Benefits for architects and developers

Very considerable time savings

Developers spend a good third of their time looking for, comparing and selecting suitable building products. With us, you can find all of the relevant information centrally on a single platform, which makes your workflow significantly faster.

Comprehensive planning reliability

Construction defects cost 1.4 billion euros every year in Germany and the primary cause is out-of-date technical manuals and analogue planning data. Plan.One offers you digital access to building product information directly from the manufacturer.

Transparency across the market

The product descriptions and property values of the products we list are standardised by us. This enables us to compare all manufacturers based on objective evaluation criteria.

Products to suit requirements

Plan.One uses all of the search queries made to calculate trend forecasts, which enable manufacturers to tailor development of their products to suit you. Use Plan.One as a mouthpiece to the manufacturer.
