Hello everyone,

I/we plan to start building in about 3-4 years, and I am already researching diligently. Better too early than too late. 🙂
I’m not sure if there is already a thread like this, but I couldn’t find anything with my search terms. If there is, please forgive me. Also, is this topic even in the right forum?

We already have a rough plan in mind for our future dream house. The design and layout are inspired by the "Modo Home MH5." May I post a floor plan of this house here for a rough overview?

The suitable plot of land is around 4000 sqm (43055 sq ft) and mostly flat (no typo) — the connection request is already in progress.
Brief keywords:
- Bungalow with a flat shed roof facing east → large windows facing south/west
- Double garage
- Covered large terrace
- Approximately 220 sqm (2368 sq ft) of living space
- No basement
- Large photovoltaic system + battery (our next car will very likely be a BEV. Smart charging with photovoltaic power)
- Controlled mechanical ventilation with heat recovery
- Possibly KNX control system + alarm
- No roof windows or roof structures (chimneys, satellite dishes, etc.)
- Budget for the house is about €400,000-500,000

Since we are still at the beginning of the planning phase and I am also researching materials (solid construction, timber frame, etc.), efficiency classes, heating methods (air/water or ground/water heat pump), I wanted to ask what you would have done differently right from the start or what should be taken care of early on.

I would find fundamental advice like “definitely don’t build solid because…” as helpful as small tips like “make sure to have a power outlet in area XY.”
My plan is to build the house as “finished” as possible, to avoid things later like high ongoing costs, early remodeling, or avoidable multiple power strips and cables.

So far, these are the things I have considered:
- Completely single-story and barrier-free (including showers, etc.)
- Wider doors (in case a wheelchair is needed someday)
- Wastewater heat recovery in the shower
- Centralized technology, e.g., ceiling speakers with a central amplifier, and devices like an AV receiver and computer/server will all be placed in the technology room
- Many LAN/fiber optic connections in rooms and the ceiling (for access points)
- Many power outlets with integrated USB-C ports
- All cables that can become outdated are installed in conduit pipes to allow easy replacement

As you can see, this list is still very tech-focused since we both work in IT. 🙂
I am currently reading up and gathering information in other areas as well.

This thread is also meant to highlight things other “home builders” might not have thought of yet.
If you have any questions, please feel free to ask.

Best regards

It's always a bit difficult when there isn't a specific question..
But what immediately stands out to me: if you mean what you get when you google MH5, you can quickly forget about all those wishes with a budget of 400,000–500,000 euros (approximately 430,000–540,000 USD).
If there's no possibility for a higher budget, you should already prepare to consider a different house.

Forget about inspiration if you are looking at a top-class 344 m² (3700 sq ft) house as a model that doesn’t quite meet your space requirements and might be 5 to 7 times more expensive.

Even for your house with "only" 220 m² (2368 sq ft) of living space (plus additional usable space, garages, terraces, etc.) and expensive fittings/design, you will crash your budget.

So here is just one piece of advice: reconsider your expectations, because they don’t match your budget.

Regarding the budget:
This could be adjusted upwards slightly.
I was referring to the house plus garage themselves. The land is already owned, and utilities, landscaping, and other exterior work will be calculated separately. Of course, there is no pool or fancy features like the fire pit on the terrace or wood cladding as in the show home. This will be designed more simply. This house mainly focuses on the general floor plan and layout. Features like KNX or similar smart home systems are optional.

You hopefully realize where the benchmark for cisterns on 4000 sqm plots lies in this forum *ROTFL*

If you avoid using the “rest” of the 4000 sqm completely for parkland and driveway, and instead resell part of it as building land, the budget should be easier to increase. Then you can also save yourself the significant contortion of scaling down a 344 sqm (about 3,700 sq ft) luxury mansion to a 220 sqm (about 2,370 sq ft) weekend house.

This thread should also point out things to other “home builders” that might have been overlooked so far.

This forum already does that as a whole. Maybe you should try reading through it here over several weeks in a traditional way instead of just quickly searching.

The estimate didn’t cover more than that. Just calculate roughly with €2,500 per square meter (approximately $260 per square foot) of living space, which totals €550,000. Add additional construction-related costs of €50,000, a double garage for €30,000, and some landscaping including the terrace for €50,000. This brings you to about €700,000 including the kitchen. This doesn’t yet include the installation of the grounds, the photovoltaic system, or any larger extras.
