HHS Planer Architekten AG

What HHS Planer Architekten AG does

HHS Planer + Architekten AG is a privately held German architecture firm founded in 1980 in Kassel, operating as an Aktiengesellschaft with approximately 12 employees. The firm delivers full-service architectural and interior design work for new construction, renovation, and urban planning across residential, commercial, educational, cultural, and infrastructure projects, with a documented specialization in sustainable and energy-efficient building design. Its core technical capabilities include Building Information Modeling (BIM) for digital planning, integral planning methodology from project inception, building-integrated photovoltaics, plus-energy building standards, and lifecycle cost optimization. The firm works to DGNB and QNG (Qualitätssiegel Nachhaltiges Gebäude) certification standards and has delivered reference projects including the Aktiv-Stadthaus Frankfurt (a 74-unit plus-energy residential building) and the Energiebunker Hamburg (85% renewable heating, ~95% CO2 reduction versus conventional benchmarks).

The firm's revenue model is professional services: project-based architectural fees negotiated individually with clients, with no disclosed pricing model or recurring revenue streams. Distribution is direct to enterprise and public-sector clients — including federal ministries (BMVBS), municipalities (Stadt Kassel, Stadt Hamburg, Stadt Frankfurt), and corporate clients such as Fraunhofer-Gesellschaft, SMA Solar Technology, Stiebel Eltron, ABG Frankfurt Holding, and Nassauische Heimstätte — typically secured through architectural competitions, public tender, and referrals. Its GTM motion is enterprise field sales, supported by earned media from awards, professional chamber activity (Gerhard Greiner elected President of Architektenkammer Hessen in 2024), and a project portfolio on its website. The firm has executed projects outside Germany (Finland, Switzerland, France), but the overwhelming majority of its work is delivered within Germany. Ownership is closely held among founding families and current board members (Johannes Hegger, Ilka Berger, Guido Höfert, Andreas Wiege), with no institutional investors, parent company, or publicly traded equity.
