Cost opinion on planned single-family house

I do have to wonder sometimes about the prices being asked here. It is certainly possible to handle the interior finishing with €14,000 by doing it yourself. Of course, I can’t then choose the designer toilet bowl, the 2 x 2 m level-access shower in Corian, and the handmade tile at €120/m². A normal, nice equipment that matches each other is doable, at least for me. And building materials like grout, sealing in the shower cabin, and Schluter rails really don’t cost the earth.

I think one shouldn’t let themselves be driven crazy. Sure, the rough financing should be planned, fit, and reserves included. The things that remain after the loan is used up usually still have time. One example: when we moved in, we “lacked” a wood-burning stove, extractor hood, freestanding wooden bathtub, and a new wardrobe. So what? We’re buying these things now little by little, and I’m over the moon when I light the stove for the first time in winter after connecting it. It wouldn’t have been like that if we had everything from the start. The extractor hood and bathtub are still missing, so what? They can wait.

Many greetings

Good morning,

here is my calculation of the individual trades that I am to perform in EL.

Tiling work: Total €4200 (amounts rounded)

- 43m² floor tiles = €2400
- 33m² wall tiles = €1200
- interior window sills = €600
- including tile adhesive etc.

Floor coverings: Total €5500
- glued vinyl 138m² €4800
- baseboards €700
- again including material (adhesive, leveling compound, etc.)

Sanitary objects for 2 bathrooms: Total €3200
- included are: 2 open showers, bathtub, 3 washbasins, all fittings, 2x toilets

Painting work: Total €1000
- primer approx. €100
- rolled plaster for ceiling areas approx. €200
- paint €100
- wallpaper €600

Makes a total for the trades tiling, sanitary, painting and floor coverings

€13,900.

If in your opinion my estimates are not correct, please correct me!

I think you shouldn't let yourself get worked up. Of course, the rough financing should be in place, fit, and reserves planned.

Thank you for your opinion,

on the topic of reserves, I have to admit that I have only planned a reserve of €3,000 for any additional startup expenses (neighbors all had no problems with the startup, so I assume the normal case). Furthermore, I have planned €5,000 reserves for possible adjustments during the construction phase.

I think it is too little! What are your experiences?

Hello.

So all I can say is that we got our house (prefabricated house as a shell house, finished on the outside, with controlled ventilation) down to the exact euro amount as stated in the contract.

We awarded the heating/screed/electrical/water package ourselves. The execution was absolutely correct and the higher final invoice was only partly due to positions changed by us, e.g. a larger meter box, one more light switch in the basement, etc. Variable cost factors, e.g. approval of drilling, were pointed out.

The interior finishing (with partial own work) only became more expensive due to subsequently chosen different tiles/fittings.

Ultimately, the final invoices were only more expensive due to positions changed by us. And of course various things we did not think of. But there was the cost center "Baunebenkosten" [ancillary building costs] for that.

Conclusion: the ultimately higher prices were due to changes caused by us. Except for the civil engineering/earthworks...
And accordingly, building a house is always more expensive than planned.

Best regards

- 43m² floor tiles = 2400€
- 33m² wall tiles = 1200€
- interior window sills = 600€
- incl. tile adhesive etc.

Floor coverings: total 5500€
- glued vinyl 138m² 4800€
- skirting boards 700€
- again incl. materials (glue, leveling compound, etc.)

Sanitary fixtures for 2 bathrooms: total 3200€

Painting work: total 1000€
- deep primer approx. 100€

Add together for the trades tiles, sanitary, painting and floor coverings

13,900€.

If you think my estimates are not correct, please correct me!

hm, I calculate about 55 € per sqm for tiling. If the tile material is around 30 euros, it fits with tile adhesive etc, right? I don't currently know how much % is calculated for the adhesive etc, but this calculation would be possible.
I also see no problem with the vinyl.

But regarding the sanitary and painting items:
For sanitary, you have to include all the brackets, connectors, pipes and whatever else there is. Have you done that? Many people only look at the Reuter/hardware store prices for the ceramics, but not the "surroundings".

Your estimates for paint are a joke. That much is spent already on masking material.
We have been working on interior finishing for a few days now:
A bucket of good white paint 60 €, enough for a normal room;
roll of covering (felt) 15 €;
rollers, brushes, grids, sanding materials, etc. (consumables) currently about 40 €
various tools currently about 50 €
gloves, masks, etc. currently 20 €

it may be that you use all colored wallpaper... nevertheless, e.g. ceilings have to be painted, or wallpapered as well.

With the sanitary fittings, you have to include all the brackets, connectors, pipes, and everything else that comes with it. Do you have that? Many only see the Reuter/hardware store prices for the ceramics, but not the "extras around it"

For the sanitary work, all installation tasks are carried out by the contractor. The EL only refers to all ceramics, fittings, and washbasins. That means cisterns for toilets, etc., are not part of the EL. The prices are from a binding offer from a sanitary specialist shop / not a hardware store!

Your estimates for your paint are a joke. That already goes for masking material. We have been working on the interior construction for several days now: A bucket of good white paint 60 €, enough for a normal room; Masking roll (felt) 15 €; Rollers, brushes, grids, sanding materials, etc. (consumables) currently about 40 € Various tools currently 50 € Gloves, masks, etc. currently 20 €

The ceilings will be covered with ready-to-use roll plaster. Only the utility room will be painted (thus only little paint). All wallpapers are fleece wallpapers which are not painted. Necessary tools are already available.

However, I will calculate an extra 100 € for the consumables, thanks for the hint.
