Which House Suits Me? The Self-Test in Five Steps
Bungalow or detached house, solid or prefab, turnkey or shell house? This decision aid leads you like a decision tree through five key questions: budget, plot, life stage, construction method and finishing stage. At each fork, recommendation paths follow to the matching house types.
Bungalow or two-storey detached house? Semi-detached house or shell house? Solid or prefab construction? Anyone facing the decision about a new home quickly drowns in options. The good news: with a clear order, you can deliberately narrow down the choice. This guide leads you like a decision tree through the five decisive questions – budget, plot, life stage, construction method and finishing stage. At each fork, we point to the relevant house-type pages so that, in the end, you know which direction makes sense for you. A self-test doesn't replace personal advice, but it gives you a robust first orientation. To exchange ideas with other prospective builders, our house-building forum is also worthwhile, and a first impression on site is provided by a show-home park visit.
Step 1: How much budget is realistically available?
Short answer: The budget is the most important starting point. First determine your available equity and the monthly rate you can afford; from this comes your financing framework. In addition to the house price, budget around 15 to 20% for ancillary construction costs (Baunebenkosten) and, if applicable, the plot. Only once the overall framework is set can you sensibly decide on size, construction method and finishing stage – otherwise you're planning past reality.
First get an overview of the total costs. The house-building cost guide and the cost calculator provide guide values for 2026. How much equity makes sense is explained in the guide equity for house building. If the budget is tight, two routes lead further: more contributed labour via a shell house or a compact, low-cost layout following the guide building on a budget.
Step 2: Which plot do you have or are you looking for?
Short answer: The plot largely determines what may be built. Layout, size, sloping location and the requirements of the development plan (Bebauungsplan) – such as number of storeys, roof shape and buildable area – strongly narrow down the possible house types. A small plot tends to favour a semi-detached or a two-storey house, while a large level plot also allows a spread-out bungalow. Clarify these framework conditions before you commit to a house type.
If you're still searching, the guide find & assess a plot helps. On small parcels, the semi-detached house is often the most economical solution – how it can be implemented as a prefabricated model is shown in the guide prefab semi-detached house. On generous plots, the bungalow is an option, and anyone who prefers something more prestigious will find figures in the guide building a town villa: costs. You'll find suitable offers by region in our regions.
Step 3: In which life stage are you building?
Short answer: The life stage decides on size and floor plan. Families with children need several rooms, storage space and a garden – a classic detached house fits here. Couples or single people manage with more compact forms. Anyone wanting to live age-appropriately and with few barriers is well advised to choose a single-storey bungalow. Think not only of today, but of the next 15 to 20 years – a floor plan that grows with you pays off in the long run.
House type by life stage (orientation)
| Life situation | Suitable house type | Why |
|---|---|---|
| Family with children | Detached house | several rooms, garden, storage |
| Couple / single | compact house / semi-detached half | economical, less floor area |
| Older / low-barrier | Bungalow | single-storey, one level |
| Multi-generation | House with granny flat | separate areas under one roof |
| Second home / weekend | Holiday house | compact, weatherproof |
Each house type has its own hub, such as the detached house for families or the holiday house as a second home. Families should additionally read the guide prefab house for families.

Step 4: Prefab or solid construction?
Short answer: Both construction methods lead to a good house – the choice depends on your priorities. Prefab construction scores with a short, plannable build time, a fixed price and high energy efficiency from the factory. Solid construction is seen by many as particularly robust and offers advantages in thermal mass with individual planning. In terms of resale value, the two differ little with good execution. Anyone wanting to build quickly and with high cost certainty tends towards the prefab house.
The differences in detail are covered by the guide prefab house vs. solid construction; a structured decision aid is offered by the guide choosing a construction method. Anyone deciding on solid construction will find fundamentals in the hub solid house, and anyone preferring prefab in the hub timber house. A well-founded introduction to the topic is offered by our prefab house overview.
Doubts about the construction method? Check the myths
Many construction-method decisions rest on prejudices rather than facts. Before you commit, it's worth a look at the prefab-house myths guide – there we objectively classify claims such as "only lasts 50 years" or "solid is always more value-stable".
Step 5: How much do you want to do yourself?
Short answer: The finishing stage is the last big lever. A turnkey house is handed over ready to move into and is the most comfortable, but the most expensive. A shell house leaves the interior fit-out to you and lowers the price, but requires time and DIY skills. A kit house is the cheapest, but only makes sense with a lot of contributed labour. Choose realistically: overestimated own labour leads to delays and additional costs.
- Turnkey: maximum comfort, highest price, little own effort.
- Technically finished / shell house: mid-range price, interior fit-out through own labour.
- Kit house: cheapest entry, a great deal of own labour and time needed.
- Assess honestly: available time, DIY knowledge and helpers.
- Delimit own labour in writing to avoid interface problems.
Details are provided by the guides finishing stages, building turnkey and contributed labour in house building.
The recommendation paths at a glance
Short answer: To summarise: a tight budget with time available leads to the shell house; a small plot to the semi-detached house; low-barrier living to the bungalow; a family with children to the detached house; the wish for a quick build time and fixed price to the prefab house. These paths are orientation aids, not rigid rules – often the best solution only emerges in conversation with several providers and when visiting show homes.
Before you commit, it's best to inspect several houses. The show-home checklist and the overview of show homes help with this. Once you have your answers, you can request suitable manufacturers in a targeted way in the quote comparison.
