The Scenario House | BIM collaboration Case Study on a domestic renovation and extension project in London

Throughout the last decade, the firm has continually implemented and optimised BIM processes, which are typically used on large projects by larger firms, to operate smoothly and effectively within their small-medium-sized firm, as well as on traditional residential projects.

Maya Carni and Ran Ankory bought a Victorian terraced house to fully renovate, extend, and adapt it to their own family’s scenarios. Working on the director’s own home provided an opportunity to fully use Archicad, Scenario’s preferred BIM method, and to see how successful a BIM partnership can be when applied to a single residential renovation and expansion project.

For them, at least for the time being, effective BIM collaboration simply means that the entire project team operates from a single, organised, and regularly updated 3D model from which all project data, drawings, and specifications are obtained.

They start each project by commissioning a precise laser scan survey, from which point cloud data is produced. Using the surveying company’s 2D CAD plans and elevations, they create a 3D BIM model of the current situation in Archicad from scratch.They overlay the point cloud data onto their model as a guide, comparing it to their model and ensuring that it is correct while still being easy.

Another feature of their practical approach to BIM is that their experience has shown that internal BIM collaboration within their firm is just as crucial as collaboration with other consultants. They use Archicad Teamwork to work on the same design project at the same time, which ensures that different team members will work on the same concept at the same time without colliding.

Each project is assigned a design architect and a technical architect, who can collaborate seamlessly using Teamwork. The idea is that they will continue to develop and refine their template from project to project. As each project poses new challenges and necessitates innovative solutions, their in-house BIM expertise grows.

The Scenario House project’s key design challenge was to physically and visually link the front part of the house with the basement below, while creating an open plan that included living, dining, and kitchen.

This challenge was presented to Archicad in the form of a detailed BIM model of the current structure, as well as information about the surrounding area and proper orientation. The problem was then completely solved in the 3D setting by constructing a split-level double reception connected to the kitchen and garden beyond via an angled and glazed roof light, as well as a ‘floating’ library feature that leads up to the bedroom floors.

Archicad effectively simulates the real physical building while still integrating data for all design elements. Views, plans, and parts are generated and changed automatically as the model changes.Working with a simulated yet accurate representation of truth inevitably raises the degree of sophistication in design geometry, which architects can easily handle. It aided them in developing and designing a split-floor, open, double reception linked to the kitchen and garden level by an angled, glazed roof extension and a ‘floating’ library feature leading up to the bed in this project.
