Logotype for a sanitary
installation specialist
The project was created for a specialist who works under the name Dudziński Serwis and provides sanitary installation services. The logotype was intended to organise the visual identity after the name change and reflect a way of working based on cleanliness, order and a high standard of workmanship.
¶ All letters in the logotype were designed and drawn from scratch, rather than set in an existing typeface. The clean sans serif construction was complemented by individual details designed specifically for this mark. The first letter of the logotype, D, is read as the initial of the name in the full wordmark, while as a separate element it functions as a D and S monogram and as a standalone form for use as a social media avatar.
