Hello everyone,

After much consideration, we have decided to move away from the idea of building a new house and will instead renovate and convert a detached single-family home (fully brick-clad) with a basement apartment (built in 1982).

Specifically, we are planning the following:

A basement extension at the front of the house

An additional floor in the upper story including a new floor structure to create two extra children’s bedrooms

Demolition of some interior walls to enlarge the kitchen

Partial demolition of the roof structure

Partial removal of a typical, bulky 1980s fireplace, which will be reused in a simplified form

Installation of a new heating system

Replacement of all windows and doors

Energy-efficient renovation of the entire roof

Renewal of all floor coverings and interior plaster throughout the house

Enlargement of an existing bathroom on the upper floor

Renewal and extension of the entire electrical installation

New underfloor heating throughout the upper floor (existing underfloor heating on the ground floor will remain)


New paving for paths, as well as new driveway and parking space

The entire upper floor (existing and new addition) as well as the extension will have a ventilated facade using Trespa panels


Attached you will find floor plans and elevations.

What is your opinion on the planned changes so far? What is feasible, and what might not be?

We look forward to all comments, suggestions, ideas, and improvements. Thank you in advance!

Have a nice Pentecost weekend

Who is responsible for the renovation planning? It looks somewhat questionably professional to me:

I interpret the 33cm (13 inches) wall thickness as the "structural dimension including facing bricks on the exterior," built monolithically. The 13cm (5 inches) interior wall thickness doesn’t make much sense to me.

The floor plans are a bit confusing. Unlike the roughly north-oriented ground floor and upper floor, the basement seems to be oriented east(?) and the staircase there is spiraled in the opposite direction at the start.

I don’t see the demolition for the kitchen enlargement marked. In the elevations, it’s not clear to me how the existing structure and amendments relate to each other. Maybe you could add some photos.

Here I am again: the house looks familiar to me from your thread https://www.hausbau-forum.de/threads/1-architektenentwurf-umbau-eines-efh-eure-meinung-ist-gefragt.23910/ from 14 months ago.

At that time, the entrance extension was not yet discussed in terms of its basement, which I also do not consider practical, and

expresses more clearly, in my opinion, how the creation of the new children's rooms should be understood.
