ᐅ Affordable Building Without Compromising Quality, Architect-Designed Home

Hello everyone!

I have been quietly following this forum for some time, and our house-building project (single-family home) will probably start in Q1/Q2.
I am wondering how to build a house in 2024 cost-effectively without compromising quality.

We have a budget of about 500,000-600,000 euros for the entire construction (excluding the land).
That is a lot of money, but not unlimited – I want to get the best out of it.

A brief overview of our project:
~120m2 (two floors), steep slope, no basement (not possible), 2 adults (maybe one child max in the future), undeveloped plot.

I assume that land development, slope work, and foundation slab will cost around 100,000 euros.
That leaves around 400,000 euros for a move-in ready house.

We have already looked at prefab house providers, but none of their offers matched what we wanted – customizing prefab houses is about as expensive as working directly with an architect.

The plan is to have the house built "ready for finishing" (shell and core) and carry out most of the interior work ourselves (walls, floors, tiles, bathrooms—only the tiling!—and outdoor terraces). We have sufficient craftsmanship skills for this!

Where is the best place to save costs?
What features are often installed without real benefit? (e.g., laundry chute, central vacuum system, automatic blinds, etc.)
Where should you definitely not save?
Should an independent expert inspect the work? Or is that a waste of money for a general contractor/architect-led build?
Should the construction contract be reviewed by a lawyer?

My current thoughts are:

* Simple building shape (rectangle), straightforward pitched roof construction
* No unnecessary home technology (ventilation system, smart home, etc.)
* Minimize large window areas
* Only a carport, no double garage
* The building method (timber frame, solid wood construction like Holz100, masonry) is still open – I prefer timber frame/solid wood.
* Good planning once is cheaper than planning two or three times
* Double checking is cheaper than fixing poorly done work afterwards
* A wood stove is nice, but a fireplace is also expensive.

Where else can you save? What unnecessarily drives construction costs up?

Our idea is:
If we skip things like a double garage, we have more budget for high-quality interior finishes.
We prefer to invest in interior finishing rather than, for example, a laundry chute, central vacuum system, automatic blinds, and so on.

I understand that features like a laundry chute can be subjective when it comes to being "unnecessary" or not.
The goal is to figure out what is essential for a house build, where one should definitely not save, and which elements can be omitted.

There are also significant price ranges for stairs, windows, doors, facades, and roof coverings.
Does it have to be an expensive branded roof? Will a cheaper option suffice?

With this "pre-planning," I also want to minimize the cost of architectural planning. If we come to the architect with a realistic, well-thought-out plan, it probably saves a few thousand euros... Also, an independent building surveyor can save money by detecting issues early on – once the progress payment is made, it is hard to get the money back.

Thanks in advance for your tips and opinions.

Is the plot accessed from the top or from the bottom?

From the southeast, so from the bottom.

More pictures....
The marker should be the cabin, the rest I believe are trees... unfortunately, I can’t remove them.

I think your €100,000 for the landscaping would make a better down payment here...

How much do you think something like that would cost?

Here’s another profile of about the "western edge of the cabin."

Then you will have to set the house lower than where the cabin is located. The driveway and stairs will be costly, become steep, and need to be cleared and salted during winter. There are nicer things than coming home after a day's work and not being able to get into the garage because the driveway resembles a ski slope.

Additionally, the utility connections. Even in Austria, every meter of pipe or cable that needs to be laid will cost money.

For $100k, you won’t get the entire plot terraced and retaining walls installed.

My current idea is to have only the wall directly against the slope in the ground floor made of concrete, and to build the rest from timber. (No idea if that is structurally possible.)

You’re forgetting that it’s not just the back facing the slope, but roughly half of the sides will also be embedded into the slope. The slope will continue to run along the left and right sides of the house as well.
Structurally, many things are possible. But combining different types of exterior walls in the same story is bad construction practice.

I’m starting to wonder if I even want to live on a plot like this 😳
