Construction Cost for a 1,200 Sq Ft House

Last updated 2026-10-28

These are indicative planning estimates, not a contractor quotation. Actual costs depend on site conditions, design, location, material specifications, labour rates and local approvals.

At 1,200 sq ft, most families get three bedrooms or two bedrooms with a study, a separate dining area and a comfortable kitchen.

Single floor or two floors?

A single floor of 1,200 sq ft needs a large footprint. Many plots cannot host that after setbacks, so builders often use two floors of about 600 sq ft each, or a ground floor plus a smaller first floor. The tables below show both; the two-floor version applies a small illustrative rate factor because some foundation and site costs are shared across floors.

Decisions that move the budget

1. Number of bathrooms: wet areas cost more per sq ft than bedrooms.
2. Staircase position: an internal staircase takes floor area; an external one is cheaper but less convenient.
3. Finish level: see basic vs standard vs premium.
4. Parking and boundary wall: often outside the per-sq-ft rate (see hidden costs).

Use the budget planner once you have a total in mind.
