# Long narrow living room layout: keep the route clear

Map the route between doors first, then fit the seating beside it. In a narrow room, add furniture depths and the gaps between them across the short dimension before deciding whether the arrangement works.

## Treat the short dimension as a budget

A long room can have plenty of area but very little width where people pass. Start with the clear inside width after radiators, fireplace projections and fixed cabinetry. Then account for every object across that width.

For an assumed 3000 mm-wide room, the following arrangement uses the entire width. The gaps are scenario assumptions for comparison, not prescribed clearances. Test them with the actual furniture and the people using the room.

| Part across the room | Assumed depth or gap |
| --- | --- |
| Sofa | 900 mm |
| Sofa-to-table gap | 450 mm |
| Coffee table | 500 mm |
| Walking route | 850 mm |
| Media unit | 300 mm |
| Total | 3000 mm |

## Choose which side carries through traffic

If the doors line up along one side, put the main route on that side rather than routing everyone between the sofa and coffee table. If an entry opens into the middle of the long wall, test two smaller zones so the entry does not cut a conversation group in half.

Check the TV and seating relationship separately. This example establishes whether the objects and route can fit across the room; it does not calculate the right viewing distance for your screen or guarantee a comfortable viewing angle.

## Compare three changes without changing the room

| Change | What it buys | What to check |
| --- | --- | --- |
| Use a 350 mm-deep table instead of 500 mm | 150 mm more width to allocate | Useful tabletop area |
| Remove the media unit | 300 mm of floor depth | Actual equipment and cable arrangement |
| Create a reading zone at the far end | A separate use for extra length | The route between zones stays connected |

## Draw and review the bottlenecks

FloorDraft can help reveal overlapping furniture, but a collision-free outline is not a complete movement check. Inspect the route while chairs are pulled out and doors are open, then confirm it in the room.

1. Draw the room and the openings at measured positions.
2. Place the sofa and media unit at their real depths.
3. Add the table, then annotate the remaining gaps.
4. Follow the route from entry to the next door, including turns and door swings.
5. Compare a second arrangement using the same furniture dimensions.

## Questions

### Should every piece go against a wall?

No. Floating a piece may help define a zone, but only if the remaining route works. Decide from the measured width and openings.

### Does a smaller coffee table solve every narrow room?

It can recover width in the seating zone. It will not solve an entry door that collides with the sofa or a blocked route at the far end.
