Hello dear home builders!
Due to the continuously rising prices of land and real estate, we have decided to renovate and extend the existing semi-detached house of our parents and grandparents.
We have access to the first floor of the right half of the semi-detached house, as well as the entire attic spanning both halves (a total of 157 sqm (1690 sq ft) plus a 55 sqm (592 sq ft) roof terrace). In addition, a garage with two parking spaces and 20 sqm (215 sq ft) of storage will be created. The heating for all three households is located in the basement, so in our area only a hot water tank is needed.
The external footprint and size of our project are already fixed. However, the internal layout, as well as the windows and doors, can still be modified.
The entrance area will be built differently from what is shown in the plan: a partition wall will be added at the middle of the existing staircase leading down to the ground floor, and custom carpentry will create storage space both for us and for the grandparents’ unit since we do not want or need a direct passage to their apartment (removing the staircase would be too much work). The main door is, by the way, located on the landing of the existing staircase (half way up).
Additionally, in the kitchen and pantry, two chimneys from the lower floors have to be taken into account. These cannot be removed and must be integrated into the design.
Development Plan / Restrictions
Plot size: not relevant in our case
Number of parking spaces: 6 covered parking spaces
Number of floors: 1st floor + attic
Roof type: gable roof
Orientation: terrace facing southwest
Homeowners’ Requirements
Basement, floors: 1st floor, attic, heating in basement, double garage with storage
Number and age of occupants: 2 adults, 2 (planned) children
Room requirements: separate kitchen and dining area, living room, bathroom, toilet, 2 children’s rooms, master bedroom, office, utility room
Office: family use or home office? Home office
Guests per year: not relevant
Open or closed layout: closed
Open kitchen, kitchen island: if possible
Number of dining seats: 8 (frequent guests)
Fireplace: if possible
Balcony, roof terrace: 55 sqm (592 sq ft)
Additional wishes/particulars/daily routine, also reasons why certain things should or should not be: An open living/dining area is not desired because we often have guests (women’s or men’s groups), and one of us prefers to relax quietly in the living room.
House Design
Planned by: architect
Preferred heating technology: pellets (existing building has radiators, no underfloor heating)
If You Had to Give Up on Anything, which features/extensions
- could you live without: walk-in closet
- couldn’t you live without: large roof terrace, separated living room, separate toilet near the kitchen, pantry
What do you think of the floor plan? Unfortunately, when renovating, you are never as free in planning as with a new build. The entrance area especially does not fully satisfy us (too narrow, and it requires going up two floors to reach the living area). However, since we are building it ourselves and cannot afford more due to land prices over €1000 per sqm (over $100 per sq ft), we will have to bite the bullet on this.
Thanks in advance!
Best regards

How are the floor area ratio and parking requirements specified in the development plan? Also, the heating system is an interesting point. What is planned there? The architect should already know that. As far as I have read, there are 6 covered parking spaces.
Regarding the heating: the original poster says "preferred heating technology: pellets (the existing building has no underfloor heating, only radiators)."
Additionally, a stove is planned in the living room, but unfortunately on the wrong wall.
I am also missing many essential details to fully understand the situation. From the drawings, I interpret that an entrance platform is to be added to the first floor of one of the two semi-detached houses, providing the third residential unit (a maisonette penthouse) with its own "front door" there. Clarifying information about ownership would be very helpful here. The newly converted third unit actually spans both semi-detached houses (hopefully this is a condominium/shared ownership property, and not an attic covering two separate properties?). This will certainly not be a simple matter for all parties involved in the planning, and I already imagine the financing to be complicated in any scenario. Additionally, the other two parties are referred to as "parents" and "grandparents" (which means, for part of the couple, the prefix "in-law" applies). I hope (especially regarding potential inheritance issues that are relevant for financial security) that the (in-law) grandparents do not have any heirs besides the (in-law) parents and/or the parties responsible for the renovation and conversion. Otherwise, the "building plot" in the form of the "split-level foundation slab with an access stairway to the front door" is still the relatively manageable part of this construction chaos.
Against this background, the question of whether the 25cm (10 inch) exterior wall is made of 1980s "aerated concrete" (which would require minor insulation upgrades) or 1950s solid brick (ouch, that’s more problematic) becomes almost insignificant.
The lady of my heart complained about my nested sentences again yesterday, but no buddy is perfect ;-)
