Residential site in Zürich with tenants in place and several competing massing ideas. We verified access, utilities, noise and daylight, cut weak options, and reduced the scheme to two compliant choices—regular blocks or twin towers—with a construction cost model around CHF 117.6 million and key drivers named. The investor received one tested plan: what can be built, what it costs, and the steps and timing to permit and lease in a near-zero-vacancy market.

Historic 13-building estate with slow permits, aging structures and no clear phasing. We advanced the project by building the courtyard infrastructure first—paths, underground lines, soil and trees—for about 5% of the budget, using dry-bolted works that never need to be ripped out. This made the estate feel alive and rentable sooner, kept maintenance simple, and left future building phases flexible and lower-risk.

A practical workplace, not a showpiece: making and logistics on the lower floors, offices and services above. We checked the essentials—access, utilities, daylight, fire—and framed a construction cost of about CHF 63.7 million tightly to the real drivers. The investor gets a simple, low-maintenance scheme and a clear path from study to permit and revenue.

Thirteen well-planned apartments on a simple core, with stacked kitchens and baths, warm timber where you touch and concrete where it works. We verified areas and SIA-416 numbers, then set a realistic project budget of roughly CHF 4'700–5'500 per m² and benchmark rents around CHF 3'000–3'900 per flat per month. The result is a clear decision pack—plans, costs, risks and fixes—so the investor can move to permit and lease-up without guesswork.

A calm apartment block wrapped in winter gardens that act as a second skin. The outer layer is dry-bolted and clip-in, with a simple repeating frame, standard materials, heat pump, PV-ready roof and rainwater for planting. For the investor that means fewer surprises, quick repairs, stable operating costs and quiet, bright flats that hold tenants and support a stronger exit value.

A light, low canopy that shades the beach, makes power and quietly collects rain. Parts are dry-bolted and clip-in, so bays open for repairs while wiring and pipes stay clean inside the frame. From 2'376 m² of PV you get about 475 kWp, roughly 0.7–0.76 GWh a year, while the same area harvests around 2.1–2.4 million litres of rainwater—cool shade and steady utilities for lights, showers and kiosks, paid by the sun.

Existing concrete frame, upgraded into passive, low-maintenance apartments instead of a full new build. We keep the structure for its mass and add sun-facing winter gardens as a dry-bolted outer skin with simple, clip-in connections. Result: durable, easy-to-service homes with lower energy use at about CHF 24.6 million total, typically 18–25% cheaper and a few months faster than new construction.

A new-build feasibility on an empty plot with two efficient cores and 15 m deep open floors, so the scheme can work as offices or convert to housing if rules change. The façade is a dry, exchangeable kit—parts bolt on and off—so cleaning and repairs stay simple while the volume steps can absorb later zoning shifts without tearing into the structure. Budget guide is about EUR 2'340 per m² (around EUR 20 million total), with a clear cost plan that covers both outcomes and less risk if the municipality decides late.

Residential site in an established Zürich neighbourhood focused on courtyards, efficient cores and low-maintenance construction. We verified access, utilities, daylight and planning constraints, removed weak options and set a construction cost estimate of about CHF 66.5 million within ±15% around the real drivers. The investor got a clear view of what can be built, what it costs and the main risks before moving to permit and tender.

We kept the existing slab, cut new column holes and set simple foundations, then used KLH timber panels with exposed concrete for thermal mass and low maintenance. Windows are oak, a folding wall opens the south façade, heating relies on solar gain and a central wood hearth, and a drought-tolerant garden with pool and stone loggias stays easy to care for.

The idea is simple: protect the experience, not replace it. A light roof on slender columns floats above the sand while the beach and paths stay as they are; we checked access, utilities, coastal rules and heritage so only workable moves remain. With an estimated cost of about EUR 4.3 million tied to real drivers, the result is a low-maintenance landmark that feels inevitable, not imposed.

We turned an old townhouse into a buildable plan for eight rental flats, testing structure, access, services, daylight, fire and escape routes and cutting anything that would fail. Construction cost is estimated at about EUR 1.15 million with simple, low-maintenance layouts. The investor received a clear decision pack—plans, areas, cost model and risk list—with a clean path from permit to income.

Old stone, new energy logic: the extension is set for solar gain, using the stone as a heat reservoir so the house can run on solar only. Construction cost is estimated at about EUR 543'000, with access, drainage, ventilation, plumbing, gas and electrics laid out in clear scopes and the landscape adding shade and cooling. Structure is reinforced only where needed, then kept pragmatic and low-maintenance, with site and floor plans, room schedule and system notes ready for direct handoff to builder and permits.

Industrial land turned into a buildable city piece. We fixed the street grid, park network, block sizes and heights and the land-use mix by block, and mapped servicing, access, parking and mobility in clear phases so each step works on its own and avoids rework. Construction cost is estimated at about EUR 1.251 billion (around EUR 229'240 per apartment), with a plan you can price, permit and build, backed by a tight decision pack and a defensible path from study to action.

We kept the existing slab, cut new column holes and set simple foundations, then used KLH timber panels with exposed concrete for thermal mass and low maintenance. Windows are oak, a folding wall opens the south façade, heating relies on solar gain plus a central wood hearth, and the garden is drought-tolerant with a circular concrete pool and stone loggias. Construction cost is estimated at about EUR 652'000, with plans, areas table, cost breakdown and system notes ready for a direct handoff to permits and builder.

Seasonal public room made from the street: road panels are cut, set on steel columns with small footings and lifted into a light deck, so services stay accessible and the street can be turned back if needed. Two clear options were costed—an open mesh-skin garden version at about EUR 890'000 and a glass enclosure version at about EUR 1.3 million—both based on simple totals for 432 m². In each case the investor gets one package: panels, steel columns and footings, lighting, drainage, access and basic design/permits, plus a small contingency.
