We plan to install air conditioning in our new build in the near future. Currently, we are still at the shell construction phase and are considering what preparations should be made now to save costs later.
It’s a semi-detached house with a ground floor, first floor, and attic under a pitched roof, facing southwest. The garage is located to the left of the house, followed by a traffic-calmed street. I was thinking of a split system. Where would be the best place to install it? On the roof facing east? Or on the south side, on or in the shade of the garage?
The living room, the rooms on the first floor, and the attic should be cooled. It’s uncertain whether each room on the first floor needs its own unit (2 children’s bedrooms and a master bedroom including a dressing room), or if there is another way to handle this.
What should ideally be done now, and what can be added later without much trouble?
Looking forward to your advice.

You need two refrigerant lines, one condensate drain, and one power/control cable from the outdoor unit to every indoor unit. It’s best to plan and install these in advance. Retrofitting later is often not ideal, especially in terms of appearance.
Where is the best place to position the outdoor unit? Yes, shade is beneficial. Also, it’s preferable not to place it too high since the units are heavy and you might need a crane if it has to be installed on a roof. A garage roof is usually a good option.
Also, consider the length of the refrigerant lines. You should check the technical specifications of the outdoor unit to see the maximum allowed total length and height differences. Every meter adds significant cost.

Our outdoor unit is placed on the carport roof; a man carried it up there, so I thought it couldn't be that heavy.
We have one split system for the entire upper floor, one for the office, and one for the living/dining/kitchen area. According to the consultant, it's sufficient to cool down the upper floor in the evening, as houses nowadays are very well insulated.

We usually have 2 hot weeks a year. With shading, it never gets hotter than 23 to 24 degrees. I see air conditioning as a waste of money I can’t agree with that; we installed an air conditioning unit in our older house this year and have found it to be a huge comfort improvement, especially for sleeping conditions. Additionally, the system can also be used for heating down to around 7°C (45°F).
What needs to be prepared has already been well explained by mycraft. It’s also worth planning whether a single outdoor unit is sufficient or if it makes sense to install two. The refrigerant lines are not cheap and shouldn’t be too long, although I believe our system allows up to 15m (50 feet), depending on height differences.
Based on what you described, you might end up needing five indoor units, which pushes a single standard outdoor unit to its limits. Outdoor units also become increasingly expensive at higher capacities, so in the end, two units might be more practical. Regarding weight, we have a 4-split system; the outdoor unit weighs about 71 kg (157 lbs). Two people carried it onto the roof, and four of us lifted it through the roof window.
What people consider "too hot" varies a lot. For me, more than two weeks a year is definitely too hot, and the trend seems to be increasing.
My husband is from Queensland, where almost every house has air conditioning, and he wanted the same for our house here. It was basically his only real requirement for the house.
