Bungalow floor plans: single-storey living and comparing prices

From the compact 80 m² layout through the family bungalow and the L-shaped bungalow to the bungalow with a granny annexe: this is how you discover the right floor plan – and recognise which price your single-storey prefabricated house brings with it.

Quick answer

Which bungalow floor plan costs how much?

Bungalow floor plans spread all rooms across one level — without any stairs. Turnkey, the bungalow comes in at around €2,000 to €3,500/m² in 2026, per m² roughly 5 to 15 percent above a two-storey house, because the foundation slab and roof are built over a larger area. A compact 100 sqm floor plan for couples thus starts at around €280,000, a 120 to 140 m² family or L-shaped bungalow at about €330,000. A bungalow with a granny annexe costs more, but can be refinanced through rental income. Additionally factor in the larger plot of 600 to 1,000 m².

Common bungalow floor plans compared

Four floor-plan types cover most building wishes — from the compact two-person solution to the multi-generation bungalow. Area, room count and suitability make the initial orientation easier.

Single-storey prefabricated house bungalow with an open floor plan and a large terrace

3, 4 or 5 rooms: the room layout

The big advantage of a bungalow is the free arrangement on one level. The 3-room floor plan combines an open living-kitchen-dining area with a bedroom and a flexibly usable room as an office or guest room. The bungalow 4-room floor plan adds two children's rooms and a second bathroom — suitable for the young family. In the 5-room layout, a separate study or hobby room is added.

With the bungalow 120 sqm floor plan, clear zoning pays off: the living and dining area towards the terrace and garden, the bedrooms on the quiet side facing away from the street. You'll find further examples in our floor-plan overview.

What matters with a bungalow floor plan

Accessibility to DIN 18040-2

Step-free transitions, door widths from 90 cm and circulation spaces of at least 120 cm turn any bungalow into a barrier-free floor plan. A level-access shower bathroom and wide hallways secure senior-friendly living for the long term.

Check the plot and development plan

A bungalow needs 600 to 1,000 m² of plot. Before buying, clarify whether the development plan permits single-storey construction, the plot ratio and the roof form (flat, hipped or pyramid roof) for your desired floor plan.

Space for a granny annexe

A bungalow with a granny annexe creates a self-contained second unit for relatives or for letting. As a separate dwelling unit, it can also raise the KfW subsidy framework — provide for the separate entrance from the start.

How to plan your bungalow floor plan

Good bungalow floor plans start not with the façade but with everyday life. Anyone who keeps the routes between entrance, kitchen, living area and bedroom short gains noticeably in comfort — precisely because in a bungalow everything is on one level and no staircase connects the rooms. First, note down the daily routines: where does the shopping arrive, where does the centre of home life form, how much retreat do the bedrooms need? From these answers, it almost follows by itself whether a rectangular building volume or an L-shaped bungalow floor plan fits better.

The compact bungalow 100 sqm floor plan forms the entry point for couples and seniors: an open living-dining-kitchen area, a bedroom, a generous bathroom and a flexibly usable room. As the space requirement grows, the path leads to the bungalow 4-room floor plan with 120 to 140 m². The bungalow 120 sqm floor plan is considered by many self-builders to be a balanced compromise between space and cost: enough room for two children's rooms, a second bathroom and a guest WC, without plot and heating costs getting out of hand. Families wishing for clearly separated zones often choose the L-shaped bungalow, whose L shape creates a wind-protected courtyard.

A special case is the bungalow with a granny annexe. It combines the main dwelling with a self-contained second unit — for your own parents, an adult child or as a rental flat. Because a genuine second dwelling unit is created, the KfW subsidy framework can increase; the details are best clarified early with your provider and your bank. What is decisive is a separate, barrier-free access, so that both parties live independently of each other.

Plan the barrier-free floor plan in from the start — even if no one in the household is restricted today. The extra costs for step-free transitions, wider doors and a level-access shower bathroom are low in a new build, whereas a later conversion is expensive. The bungalow, as a single-storey house, is the most obvious building form for this forward-looking, senior-friendly living. Our guide to the barrier-free bungalow for seniors goes deeper into age-appropriate planning.

Before you commit to a layout, it's worth looking at the building form, costs and providers of the house type. All the basics — from the roof form through prices to suitable manufacturers — are summarised by our overview page on the bungalow as a prefabricated house. If you want to start with a concrete room programme, design your layout directly in the house configurator and then have suitable quotes from vetted providers sent to you. Among our 140 vetted providers and over 3.050 floor plans, there is a suitable template for almost every bungalow wish.

Modern prefabricated house bungalow with a flat roof and terrace in the evening – bungalow prefabricated houses and prices 2026
From the floor plan to the house: bungalow prefabricated houses range from the compact 80 m² couple's bungalow to the 140 m² family variant.

From the bungalow floor plan to the prefabricated house: prices & next steps

Once the desired floor plan is settled, the price question follows: prefabricated house bungalows come in, depending on size and fit-out, at around €2,400 to €3,400 per square metre in 2026 — a bungalow with a 120 sqm floor plan therefore comes in, turnkey, usually between €290,000 and €400,000, with compact 100 sqm bungalows correspondingly below that. Because of the larger roof and foundation-slab area per square metre of living space, bungalow prices are somewhat higher than for a two-storey house — but in return there is no staircase and no later conversion for living in old age. Current price ranges are given in the overview of the prefabricated house prices 2026; what "turnkey" specifically covers is explained by the guide building turnkey.

Bungalow floor plans: frequently asked questions

Answers to the most common questions about size, room layout, the L-shaped bungalow, the granny annexe and barrier-free planning.

How large should a bungalow floor plan be?
For a couple or singles, compact bungalow floor plans with 80 to 100 m² and 2 to 3 rooms are enough. Families realistically reckon on 120 to 140 m² and 4 to 5 rooms, so that children's rooms, a bathroom, a guest WC and a study can be accommodated. A bungalow 100 sqm floor plan is one of the most frequently chosen layouts, as it combines single-storey living with manageable costs. Because the bungalow accommodates everything on a single level, it feels more generous than a two-storey house for the same square footage — but it also claims more plot area.
What is an L-shaped bungalow and when is it worth it?
An L-shaped bungalow (Winkelbungalow) is laid out in an L shape: one wing of the building houses the open living, dining and kitchen area, the other the bedrooms and children's rooms. This L-shaped bungalow floor plan clearly separates the quiet and living zones and creates a wind-protected courtyard or a terrace in the corner of the L. It is particularly worthwhile for families from 120 m² and on plots that allow a compact, wide layout. The disadvantage: more external wall area entails somewhat higher construction and heating costs than a rectangular building volume.
How do you plan a barrier-free bungalow floor plan?
A barrier-free floor plan follows DIN 18040-2: step-free transitions, door widths from 90 cm, circulation spaces of at least 120 cm (wheelchair-accessible 150 cm) in front of sanitary fittings, and a level-access shower bathroom. Since the bungalow arranges all rooms on the ground level anyway, it forms the ideal basis for senior-friendly and wheelchair-suitable living. Wide hallways, an easily reachable kitchen and a bedroom close to the bathroom are also recommended. Our guide to the barrier-free bungalow provides the details.
How much plot does a bungalow need?
Because the bungalow spreads its entire living space across one level, the plot requirement is higher than for a multi-storey house: 600 to 1,000 m² is realistic, depending on living space, the plot ratio (Grundflächenzahl, GRZ) and the separation distances to the neighbour. A bungalow with 120 m² of living space quickly takes up 700 to 850 m² including terrace, driveway and garden. Before buying a plot, be sure to check the development plan — it must expressly permit single-storey construction.
What does a bungalow cost as a prefabricated house in 2026?
A bungalow as a prefabricated house comes in, turnkey, at around €230,000 (80 m²) to €520,000 (180 m²) in 2026, excluding the plot. Per square metre, the bungalow is around 5 to 15 percent above a two-storey single-family house, because the foundation slab and roof are built over a larger area. A bungalow with a granny annexe costs accordingly more, but can partly offset the extra outlay through rental income or a subsidised second dwelling unit. Values excluding plot and ancillary building costs (15 to 20 percent), as of 2026.
