About this layout

This layout uses the split-bedroom arrangement common in single-storey family homes: the primary suite sits on one side of the plan and the three secondary bedrooms cluster on the other, with the shared living, dining and kitchen zone between them. The separation is what makes four bedrooms workable in about 1,650 sq ft — the primary suite gets genuine acoustic privacy without needing a second floor, and the kitchen island becomes the natural centre of the house rather than a bottleneck.

Design tips

Keep at least 3.5 ft clear on every side of the island, and 4 ft on the side you cook from where two people are likely to pass.
Put the laundry on the secondary bedroom side of the plan, not off the kitchen — it shortens the trip that actually gets made daily.
Give the primary suite its own door off the living zone rather than off a hall shared with the other bedrooms.
Size the secondary bedrooms identically where you can; unequal rooms in a family home become a recurring negotiation.
Set the dining table on the axis between the island and the living room so the three spaces read as one connected sequence.

Recommended furniture and dimensions

Sized for a family of four to six. The island and dining table are the two pieces whose clearances set the room dimensions.

Living Area

Item	Dimensions	Why this size
3-Seater Sofa	7.0–7.5 ft (W) × 3.0 ft (D)	Faces the media wall with the dining table behind it.
Media Console	6.6–7.2 ft (W) × 1.3 ft (D)	Sized to sit under a 65–75 in screen without looking undersized beneath it.

Dining Area

Item	Dimensions	Why this size
6-Seater Dining Table	5.9–6.6 × 3.0–3.3 ft	Allow 3 ft clear on all four sides before the walkway or a wall begins.
Dining Chairs	~1.6 ft (W) each	Two per long side plus one at each end.

Kitchen

Item	Dimensions	Why this size
Kitchen Island	6.6 × 3.3 ft	Takes three stools on the seating side with a 12 in counter overhang.
Perimeter Run	12–14 ft, 2.0 ft (D)	Carries the range along the wall; the sink sits in the island.
Counter-Depth Fridge	3.0 ft (W) × 2.0 ft (D)	Counter depth keeps the run flush so the island clearance stays even.

Primary Suite

Item	Dimensions	Why this size
Queen Bed	4.9 × 6.6 ft	Centred on the wall so both sides keep a 2 ft access strip.
Walk-In Closet	6 × 8 ft	Hanging rails on two walls with a 3 ft aisle between them.

Secondary Bedrooms (3)

Item	Dimensions	Why this size
Double or Twin Bed	4.5 × 6.3 ft / 3.2 × 6.3 ft	Twins let a shared room take two beds with a 3 ft aisle between them.
Wardrobe	4.0–5.0 ft (W) × 2.0 ft (D)	Built-in where possible so the room keeps its full nominal width.

Colour and lighting

Colour scheme

Keep the shared zone in a single warm neutral so the long sightline from the living room to the kitchen stays calm, and let the secondary bedrooms carry stronger colour where they are used by children.

Lighting notes

Pendants over the island and the dining table, recessed ambient light across the living room, and a separate low-level circuit in the bedroom halls. Give the primary suite bedside switching independent of the ceiling light.
