ᐅ Floor Plan Optimization (Extension, Additional Storey)

Created on: 28 Mar 2020 10:11

Hello dear community!

I am new here, so please forgive me if I haven't included all the information right away. I can provide additional details if needed.

We are currently working on finishing the upper floor and also expanding it slightly. There will be a separate entrance, meaning the parents will live downstairs and we with our family upstairs.

I have roughly followed the guidelines. I hope the information provided is sufficient, but as mentioned, I can add more if necessary.

The basement already exists.

What do you dislike? Why?
Cost estimate according to architect/planner:
Personal price limit for the house, including equipment:

If you had to give up something, which details / extensions

Why did the design turn out this way? For example:
Standard design from the planner?
Which wishes were implemented by the architect?
Bedroom, dressing room, and master bathroom

A mix of many examples from various magazines...
What makes it particularly good or bad in your opinion?

What is the most important/basic question about the floor plan summarized in 130 characters?

I am basically satisfied with the initial plan. I would like to get some tips from you. I have summarized some important points here:

I would like the kitchen and living room to be separated by a fireplace and not have direct access from the cloakroom to the living room. I want the living room to be a retreat room, not a passageway. But I’m not sure how much can be done since the chimney connection is already available. We could extend the angled wall further to gain more space.
Do you see an issue if you always have to walk through the living areas to get to the children’s rooms? Considering teenage years?
The terrace shown in the plan is much too small. It needs to be at least 30sqm (323 sq ft). Southeast or southwest orientation?
The dressing room will be separate from the bedroom since we both work shifts and don’t want to disturb each other when getting dressed.

Upper floor
Gray walls are existing
East and south sides face municipal streets

I’m aware that the options are relatively limited due to the existing structure. Nevertheless, I look forward to your suggestions and tips.

Best regards

Could you also share the floor plan of the ground floor? Are the exterior walls planned to be expanded there as well?

@11ant probably wants to point out that for such renovations on the upper floor and likely on the ground floor too, a demolition and rebuild (with fewer complicated 1980s angled walls and a less complex roof structure) would be the more cost-effective option... not to mention the advantage of a better layout.

I didn’t understand that either. It looks like the new upper floor is partially larger than the old one and extends beyond the ground floor. Is that intentional, and does it actually work?

This is the ground floor. My parents do not want to enlarge the house – possibly they would be willing to expand the kitchen. It’s not that simple, as the boundaries must be respected and the building is, as you said, very intricate. I would like a larger living room and kitchen, and I think this would require extending further outward. Part of the extension would be built using timber framing.
Thank you for your help.

Yes, that’s how it’s supposed to be. We need to create more space upstairs.

You might "need" more space, but not in this house.

Generally, yes and no; economically, absolutely never. The extension (excluding the garage and excluding the dismantling, storage, and reassembly of the existing roof structure—which I’ve already mentioned only partially covers the "stairwell") costs about as much in euros as the entire house cost back then in German marks.

My parents don’t want to enlarge the house – maybe they would agree to expand the kitchen.

But they are willing to accept the shading that a roof level extending out like claws over their living floor will cause, and to essentially allow you to turn their lovely house into an above-ground partial basement for a penthouse with a larger footprint? If so, I hope you are an only child; as a sibling sharing the inheritance, I would seriously question their soundness of mind at this point.

I never said it was awkwardly shaped. The house as it stands has a charm—not to my taste, but it definitely has its market niche. Adding a Frankenstein-style treehouse on top will destroy that charm, and even Horst from "Cash in the Attic" wouldn’t like it anymore. Your "concept" of building a separate attic at the limits of the building envelope—hopefully, aesthetics being one of the criteria and compliance with building regulations not the only frame—will likely not be approved; the principle that "perverse costs extra" would certainly be evaluated by the book. The wishful thinking that using timber construction for the cantilevered parts could statically save this crazy idea will not work.

Generally, it’s a yes and no, economically speaking definitely never ever. The extension costs (excluding the garage and excluding dismantling, storage, and reassembly of the existing roof structure – which I already mentioned only partly covers the “stairwell”) – about as much in euros as the entire house used to cost in deutschmarks.

But they are willing to accept the shading that a protruding attic, like claws of a prostitute, will impose on their living floor and to effectively provide you with their beautiful house as an above-ground partial basement of a penthouse with a larger floor area? – then I hope you are an only child; as an inheriting sibling, I would seriously question their full mental capacity at that point.

I never said the house was cramped. The house, as it stands, has a charm that isn’t to my taste but certainly has its market niche. By adding a Frankenstein treehouse-style extension, you completely destroy that — it wouldn’t even please Horst on “Bares für Rares.” Your “concept” of building an attic separately right up to the edges of the building window (building envelope) is hopefully not approvable — aesthetics are one criterion, but compliance with the building envelope is not the only framework. The principle “perversely costs extra” would certainly be evaluated exemplary in this case. The hopeful idea that constructing the projecting parts in timber would somehow statically save this crazy plan won’t work.

Our alternative: a building plot of 500sqm (5382 sq ft) for 425,000? So this option is definitely preferred by us and economically more sensible.
