About us
High-quality design with pragmatic solutions
Fields of work
Our team has a wide range of experiences with office, commercial, residential, public, and urban structures. Architectural planning requires focus on the surroundings, understanding of its many functions, an eye to the users and insight into the financial feasibility of the project. Integrated and innovative planning is required in all phases of work, from the idea to the implementation. We provide the broad-based expertise and specialized knowledge needed for this.
Building information model
The product model embraces the entire building industry and manages the entire information life cycle of buildings. Unlike a simple 3d model on a computer, the product model contains a lot more information about the building’s materials and characteristics. It is a 3d digital database that tracks all elements that make up a building. This information can include surface area and volume, thermal properties, room descriptions, price, specific product information, window, door and finish schedules, etc. Working from the same product model as the architect, the real estate agent can easily obtain exact room dimensions and area calculations, present perspective views from any vantage and even invite prospects on a virtual tour of the building. Interior designers can begin working during the planning phase on the same product model. After construction is complete, building managers are able to use the comprehensive materials list and integrated 3d partion plan to track building assets and modify spaces.
Objectives
The office is committed to providing high-quality architecture that addresses in a pragmatic way the issues of construction, technology and sustainability. The process is driven by design intent – not a predetermined style – and wants to create solutions that have an intimate contact to function and context, as well as high level of beauty and practicality.
