ᐅ Our lifelong project: A single-family home with 8,600 square feet of living space

Good morning ladies and gentlemen,

I have found the form that everyone usually fills out in advance to provide more input. We are still trying to find a suitable plot of land. Most of the properties currently listed online in Hesse have either a too low floor area ratio or site coverage ratio, or they are unsuitable due to their location or neighborhood.

In general, we are not fixed on Hesse and have decided to remain flexible, as long as the location is not in the eastern part of the country (too far away for us), since this building project is only intended as a second home, to be used as a weekend house.

We see this house as our last major construction project before retirement. We are both very skilled at DIY work, so tasks like electrical installation planning, bathroom construction, and even building a sauna and steam bath have already been completed entirely by ourselves. We also finished the last interior work completely on our own, as well as the garden including the terrace and pond, independently built. As you can see, there is a high level of own initiative and expertise, which we believe enables us to successfully undertake such a project. Additionally, we aim to keep labor costs low by "optimizing" taxes and contributions.

General information about you:
Who are you? Father, mother, 2 teenagers.
How old are you? Parents are in their late 40s, children around 18 years old.
Are more children planned? No.
Are you employed, self-employed, retired, homemaker, etc.? Father is self-employed (lawyer with his own practice), mother does not work.

Income and assets:
What income do you have (gross/net)? Net: at least €30,000 per month as private withdrawal
How much equity do you want to invest in the house project? Preferably a low equity share to make the most of the current available funds (our consideration)

Housing costs:
No rent, own single-family house

General information about the property:
How large is the plot? We are trying to secure a plot from 1500 sqm (approximately 16,150 sq ft) upwards, preferably larger. Our motto is: the bigger, the better. Please feel free to post ideas on where to find such plots in Hesse – private tips via PM will of course be rewarded. We would need a building envelope with dimensions of about 34 x 25-30 meters (112 x 82-98 ft).

New build, existing building (year built), house type? Garage? New build with underground garage (a major wish to accommodate my husband’s small car collection)
How big is the house? (living area / usable area): approximately 800 sqm (8,600 sq ft) plus basement (part underground garage, partly fitness room, etc.)

Construction or purchase costs:
Plot costs: We are budgeting up to half a million (Euros); please correct us if this seems unrealistic. The last time we built was in ’08-’09, and at that time such a budget still worked well for the land.
Development costs: Unknown
Building or purchase costs (including architect, structural engineer): estimated €1,000,000 - €1,500,000
Additional construction-related costs (e.g., utility connections, soil surveyor, temporary power, etc.): Unknown
Outdoor facilities/terrace, paths, garden design, fences, etc.: Outdoor pool desired
Total costs: €1.5 - 2 million

Cost breakdown:
Total costs: €1,500,000
Deductible equity: e.g., €150,000
Financing amount: €1,350,000

Attached you will find some pictures that inspired us stylistically and that represent what the final product should look like. Of course, we know this project is quite demanding in terms of effort and execution, but we are confident that with our ideas and contacts within the industry, we should be able to realize it.

We very much look forward to your input and hope to receive ideas on implementation, opinions on the budget, and suggestions for possible locations of the plot.

Best regards,
S.
