Starting with certainty: measured surveys and 3D scanning
Most of our projects begin with a simple question.
Is there a project here at all?
Before design work starts, there is a stage of testing what is needed, what is possible, and what already exists. That last part is often less straightforward than it sounds.
Buildings are rarely as regular or predictable as they appear. Walls are not always straight, levels shift, and details that seem minor at first can have a significant impact once work begins.
Measured surveys have long been part of how we build that understanding. Increasingly, we are also using 3D laser scanning to do this with greater accuracy.
Understanding what is already there
At this early stage, the aim is not to produce drawings for their own sake, but to establish a reliable basis for decision-making.
If we are to answer whether there is a project, and what form it might take, we need to understand the building as it actually is.
We carry out measured surveys and 3D laser scanning in-house. This allows the process of surveying to sit alongside the design thinking, rather than being a separate exercise. It also means that information can be captured and used more quickly, and with a clearer understanding of what is needed for each project.
3D laser scanning allows us to record buildings in detail. It captures millions of points across surfaces, creating a digital model from which accurate drawings can be produced.
This is particularly useful where geometry is irregular, where access is difficult, or where the condition of a structure is uncertain.
A boundary wall in Bourn
At St Helena and St Mary Church in Bourn, we have recently been looking at a partially collapsed boundary wall.
The wall is irregular in form and its condition is difficult to assess through traditional measurement alone. In this case, laser scanning provided an accurate record of its current state, allowing us to understand its geometry and areas of damage more clearly.
This information forms the basis for conversations about repair and reconstruction. It does not determine the outcome, but it ensures that decisions are made with a shared and reliable understanding of the existing condition.
A garage in Great Shelford
A recent survey for a returning client in Great Shelford involved a garage and utility building.
Here, the building is sound, but accurate information is still important. The intention is to explore how the space might be adapted or extended, and that requires a dependable starting point.
Laser scanning allowed us to create an accurate model of the building, providing confidence that any proposals developed from it will fit and work as intended.
Although the context is different, the principle is the same. Understanding the building properly supports better decisions.

A deep retrofit in Milton
This approach has also informed our work on a deep retrofit of a house in Milton.
The project involves the careful upgrading of an existing home using Passivhaus principles, improving fabric performance, airtightness and overall comfort.
As with many retrofit projects, the challenge lies in working with what is already there. Existing construction can be inconsistent, and small variations can have a significant impact when pursuing higher levels of performance.
In this context, accurate survey information becomes particularly important. It allows decisions about insulation, junctions and services to be based on a clear understanding of the building, rather than assumption.
The process is one of learning through careful observation and testing. Having reliable information at the outset supports that process.

What scanning allows
The value of 3D scanning lies in what it makes possible.
It reduces reliance on assumption.
It improves coordination between consultants.
It helps avoid the need for re-measuring later in the process.
Above all, it provides a level of certainty at a stage where uncertainty is often at its highest.
A reliable starting point
Whether we are working with a historic church, a community building or a private home, the early stages of a project depend on good information.
3D laser scanning is one of the tools we use to achieve that. Not in every case, but where it adds value by improving accuracy and reducing risk.
It helps ensure that projects begin with a clear understanding, rather than assumption.
If you are considering a project and would like to better understand what is involved, Dirk would be happy to have an initial conversation.
