Yes, demolition is unfortunately extremely expensive. But especially for the exterior or obvious parts, it’s a job that you can quite well do yourself. For us, the dismantling is at least mostly planned to be done by ourselves. For the disposal of normal construction rubble like bricks, walls, screed, we get family rates: they provide a 7cbm container for free, pickup €68 and disposal €38 per ton. I calculated this once with a 10cbm buffer and come to about €2,100. I haven’t researched window and radiator disposal yet. But I would prefer to have the breakthrough for the attic staircase done professionally. True, the door can be moved to the right and open to the right. Then the shower could be enlarged and the partition wall extended a bit so that maybe a narrow tall cabinet could be placed on the side of the washbasins. Possibly the bathtub and toilet could be swapped. That would have the advantage that you could look out the window from the tub. However, the disadvantage that you look at the toilet from the shower. We also don’t want a bidet, so the niche can be made smaller. I will work on this in the bathroom planner over the weekend and see how it looks. I will summarize the individual trades later, maybe it will then be easier to make a statement about accuracy :)

When bathing, you do everything else but look out the window. You rather close your eyes... what is the point of looking at the sky during bath time or the time of day?
More likely, when sitting on the toilet, it makes sense to glance into the distance.


What is disadvantageous about that? Many even use the toilet seat cover as a place to put their clothes...

True words! So basically six of one, half a dozen of the other. Then I’d rather leave the toilet at the back.

I’ve summarized the costs a bit again, maybe some can then make more of a statement:

Summary of the cost estimate

    [*]Demolition work: €16,615
    [*]Construction of knee wall and interior walls in the attic masonry and steel beam for wall breakthrough on ground floor: €33,365
    [*]Roof truss and roof (incl. 4 skylights): €45,602
    [*]Windows with electric shutters: €28,000
    [*]Gas, water, sanitary, bathrooms, underfloor heating, solar: €43,370
    [*]Screed work: €4,680
    [*]Electrical: €10,000
    [*]Front door system + canopy: €7,960
    [*]Interior doors (8x): €3,600
    [*]Insulation of basement ceiling: €2,430
    [*]Floors: €14,040
    [*]Interior plaster/painting work: €12,000
    [*]Exterior plaster/insulation: €26,100
    [*]Ventilation system: €8,770
    [*]Interior stairs: €6,000 (should be a concrete staircase)
    [*]Outdoor area: €23,000
    [*]Building application, architect, structural engineer, thermal protection: ~ €11,000


Edit: So windows alone are an item where you can easily spend much more, I’ve already learned that. We want triple-glazed plastic windows anthracite on both inside and outside with electric shutters. I already configured our windows and with one manufacturer I reached €28,000 including front door but excluding installation. At Drutex I was about half that amount excluding the front door and installation. In fact, from my point of view there’s absolutely no objection to Drutex especially since they have a warehouse + sales office nearby. Are there any experiences with them?

Oh come on. You can do without, but if I were building, that would be the last thing to be cut or compromised on my list.
