Bungalow or two-story single-family house? Duplex house or shell house for self-finishing? Solid or prefabricated? Anyone facing the decision for a new home quickly loses track of the options.

This guide leads you like a decision tree through the five decisive questions - budget, building plot, life phase, construction method and finishing stage. At each fork we point to the suitable house type pages so that in the end you know which direction is sensible for you. A self-test does not replace a personal consultation but provides a robust initial orientation. For the exchange with other interested builders our House construction forum, a first impression on site is provided by the 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 capital and the monthly affordable installment, from this the financing framework results. In addition to the house price calculate about 15 to 20 % for construction ancillary costs and if applicable the building plot. Only when the overall framework is set can a sensible decision be made about size, construction method and finishing stage - otherwise you plan past reality.
First get an overview of the overall costs. The House construction costs guide and the Cost calculator provide reference values for 2026. The guide explains what amount of equity is sensible Equity for house construction. If the budget is tight two paths continue: more own work via a shell house for self-finishing or a compact, favorable layout according to the guide Build affordably.
Step 2: Which building plot do you have or are you looking for?
Short answer: The building plot largely determines what may be built. Cut, size, slope location and the specifications of the development plan (for example number of floors, roof shape and buildable area) strongly limit the possible house types. A small building plot tends to speak for a duplex house or a two-story house, a large flat building plot also allows a sprawling bungalow. Clarify these framework conditions before you commit to a house type.
If you are still looking, the guide helps Find & evaluate building plot. On small parcels the duplex house is often the most economical solution - how it can be implemented as a prefabricated model is shown in the guide Prefabricated house duplex. On generous plots the bungalow is an option, those who prefer it more representative find numbers in the guide Build city villa: costs. Suitable offers by region can be found in our Regions.
Step 3: In which life phase are you building?
Short answer: The life phase decides on size and floor plan. Families with children need several rooms, storage space and a garden - a classic single-family house fits here. Couples or singles get by with more compact forms. Those who want to live age-appropriate and low-barrier are well advised with a ground-level bungalow. Think not only of today but of the next 15 to 20 years - an adaptable floor plan pays off in the long term.
House type by life phase (orientation)
| Life situation | Suitable house type | Why |
|---|---|---|
| Family with children | Single-family house | several rooms, garden, storage space |
| Couple / single | compact house / duplex half | economical, less area |
| Older / low barrier | Bungalow | ground level, one story |
| Multigenerational | House with ancillary apartment | separate areas under one roof |
| Second residence / weekend | Vacation house | compact, weatherproof |
For the house types you will find your own hubs, for example the single-family house for families or the vacation house as second residence. Families additionally read the guide Prefabricated house for families.

Step 4: Prefabricated or solid construction?
Short answer: Both construction methods lead to a good house - the choice depends on your priorities. The prefabricated construction scores with short, plannable construction time, fixed price and high energy efficiency from the factory. Solid construction is regarded by many as particularly robust and offers advantages in storage mass with individual planning. For resale value both are similar with good execution. Those who want to build quickly and with high cost certainty tend more towards the prefabricated house.
The guide deals with the differences in detail Prefabricated house vs. solid brick house; a structured decision aid is offered by the guide Choose construction method. Those deciding for solid find basics in the hub solid brick house, those preferring prefabricated construction in the hub timber house. A sound introduction to the topic is offered by our Prefabricated house at a glance.
Doubts about the construction method? Check myths
Many construction decisions are based on prejudices instead of facts. Before you commit, it is worth a look at the prefabricated house myths guide - there we classify claims such as "lasts only 50 years" or "solid is always more value stable" in a factual manner.
Step 5: How much do you want to do yourself?
Short answer: The fit-out stage is the last major lever. A turnkey house is handed over ready to occupy and is the most comfortable, but the most expensive. A shell house for self-finishing leaves the interior fit-out to you and lowers the price, however requires time and manual skills. A kit is the most affordable, but only sensible with a lot of own contribution. Choose realistically: Overestimated own contribution leads to delays and additional costs.
- Turnkey: maximum comfort, highest price, little own effort.
- Technically finished / shell house for self-finishing: medium price, interior fit-out by own contribution.
- Kit: most affordable entry, very much own contribution and time necessary.
- Assess honestly: available time, craft skills and helpers.
- Define own contribution in writing to avoid interface problems.

Short answer: To summarize: Tight budget and time available leads to the shell house for self-finishing; small building plot to the semi-detached house; low-barrier living to the bungalow; family with children to the single-family house; desire for fast construction time and fixed price to the prefabricated house.
