House with integrated apartment, IBG floor plan example explanation?

Hello,

we (I mean my wife and our child) are planning to move into a house together with her parents (my parents-in-law).

I have looked at various options for living together. What is important to me is that there are two separate apartments. Living together yes, but please everyone with privacy. :D

What is currently developing in my mind is the option of a house with a granny flat as the most cost-effective solution. The granny flat should be somewhat smaller than the main apartment in the house. But it would probably be plenty for the parents since they are currently living on 25 sqm :(.

I have a catalog from IBG Haus here with a sample floor plan but I really can’t imagine much from it, unfortunately the description is very sparse.

Can someone briefly explain whether such a house with a granny flat has two separate lockable apartments (only 1 front door, because that saves connection costs).

Are there other similar options?

Best regards

Hello Cmajere,

since I have been involved in house sales for many years, I have accumulated some floor plan examples for two-family houses (house with granny flat = ELGW). Before you dive into a floor plan collection here, you should check how large your plot of land is, because these houses can sometimes have quite large exterior dimensions and may not always fit.
By the way, a “real” house with granny flat involves a bit more than just two doors... Think about the building services supply. It does not necessarily have to be two heating systems, but the floor plan should provide a central room accessible to both, e.g. for the heating system. This is then installed so that the second apartment gets a heat meter to bill correctly. Your electrical meter cabinet must also be large enough to accommodate the additional meter space for the granny flat – this costs a bit more than a standard meter cabinet. Sound insulation should also be considered during construction. At the moment it is your parents-in-law, but such a house is planned for many decades. It might happen that strangers move into the house, or it is turned into a holiday apartment. Then everything should be correct, because at the latest when real tenants are living in the house, it must comply with the planning and execution requirements of a two-family house.

One very important tip! Please do not only focus on beautiful catalogs for your building project..., look at the contract carefully! Do not make any advance payments, pay only according to construction progress, get a completion guarantee (from an independent bank or insurance, or retain payment until completion) and a warranty guarantee (bond). Only if all this is right, the build description shows no service gaps (which by the way does not mean the builder has to offer every imaginable service, but rather means the scope of services is exactly described and you are told what else to expect), the price is okay (not too cheap, not too expensive) and you simply have a good feeling, then award the construction contract and look forward to a wonderful time in your new home!
