Two design packages
- Architecture and site layout — 55 €/m². Floor plans, sections, elevations and the site plan: placement on the plot, access and landscaping.
- Full design — 75 €/m². Architecture and site layout plus structural design and engineering systems.
What affects the price
- Floor area. The price grows with the square metres, so a compact, well-planned layout saves money in both design and construction.
- Scope. If another specialist designs the structures or engineering systems, the architecture and site layout package is enough.
- The plot. Slope, building restrictions and utility connections determine how much has to be resolved.
Design cost versus construction cost
Design is a small part of the total cost of a house, but it is where the construction cost is decided: floor area, structure, materials and engineering systems. Fixing a mistake in the design is cheaper than fixing it on site.
