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!

I’m missing both the current state and the target condition. To me, it looks almost identical, meaning it seems that a living room was enlarged by creating an opening into the garage and the bathroom was rearranged in a more modern layout (and probably a wall was removed where the kitchen island is now shown), but everything else still looks like typical 1960s design. And I share @dertills’s skepticism that this meets today’s energy efficiency standards.https://www.instagram.com/11antgmxde/

I had overlooked that the extension is only single-story. However, the increase from the dormers is also counted because a building permit / planning permission application is being prepared and it is considered one continuous construction project. Whether you stay under 50m² (540 sq ft) is something you’ll have to check yourself – and if you exceed it, just submit the application first and see what happens.
Where is all the money going? The extension should be around 50,000€ (about 54,000 USD). Then a new roof structure with roofing, another 70,000€ (about 76,000 USD). And the rest for the interior finishing?
If facade renovation is not yet included, that adds another 100-200€/m² (9-18 USD/sq ft). Either external thermal insulation composite system (ETICS) or ventilated facade with wood cladding or brick veneer. If you’re doing everything anyway and need a new heating system, you should aim to meet a KfW energy efficiency standard, as there are some subsidies available – but your energy consultant will likely explain that to you.
If the end result looks similar, demolition wouldn’t necessarily be required, especially if what remains is in good condition without construction faults or poor workmanship. I’m also more of a fan of renovations (we remodeled a 1959 bungalow last year ourselves – well below your renovation budget).

(We renovated a lower 1959 bungalow ourselves last year – significantly under your remodeling budget.) Is it posted in the house pictures thread?

but everything else looks like contemporary 1960s style.Could you explain what makes you say that? Apart from the wall thickness, I wouldn’t be able to tell from the floor plans whether it’s a poorly designed new build or a 1960s-era existing building.

Maybe I could have saved myself some work or found different solutions. But now it’s too late, though in time comes the house.
I do have a few pictures of the renovation—unfortunately far too few. When I have some time (haha, good one), I’ll post some before-and-after pictures. With a renovated old building, where we moved in with only a guest toilet and no kitchen (there was just screed on the floor and plastered walls), and the shower was only finished two days later (thankfully), I wonder when “after” actually is. When the baseboards are installed? Then you’ll have to be patient—today I spent the whole day working in the 2-meter deep (6.5-foot) trench around my basement.
