Plan a home vault closet — room for the full door swing
Everyone who gets a safe asks the same question next: where does it go? The answer is a plan, not a hallway shuffle. An 8×9 interior closet holds a 60-inch standard safe with its door swinging a full 90 degrees, a tall cabinet for documents and backups, a 5-tier shelf for cases and equipment, and a low floor safe in the corner — with standing room left over. The rule the whole layout serves: a safe you can't open fully is a safe you'll stop using.
A vault closet has one job: let you open the safe all the way, every time. A 36-inch safe door swung to 90 degrees stands three feet proud of the cabinet face — and if a bin or a vacuum has crept into that arc, you'll open the door halfway, wrestle things in and out at an angle, and quietly stop using the safe at all. This plan protects the swing first and fills the walls second.
Every piece is in the RoomSketch3D catalog — search the exact names in the Furnish panel, drop them into an 8×9 room, and let the plan prove the door clears before anything heavy gets delivered. It's practical security, not a bunker: four pieces, one clear arc, and a closet guests never see.
What you'll need
- •Standard Safe (36″ × 24″, 60″ tall) — the anchor of the room
- •Garage Tall Cabinet (36″ × 24″, 72″ tall) — documents, backups, the fireproof box
- •5-Tier Shelf 48" (48″ × 24″, 72″ tall) — cases and equipment
- •Floor Safe (18″ × 18″, 12″ tall) — the backup everyone forgets exists
- •An 8 × 9 ft interior closet — and the discipline to keep the middle of it empty
Step by step

The safe on the top wall, door facing the room
Search Standard Safe (36″ × 24″, 60″ tall) and set it back-to-the-top-wall, off-center toward the left, with its door facing down the long axis of the room. That orientation is the whole plan: from the safe's face to the far wall is nearly six feet of open floor, so the 36-inch door swings its full 90 degrees and still leaves close to three feet of standing room behind it. In the real build, this is the piece you bolt down — through the floor into slab, or back into studs.
The vault on the plan — safe and cabinet shoulder to shoulder on the top wall, the door's arc kept clear. - 2
The tall cabinet at its shoulder
Search Garage Tall Cabinet (36″ × 24″, 72″ tall) and place it on the same top wall, about four inches from the safe's right side. This is the paper-and-plastic half of the vault: documents, drive backups, the fireproof box, spare keys. It shares the same open run of floor, so its doors open as freely as the safe's.

The 5-tier shelf down the left wall
Search 5-Tier Shelf 48" and run it along the left wall, front facing into the room, starting about 20 inches below the safe's face. Four feet of shelf, six feet tall, for the bulky and the boxed — cases, equipment, the things too big for a shelf inside the safe. Because it starts below the safe's face, swing the safe door toward the cabinet side and the panel travels over open floor, never the shelf.

The floor safe in the bottom-right
Search Floor Safe (18″ × 18″, only 12″ tall) and tuck it into the bottom-right quarter, a couple of inches off the right wall — outside the big door's arc, across the room from the shelf. It's the piece everyone forgets exists, which is exactly its value: a second, separate location, knee-high and easy to overlook. Use it as the backup for what matters most, or as the decoy that's found first.

Prove the swing in 3D
Switch to 3D — the template draws the walls open so you can see straight into the closet — and stand in the middle of it. The middle is the point: a standing zone a good three feet wide between the shelf and the floor safe, and nearly six feet from the safe's face to the far wall. Picture the door at full swing, both arms in the safe, the cabinet open beside you. If any of that feels tight on the plan, fix it here — the plan is the only place the safe moves easily.

Tips
Bolt it or it isn't secure
On the plan the safe just sits there; in the build it must not. Anchor the safe through its floor holes into concrete, or through its back into wall studs — an unanchored 60-inch safe can be tipped, walked, or dollied out. The top-wall position in this plan exists partly so the safe's back lands on a real wall.
Closets don't breathe — fight the humidity
A sealed safe inside a closed closet is a condensation trap for documents, electronics, and metal. Keep a rechargeable dehumidifier pouch or rod inside the safe and another in the tall cabinet, and renew them on a schedule — a calendar reminder is part of the vault.
Put the vault where guests never see it
The best security feature of this room is that nobody knows it's there. Pick an interior closet off a bedroom or the primary suite, not one visible from the entry or the hallway guests use. A vault that's part of the house tour has already given away half its job.
Common mistakes
Parking anything in the door's arc
The quarter-circle in front of the safe — 36 inches deep, the width of the door — is floor you've already spent. A bin stored there means a door opened halfway, and a half-open safe becomes an unused safe within a month. If the closet gains a new item, it goes on the shelf or in the cabinet, never in the arc.
Letting the cabinet overflow onto the floor
The tall cabinet needs its own 18 inches of clear floor to open, and it shares the room's one open run with the safe. When boxes start stacking in front of it, the vault stops being a system and becomes a storage unit with a very heavy ornament in it.
Forgetting the floor safe — completely
Being forgettable is the floor safe's feature, but it works on you too. Keep a simple inventory of what's in it and check it when you renew the dehumidifier pouches; a backup you can't remember the contents of protects nothing.
Frequently asked questions
How big does a safe closet need to be?
This plan runs in 8 by 9 feet, and the sizing logic travels: the safe's 24-inch depth, plus 36 inches for the full door swing, plus enough floor to stand on while you use it. That's roughly seven feet of run in front of the safe before you add any other storage — which is why a closet, not a corner of a busy room, is the right home for it.
Where in the house should a safe go?
An interior closet away from guest sight lines, on a floor that can carry the weight, with a solid wall or slab behind it for bolting. Ground floors and basements handle heavy safes best; whatever room you pick, place the exact safe on your floor plan first and confirm the door's full swing stays clear.
What is the floor safe for if I already have a standard safe?
It's the second location. Some people use it as the deep backup for irreplaceable items; others use it as the decoy that's found first while the real safe does the work. Either way it's 18 inches square, a foot tall, and easy to miss in a corner — just keep a written note of what's inside, because it will fool you too.
