New build
A house on an open plot. Design, permit drawings, building description and structural proofs are produced side by side, so that every document describes the same building.
Ingenieurbüro Konrad Smoczynski
We design your project, draw the permit documents, calculate structural safety and thermal performance, and file the complete set with the building authority. You hold one conversation instead of ten.

The office in brief
Telephone +49 2432 907 93 00 On working days, usually within one working day.
01Projects
Which route applies is decided by the project, not by preference. We place yours in the first conversation and tell you what the building authority will want to see.

A house on an open plot. Design, permit drawings, building description and structural proofs are produced side by side, so that every document describes the same building.

An extension, an added storey, a new opening in a load bearing wall. Here the existing fabric decides: it is surveyed, drawn and carried into the calculation.

A barn becomes living space, a shop becomes an office. The application settles whether the new use is permitted in that location and which requirements then apply.
A quick question
Not sure where your project belongs? Two sentences are enough for a first answer.
02Steps
Six steps in this order. At each of them you hear what is happening and what is needed from you next.
01
You describe the project. We say which procedure is likely, whether a preliminary enquiry is worthwhile and which documents you need to obtain.
02
Floor plans, sections and elevations are produced and agreed with you. At this step changes are still quick to make.
03
The design becomes drawings at the required scale, together with the building description, floor areas and gross volume.
04
Structural safety and thermal performance are calculated and added as checkable documents, matched to the building services planned.
05
The set is checked for completeness, signed and filed with the responsible building supervision authority.
06
We answer any queries from the authority and file whatever is missing until the permit is granted.
03Documents
An application is assembled from two directions. You obtain one part, the office produces the larger part. Exactly what your project needs depends on the procedure.
Special buildings, sites outside settlement areas and changes of use call for further documents. We tell you which ones before anything is commissioned.
04Services
Design, permit documents and calculations are produced in the same office. That spares you the coordination between several parties and stops the drawings and the structural work from saying different things.
Service 01
Detached and apartment houses, from the first conversation to the agreed design.
Service 02
Drawings, building description, calculations and forms as one complete set.
Service 03
Settles the decisive question about the plot before the full application creates work.
Service 04
Structural calculations, member layout drawings and later the construction drawings for the site.
Service 05
Proof for the envelope and the building services, matched to the heating that is planned.
Service 06
Existing buildings are measured and digitised when drawings are missing or no longer correct.
Service 07
On request, site management or site supervision in building construction and structural engineering.
Service 08
Concept and calculation for components that no catalogue covers.
A quick question
Not sure which of these your project needs? Asking costs nothing.
05Pictures
Five pictures from around a building application: from the design on the model and the survey on the plot to the reinforcement in the foundations.





The pictures show typical construction stages and working steps. They illustrate the services described.
06Credentials
A building submission is only accepted when it carries the signature of a person authorised to sign it. That authorisation is registered here and carries a number.
07Enquiry
Your name, a telephone number and a few sentences are enough. We will come back to you and say which procedure is likely, which documents are needed and what they would cost.
The enquiry commits you to nothing. You receive a written offer with the scope of work and the fee under the HOAI scale before anything is commissioned.
08Area
The office sits in Wassenberg, a good twenty minutes from Heinsberg. We file building applications for the district town of Heinsberg, for its villages and for the towns and municipalities of the Kreis Heinsberg district.
Places we submit for
New houses in Heinsberg, Wassenberg, Hückelhoven and Erkelenz are among the projects the office has accompanied so far.
09Questions
Seven answers to the questions that come up most often before a commission.
In North Rhine-Westphalia building submissions for a building must be signed by a person holding submission rights. Those rights are held here and are registered under the number V3693.
That depends on size, use and location. Some work needs no permit, some runs through a simplified procedure, some needs the full application. Describe your project and we will place it.
A query is normal and is not a bad sign. We answer it, complete the document and file it. You are told where things stand without having to chase us.
From the land registry office or from a publicly appointed surveying office. We tell you which version your procedure requires, so that you do not order the plan twice.
Yes. Permit drawings and the structural proof are produced here side by side. That is why the drawing, the member layout and the calculation agree instead of contradicting each other.
Whenever it is unclear whether the plot may be built on in that way at all. It settles that one question before the full documents are prepared.
On request the office itself: site management or site supervision in building construction and structural engineering, together with the construction drawings for the site.
