Accurate Floor Plans for Planning, Renovation & Property Conversion

​

Whether you're renovating, extending, or converting a house to flats, it all begins with one essential step: an accurate measured building survey.

​

At Draw Plans, we produce clear, reliable measured survey plans from just £695 + VAT, serving homeowners, developers, and professionals across London and the Home Counties.

​

Our architectural designers capture precise internal and external measurements to produce to-scale floor plans ready for planning applications, design work, or building control submissions.

​

What is a Measured Building Survey?

A measured building survey is a detailed drawing of an existing building, created from a physical site visit using laser equipment and measurement tools. These plans include:

• Floor plans

• Elevations

• Sections

• Roof plans (if required)

​

They show accurate positions of walls, windows, doors, staircases, and more — forming the foundation for any future architectural work.

​

Why You Need a Measured Survey

Measured surveys are essential if you are:

• Planning an extension or loft conversion

• Converting a house into flats

• Obtaining planning permission

• Creating HMO licence drawings

• Selling or leasing commercial property

• Recording existing conditions before construction

​

Without an accurate measured survey, errors in your building works are more likely, which could result in planning rejections, increased costs, or construction delays.

​

What’s Included in a Measured Building Survey?

At Draw Plans, our standard measured survey includes:

• Full internal site measurement

• Existing floor plans for each level

• Wall thickness and ceiling heights

• Window and door positions

• Staircase configuration

• Structural features (beams, columns, chimney breasts)

• External walls and property outline

​

Optional add-ons include:

• Roof plans

• Internal elevations

• External elevations

• Sections through the property

​

All drawings are provided as editable PDFs and CAD files.

Tips for Getting the Most from a Measured Building Survey

Here’s how to make your survey as accurate and useful as possible:

​

Clear Access

Ensure all rooms, storage areas, and lofts are accessible on the survey day.

​

Utility and Plant Info

Have details ready for boiler locations, electrical panels, meters, and major appliances.

​

Plan Your Goals

Let us know if you’re planning a garage conversion, loft conversion, or flat conversion — we’ll tailor the detail accordingly.

​

Ask for Add-Ons

Want elevation or section drawings? It’s best to capture that during the initial visit to save time and cost later.

​

How Long Does a Measured Survey Take?

Most site visits take 1 to 3 hours, depending on the size of the property. Draft drawings are usually delivered within 3–5 working days.

​

We can often accommodate faster turnaround times if required for urgent planning or legal submissions.
