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

It’s unfortunate that you didn’t include the ground floor, as that confuses many people. Especially if the unpleasant entrance area is located there now, if I understood correctly. That part is often copied quickly, and then changes are marked in by hand.
Overall, I think the plan is good except for the master bathroom. At first glance, not everything is entirely clear. Are there any sloped ceilings in the attic? If yes, how high is the knee wall and where is the 2-meter (6.6 feet) height limit? Is the roof terrace being "added on"? If so, what does the structural engineer say about it? I’m also interested in the kitchen’s wastewater disposal. Unfortunately, the kitchen is particularly hard to interpret. The best approach would be to redraw the cabinets in color. Are the windows on the upper exterior wall already existing?

After a long time, I have understood the design. Without knowledge of the basements, it is difficult to comment. In my opinion, the architect has implemented what you want. The entrance area can still be improved somewhat. Is the main staircase a concrete staircase? If so, I would install a partition wall two steps lower and add a wardrobe there, since a downward staircase is not desired.
Basically, mirror the living room to move the stove/fireplace to the other side.
I would not block up the window on the first floor.

At first glance, I like the plan except for the master bathroom. Not everything is immediately clear. Are there roof slopes in the attic? If so, what is the knee wall height and where is the 2-meter (6.5-foot) height limit? Is the roof terrace going to be attached directly to the structure? If yes, what does the structural engineer say about it? I’m also curious about the kitchen’s drainage. Unfortunately, the kitchen is especially hard to make out. It would be best if you could mark the cabinets in color. Are the windows in the exterior wall at the top of the plan already existing? I assume the existing building’s roof is unfinished. They’re adding a concrete ceiling above the first floor with the roof terrace on top and then an attic with a flat roof.
Although the 25 cm (10 inches) exterior walls rather suggest a timber frame construction.
Something like this could definitely be clarified by elevation and section drawings.
This won’t be cheap.
I’d be interested in the architect’s cost estimate. I’d guess around 450,000.
