01
From cabin to family home
Start with a simple volume and drag it to size in feet and inches. Add an addition, attached garage or backyard ADU and turn parts 90° at a time.
Houses & cabins
Design your own house or cabin
Sketch a ranch, a two-story colonial, a lake cabin or a rear addition. Build volumes with gable or shed roofs and watch them become floor plans, framing and drawings.

02
Familiar roof shapes
A gable roof like a classic colonial, a shed roof for a modern addition or a low-slope roof for a sunroom. Tall stories can have sloped ceilings upstairs.
03
Floor plans to furnish
Build model creates the floor plans for you. Then draw rooms, doors and windows and furnish as usual.
04
Framing and drawings
With the paid version you get a wood frame with studs at 16" o.c. and trusses, dimensioned plans, elevations and sections, plus a material list.
INSIDE THE TOOL
How it works – from volume to drawing
1. Sketch the volumes
Draw volumes in feet and inches, pull height and width, pick gable, shed or flat roofs and compare sketch versions side by side.
2. Build model and framing
The model works out walls, floor joists, trusses and prefab panels with estimated weight and shipping size. Set your own span and transport limits.
3. Drawings and material list
Dimensioned plans, elevations and sections to scale with title block, north arrow and grade line. Export PDF, CSV, IFC and 3D.
BUILDING PERMITS
A solid starting point for your permit
MyRoomCraft gives you drawings in the format building departments usually ask for – but the application remains your responsibility.
What you can produce in the tool
- Scaled floor plans with dimensions and square footage
- Elevations for all four sides with grade line
- Section with story heights
- Title block, north arrow and page numbers
- Material list and framing basis for contractor bids
What you usually arrange separately
- Survey or plot plan of your property
- Structural calculations stamped by a licensed engineer where required
- Energy code compliance (e.g. Manual J / REScheck)
- Zoning review and HOA approval
- Separate electrical, plumbing and mechanical permits
Requirements vary by state, county and city. Always check with your local building department before submitting.
THE LOT AND THE PLAN
What can you build on your lot?
A new house always needs a building permit. Your zoning district sets size, height and position on the lot.
Zoning
Your zoning district sets minimum lot size, setbacks, lot coverage, height and allowed uses. Plan review checks your drawings against it.
Building code
Most states adopt the International Residential Code (IRC) with local amendments for structure, egress, fire safety and stairs.
Energy and utilities
Energy code (IECC) compliance, plus water, sewer or septic and power connections, are reviewed separately.
HOA and inspections
Subdivisions often have HOA design rules. Construction is inspected in stages: foundation, framing, MEP and final.
THREE HOUSE TYPES TO START FROM
From cabin to family home
Examples to start from – redraw in feet and inches and furnish with real dimensions.
Ranch
1,000–1,500 sq ft on one level: three bedrooms, two baths and an open kitchen-living space.
Two-story colonial
Living, kitchen and powder room downstairs, bedrooms upstairs.
L-shaped family home
Primary suite in its own wing with a covered patio.
FROM LOT TO BUILDING
How it works
- 1
Lot and position
Enter lot size and slope and place the house inside the setbacks.
- 2
Volumes and roof
Sketch volumes, choose roof shape, siding and roofing.
- 3
Floor plans and interiors
Build model creates the floor plans – draw rooms and furnish.
- 4
Drawings and permit
Export drawings to scale as a basis for your permit application.
THE DRAWING SET
For your permit application
Drawings from your model – the same measurements on every sheet.
Site plan
The house on the lot with setbacks to property lines and the street.
Floor plans
Every story with room names, doors and windows.
Elevations
Every side with grade line and materials.
Sections
Floor levels, ceiling heights, ridge and pitch.
Drawings are a basis, not a permit. Check zoning with your local building department and have structure verified by a licensed engineer.
