ᐅ Combination of Solid Construction vs. Timber Frame Construction

Hello collective intelligence,
Our building plot was flooded to a depth of about 20cm (8 inches) during the last flood, which is why our architect suggested raising the house 1m (3.3 feet) above ground level.
Since we also want the technical equipment to be protected from flooding, he proposed placing the utility room above the garage, as locating it inside the house would unnecessarily reduce living space. In contrast to the solid masonry house (42.5 Perlite), the utility room would be connected to the house using timber frame construction and insulated with 20cm (8 inches) of insulation to achieve the same thermal performance. The exterior will be finished with a standard render.
The advantage here is that since the garages are slightly lower than the house, the utility room would have direct access to the ceiling of the ground floor and the ceiling of the upper floor. However, I am not sure how wise it is to combine these two construction methods. On the one hand, there are concerns about thermal bridges and air leakage in the building envelope over the long term, and on the other hand, sound insulation.
He would also like to use a combined unit with both ventilation and heat pump in one system, but I have some concerns about a single point of failure, and even more so since the heat pump compressor would be located at the height of the bedrooms, which worries me.
I would prefer a separate heat pump placed 10-12m (33-39 feet) away at the edge of the property.
What do you think of this idea?
The pictures from a 3-year-old are meant to help visualize the idea

Gustav57896 Feb 2025 15:11The term “builder” was the wrong word; I meant the general contractor. I am the client. All this work is turning my brain to mush.
We found an architect to advise us, but as we realized later, he seems to have his own ideas that he wants to push and tries to convince the client to accept. Since we are already deep into the planning with him, I don’t want to waste the money and write it off, but rather get him to ultimately do what we want.
How can I tell what counts as a custom solution and what doesn’t?
I have an existing plot of land where I would like to build an additional house with a double garage. The soil report shows some difficulties that will add extra costs, but otherwise, we want to keep everything as standard as possible.
Can I upload the site plan along with our own sketch in this thread (or a new one) and ask for input?

We hired an architect to advise us, but as we realized over time, he seems to have his own ideas that he wants to push through and tries to convince the client of them. Since we are already involved in the planning with him, I don’t want to just waste the money and write it off, but try to get him to do what we actually want in the end. I don’t know your contract with the architect, but I wouldn’t expect improvement from a poor listener. It’s best to part ways with an unsuitable architect during the initial, less costly design phases. Strange characters often are what @Gerddieter warns about, especially regarding sticking to the budget.

I have an existing plot of land on which I would like to build an additional house with a double garage. The soil report indicates some difficulties that will cause extra costs, but apart from that, it should be as standard as possible.
Can I upload the site plan along with our own sketch in this thread (or a new one) and hope for some feedback? You can recognize a custom solution by the fact that it takes unusual approaches that are not required by any of the framework conditions. Since we are already on the second page and the completed questionnaire https://www.hausbau-forum.de/threads/grundriss-planung-unbedingt-vor-beitrag-erstellung-lesen.11714/ is ideally included in the opening post, it’s better to start a new thread for this and link it here.
