Promotion Plein-Sud – 4 Contemporary High-End Villas — Thônex
House · New developmentGeographical Location Situated in a residential neighborhood of the Thônex municipality, the project to build 4 villas is ideally located. Sheltered from all nuisances and yet very close to all urban amenities, the situation offers an ideal living environment for the whole family. This location at the edge of the built-up area benefits from the valuable advantages of the left bank of Geneva. While being close to schools, shops, public transportation, and numerous sports facilities of the municipality, it is at the gates of the lush and rich Geneva countryside. The existing plot The privileged geographical context of the plot must be emphasized. In addition to its remarkable situation, the place is conducive to well-being. Indeed, it benefits from absolute calm and is ideally oriented North-South for a housing project. As the name of the road indicates, the plot enjoys "full south" sunlight. The project translates this situation into a story of light. The project Unique project of four contemporary, family-oriented villas with high energy performance (HPE), designed by architects to fully benefit from a "full south" orientation. The project consists of 2 buildings oriented East-West, thus benefiting from large openings on the South. The natural benefits of the sun are exploited optimally. Each building is itself composed of 2 semi-detached villas. This layout maximizes the interior/exterior relationship of each villa. They benefit from a L-shaped garden in direct contact with the interior spaces. Special attention has been paid to improving privacy between neighbors. The North façades are therefore intentionally designed without openings. Ensuring a certain privacy, this architectural choice also follows a thermal comfort logic. The volumetry of the project is based on this reflection. The floor volume is divided into two separate parts, thus allowing for south-facing daylight intake in each bedroom and creating a skylight along the entire length. The separation of the floor volumes contributes to a light reading of the object. The visual mass is also reduced by the traditional shape of the volumes. Balconies are deliberately placed at the ends also with this in mind. The offset of the floor volumes ensures a covered entrance on the North and contributes to solar protection on the South façade. The composition of these elements highlights the architects' desire for a modern reinterpretation of the villa. The human scale is thus placed at the center of the reflections. The Configuration Ground floor: - Entry space with wardrobe and guest WC - Kitchen (with the possibility to close/open to the living area) - Living space in direct relation to the garden composed of the living room and dining room - Terrace - Detached covered parking for 2 vehicles - A common storage for waste management. First floor: -1 "Master Suite" volume with bedroom, dressing room, and bathroom -1 "children" volume composed of 2 bedrooms and a bathroom Basement: - Laundry room - Cellar/workshop space (open to a patio) - Playroom space (open to a large patio) which can be converted into an independent bedroom with bathroom.

Frequently asked questions about buying a new development
How does buying off-plan work in Geneva?
The purchase is generally made through a forward sale with instalments paid as construction progresses, governed by a notarial deed. Rousseau 5 supports you from reserving the unit through to the handover of keys.
What are the purchase costs on a new development?
When buying off-plan, transfer duties are generally calculated on the land value at the time of signature — a significant advantage over an existing property. The Casatax scheme may apply, depending on the price and the intended use of the home.
Can the finishes be customised?
Yes, depending on how far construction has progressed: surfaces, kitchens, bathrooms and sometimes partitions. The earlier you reserve, the wider the scope for customisation — which is the point of registering for previews.
What guarantees protect a buyer of a new development in Switzerland?
Buying off-plan in Geneva comes with solid guarantees: a performance guarantee under SIA standard 118, a defects guarantee after completion, and instalments protected by the notarial forward-sale deed. Rousseau 5 goes through the construction specification and the developer's insurance with you before any reservation.
How do you finance an off-plan purchase — mortgage and equity?
Financing a new development in Geneva follows Swiss mortgage rules: a minimum of 20% equity (half of it outside the second pillar) and total charges of around a third of income. Banks offer forward mortgages to lock in a rate before completion. Our mortgage calculator gives you a first reading in thirty seconds.
How long between reservation and handover?
Generally between twelve and twenty-four months from reserving a unit to completion, depending on how far the planning permission and the works have progressed. Buying early — as soon as marketing opens, or at preview stage — gives the best choice of units and the widest scope to customise the finishes.
