Surveys and existing information
Before any design, planning, or technical work can begin, it is essential to understand what already exists. Surveys and existing information provide the factual base from which all decisions are made.
At HOBBS ARC, we treat this stage as the foundation of the entire project, because inaccurate information at the outset almost always leads to delays, redesigns, and additional cost later on.
Why surveys matter
Assumptions are one of the biggest risks in residential projects. Properties often differ from historic drawings, estate agent plans, or what appears obvious on site.
A proper survey ensures:
-
Designs are based on accurate dimensions
-
Planning and technical drawings align with reality
-
Structural risks are identified early
-
Contractors can price works confidently
In short, good information prevents bad surprises.
Measured building surveys
A measured building survey records the property as it actually exists.
This typically includes:
-
Existing floor plans
-
Elevations
-
Sections (where required)
-
Key levels and heights
Surveys are carried out using laser measurement equipment to ensure accuracy, particularly where buildings are irregular, altered, or extended over time.

Site and context information
Beyond the building itself, understanding the site and its context is equally important.
This may include:
-
Boundary positions and constraints
-
Relationship to neighbouring properties
-
Levels across the site
-
Existing access and services
This information is critical when assessing development potential, neighbour impact, and compliance with planning and building regulations.
Existing drawings and historic information
Clients often provide historic drawings or previous approval documents. While these can be useful as reference material, they should rarely be relied upon in isolation.
We review and verify existing information to confirm:
-
What remains accurate
-
What has changed over time
-
What must be re-measured or updated
Where appropriate, this information is integrated into a current, verified survey set.
Surveys as a risk-management tool
Accurate surveys are not just a design requirement, they are a form of risk control.
They help to:
-
Reduce planning objections
-
Avoid redesign during technical stages
-
Minimise on-site variations
-
Protect budgets and programmes
For complex or older properties, this stage is especially important.
A solid start leads to smoother projects
Every successful project starts with clear, reliable information. Whether the aim is a modest alteration or a major redevelopment, surveys ensure the design process begins on solid ground.
At HOBBS ARC, we see surveys and existing information as the quiet discipline that enables confident design, smooth approvals, and controlled construction.
