We have a few questions regarding our architect, their cost estimate, and their overall approach. We are currently in phase 2; planning the major renovation and a 40% increase in living space for our 1960s house. We have attached the cost calculation we received after 4 weeks of processing, as there are several points we find unclear. We have already discussed this with the architect, who also cannot explain the high costs. The costs seem disproportionately high to us. At the start of the planning, we had budgeted €500,000. How should we approach this? Is it realistic to expect the total to get close to €600,000? In that case, we would have to cut many things that we actually want to keep. Our original goal was to expand the living space and not to completely abandon the extensions and only carry out a major renovation. Does this cost estimate make sense to you? We look forward to your comments.

The architect will be able to explain in detail how the individual trade costs were determined upon your request—provided that a corresponding, detailed preliminary design stage (LPh 2) with quantity surveying (partial service LPh 6) has already been completed.
- How many m² (square meters) of heated net floor area/living space in your existing property are planned for renovation?
- Will the floor plans be significantly altered / will structural changes be made?
- Will the roof frame be completely replaced / will the attic be converted?
- What is the size of the planned new build (net floor area/living space)?
New construction and building renovations have become significantly more expensive over the past three years. It is no coincidence that your architect rightly added the note "excluding inflation surcharge during planning and construction phases" at the end of the cost estimate. Construction costs depend on the size and condition of the property, the client’s requirements, and the wages and material prices, which the architect cannot influence.

When we decided to part ways, he was completely “sure” that he had delivered everything up to design development (phase 3 of the services)…
It was an expensive but worthwhile separation.

Gerddieter4 May 2024 21:45I just checked the items I rated myself and have to say—without knowing your project, flooring and painting actually seem rather low to me... For us, flooring including quality parquet was 100 €/m² (approximately 9.3 $/ft²) all inclusive, and painting work such as filling, plaster fleece, and silicate coating was about 35 €/m² (approximately 3.2 $/ft²) per wall or ceiling.
