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.
Origin
Zurich and São Paulo, since 1996.
ZurichKüsnachtSão PauloRio de JaneiroNew York
On 1 October 1996, Patrick and Sandra Hüppi founded an architecture practice in Zurich. In 2003 it was converted into a stock corporation as rd2b limited — and in the same year rd2b limitada in São Paulo was founded as a subsidiary in Brazil.
For almost thirty years the two led the practice together, with buildings in Switzerland and Brazil. At the end of 2024 they handed it over. Since 2025 the second generation has continued the work under the name Urbanstreet.
What remains is the double perspective. Building a Swiss consulate general in Brazil teaches you that neither language nor building culture nor the path through the authorities can be taken for granted — and that a project fails at exactly those points, not on the design. That experience sits in every feasibility study we calculate today.
Patrick and Sandra Hüppi found their architecture practice on 1 October.
Converted into a stock corporation, later Skyline Development AG.
The subsidiary rd2b limitada is founded in Brazil. The Swiss Consulate General follows, among others.
After almost thirty years Patrick and Sandra Hüppi hand over the leadership.
The second generation continues. Urbanstreet AG is founded in December.

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.

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.

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.
Study for a green vertical city. Density, outdoor space and return are not a contradiction — they simply have to be calculated together early enough.
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.
Your contacts
Two numbers, no queue.
From the first call you speak to the people who will also run your project. Decisions are taken where the project is worked on — not one level above.

Property management
Property management is not a by-product of planning here, but a unit of its own with its own brand. It looks after properties in the portfolio — closing the circle from development through delivery into daily operation.
