CARLO Design was founded in Berlin in 2015. The city has been our home and our largest body of work, over forty private homes across Mitte, Prenzlauer Berg, Charlottenburg, Wilmersdorf, Friedrichshain and beyond.
Architect Charlotte Wiessner founded CARLO Design in 2015. Our Berlin studio is led by Andrea Tomasena, with architects and designers on the ground in Mitte. We work with carpenters, stuccateurs, parquet specialists and trades whose names we know personally, relationships that take years to build and cannot be replaced by a directory.
We design private homes from first sketch to final furnishing, architecture, interiors and the construction phase that brings them together.
New builds, extensions and full reconstructions of Altbau and Gründerzeit properties. We handle Bauantrag, HOAI Leistungsphasen 1 through 9, and coordinate with engineers and Bauamt.
Learn moreSpatial layouts, custom joinery, lighting and furnishing, preserving original stucco, parquet and tile stoves where they exist, and integrating modern requirements without compromise.
Learn moreOn-site coordination, scheduling, quality control and budget tracking. We work according to HOAI Leistungsphase 8 with trades we have built relationships with over a decade.
Learn moreBerlin has no shortage of design studios. Here is what makes our way of working different, and why most of our new projects come through client referrals.
Architecture, interiors and construction managed by the same studio. No handoffs, no lost intent, no coordination gaps between trades.
Most of our Berlin work is Gründerzeit, Wilhelminian and Altbau. We know how to preserve original stucco, parquet and tile stoves while integrating modern systems invisibly.
We hold our own permit signature in Berlin. Bauantrag, statics coordination, energy certification, all handled in-house from concept to final acceptance.
Carpenters in Wedding, stuccateurs in Pankow, parquet specialists in Lichtenberg, electricians who pick up on weekends. Personal relationships, not lowest bidders.
Recognised consecutively from 2017 through 2026. Featured in AD, Bauwelt, Bundesstiftung Baukultur and Cube Magazine. Substance over noise.
Andrea or Charlotte are reachable directly. No account managers, no project hand-offs to junior staff once the contract is signed.
Across our two studios, most of our new work comes through recommendations from past clients. 5.0 stars on Google, 5 reviews for our Berlin studio.
