Bungalow Building: Process, Costs, Plot
Building a bungalow follows the same phases as any new build – but because of the single-storey construction it needs more plot and a larger floor slab. This guide leads step by step through the process in phases, explains the cost ranges (as of 2026) and the space requirement for the single-storey house. All price figures only as a range, objectively and with space benchmarks.
Building a bungalow follows the same phases as any new build — from buying the plot through the permit to the handover of the keys. Two things, however, are different with a single-storey house: because the living space is spread across one level, it needs a larger plot, and both the floor slab and the roof cover a larger area. This guide takes you step by step through building a bungalow, explaining the process, costs and plot requirement — all price figures given only as a range, as of 2026. An overview of models and fitting lines is provided by the page prefab bungalow. Anyone who wants to compare the house form itself, fittings and accessibility will find the details for the bungalow as a prefab house. What a typical design looks like is shown by the 120 sqm bungalow floor plan.
Building a bungalow: the process in phases
Short answer: Building a bungalow proceeds in clearly delineated phases: first come budget clarification, the plot search and checking the development plan (Bebauungsplan); then follow provider selection, floor-plan planning and the building application (Bauantrag). After the permit, the floor slab or basement is created, after which the manufacturer assembles the prefabricated wall and ceiling elements in just one to three days. Then follow the interior fit-out and building services, and finally acceptance and handover of the keys. From the building application to moving in, typically six to nine months pass.
Phases of building a bungalow with a prefab house (typical process, as of 2026)
| Phase | What happens | Duration (guide) |
|---|---|---|
| 1. Planning & budget | clarify budget, search for a plot, check the development plan | 2–6 months |
| 2. Provider & design | compare offers, plan the floor plan, contract | 1–3 months |
| 3. Building application | submission and official review | 2–4 months |
| 4. Floor slab / basement | earthworks, foundation, utility connection | 3–6 weeks |
| 5. Shell assembly | erecting the prefabricated elements | 1–3 days |
| 6. Interior fit-out & services | screed, heating, electrics, plumbing, fit-out | 8–14 weeks |
| 7. Acceptance & move-in | building acceptance, remaining work, handover of keys | 1–2 weeks |
The great advantage of prefabricated construction shows itself in phase 5: the weatherproof shell often stands after just one to three days, which noticeably reduces the weather risk and the construction time on site. Because with a bungalow everything is on one level, the staircase is dispensed with — but the footprint to be assembled is larger than with an equally sized multi-storey house. You are best off planning the floor plans using concrete templates from our floor-plan collection for bungalows.
The development plan decides on feasibility
The bungalow is single-storey — the development plan must allow that. In densely built-up residential areas, a two-storey construction is often required. So before buying the plot, check the permitted number of storeys, the site occupancy index and floor space index, and the building lines. In case of doubt, an early preliminary building enquiry with the municipality provides clarity.
Plot requirement and space needs for a bungalow
Short answer: Because the bungalow spreads its entire living space across one level, it needs a considerably larger plot than a two-storey house of the same living space. As a rule of thumb, 600 to 1,000 m² applies — the exact figure depends on the living space, the site occupancy index (Grundflächenzahl, GRZ) in the development plan and the setback areas to the neighbour. A 130 m² bungalow alone needs around 160 to 190 m² of built-up area, plus a terrace, driveway, parking space and garden. This drives up plot and connection costs.
Decisive is the site occupancy index (GRZ) in the development plan: it states what share of the plot may be built on. With a GRZ of 0.3, for example, only 30 percent of the area may be built on — for a bungalow with a large footprint this quickly becomes the limiting factor. Because the bungalow uses up the permitted footprint more than a multi-storey house, the space requirement is the central planning lever.
Space requirement of a bungalow by living space (guide values, single-storey, as of 2026)
| Living space | Built-up area (approx.) | Recommended plot |
|---|---|---|
| 80 m² | 100–120 m² | from 450 m² |
| 100 m² | 125–145 m² | from 550 m² |
| 120 m² | 150–175 m² | from 650 m² |
| 140 m² | 170–200 m² | from 750 m² |
| 160 m² | 195–225 m² | from 850 m² |
Guide values including an allowance for walls, terrace and roof overhang. The actual plot requirement depends on the GRZ, setback areas, driveway and parking spaces. As of 2026.

Building a bungalow: costs at a glance 2026
Short answer: A bungalow as a prefab house costs, turnkey in 2026 — depending on living space, roof shape and provider segment — within a wide range; there are no reliable flat prices. Per square metre, the bungalow is around 5 to 15 percent above a two-storey detached house, because the floor slab and roof cover a larger area. On top come the larger plot, the ancillary construction costs (15 to 20 percent) and the external works. All figures only as a range, as of 2026.
Cost ranges for building a bungalow by living space (as of 2026, turnkey, without plot)
| Living space | Entry segment | Mid segment | Premium segment |
|---|---|---|---|
| 80 m² | €230,000 – 265,000 | €265,000 – 295,000 | €295,000 – 325,000 |
| 100 m² | €280,000 – 315,000 | €315,000 – 350,000 | €350,000 – 385,000 |
| 120 m² | €330,000 – 365,000 | €365,000 – 400,000 | €400,000 – 435,000 |
| 140 m² | €380,000 – 415,000 | €415,000 – 450,000 | €450,000 – 480,000 |
| 160 m² | €420,000 – 450,000 | €450,000 – 485,000 | €485,000 – 510,000 |
Values without a plot and without ancillary construction costs (15 to 20 percent). Hip and pyramid roofs cost more than flat roofs. Only as a range, project-dependent, as of 2026.
How these ranges are composed in detail — from the floor slab through the trades to the ancillary construction costs — is broken down by the detailed guide building a bungalow: costs. You can work through the total price for your plot with the prefab house cost calculator; how each price factor works is shown on the page prefab house prices 2026. A major cost item is the floor slab: because with a bungalow it carries the entire living space, it turns out larger and thus more expensive than with an equally sized multi-storey house. A soil survey before signing the contract is a must.
Plot, floor slab and utility connection for a bungalow
Short answer: When building a bungalow, the plot and foundation account for a larger share of the cost than with a multi-storey house: the required plot is larger, the floor slab and earthworks cover a larger area, and the utility connection (water, wastewater, electricity, driveway) is spread over more metres too. So factor in the soil survey, surveying, development contributions and the ancillary construction costs early — otherwise the calculation gets out of balance.
- Soil survey (subsoil, load-bearing capacity, water table) before signing the contract.
- Floor slab or basement: more expensive with a bungalow due to the larger footprint.
- Utility connection: house connections for water, wastewater, electricity, possibly gas/fibre.
- Plan for surveying, site facilities and the driveway.
- Ancillary construction costs (notary, property transfer tax, permit): 15–20 percent.
- External works (terrace, paths, parking space, garden): from around €20,000.
Because the bungalow is at ground level, it can be planned almost entirely step-free — a plus for low-barrier living in old age. Anyone who wants to compare the house form with its pros and cons, roof variants and fitting lines will find all the details on the page bungalow as a prefab house. Neutral guidance on construction contracts and services descriptions is provided by the consumer advice centre (Verbraucherzentrale).
Avoiding typical mistakes when building a bungalow
Short answer: The most common mistakes when building a bungalow can be avoided with careful planning: a plot that is too small or poorly shaped, an overlooked stipulation in the development plan regarding the number of storeys, a floor slab budgeted too tightly, or forgotten connection and ancillary costs. Anyone who works through the plot requirement, the permit and the total costs early and honestly, and compares several offers on the same basis of services, builds considerably more relaxed.
With the plot, pay attention not only to the size but to the shape: a wide, rather shallow plot suits a bungalow better than a narrow, deep one. Also check whether the site occupancy index leaves enough scope for the large built-up area. And always compare offers via the construction and services description — only that way can you tell whether the floor slab, house connections and external works are already included.
Building a bungalow: well planned to a single-level home
Short answer: Building a bungalow proceeds in the same phases as any new build, but places special demands on the plot and foundation: more area, a larger floor slab and higher connection costs. Anyone who checks the development plan early, sets the space requirement realistically and works through the total costs including ancillary costs gets the greatest benefit from the single-storey house — a low-barrier, short-route home on one level.
Compare several offers on the same basis of services and have the process, costs and space requirement broken down transparently. A good basis is provided by our tool to compare prefab house manufacturers, the suitable templates from the floor-plan collection for bungalows and the overview of the bungalow as a prefab house. Anyone still wavering between single-level and multi-storey will find the decision aid in the comparison detached house or bungalow.
