Immo Vea – Your Reliable Partner for All Building and Living Immo Vea supports construction projects from the initial idea to the handover of the keys – and beyond. Based in Wohlen and operating throughout Switzerland, the company supports developers, investors, and owners with expertise, experience, and vision. Starting a construction project often begins with many questions. Immo Vea offers in-depth construction consulting that creates space for clarity. Whether it concerns initial assessments of feasibility, budgets, timelines, or potential challenges – clients receive an honest and understandable assessment. In project planning and execution planning, Immo Vea develops well-thought-out concepts that balance architectural quality, functional requirements, and economic aspects. The goal is always a building that meets the needs of its future users – durable, efficient, and consistent within its context. Immo Vea also initiates projects in the development and construction of buildings – whether new construction, renovation, or the densification of existing properties. This involves not just constructing a building, but creating sustainable living and working spaces. Another important component is tendering and construction management. Immo Vea ensures transparent tendering procedures and reliable coordination on the construction site. Deadlines, quality, and costs are continuously monitored – to ensure the construction project stays within the planned framework and its implementation runs smoothly. In addition to the realization of construction projects, Immo Vea also sells properties – from individual apartments to entire developments. The focus is not only on figures and square meters, but also on personal advice and fair support until the transfer of ownership. The range of services is rounded out by property management. Here, Immo Vea oversees the smooth operation of residential and commercial properties, handles administrative tasks, ensures value retention, and serves as a contact person for owners and tenants. Working with Immo Vea means meeting a team that takes its time, listens carefully, and brings projects to fruition with a steady hand and expertise.
