Design & Build Anything - Blueprints, Cut Lists & 3D Renders in Minutes
RedX Apps covers every phase of a construction project. Design custom decks, roofs, sheds, house plans, and stairs with automatic framing calculations, full material lists, and printable blueprints - available on web, iOS, and Android.
Deck Builder - Design Any Deck with Blueprints & Cut Lists
Any Shape, Any Size
Design a simple rectangle or a complex multi-level deck. The builder handles any footprint with automatic beam, joist, and post placement.
Permit-Ready Blueprints & Cut List
Export a dimensioned blueprint with structural framing layout and a complete cut list - every board, joist, and beam with exact lengths and quantities.
Realistic 3D Renders
See your deck before you build it. Visualize decking styles, railing options, and stair placement in a photorealistic 3D render.
3D Roof Builder - Any Roof Shape, Generated Instantly
Draw Your Perimeter, Get Your Roof
Draw your building footprint and the full roof appears instantly - every rafter, ridge, hip, and valley calculated and placed automatically.
Gable or Hip, Any Pitch Per Side
Set each roof side independently as a gable or hip end with its own pitch angle. Mix and match for any architectural style.
Blueprints, Elevations & Full Material List
Export labeled roof blueprints, elevation drawings, rafter PDFs, plywood layouts, and a complete material and cut list.
Shed Builder - Floor, Walls, Roof & Siding from One Tool
Complete Shed Design from Ground Up
Design your floor joist layout, frame straight and rake walls, add a gable or lean-to roof, and lay out siding - all from one place.
Automatic Stud & Rafter Layouts
Every wall and roof section auto-calculates stud lengths, rafter cuts, and spacing. Rake walls and gable ends are handled automatically.
Printable Blueprints & Cut Lists
Export clean, dimensioned blueprints for every section of your shed with a full cut list - ready for the lumber yard or permit office.
House Builder - Design Floor Plans, Walls & Roof from Scratch
Full Floor Plans with Interior Walls

Auto-Generated Roof from Your Floor Plan
Once your perimeter is set, the roof generates automatically over your floor plan. Customize sides, pitch, and overhangs.
Siding, Renders & Blueprint Export
Visualize exterior siding styles and colors, generate a realistic 3D render, and export complete blueprints with a full material list.
Wall Builder - Frame Any Wall with Blueprints & Cut Lists
Straight Walls, Rake Walls & Tall Walls
Frame any wall type - standard straight walls, angled rake walls for gable ends, or tall walls. Every stud length and bevel angle is calculated automatically.

The Story Behind RedX Apps
I spent years as a full-time carpenter - framing walls, cutting rafters, and doing the math on scraps of plywood. I built RedX because I knew there had to be a better way. Today I'm full-time on these tools, making construction faster and easier for builders everywhere.
