Hello everyone,

we would appreciate your feedback on our current plans.
The project involves the renovation of a 1960s suburban house with a small extension. The property will undergo a complete refurbishment, from the basement to the roof. Our main goal is to remodel the house in a modern and open style. However, we are constrained by certain structural conditions, as this is not a new build.
A detailed bathroom plan is still to be developed; the current plan only includes the standard essentials.

Development Plan / Restrictions
Plot size: 700 m² (7,535 sq ft)
Slope: no
Site coverage ratio: 0.25
Floor area ratio: 0.5
Number of parking spaces: 2
Number of floors: 1
Roof type: gable roof
Style: suburban house
Orientation: north-south
Maximum height / limits: 9 m (30 ft)
Other requirements: roof pitch 35–50 degrees

Client Requirements
Basement, floors: basement yes, one full floor, attic with dormers
Number of residents: 3
Office: family use
Open or closed layout: open
Conservative or modern style: modern
Open kitchen, kitchen island: both
Fireplace: included in the plan, between the dining room and extension
Balcony, roof terrace: no
Carport: possibly in front of the house, but space is tight because of the kitchen window

House Design
Planned by: architect
Cost estimate according to architect: €450,000
Personal budget for the house including fixtures: €300,000
The house already belongs to us; our budget applies only to the renovation and extension.

Thank you very much for your feedback!

Could you explain what you base that on?

A housewife just has a feeling for it, as Loriot said.
I have been working with floor plan design for almost forty years, and every era has its own style and construction techniques.

Apart from the wall thickness, I couldn’t really tell from the floor plans whether it’s a poorly designed new build or a 1960s old building.

The 24 cm (9.5 inches) wall thickness can be quite precisely placed in this period; 1960 still belonged to the 1950s in that sense. Shortly afterwards, 30 cm (12 inches) walls became more common.

Poorly designed new builds, by the way, are a very recent trend; they were very rare in the 1960s. I don’t use the term "old building" for properties from this period; it usually refers to those built before 1948.

Now it’s too late,

For the house pictures thread, it’s definitely not too late — it’s perfectly fine if much or even all of the construction is already finished. It is not just a foundation slab thread.

@kaho674: Thank you for the feedback, that makes sense to us as well.

I have uploaded the plans here, which also show the existing building.

Our question regarding demolition and new construction is whether our budget would even be sufficient... For demolition, I would estimate around 20,000 to 25,000 € (approximately 22,000 to 27,500 USD), does that sound roughly accurate? That would leave 275,000 € (about 302,000 USD) for the potential new build. A basement is already in place. Our own work would mostly be limited to demolition-related tasks.

From what I see, besides the living room extension and a major enlargement of the dormers (are you sure the building permit / planning permission will allow that?), there are only demolitions and relocations of non-load-bearing walls. Where exactly is a budget of three briefcases worth of money supposed to be spent?
