ᐅ Beginner Questions About Building a House

Hello everyone!

After reading here for a while, I’ve now decided to actively participate (with questions! Unfortunately, my knowledge isn’t enough to provide answers).

Who we are:
A brief introduction: we are a family of six facing a move due to work. It doesn’t need to happen immediately. Currently, my husband commutes and the pressure isn’t very high. In the medium term, however, we would like to relocate closer to his job.

We’re not firmly set on building a house, but after watching the market for some time, we’ve realized that we either have to rent a rundown place, spend an enormous amount of money, or hope for a lucky find. Unfortunately, the housing market is not designed for large families. Almost all listings are poorly laid out or too small. Sometimes suitable homes do appear, but often we’re simply too slow due to distance. The same goes for buying existing houses. Somehow, the market seems pretty depleted.

As a sort of Plan B, we’re now considering building and are starting to explore that slowly. We’re (still!) complete beginners and have little clue, so I’m hoping for answers to many basic questions here.

What we are looking for:
We don’t need luxury but want to plan thoughtfully (eventually the children will leave home), aiming for reasonable energy efficiency and, if possible, a clear, simple architectural style. Specifically, a house without unnecessary frills. Ideally designed as a house with “two separate living units.” Not only to potentially benefit from double government subsidies (such as the KFW building loan program / similar grant schemes, though as a layperson I don’t fully understand or know if those loans are really top priority—probably a topic to revisit later)—but also to avoid living in a house that’s too large once the kids have moved out.

We want to build affordably but not cheaply. That means carefully considering what is truly needed, keeping things simple and pared down, and (in many but not all areas) opting for relatively basic finishes. We currently live in a (very well planned!) house of about 140 sqm (1500 sq ft). In our opinion, more space isn’t necessary with good design.

How much will it cost?
I keep running into cost-per-square-meter figures related to building. It’s often stated that you can build for around €1100 (about $1200) per sqm (simple finishes), up to €2000 (about $2200) for higher-end finishes (with no clear upper limit). But I wonder: can you really build a decent house for €1500 (about $1650) per sqm? From browsing various prefab home catalogs, that seems too low to me. But I’m happy to be proven wrong.

Cost calculation:
We don’t want to rush into building just for the sake of it. Right now, we’re mainly considering whether we can afford to build at all. Here is a rough example calculation running through my mind for you to review. Please: where is the mistake? What have I overlooked?

House, 150 sqm (1600 sq ft) - €225,000 (about $247,000)
Plot, fully serviced (picked at random—some can be cheaper, some much more expensive) - €35,000 (about $38,000)
Additional construction costs (according to this forum) - €40,000 (about $44,000)
Garden - €10,000 (about $11,000) (probably underestimated, but this is an area where we can do a lot ourselves)
Contingency for unexpected costs / overruns / whatever - €10,000 (about $11,000)
Contingency for extras (e.g., a new kitchen or carport) - €10,000 (about $11,000)
———
Total: €320,000 (about $351,000)

Architect fees are not included yet. I have no idea what they might cost.

If I enter this into a mortgage calculator, it produces an offer (loan amount minus our equity) with a 15-year term at 2% effective annual interest rate for about €900 (about $980) per month.
Besides the KFW option, there is also the possibility of a loan from the Investment and Structural Bank RLP for €125,000 (about $137,000), also with a 15-year term at 2.0% or 10 years at 1.6%. Not really cheaper, but prepayments of 10% per year are allowed. This is interesting for us because a second income will come in a few years, which we won’t fully need for living expenses (currently one income suffices).

I find this incredibly affordable and wonder: what am I missing? Where’s the catch? If this calculation is even remotely realistic, building a house would be quite manageable.
If you factor in about €400 (about $440) per month for utilities and other running costs, we’d be paying about the same as we do in rent now. In a newly built home close to the job, daycare fees would be eliminated (saving about €250 (about $275) per month) and my husband’s commuting costs would roughly halve (saving another €250 (about $275)). So we would have about €500 (about $550) extra per month to save.

Currently, we live on one income. In no more than five years, a second income will be added. By the time the loan term ends, at least two, more likely three children will be out of the house, so the “granny flat” or second unit could be rented out.

More generally, I’m wondering how to approach this sensibly. How do I find someone who would build for the prices mentioned above (if it’s financially doable)? If we build, it will be securely financed. Of course, that probably means no more three vacations a year. But the children should still be able to continue horse riding or music lessons. How can I get an overview of this complicated market? Is there a good book on the subject? Or any other tips for our first steps?

Thank you very much already,

kauderwelsch (That’s exactly how building feels to me right now)

You don’t need an architect if the general contractor designs the house. However, this is usually included in the fixed price.

@Nordlys

I agree with you to some extent. But which general contractor offers a standard floor plan with five bedrooms within 150m² (1,615 sq ft)? In such cases, you really have to design freely. The plot that the original poster is considering is also on a slope.

At first, the contractor will naturally make promises like "this won’t be a problem," but later on, the costs will increase.

Go to HOAI.de and input construction costs of 250,000€ (about $270,000), Fee Zone III, and the middle fee rate.

If you want to build to KFW 55 standard, you also need to involve an energy consultant. Without subsidies, that will cost around 5,000€ (about $5,400) more.

There are quite a few by now. Although not thousands of variations per provider, all the major ones offer a few suitable houses. Usually, some customization options are also available.

It doesn’t have to be that way. Our house is smaller, only 110 sqm (1,184 sq ft), and will cost 285,000 total. Of that, 68,000 is for the land. It’s doable. Karsten

There is quite a difference between these two quotes.

@Nordlys It makes a difference whether you’re planning a house for 2 people or 6.
You need not only more living and storage space but also a larger kitchen and a second bathroom – the OP is talking about two! Separate residential units...

And by rearranging a bit, you can turn a 4-bedroom house into a 5-bedroom one... that can also fit into about 165 sqm (1,776 sq ft) or so.

However, there are still some gaps regarding costs and so on.
It should also be mentioned that not all the cash you have lying around can or should be used as equity. The kitchen and purchase-related additional costs have been mentioned, but you should also deduct expenses for soft furnishings, furniture, lighting, and keep an emergency fund aside.

But: that’s the second step. First, you need to calculate how much of your income is actually left over or how much the house can afford to cost. You shouldn’t dismiss this too early, just as you shouldn’t assume building a house will be easy. At this stage, there’s no need to rush to a general contractor or buy a plot of land.

The first step is a sheet of paper with notes, numbers, and a table; the second step is a visit to a financial advisor.
You also need these numbers if you want to buy an existing property, so they’re essential.

Yvonne, I agree with you about determining your own budget. But don’t consult a financial advisor—go to your main bank instead. We’ve had experiences here in the forum with advisors who always say it’s possible; they even sell loans to severely disabled people on welfare benefits....Karsten

That works for me too... I’m not really familiar with those terms.
We didn’t need anything like that.
