Designing a living room in a Vietnamese tube house (narrow townhouse) is always a challenge: the floor plan is narrow, deep and starved of light in the middle. The key is not how many square metres you have, but how you compose volumes, colours and furniture so the reception space feels compact, airy and characterful all at once. Here are nine townhouse living room ideas that work for both 4 m and 5 m frontages.

Why are tube houses difficult?

Tube houses (urban townhouses) are defined by a narrow width (typically 3.5–5 m), a long depth and daylight only at the two ends. The living room sits right at the street frontage, so it must both receive guests and act as the “face” of the whole house. Three constraints to solve:

  • Narrow width: furniture easily blocks circulation and makes the room feel cramped.
  • A dark middle zone: the deeper you go, the darker it gets — unless you open a void or skylight.
  • Overlapping functions: living, kitchen and dining usually share a single axis.

Ideas for a 4 m-wide townhouse living room

Four metres is genuinely tight, so prioritise visual tricks and squeeze value from every square metre:

  • Connect living–kitchen–dining: remove solid dividing walls and use a half-height partition or kitchen island for soft zoning, keeping sightlines open end to end.
  • A light base palette: white, cream and pale grey with warm brown timber furniture makes the space feel both larger and more welcoming.
  • A compact sofa against the wall: favour a two-seat settee or a small L-shaped corner sofa, keeping walkways at least 60–75 cm clear.
  • Brass and gold metallic accents: a few metallic touches on lights, frames or table legs over the neutral base add refinement without visual noise.

Ideas for a 5 m-wide townhouse living room

One extra metre of width opens far more layout options:

  • An open living–dining flow: centre a brown-toned sofa set around a timber coffee table, with the dining zone continuing behind to create depth.
  • High ceilings with layered lighting: combine ceiling lights, cove lighting and decorative fixtures for both effect and proper light in every zone.
  • A feature wall: a panel of stone, timber cladding or deep paint behind the sofa gives the living room a clear visual anchor.
  • Permeable partitions: open shelving, timber slats or glass instead of solid walls divide zones while letting light pass through.

3 principles that always apply

Whether the house is 4 m or 5 m wide, these three principles keep a townhouse living room beautiful and liveable:

  1. Light comes first: exploit the front facade, skylights and double-height voids; use light-coloured floors and ceilings to bounce daylight deeper into the plan.
  2. Multifunctional, wall-hugging furniture: built-in cabinets, wall shelving and storage-integrated tables free up floor area.
  3. Keep one clear circulation axis: never place furniture across the main route from the front door inward.

Good ideas are only complete when built correctly

A townhouse living room scheme that looks good on paper only delivers when built to spec: the right ceiling heights, the right light positions, the right cladding materials. This is where a single-point general contractor matters — consolidating electrical, plumbing, air conditioning, lighting and finishing under one roof to avoid the “drawn one way, built another” problem.

AIC works to a single-point design-build model, with over 10 years in the trade (since 2016 under the predecessor Nhân Việt; AIC was founded in 2019) and two in-house factories (1,200 m² and 600 m²). From a floor plan, AIC can produce a BOQ estimate within roughly 4 working hours so homeowners can size their budget; projects are handed over with a warranty of up to 24 months.

Frequently asked questions

How do I design a living room in a 4 m-wide tube house so it doesn’t feel cramped?

Use a light base palette, open up the living–kitchen–dining flow to avoid chopping the space, choose a compact sofa placed against the wall and keep walkways at least 60–75 cm clear. Maximise light from the front facade and skylights to visually stretch the depth.

Which style suits a townhouse living room?

Modern and minimalist are the two safest choices for tube houses because they carry few fussy details and keep the space tidy. For extra warmth, combine brown timber furniture with a few metallic accents or a stone/timber feature wall behind the sofa.

Should the wall between the living room and kitchen be removed in a tube house?

In most cases, yes. Replacing the solid wall with a half-height partition, kitchen island or open shelving lets light travel deeper and makes the space feel visually larger — while still zoning each function clearly.
