Floor Plan Bungalow 120 sqm: Room Layout at a Glance

Short answer: A floor plan bungalow 120 sqm offers single-story space for three to four rooms: an open living-dining-cooking area of around 45 to 55 sqm, a parents bedroom, one to two child or work rooms, a barrier-free bathroom and a guest WC. Currently you can find 22 bungalows between 110 and 135 m² with us, the cheapest from 271.000 € catalogue starting price. These manufacturer prices apply without building plot and ancillary construction costs.

The major advantage of the bungalow is the stair-free, barrier-reduced living - convenient in everyday life and long-term future-proof. The 120 sqm counts as the family sweet spot: Compared to the Floor Plan Bungalow 100 sqm you gain around 20 sqm - enough for a fourth room, a small parents suite with dressing room or a second bathroom. Smart zoning remains important: an open living area as the heart, a quiet sleeping tract and sufficient storage space via a utility room, which becomes particularly important when dispensing with the basement.

Area Distribution: How the 120 sqm is divided among the rooms

The following distribution is a proven guideline for a 4-room family layout. It shows how much area the individual zones typically require. Depending on room count, angle or parents suite the values shift - the living center remains almost always the largest item with around 40 percent of the living area.

Example area distribution of a 120-sqm bungalow (4-room variant, guideline values)

Room / ZoneArea (guideline value)Share of 120 sqm
Living / Dining / Cooking48 m²40 %
Parents Bedroom16 m²13 %
Child/Work Room (2×)24 m²20 %
Bathroom + Guest WC13 m²11 %
Hallway / Entrance11 m²9 %
Utility Room / Technology8 m²7 %

Those who plan three rooms instead of four usually shift the freed up around 12 sqm mostly into the living center or into a parents suite with dressing room. Conversely with very compact rooms a second bathroom can also be planned in. Clarify details on layout and furnishing best early with the architect or the prefabricated house provider.

L-shaped Bungalow or Rectangular Bungalow at 120 sqm?

The rectangular bungalow is the most compact and usually cheapest variant: simple statics, little external wall area and also implementable on narrower building plots. At 120 sqm the L-shaped bungalow plays its strength: The L-shaped floor plan arranges the rooms so that living and sleeping tract are clearly separated - in the angle center a protected inner courtyard or a terrace is created. For families with four rooms the angle is often the quieter solution, caused by the larger envelope area but somewhat higher construction and heating costs. More on this in L-shaped Bungalow Floor Plan and in the Bungalow Floor Plan Overview. The complete topic overview for single-story living is bundled by the Prefabricated House Bungalow.

In our current selection the catalogue from prices range from 271.000 € to 508.000 € — the range is explained primarily by fit-out stage, equipment, basement option and energy standard. Always add to the house price building plot, development, building permit and external facilities - how this works is shown by the Guide to House Construction Costs. Whether basement or floor slab is more sensible clarifies the comparison Basement or Floor Slab.

120 sqm in Comparison to 100 and 140 sqm

The choice of living area is always a compromise from need, budget and building plot size. The 100-sqm bungalow is the compact solution for couples and small families, the 140-sqm bungalow offers generous rooms with separate parents bathroom. The 120 sqm lies exactly in between and counts as the most balanced family layout.

Those who calculate tighter look at the Floor Plan Bungalow 100 sqm ; those who want more area and a parents bathroom plan more generously and orient themselves to the Floor Plan with 120 sqm across all house types. Suitable bungalow houses with in-law apartment - for example for the parent generation or as rental option - you will find under Bungalow with In-Law Apartment: Floor Plan.

Checklist: Cleverly plan 120 sqm bungalow floor plan

On one level, room count, zoning and barrier-free accessibility determine living comfort. These points help to use the 120 sqm optimally:

  • Determine number of rooms: Should it be three large or four more compact rooms? The 120 sqm allow both.
  • Choose zoning: Rectangular bungalow (compact, affordable) or L-shaped bungalow (clear separation living/sleeping)?
  • Consider barrier-free: threshold-free transitions, door widths from 90 cm, level-access shower and 1.50-m movement areas.
  • Plan parents area: With 120 sqm a small parents suite with dressing room or a second bathroom is realistic.
  • Consciously decide between basement or floor slab – at 120 sqm the floor slab is usually the more affordable option.
  • Plan storage space: generous utility room and built-in cabinets replace the missing basement.
  • Check building plot and floor area ratio (GRZ): The 120-sqm bungalow needs more area than a multi-story house.
  • Never confuse catalogue from price with total costs – calculate building plot and 15–20 % ancillary construction costs separately.

Frequently asked questions on the 120 sqm bungalow floor plan

Answers regarding room layout, number of rooms, L-shaped bungalow, building plot requirement, barrier-free accessibility and costs 2026.

How is a 120 sqm bungalow floor plan typically divided?
A 120 sqm bungalow floor plan distributes all rooms on one level: The center is an open living-dining-kitchen area of about 45 to 55 sqm with terrace access, plus three to four rooms (parents bedroom, child or office room), a bathroom with level-access shower, a guest WC and a utility room. The 120 sqm offer noticeably more leeway compared to the 100 sqm bungalow for a dressing room, a second bathroom or a real family dining table – ideal for families and couples with home office.
How many rooms fit into a 120 sqm bungalow?
In a bungalow with 120 sqm realistically three to four rooms plus open living area fit. A family usually sets up one parents bedroom and two child rooms and keeps a fourth room as work or guest room. Those who want more living and dining space reduce to three rooms and enlarge the center. With the L-shaped bungalow the living and sleeping tracts can be cleanly separated, which ensures peace in the sleeping area with four rooms.
How does the 120 sqm bungalow differ from the 100 and 140 sqm bungalow?
The 100 sqm bungalow is the compact solution for couples and small families with three rooms. At 120 sqm you gain about 20 sqm – enough for a fourth room, a dressing room or a second bathroom, without greatly increasing the building plot requirement. The 140 sqm bungalow then offers spacious rooms, often a separate parents bathroom and more storage space, but costs more accordingly and needs a larger building plot. 120 sqm is considered a balanced family sweet spot.
How much building plot does a bungalow with 120 sqm need?
Since the bungalow accommodates its entire living area on one level, the plot requirement is higher than for the multi-story house: Realistically 600 to 850 sqm, depending on floor area ratio (GRZ), terrace, driveway, garage and garden. Definitely check the development plan before purchasing the plot – it must explicitly permit single-story construction. An L-shaped bungalow tends to need a somewhat wider or corner plot than the compact rectangular form.
What does a bungalow with 120 sqm as prefabricated house cost in 2026?
At the 2026 price level of around 2,350 €/m² (volume house) to 4,500 €/m² (premium) a turnkey 120 sqm bungalow is about 282,000 € to 540,000 €, without basement and plot. Bungalows cost about 5 to 15 percent more per square meter than a two-story house because floor slab and roof are created on a larger base area. As a shell house for self-finishing with personal contribution the price drops; ancillary building costs of 15 to 20 percent are added in each case.
L-shaped bungalow or rectangular bungalow at 120 sqm?
The rectangular bungalow is more compact, cheaper and easier to implement on narrow plots. At 120 sqm the L-shaped bungalow plays out its strength: The L-shaped floor plan separates the living from the sleeping tract and creates a wind-protected inner courtyard or a terrace in the corner. For families with four rooms the angle is often the quieter solution but costs somewhat more in construction and heating due to the larger external wall area.
Can a 120 sqm bungalow be planned as barrier-free?
Yes, the bungalow is the most barrier-free house type, because all rooms are without thresholds on one level. At 120 sqm there is enough space to plan for door widths from 90 cm, a level-access shower, sufficient movement areas of 1.50 m in the bathroom and hallway as well as a step-free terrace. Anyone who wants to build age-appropriately should consider these dimensions from the beginning in the floor plan - subsequent adjustments are significantly more expensive.
