Building:
Construction site (facing south)
![Baugrundstück Baugrundstück](../assets/images/Baugrundstuck.jpg)
The building ground was professionally filled, compressed and levelled by Otmar Hennchen.
![Baugrundstück - Untergrund Baugrundstück - Untergrund](../assets/images/Baugrundstuck_-_Untergrund.jpg)
Water, sewer, cable… connections placed, 20 cm Lava as anti-capillary layer, then fleece and 5 cm loose gravel on top.
![Baugrundstück - 240 mm Dämmung Baugrundstück - 240 mm Dämmung](../assets/images/Baugrundstuck_-_240_mm_Dammung.jpg)
The stay-in-place formwork (insulation) of the base plate is made of 24 cm XPS (hard Styrofoam).
![Baugrundstück - XPS - 2 Baugrundstück - XPS - 2](../assets/images/Baugrundstuck_-_XPS_-_2.jpg) ![Baugrundstück - XPS - 1 Baugrundstück - XPS - 1](../assets/images/Baugrundstuck_-_XPS_-_1.jpg)
We “hotwired“ the grooves for the perimeter-insulation and left a horizontal frost-protection.
![Baugrundstück - Bewährung Bodenplatte Baugrundstück - Bewährung Bodenplatte](../assets/images/Baugrundstuck_-_Bewahrung_Bodenplatte.jpg)
The steel mats (Q 434 A) look lighter than they are...
![Baugrundstück - Bewährung Baugrundstück - Bewährung](../assets/images/Baugrundstuck_-_Bewahrung.jpg)
Finished XPS-formwork (240 mm) and steel-reinforcement for the 25 cm concrete base plate…

While the concrete sets, we are drilling appr. 1 ton of flanges and pieces for the steel construction in our garage at home (upper pictures). Then we are sorting, marking and drilling 9 tons of steel beams at the production site of Thomas Laube (lower pictures) before the parts are welded. This works paperless out of the notebook (since the builder made the drawings…).
![Baugrundstück - Stahlteile Baugrundstück - Stahlteile](../assets/images/Baugrundstuck_-_Stahlteile.jpg)
Allways a good team! My wife aligning and me lifting the load (operating the crane).
![Baugrundstück - Bodenplatten mit Stahlteilen Baugrundstück - Bodenplatten mit Stahlteilen](../assets/images/Baugrundstuck_-_Bodenplatten_mit_Stahlteilen.jpg)
The base plates of the house and the garage are thermally separated. All zinc-plated steel parts (appr. 10 tons).
![Baugrundstück - Stahlbau Baugrundstück - Stahlbau](../assets/images/Baugrundstuck_-_Stahlbau.jpg)
The steel-construction was raised in 1 day. House and garage are separated (no thermal bridge).
![Baugrundstück - Fensterscheiben einsetzen Baugrundstück - Fensterscheiben einsetzen](../assets/images/Baugrundstuck_-_Fensterscheiben_einsetzen.jpg)
Installing the 147 kg 3-layer thermal glass into the windows supported by our window contractor Günther. Unconventional, like other details on this project, window-installation prior to roof and walls…
![Baugrundstück - Anlieferung der Sandwichelemente Baugrundstück - Anlieferung der Sandwichelemente](../assets/images/Baugrundstuck_-_Anlieferung_der_Sandwichelemente.jpg)
Delivery of the sandwich-elements. The crane I am operating is provided by Erwin Scherer. Do it yourself definitely pays off.
![Wände stellen - 1 Wände stellen - 1](../assets/images/Wande_stellen_-_1.jpg) ![Wände stellen - 2 Wände stellen - 2](../assets/images/Wande_stellen_-_2.jpg)
![Wände stellen - 3 Wände stellen - 3](../assets/images/Wande_stellen_-_3.jpg) ![Wände stellen - 4 Wände stellen - 4](../assets/images/Wande_stellen_-_4.jpg)
We were able to raise all of the wall-elements with 2-3 workers and a man-lift from Scherer.
![Baugrundstück - Wände Baugrundstück - Wände](../assets/images/Baugrundstuck_-_Wande.jpg)
Fastening (covered – bolts not visible) the sandwich-panels (Romakowski - wall M170 - U-value by EN 14509 = 0,147), outside insulation, finish and painting of the home are done in 1 step. At 17 cm wall-thickness the U-value meets passive-home-standard already!!!
![Wände stellen - 5 Wände stellen - 5](../assets/images/Wande_stellen_-_5.jpg)
Even the boss gives a hand at Laube steel construction!
![Baugrundstück - Wände anbauen Baugrundstück - Wände anbauen](../assets/images/Baugrundstuck_-_Wande_anbauen.jpg)
Cutting and mounting the smaller panels (17,1 kg/m²) works out alone.
![Baugrundstück - Dach Baugrundstück - Dach](../assets/images/Baugrundstuck_-_Dach.jpg)
The roof-panels (Romakowski - roof D 182 U-value by EN 14509 = 0,169). Additional windows and the main entrance will be cut out and mounted later...
![Baugrundstück - Haus von unten Baugrundstück - Haus von unten](../assets/images/Baugrundstuck_-_Haus_von_unten.jpg)
Only the sun trough the south facing windows is heating the construction site for now.
![Baugrundstück - Innenansicht Baugrundstück - Innenansicht](../assets/images/Baugrundstuck_-_Innenansicht.jpg)
The steel construction is completely inside the sandwich-shell and serves as additional insulation and installation space (power, water…).
![Baugrundstück - Haus am Ortsrand Baugrundstück - Haus am Ortsrand](../assets/images/Baugrundstuck_-_Haus_am_Ortsrand.jpg)
Quiet place heading south…
![Baugrundstück - Haus am Ortsrand - nah Baugrundstück - Haus am Ortsrand - nah](../assets/images/Baugrundstuck_-_Haus_am_Ortsrand_-_nah.jpg)
Lean-to roofs are becoming popular for homes in Germany and the advantage for solar use is evident. A positive energy footprint is guaranteed having 35 KW (peak) solar-power installed.
![Baugrundstück - Haus mit Terrasse Baugrundstück - Haus mit Terrasse](../assets/images/Baugrundstuck_-_Haus_mit_Terrasse.jpg)
Above the terrace, the solar panels are overhanging by 1.5 m to allow the low sun to heat through the windows during the winter and spend shade for the windows in summer.
![Baugrundstück - Fenstereinbau Baugrundstück - Fenstereinbau](../assets/images/Baugrundstuck_-_Fenstereinbau.jpg)
Installation of the remaining windows (these are facing west)...
![Baugrundstück - Eingangsbereich Baugrundstück - Eingangsbereich](../assets/images/Baugrundstuck_-_Eingangsbereich.jpg)
...main entrance (facing north-east).
![Innenausbau - Estrich Innenausbau - Estrich](../assets/images/Innenausbau_-_Estrich.jpg)
Alexander Witmann is applying the floating screed.
![Baugrundstück - Zisterne Baugrundstück - Zisterne](../assets/images/Baugrundstuck_-_Zisterne.jpg)
The cistern from Aquaroc is connected...
![Baugrundstück - Verbundpflaster Baugrundstück - Verbundpflaster](../assets/images/Baugrundstuck_-_Verbundpflaster.jpg)
Following the preparation and support of Thomas Eppert, we laid about 270 m² block pavement.
![Baugrundstück - Einfahrt Baugrundstück - Einfahrt](../assets/images/Baugrundstuck_-_Einfahrt.jpg)
The driveway got finished just prior to the winter. We will work inside now...
![Lüftungsanlage im Bau 1 Lüftungsanlage im Bau 1](../assets/images/Luftungsanlage_im_Bau_1.jpg)
We installed the ventilation system with heat recovery.
![Versorgungsschacht mit Lüftung und Kabelkanal Versorgungsschacht mit Lüftung und Kabelkanal](../assets/images/Versorgungsschacht_mit_Luftung_und_Kabelkanal.jpg)
Still visible, the auxiliary space for power, network and ventilation system will be accessible from the upper storage room.
![Trockenbau - 1 Trockenbau - 1](../assets/images/Trockenbau_-_1.jpg) ![Trockenbau - 2 Trockenbau - 2](../assets/images/Trockenbau_-_2.jpg)
![Trockenbau - 3 Trockenbau - 3](../assets/images/Trockenbau_-_3.jpg) ![Trockenbau - 4 Trockenbau - 4](../assets/images/Trockenbau_-_4.jpg)
Drywall installation – mounting the first UW and CW – channels. Then continue until you miss the forest for the trees.
![Kabel verlegen Kabel verlegen](../assets/images/Kabel_verlegen.jpg)
Here we are, installing the wiring & network before the sound absorption material (rock wool) can be installed.
![Innenausbau - Thomas - Verteilerkasten Innenausbau - Thomas - Verteilerkasten](../assets/images/Innenausbau_-_Thomas_-_Verteilerkasten.jpg) ![Innenausbau - Verteilerkasten 2 Innenausbau - Verteilerkasten 2](../assets/images/Innenausbau_-_Verteilerkasten_2.jpg)
Our friend Thomas Pohl is helping with the electricity. This is how it looks like if you would like to connect every switch and each socked in every room independently and not all of the 2000 m cable arrived her yet.
![Innenausbau - Isolierung - Klaudia Innenausbau - Isolierung - Klaudia](../assets/images/Innenausbau_-_Isolierung_-_Klaudia.jpg) ![Innenausbau - Isolierung - Hanne Innenausbau - Isolierung - Hanne](../assets/images/Innenausbau_-_Isolierung_-_Hanne.jpg)
Teamwork applying the rock-wool to all outer and inner walls (sound absorption).
![Innenausbau - innere Dampfsperre Innenausbau - innere Dampfsperre](../assets/images/Innenausbau_-_innere_Dampfsperre.jpg)
We are applying a foil (inner vapor barrier) between the two layers of sheetrock.
![Innenausbau - Innenwände Innenausbau - Innenwände](../assets/images/Innenausbau_-_Innenwande.jpg)
Following the second layer of sheetrock on the outer walls we are completing the inner walls.
![Innenausbau - Schleifen... Innenausbau - Schleifen...](../assets/images/Innenausbau_-_Schleifen....jpg)
Despite the vacuum cleaner being connected to the machine, this is a very dusty job.
![Innenausbau - Entspannung - Klaudia Innenausbau - Entspannung - Klaudia](../assets/images/Innenausbau_-_Entspannung_-_Klaudia.jpg) ![Innenausbau - Entspannung - Wolfgang Innenausbau - Entspannung - Wolfgang](../assets/images/Innenausbau_-_Entspannung_-_Wolfgang.jpg)
Performing exhausting jobs we need a brake – everyone in her/his way...
![Innenausbau - Streichen - Klaudia Innenausbau - Streichen - Klaudia](../assets/images/Innenausbau_-_Streichen_-_Klaudia.jpg)
Painting is almost a clean job (following the dust of grinding). Klaudia is preparing the edges…
![Innenausbau - Streichen... Innenausbau - Streichen...](../assets/images/Innenausbau_-_Streichen....jpg)
... and Wolfgang paints the areas.
This is how our “energy-plus home made of steel” looks like:
