Estimating renovation costs of a single-family house from 1965

Hello everyone,

We looked at a single-family house from 1965 over the weekend. Hillside location, 150 sqm living space, 60 sqm usable space in the basement partially converted for living, energy class F. Although some work has been done on the house over the years and the seller says one could move in immediately, that is of course rather not the case.

What definitely MUST be done immediately for us:

- Electrical wiring (still 2-core throughout the entire house) (20K€?)
- Radiators (-> install underfloor heating, i.e. also new screed) -> (?€)
- Flooring ~170 sqm -> would like floorboards (20K€?)
- Interior doors (front door is fine, about 10 pieces) (5K€?)
- 1 of 2 bathrooms (~10 sqm) completely, new furniture in the second bathroom (recently re-tiled / sanitary fixtures installed) (15K€?)
- 2 openings, one potentially through a load-bearing wall (each about 10 sqm wall) -> ?€
- Kitchen (15K€?)
- Facade insulation? Currently energy class F with brick facade, windows are all double-glazed and from different years. (?€)
- New windows/doors facing the garden (15K€)
- Wallpapering and painting 150 sqm living space (€?)

What will arise over the next few years:
- Heating system is from 2013 and still oil -> sustainable heating system (e.g. pellets for ~35K€? - there would be enough space)
- Roof is largely uninsulated (attic was amateurishly insulated by the owner himself) and still original tiles (45K€?)
- Occasionally one or another window.

Since we are expecting a second child this summer, we do not want to do any of this work ourselves. The maximum idea would be to lay the floor or wallpaper/paint - more simply won’t work time-wise.

Are these estimates roughly in line or do they balance out where I am way off? What about the topics where I have no estimate?

Thank you very much!

All floor plans and a gable-parallel section could significantly clear up my crystal ball. 1965 is already quite okay.

and the seller says you could move in immediately.

Ask him what the Federal President's name is - Heinemann?

Floor plans: here you go :) - I don't have a section. The small extension drawn by hand in the ground floor and attic plan at the top left is a small annex. In the attic plan at the bottom right, there is still a large dormer drawn in. In the basement, for me only the room on the right is living space; the other room labeled "Zimmer" is currently a workshop. The bathroom in the basement is old, but we would (for now) leave it as is. The bathroom in the attic is bigger than in the picture (it was extended under the slope and towards the left room), with a shower in the corner where the door is currently drawn.

The idea would be to create openings from the kitchen in the ground floor plan at top left to the living room and between the living room and the mother-in-law’s living room.

I cannot say anything about the general renovation costs, but if you install underfloor heating, you use a heat pump and not pellets. And that will also be cheaper than 35, I would estimate around 20-25, then there is also funding.

I don't have a cut.

In this case, not so bad, since a ceiling plan is apparently integrated into the ground floor layout. So reinforced concrete ceiling, that already looks good. And I am optimistic about the breakthrough to the kitchen.

What is hand-drawn at the top left on the ground floor to attic plan is a small extension.

So a windbreak is to be attached in front of the current kitchen entrance area and a children's room is to be added on top of it? - Be careful not to build over any pipes - where is the house entry? I interpret your descriptions and the drawings in the direction of a probably monolithic exterior wall, take some facade photos of all sides for that.

So a vestibule should be added in front of the current kitchen entrance area and a children's room should be added on top of it? - Be careful not to build over any pipelines - where is the house entry point?

No, the extension already exists.
