ᐅ 220 m² for a semi-detached house? Plenty of space

So, the plan already sketches one half of a semi-detached house measuring 7 x 11 m (23 x 36 ft). That results in a footprint of 77 m² (829 ft²) for the house. There should be at least 3 m (10 ft) of setback from the street and on one side. Parking spaces are still missing, but maybe these are meant to be on the opposite street side?!

I only quickly measured this on the computer, so I cannot guarantee accuracy: According to your plan, the garden would be about 11 m (36 ft) wide and 8 m (26 ft) long (measured from the outer edge of the house to the property boundary), giving around 88 m² (947 ft²). This would be the main area for a terrace, flower or vegetable beds, and possibly children’s play equipment. In addition, there are two narrow strips along the other two sides of the house, although one of these will probably serve as the entrance area, location for an air-to-water heat pump outdoor unit(?), and space for trash bins.

Still, I would recommend trying to visit similar plots (with existing buildings!) so you can get a real sense of the space. For example, my in-laws have been living for 30 years (first as three people, now two) on a similarly sized plot with about this garden area (without the narrow strip, since it’s a mid-terrace house) and they absolutely don’t miss anything. For me personally, it would be too small.

What is the yellow area? Existing building to be demolished?
Do you have additional parking spaces for cars?
We have a homeowner here who needs to provide 2 parking spaces on a very small plot (10 meters wide (33 feet), end of a terrace, 3-house row). Maybe you can find the thread by searching those keywords, or someone here might remember the name.
By the way, their issue with terraced houses is very interesting: all houses are built separately with different main contractors, which would also affect you. Or are you building with a single developer?

If everything else fits, I would buy it. There is no reason not to.
However, we don’t know your family. If you want to accommodate 6 people with their own bedrooms, it might get tight, and there are no options for expansion.
We had a detached house ourselves on a 25 x 9.5 m (82 x 31 feet) plot. The front garden took up 5 meters (16 feet) of the back area.
Many others with similar sizes gave up lawn space, made a bigger terrace, and otherwise kept only shrubs.

So: you can’t make big changes in the garden, but for 2-3 people it is quite manageable, allowing you to enjoy some vacation time at home.

Practically nothing can be understood from this colorful drawing without a legend. Plot ratio and floor area ratio, roof pitch, heights – all are missing. So, we can only guess (which is not enough): the red areas might represent the new building envelopes, the yellow ones those of the existing structures – but it just looks colorful, not clear.

As a "basis for evaluation," only the plot size remains: 220 m² (2368 ft²) – assuming a plot ratio of 0.4 and a floor area ratio of 0.8 – which could ultimately result in about 140 m² (1507 ft²) of living space per semi-detached townhouse unit. Please provide proper basic information; otherwise, it’s just reading tea leaves.

The only basis to assess is the plot size: 220 sqm (approximately 0.4 plot ratio / 0.8 floor area ratio) could eventually result in about 140 sqm (1,507 sq ft) of living space per semi-detached townhouse half. Get some solid fundamentals in place, otherwise it’s just reading tea leaves.

The plan is for a two-story semi-detached house with a 30-degree pitched gable roof.
The building footprint should be 7 by 11 meters (23 by 36 feet).
Yellow indicates the existing building, which will soon be demolished; a positive preliminary building permit / planning permission has been granted.

We have a client here who has to provide 2 parking spaces on a very small plot (10 meters width (33 feet), end-of-terrace house, row of 3 houses). Maybe you can find the thread using these keywords or someone here remembers the name.
By the way, his issue with the terraced house is also very interesting, since all units are built separately by different general contractors, which would also affect you. Or are you building with a single developer?

But many others with similar sizes gave up on a lawn, made a bigger terrace, and otherwise only planted shrubs.

So: you can’t make big moves in the garden, but for 2-3 people it’s manageable enough to also take a vacation at home.

The existing building will be demolished soon.
There are enough public parking spaces available nearby.
Currently, my partner and I plan to move in there.

I am not tied to any developer, so to build cost-efficiently, it would probably make sense to choose the same developer with the other party.

And that will exactly be the problem if the other partner has completely different building preferences: basement/no basement, brick/ plaster finish, house style, roof pitch, etc.
