Who we are
Urbanstreet is an owner-led group for real estate development, integrated planning and owner's representation, based in Küsnacht near Zurich. The operating company is Urbanstreet AG, founded in 2025 and backed by Urbanstreet Development AG with thirty years of experience in architecture and development. We work for investors, institutional owners and developers — from potential analysis through feasibility and planning permission to delivery.
We think like developers and act in the owner's interest.
Thirty years of architecture taught us how a building comes into being. Development taught us where a project fails commercially. Combining both perspectives under one responsibility is the core of our work — and the reason we take the lead on a project rather than deliver a partial service.
We lead what determines cost, schedule and quality: procurement, variations, negotiations with authorities and the interfaces between everyone involved. Capacity we buy in. Responsibility we do not hand over.
We know both sides of the table.
The owning family is entrepreneurially active in construction and real estate and develops projects of its own. That sharpens our judgement on risk, cost and return — and we say so openly: in mandates for third parties we act exclusively in their interest. The role we take in a project is set out in writing before we start.
Services
Three pillars, one responsibility.
Each pillar rests on a different kind of proof. Development shows in how you read the site, owner's representation in the state of the works, integrated planning in the joint. That is why you will not find a façade gallery here, but for each pillar the image that proves it.
Strategic development
- Location and potential analysis
- Feasibility, use concept, product definition
- Financial viability and project structuring
- Planning law optimisation, strategy with authorities
- Pipeline building for investors and family offices
Project leadership and owner's representation
- Representation towards planners, contractors and authorities
- Control of cost, schedule, quality and risk
- Procurement, contract and variation management
- Negotiation with authority to instruct
- Full relief for the owner
Integrated planning and architecture
- Design, building application and execution planning
- Leading all specialist engineers under one responsibility
- Landscape and outdoor design
- BIM, digital twin, data-driven analysis
- Interface to contractors and construction
What others hide is our argument.
Every architecture practice shows the finished façade. An owner's representative is paid for the road to it: excavation, barrier tape, deliveries, unfinished surroundings. Drag the slider and see both states of the same project.
The two photographs were not taken from an identical position. Future sites will be photographed from a marked fixed point so the comparison becomes exact.

Who we work for
Three client groups, clearly prioritised.
Investors and family offices
Capital is looking for permit-ready projects and finding too few. We build development pipelines, assess opportunities and structure projects so they become investable.
Institutional owners and developers
For portfolio holders and developers without their own architecture and development unit we take on early phase, integrated planning and owner's representation as one managed service.
Private owners, selectively
On Zurich's Gold Coast we support selected private clients with replacement buildings, demanding conversions and overall coordination — with direct personal responsibility.

Projects
Thirty years of built substance.
Urbanstreet grew out of rd2b limited, founded in 1996 — with buildings in Switzerland and Brazil. From those years comes the conviction that a project rarely fails on design, but on leadership, cost and time.

Also from three decades: Swiss Consulate General São Paulo · Microncity, Nidau · the 24Hour City concept at Zurich Airport · construction management of a townhouse on the Upper East Side, New York.
Method
Technology for precision. People for judgement.
Feasibility, plot ratio, income scenarios and option comparisons are calculated with data — in days rather than weeks. Not for its own sake: the earlier reliable figures are on the table, the cheaper decisions become. The time saved goes where nothing can be automated.
Three options for the same site, calculated and visualised in parallel: overall scheme, residential courtyard, terraced position. The owner decides on the image, not the memo.
Plot ratio, use and income options are calculated in parallel instead of sketched one after another. You see early which option carries — and which you can skip.
BIM and digital models connect design, cost and schedule. Deviations become visible while they can still be corrected.
We run an AI-supported knowledge network for construction and real estate and advise companies on using these tools. Thirty years of experience become retrievable instead of tied to individuals.
Negotiations with authorities, a feel for building culture, weighing risk and personal accountability towards the client cannot be delegated — to no one and to nothing.
Working together and fees. We do not work on open hourly rates, but with a running base service, fixed-price project phases and a share in the outcome. The structure suited to your project is set out openly and in writing before we start.
Structure
One operating company, backed by thirty years of substance.
Urbanstreet AG runs the operating business: planning, development and marketing. It is backed by Urbanstreet Development AG, which holds the experience, the network and the family's long-term perspective. The second generation holds an entrepreneurial stake in the operating company — continuity here is a question of ownership, not of intent.
