About This Service

Accurate Information
for
Existing Buildings

A measured building survey records the existing dimensions, layout and features of a building with precision. It provides the reliable baseline data that design professionals need before making any changes to a structure.

Whether you're planning a refurbishment, extension, conversion or structural alteration, an accurate measured survey ensures your design team is working from correct information — reducing risk, preventing costly errors, and streamlining the planning process.

Our measured building surveys are used for planning applications, interior redesign, feasibility studies, and building regulation submissions across London and the South East.

Benefits

Why Choose a Measured Building Survey?

An accurate measured survey is the foundation of every successful building project.

Accurate Existing Building Records

Get a precise record of the building as it stands — dimensions, layout, levels and features — measured on site by professional surveyors.

Better Design Decisions

Design teams work more efficiently when they have reliable survey data. No guesswork, no assumptions — just accurate information to design from.

Reduced Risk During Refurbishment

Unexpected issues cost time and money. A measured survey identifies the true building condition early, so risks are managed before construction starts.

Useful for Planning and Design

Measured surveys are accepted by local authorities for planning applications and provide the essential base drawings for architectural design work.

Supports Architects and Engineers

Our survey drawings are produced to professional standards and formatted for direct use in CAD software — ready for your design team to work with immediately.

Clear CAD and PDF Deliverables

Receive fully layered CAD drawings and clean PDF outputs — organised, clearly labelled, and delivered in your preferred format and coordinate system.
