HOW TO

Make one yourself.

  1. 1

    Measure your existing first floor

    Start with accurate dimensions of the current layout to ensure the new second story aligns with load-bearing walls and staircases.

  2. 2

    Rough out a base outline

    Using the floor plan creator, draw the footprint of the upper level, marking exterior walls and any overhangs or set-backs.

  3. 3

    Add rooms and openings

    Define bedrooms, bathrooms, closets, and hallways. Place doors, windows, and stairs logically to match the existing structure.

  4. 4

    Refine dimensions and annotations

    Double-check room sizes, closet depths, and ceiling heights. Add labels for fixtures, storage, and measured notes for the contractor.

  5. 5

    Review and export

    Walk through the layout with your builder or designer, make any final adjustments, then download the floor plan as a PDF or image to share.

FAQ

Frequently asked questions

Do I need a professional to create a second story remodel floor plan?01
Not necessarily. Many online floor plan tools let homeowners draft simple layouts. However, for complex structural changes, an architect or structural engineer should review your plan to ensure it meets code.
What should I include in a second story addition plan?02
Include room dimensions, window and door placements, staircase location, and any plumbing or electrical fixtures. Also indicate load-bearing walls from the floor below.
Can I reuse my first floor’s floor plan for the second story?03
Often, yes – especially if the home is a simple rectangle. However, consider roof pitch, dormers, and the need to offset walls for structural integrity or to create interesting layouts.
How do I handle stairs in my second story plan?04
Stairs typically stack above the existing staircase. Be sure to account for headroom and landing dimensions; a 36-inch wide stair with 7-inch risers is common.
