Then I would also like to introduce our building project here and keep you updated.

First, a brief introduction about us. He (42.5 years; controller in healthcare), she (38.5 years; full-time teacher), child (8.75 years; fully dependent). Our household net income is currently about €6,400 (approximately $6,800) plus performance bonuses, 13th-month salary, overtime, etc. We own a 1,462 sqm (15,735 sq ft) plot of land in Fichtenwalde. The remaining debt on the land is €37,000 (about $39,000). According to official land value guidelines, the land is valued at €146,200 (about $156,000) (€100 / sqm). The market price is around €400,000 to €600,000 (recent sale prices). We submitted the building permit application including the land conversion at the end of December. We expect approval by mid to late July.

The construction company is KB Brandis from Jüterbog. External site supervision will be handled by Bauherrenhilfe with 13 appointments.

Now about the house. It will be a 144 sqm (1,550 sq ft) bungalow plus a 12 sqm (130 sq ft) covered terrace with the following additions:
- Ceiling height 3.00 m (9.8 ft)
- Electric roller shutters (including smart home integration)
- Double-sided laminated windows (wood-colored; RC3 security rating)
- Brine-to-water heat pump with ground collectors due to water protection area (Bosch Compress 7800i LW)
- Hydraulic balancing of the underfloor heating
- Controlled residential ventilation with heat recovery (Bosch)
- Motion detectors from a security company
- 13 kWp photovoltaic system, including battery preparation
- 10 m³ (2,650 gal) cistern for rainwater use
- Doorbell with video function
- Wallbox preparation for electric vehicle charging
- Exterior lighting

Floor plan attached.

We have not yet finalized financing (although discussions have taken place). So far, we have invested up to €30,000 (approximately $32,000) from our own savings during the planning phase. This is almost all of our equity. However, we continue to save about €2,750 (approximately $2,920) per month. The monthly mortgage payment is expected to be around €1,650 (about $1,750) plus additional costs of approximately €200-250 (about $210-265) (taking into account the photovoltaic system). This means when we move into the house, we will still have savings of at least €1,500 (about $1,590) per month.

The construction contract will be signed within the next few weeks. The prices (recently discussed with the company) correspond to the offer and commitment as of September 2020.

The price per square meter of the house (according to the latest offer and full specification) will be €2,700 (about $2,870). This includes everything, such as painting, flooring, etc. The overall costs are structured as follows:
House: €378,000 (about $402,000)
Land conversion including reclassification: €25,000 (about $26,600)
Additional building costs: €40,000 (about $42,500)
Outdoor facilities: €25,000 (about $26,600)
Total financing volume: €468,000 (about $498,000)

I haven’t read everything in detail, but have you already furnished the living room? It looks quite tight, and the table seems to be placed almost in the hallway and awkwardly in front of the window.

Thanks for the suggestion. We have already furnished the room. Since there are three of us, the table will be about 1.60m - 1.80m (5.25 - 5.9 feet) long and the sofa approximately 2.4m x 1.80m (7.9 x 5.9 feet). We have placed all our furniture that we plan to bring with us. Everything fits very well. Of course, it won’t be a huge amount of space, but that’s what we wanted; otherwise, we would have built much bigger.

Our approach is: "We build for ourselves, not for others" 🙂

Now, to be honest, I’m a bit surprised that it doesn’t “fit very well” after all. 😉 With my sketch, I had already tried to give you a clear picture of this. Regarding your question: yes, I would remove the terrace and incorporate that space into the living room. AND I would definitely add more window area on the left side of the living room. Do yourself a favor and draw your furniture into the now larger living room; then see where you face a wall and could benefit from an additional window. Windows near the dining table are always a great feature.

The furniture fit, but we did not expect the fireplace to be 1.64 m (5 ft 4 in) wide :-)

Whether we paint the terrace depends on the energy efficiency consultant. If we don’t receive a KFW 55 subsidy due to the change, then it won’t happen.

More windows on the left side would only cause even more heat gain, since the sun moves from the north (5 p.m.) to the south (11 a.m.) there.

We will see what the energy efficiency consultant advises.

A brief explanation of why our furniture fits without any problems.

a) We are choosing a table that is about 1.60 meters by 0.80 meters (5 feet 3 inches by 2 feet 7 inches), which is extendable, since in 95% of cases, three of us will be eating.

b) The same applies to the corner sofa. It is a maximum of 2.50 meters (8 feet 2 inches) in length, or rather less.

We were aware that this setup wouldn’t make for a large living room, but it would be sufficient for us. We will take a closer look at it again today and are waiting for the consultant’s response.

Haha, in 95% of cases, we only eat as a couple and have a 2.20m by 1.00m (7.2 ft by 3.3 ft) table. But we also enjoy hosting bigger meals sometimes and have the space for a large table. :p

We also have very large south-facing windows in the living room, which are shaded with external blinds on hot days. This keeps it bright but really cool inside. On the other hand, in spring, autumn, and winter, we appreciate the warming sunlight. Just something to consider. But let’s see what your energy consultant suggests.

I would rather think that without the terrace, you would be in a better energy position, since the window would no longer be shaded by the roof, and that is (partly) the south-facing side, right?

I don’t believe you will need a completely new building permit / planning permission, but you definitely will need a revised plan, as you’re not just moving one window, and this affects the building volume and so on.

The question was whether any changes are still possible. The application is for about 140 m² (1507 ft²). Now it will be 150 m² (1615 ft²) with the change.
