You, those are not good conditions if the person responsible in the municipality (and also the architect) tells you exactly the opposite. And the document that is the development plan requires three parking spaces (one for commercial use). I simply cannot disregard that.
If I have a tiny terrace, a mini house, no space for trash bins, no garden shed, and not even a double garage for the lady and me after €450,000, I might as well continue renting. There I have two parking spaces, space for a trash bin, 50 sqm garden with room for a grill, lounge chair, and parasol, and 90 sqm living space for €450 per month. This has nothing to do with being flexible or not, but with cost/benefit. ;-)
