Can we give the living room more space without increasing the footprint?

Q: Can we give the living room more space without increasing the footprint?

Yes — by moving one partition 300 mm. The living room goes from 27.2 m² to 28.8 m² and the study from 14.3 m² to 12.6 m². The outside walls, the entrance and the windows do not move, and the total named-room area is unchanged at 41.5 m². More living space, less study space. The outside footprint stays the same. This is a layout comparison; changes to an existing wall need a separate feasibility assessment.

One partition moves 300 mm. Nothing else does — same outside walls, same entrance, same three windows. Here is what that is actually worth, measured off the drawing rather than estimated.

The two layouts

Same footprint, one wall moved

Floor plan of the existing layout: an 8.4 by 6.0 metre outline with a study on the left and a living room on the right, divided by a partition with a door, the entrance and three windows marked — Existing layout as it is

The same floor plan with the partition moved 300 millimetres towards the study, giving the living room more floor area and the study less, with the outside walls, entrance and windows unchanged — More living space partition 300 mm west

Both plans are drawn at the same scale, so a bigger room looks bigger. The room areas printed on them are the ones the wall geometry gives — Gridsnap derives them from the walls themselves, and they change as you draw.

What changes

The tradeoff, in numbers

	Existing layout	More living space	Change
Living room area	27.2 m²	28.8 m²	+1.6 m²
Study area	14.3 m²	12.6 m²	−1.7 m²
Total named-room area	41.5 m²	41.5 m²	same
Wall length (centreline)	33.0 m	33.0 m	same

More living space, less study space. The outside footprint stays the same. This is a layout comparison; changes to an existing wall need a separate feasibility assessment.

Why it reads this way

A comparison is only worth as much as its numbers

The areas above are not estimates and they are not typed into this page. Gridsnap detects the rooms from the walls and reports the net floor area of each polygon, so moving the partition changes the numbers the way it changes the space — and the total stays the same, which is the honest answer: inside a fixed footprint, one room gains what another gives up.

The wall length is unchanged too, because the partition is the same length wherever it stands. That is the kind of thing a side-by-side is for: it tells you which differences are real and which ones you only imagined.

Open it

Free to inspect, free to download

Open this example in the editor and you get a read-only viewer: switch between the two layouts, put them side by side, look at either in 3D, and download the plan as a PDF. It opens on its own — nothing you have drawn is touched, nothing is saved to an account, and no sign-in is involved.

Drawing and exporting your own plans in Gridsnap is free. Creating and comparing Options within your own project — keeping the as-built and two alternatives as siblings, switching between them and comparing their numbers — is part of Gridsnap Pro.
