What direction should hardwood planks run in a Calgary split level home?

In a Calgary split-level home, hardwood planks should generally run parallel to the longest wall or the primary sight line from the main entrance, but split-levels present unique challenges because of the half-level transitions and stairways that interrupt the floor plane.

The standard rule of thumb is to install hardwood parallel to the longest dimension of the room or perpendicular to the floor joists (which provides the strongest structural connection for nail-down installations). In most Calgary split-levels — whether they are the classic 1960s-1970s designs common in communities like Lake Bonavista, Braeside, Woodbine, and Dalhousie, or the updated versions in newer developments — the main living area is rectangular, and running planks along the long axis makes the space feel larger and more cohesive.

The split-level challenge is that you have two or three floor levels connected by short stairways, and the hardwood direction needs to work on all levels for visual continuity. Here is the practical approach: choose the direction based on the largest, most visible level — typically the main living room and kitchen area. When you transition to the upper or lower half-level, maintain the same plank direction if at all possible. This creates visual flow when you look across the stairway transition from one level to another. Changing direction between levels looks disjointed and is a common aesthetic mistake in split-level renovations.

At the stairway transitions, a professional installer will handle the direction change using transition strips or custom nosing pieces that create a clean visual break. If the stairway runs perpendicular to the plank direction, the transition looks natural. If the stairway runs parallel to the planks, the nosing and trim work requires more craftsmanship to look right.

For structural reasons, if you are doing a nail-down installation over plywood subfloor, the planks should ideally run perpendicular to the floor joists for maximum holding power. In many Calgary split-levels, the joist direction may differ between levels because the framing changes at the step-down. If this is the case, and the joists on one level run the opposite direction, a layer of 3/8-inch plywood underlayment can be added to allow the planks to run in your preferred direction regardless of joist orientation.

Hallways are another consideration in split-levels. If a hallway connects two levels, run the planks along the length of the hallway — planks running across a narrow hallway look chopped up and make the space feel even narrower. This may mean the hallway planks run at a different angle than the rooms they connect, which requires a transition strip at each doorway.

Light direction matters too. In Calgary, where natural light is abundant and enters at a low angle during winter months, planks running toward the main window source show seams and imperfections less than planks running parallel to the light. South-facing rooms with large windows are particularly sensitive to this.

A skilled installer will walk through your split-level, consider the joist direction, sight lines, stairway transitions, and natural light, and recommend the optimal layout.
