Impressions for the Restoration of a Listed Building

In a restoration project of our Architectural Heritage Monuments, such as the Listed Buildings, the accurate recording of the existing condition of the structure can be done with extreme accuracy and in a minimum of time through Laser Scanning.

Individual Buildings or Parts of Buildings or Facades of Buildings or even Groups of Buildings together with elements of their surroundings and even Residential Groups, can be classified as Listed Buildings due to their particular morphological and architectural elements as well as due to their historical value even as examples of branded architecture.


The process of scanning the structure yields a numerous cloud of points that describe the building with millimetre precision. For example, the individual elements of a building are thus captured in detail and can be preserved as important historical data. This point cloud is then used to create the accurate 3D model and 2D representations, which are the first step in the design and restoration process.

The detailed visualisation of the existing shell also contributes to a more accurate budgeting of the cost of the works, limiting the cost of additional works that arise unexpectedly in the course of a renovation. Acquiring all the information on the “as-built” condition of the building is then incorporated into the BIM, which will follow the construction throughout its lifetime. The BIM contains information on both the as-built condition and construction intervention and is utilised by architects and engineers prior to renovation, and by the owner with those responsible for the smooth operation and maintenance of the building to this end.

Procedure - Deliverables

Whether it is to collect 3D information in order to facilitate collaboration, or to use quantitative information to calculate and plan the project, Laser Scanning is an essential process to increase the accuracy of the information of a restoration project.In historic buildings where there are no as-built drawings, we are called upon to prepare precision drawings to check the structural adequacy and architectural design as well as to establish a BIM background for the management of the building and the new use of the building.

The process and deliverables are:

  • 3D Laser Scanning of all areas of the listed building
  • 3D Modeling of all the 3D laser scanning of the entire building, including all of the building’s 3D areas
  • 3D reconstruction of the entire building, including the creation of a 3D 3D model of the building
  • Production of floor plans of all levels, sections and elevations, production of elevation topographic plan for the issuance of the building permit for the restoration

Our Projects

Contact us!

Do not hesitate to call us if you want us to be directly in the field to suggest boundaries and measurements.

It is advisable to have someone with you who knows the property boundaries. It will be useful to have with you old topographic maps and anything related to the property (contracts, building permit plans, expropriation plans, classification deeds, cadastral charts, etc.). In case of a large area, wear comfortable clothes and shoes because we will have to walk on the property’s contour to find its boundaries.
