ᐅ 2 Bungalows on a 3,000 sqm Plot – Multigenerational Housing Project

Hello everyone,

First, a brief introduction. I’m Andy, 35 years old, married, and embarking on building a house for the first time. I’m an employee, my wife is self-employed, and together with my parents-in-law, we plan to develop a large plot of land. The plot is already purchased and fully paid for with equity. For the construction of the houses, we have a budget of around €1.2 million, of which about €600k come from the sale of existing properties (my parents-in-law’s single-family house and our condominium) and a financing commitment for up to €600k.

We are currently in the planning phase for a multi-generation project, but my main focus is our house (“House 1”). The parents-in-law have already completed the plans for their bungalow (basically a modified ground-floor layout of their current house). The design is mine, adapted by the general contractor, and is currently with the architect for further revisions. I would really appreciate any tips, feedback, and ideas you might have.

I’ll follow the provided questionnaire:

House design
Designed by: My design, implemented by the general contractor

What do you especially like? The atrium as a visual centerpiece and the related openness of the house

What do you dislike? Some wasted space, inconvenient furnishing of the walk-in closet due to 4 doors

Estimated cost according to architect/planner: €675k (approx. $720k) including paving, exposed concrete floor/wood flooring, painting, partial air conditioning, and additional upgrades. A horizontal roller shutter to close the entire atrium is also included (about €15k).

Personal price limit for the house including features: €750k (approx. $800k)

Preferred heating technology: Heat pump, photovoltaic system planned

If you had to give up something, on which details/extras
- could you compromise on: space in the parents’ area, 2 lift-and-slide doors in the atrium, lift-and-slide door in the living room
- could you not do without:

Why was the design made as it is?
After the attempt to build one large house including a granny flat on the front building plot was rejected, we are opting for two houses. To avoid further discussions about eaves height, we are building bungalows.
