Measure for a Sloped Wall or Staircase Shelf
You don’t need tools or blueprints. Just take three quick measurements and send us a photo.
1. Measure Total Length (L)
Use the floor as your guide.
Measure from one side of the wall to the other (baseboard to baseboard).
If there’s trim or millwork, measure inside edge to inside edge.
2. Measure Both Heights (H & H1)
H = floor to ceiling at the lowest end of the slope
H1 = floor to ceiling at the highest end
Tip: Always measure below ceiling beams or trim.
3. Snap a Photo
A clear shot of the full wall or stairs helps us understand the angle and lighting.
