Home Design Software
Home Design Software for the House Itself
Arranging furniture is half of designing a home. The other half is the house: the shape of a ceiling, a step down into the living room, the floor running through every room, the color on the walls and the yard outside. RoomSketch3D lets you design those too, and see them together in 3D.

Ceilings with character
Draw a cathedral, single-slope or pyramid ceiling over any part of a room — even one that slopes all the way to the floor for an attic bedroom — and add exposed timber beams, skylights and soffits. The 3D view shows the real headroom, and Smart Flow Check warns when a piece is too tall for the ceiling where it stands.
Vaulted ceilings and attic rooms
Sunken rooms and raised platforms
Lower part of a floor into a conversation pit or raise a reading platform, then add steps in one tap — sized so they add up exactly to the drop. Flooring follows the floor down, and Flow Check warns if furniture straddles the edge.
Sunken and raised floors
Floors and walls you can actually buy
Set flooring room by room — hardwood with your plank width and length, tile, stone or carpet — and see where the cut tiles fall and how many boxes you need. Paint any wall from 10,000+ real Behr, Benjamin Moore and Sherwin-Williams colors, inside and outside faces separately.
Flooring
What it does — and what it doesn't
It does
- Vaulted, sloped and pyramid ceilings with beams, skylights and soffits
- Sunken and raised floor areas with matching steps
- Room-by-room flooring, tile layouts and brand paint colors
- Multi-story homes and the yard around them
- 3D views and optional photoreal AI renders
It doesn't
- Engineer the structure — beams and slopes are for visualizing, not load calculations
- Price materials or labor
- Produce permit drawings

Home Design Software questions
Straight answers, including the limits
Can I design ceilings, not just floor plans?
Yes — cathedral, single-slope and pyramid ceilings, slopes down to the floor for attic rooms, exposed beams, skylights and soffits, all visible in 3D.
Can I plan a sunken living room?
Yes. Lower or raise any part of a floor, add steps sized to the drop, and the flooring and 3D view follow the level change.
Can I see real paint colors and flooring?
Yes — 10,000+ brand paint colors and 40+ real textures, including hardwood with custom plank sizes and tile with a cut-tile layout.
Is this a home remodel tool?
It's great for planning a remodel — trying layouts, ceilings, floors and colors before you commit — and for handing a dimensioned plan to your contractor. It doesn't estimate costs or engineer the structure.
