In a residential new build, the floor framing plan is where the architecture meets the structure. Get it considered early and the project flows; leave it late and you risk rework when the layout and the structure don't agree. This guide walks through how framing plans fit into a new build and how to use a preliminary one to your advantage.

If framing plans are new to you, start with what a floor framing plan is or the complete floor framing plan guide.

Where the framing plan fits in a new build

A typical sequence:

  1. Architectural layout fixes the rooms, walls, and openings.
  2. Preliminary framing plan works out how each floor is supported — joist direction and spacing, beams, bearing walls, openings, and any grid and columns.
  3. Engineering review confirms spans, sizes the members, and ensures the structure suits the loads and local code.
  4. Construction documents carry the reviewed, detailed plan the crew builds from.

Steps 1 and 2 are tightly coupled — they should inform each other rather than happen in isolation.

Coordinating structure with the layout

The most common new-build headaches come from structure and architecture drifting apart:

  • A stair or duct opening on the architectural plan must be framed, with headers carrying the interrupted joists.
  • Bearing walls the structure depends on can't be casually moved for a nicer room layout without rethinking support.
  • Spans that are too long for an efficient floor push you toward deeper members or an intermediate beam.

Sketching a preliminary framing plan over the layout surfaces these early, while they're still cheap to fix.

A sensible starting approach

For each floor:

  1. Set the footprint from the architectural outline.
  2. Run joists across the shorter span so each joist reaches less distance. (See floor joist spacing explained.)
  3. Confirm the bearing walls the joists land on. (See load-bearing walls.)
  4. Add openings and headers for stairs and services.
  5. Add a grid and columns if the plan is large enough to need them.
  6. Export a PDF for review and a DXF for the engineer.

A framing plan template can give you a running start on a typical house.

Multi-storey considerations

A house with more than one level stacks floors, and the framing on each level has to make sense with the ones above and below — load paths need somewhere to land. For that, see floor framing plans for a two-storey home.

Keep it preliminary

A new build is exactly the kind of project where engineering review is essential. Use the preliminary framing plan to coordinate and communicate — then have a qualified engineer review, size, and detail the structure for your loads and local code.

Try it

Lay out each floor of your new build and export clean preliminary drawings. Open the framing studio to start, or adapt a template.
