100 German Architecture & Construction Terms — A Cheat Sheet for Owners and (foreign)Architects
Whether you are a property owner navigating your first building project in Germany, or an architect who trained abroad and is now working with local planners and contractors: This list of 100 terms covers common words you will encounter; from planning law and building permits to construction details, technical standards, contracts, and trades. Use it as a cheat sheet when talking to your architect, engineer, or site foreman, or when you are just starting off as an architect in Germany and want to prepare yourself.
Planning & Permits
1. Bauantrag / Baueingabe — Building permit application: the formal submission to the local building authority to initiate the approval process for a construction project.
2. Baugenehmigung — Building permit: the official approval allowing a building to be constructed, altered, or extended.
3. Vorbescheid — Preliminary planning ruling: a binding decision on specific questions (permitted use, building size, location on plot) before the full permit application, particularly useful where no Bebauungsplan exists.
4. Bebauungsplan (B-Plan) — Zoning plan: a legally binding local plan that defines permitted uses, building footprint, height, density, and setbacks for a specific area.
5. Flächennutzungsplan (FNP) — A non-binding preparatory land use plan covering the entire municipality, showing intended uses for all areas.
6. GRZ – Grundflächenzahl — Site coverage ratio: the share of the plot that may be built over (e.g. GRZ 0.4 = max. 40% coverage).
7. GFZ – Geschossflächenzahl — Floor area ratio: total floor area of all storeys divided by the plot area; determines the permitted building volume.
8. Baugrenze — Building limit line: structures must not extend beyond this line. Minor projections such as balconies may be permitted.
9. Abstandsflächen — Mandatory setback zones between a building and the plot boundary, ensuring light, ventilation, and fire safety for neighbours.
10. Erschließung — The connection of a plot to public infrastructure — road, sewer, water, electricity — required before a building permit is granted.
11. Grundbuch — The land register: a public record of ownership, mortgages, and easements for every plot of land in Germany.
12. Baulast — A public-law obligation registered against a plot — for example, granting access across it or maintaining a certain setback on behalf of a neighbour.
13. Denkmalschutz — Listed building protection. Buildings of historic, artistic, or urban significance are protected; alterations require special approval.
14. Nutzungsänderung — A change of use: converting a building or space from its approved use (e.g. office to residential) usually requires a new permit.
15. Stellplatz — A designated parking space. German building law typically requires a minimum number of parking spaces per dwelling or use unit to be provided on-site.
16. Ausbau — Interior fit-out: the second construction phase covering plastering, concrete subfloor, flooring, windows, doors, plumbing, and electrics.
17. Renovierung — Cosmetic renovation: surface-level improvements such as repainting, new flooring, or replacing fixtures — no structural work involved.
18. Sanierung — Comprehensive refurbishment addressing structural, technical, or energetic deficiencies — goes significantly beyond cosmetic renewal.
19. GEG – Gebäudeenergiegesetz — Germany's Building Energy Act, setting minimum energy efficiency requirements for new buildings and major refurbishments.
20. Energieausweis — Energy performance certificate: mandatory for all buildings when sold or rented, showing the building's energy demand or consumption.
Construction
21. Tragwerk — Load-bearing structure: the entirety of structural elements (columns, beams, slabs, walls) that transfer all loads safely to the ground.
22. Bodenplatte — Ground slab: a reinforced concrete slab that forms the foundation of a building, distributing loads evenly across the subsoil.
23. Streifenfundament — Strip foundation: a continuous concrete footing running beneath load-bearing walls, transferring their weight into the ground.
24. Stahlbeton — Reinforced concrete: concrete with embedded steel reinforcement bars, combining concrete's compressive strength with steel's tensile strength.
25. Mauerwerk — Masonry: a construction method using bricks, blocks, or stone bonded with mortar; the most common wall construction type in Germany.
26. Holzrahmenbau — Timber frame construction: a building method using a structural framework of timber studs and panels, common in residential construction.
27. Estrich — Concrete subfloor: a smooth layer of concrete or mortar poured over the structural slab as a base for the final floor finish (tile, parquet, etc.).
28. Dampfsperre — Vapour barrier: a layer within the building envelope that prevents moisture from penetrating into insulation or structure, avoiding condensation damage.
29. Wärmedämmung — Thermal insulation: material applied to building elements to reduce heat loss and lower energy demand for heating.
30. U-Wert — Thermal transmittance (U-value): measures how much heat passes through a building element; the lower the value, the better the insulation.
31. Luftdichtheit — Airtightness: the quality of the building envelope to prevent uncontrolled air leakage; essential for energy efficiency and mould prevention.
32. Abdichtung — Waterproofing: protective layers applied to building elements exposed to water, such as basement walls or flat roofs.
33. Sturz — Lintel: a horizontal structural element above a door or window opening that carries the load from the wall above.
34. Ringanker — Ring beam: a continuous horizontal reinforced concrete element that ties the outer walls of a building together, preventing cracking.
35. Attika — Parapet: the upstanding wall at the edge of a flat roof, forming a visual termination and acting as a safety barrier.
36. Rohdecke — Raw ceiling slab: the structural concrete ceiling in shell construction, before concrete subfloor and finishes are applied.
37. Wandaufbau — Wall build-up: the layered construction of a wall (structure, insulation, finishes), determining thermal, acoustic, and moisture performance.
38. Fassade — Facade: the exterior face of a building; encompasses cladding material, windows, and any applied insulation or ventilation layer.
39. Dachaufbau — Roof build-up: the layered construction of a roof (structure, vapour barrier, insulation, waterproofing, finish), relevant for both flat and pitched roofs.
40. Absturzsicherung — Fall protection: measures required by law to prevent people from falling from heights, e.g. at open edges, roof terraces, or stairwells.
41. Geländer — Railing / handrail: a protective barrier along stairs, balconies, or elevated edges; height and load requirements are defined by building regulations.
42. First — Ridge: the highest horizontal line of a pitched roof, where two sloping roof surfaces meet at the top.
43. Traufe — Eaves: the lower edge of a pitched roof where rainwater drains off; the eaves height is a key dimension in planning applications.
44. Ortgang — Verge / gable edge: the sloping edge of a pitched roof at the gable end, perpendicular to the ridge and eaves.
45. Bodentiefes Fenster — Floor-to-ceiling window: a window that extends from floor level to the ceiling, maximising light and creating a visual connection to the outside.
46. Brüstung — Parapet / balustrade: the solid wall section below a window, or the low protective wall at the edge of a balcony or terrace.
47. Dachflächenfenster — Roof light / skylight: a window installed flush within a pitched roof slope, bringing daylight into attic spaces.
48. Balken — Beam / joist: a horizontal structural timber or steel member spanning between supports, carrying floor or roof loads.
49. Stütze — Column / post: a vertical structural element transferring loads from beams or slabs down to the foundation.
50. Treppe — Stairs.
51. Tür — Door.
