Hello!
Since this is an extension, I can’t answer most points of the profile properly or only insufficiently. So I’ll simply describe my situation as it is. If this is not desired for clarity reasons, I can of course take the time and try to fill out the profile. My first attempt just now was rather pointless
Attached you’ll find a draft created by the architect. The changes to be made are marked in red. The extension is on the upper floor, identical to the already existing extension on the ground floor (where the building is being raised accordingly).
What is still missing there is that the wall in the original building between the hallway and child’s room 2 is to be shifted about 1.5m (5 feet) to the right according to the plan, so that child’s room 2 becomes larger. I hope you understand what I mean. All doors remain as they are, only the hallway passage from the original building to the new extension will be narrower.
We were actually quite satisfied with the plan. Cost estimate: €150,000
Detailed breakdown (offers available)
- ~€58,000 Timber frame construction including roof structure, insulation, exterior sheathing panels, and all related work
- ~€12,000 Windows and doors
- ~€25,000 Underfloor heating, plumbing, bathroom including stretch ceiling with lighting (bathroom only)
- ~€15,000 Floor coverings including screed boards, wallpaper, and paint (all including installation)
- ~€5,000 Electrical installation (a lot of own work)
- ~€15,000 Measures on the existing building including protection during construction phase
- ~€10,000 Roof terrace on existing garage including stairs to the garden
- ~€10,000 New kitchen
Now it seems that we want a third child. Then there will be no space for another child’s bedroom again. I simply can’t imagine this with the existing plan. If at all, it would have to be the living room area that is already partly separated by the partition wall, although this would make the living room feel very narrow, which we don’t like even in theory.
On the ground floor, an (unapproved) conservatory has been built on the upper side of the plan, measuring about 10 by 2.5m (33 by 8 feet).
My idea is to give this a foundation and erect supporting pillars, so that the upper floor would have a gross floor area of 10 by 9.5m (33 by 31 feet) instead of 10 by 7m (33 by 23 feet). Structurally this should be fine. Then the separated living room area could indeed be used as a master bedroom, leaving a 6 by 5m (20 by 16 feet) living room. The kitchen would also be about 5 by 2.5m (16 by 8 feet) bigger, which could create a pantry or something similar, or a covered balcony by the kitchen (I would really like that for an outdoor fryer => no odors in the open kitchen,...).
The existing conservatory could remain as is; glass elements would just need to be installed between the new supporting pillars.
Cost estimate: With an additional 20m² (215 sq ft) of living space, I would estimate the project would then cost about €200,000 instead of the planned €150,000.
What do you think? Do you have better ideas? Do you consider the costs realistic? I mean, I do have the offers, but maybe something essential is missing?
Are you missing important information or do you insist on the profile? Just let me know
Thank you very much. We look forward to your feedback and ideas!

Unfortunately, I’m not good with structural engineering and probably lack the imagination for it.
If you remove half of the exterior wall, the ceiling would still remain. It would need to be supported by beams, which might be supported by an additional column. At least, that’s what I thought. The ceiling height continues smoothly in the architect’s extension, so in my opinion, the roof would undergo the same changes or remain unchanged just like in the architect’s design. In other words: with or without the exterior wall, the roof and ceiling are the same in both designs. Where is my mistake in thinking?
And I don’t understand why you want to remove the underfloor heating just because of the wall. You only need to reroute the supply line. That can’t be that difficult, can it?
Well, maybe the devil is in the details. The information is simply too limited. It’s best to talk to the architect. Maybe you’ll share what they say with us. That would be great.
