Ground Floor Maisonette Measured Survey & Existing Drawings – Wandsworth
Wandsworth, South West London

Results at a Glance

Confirmed scope for the ground floor maisonette only, avoiding unnecessary survey coverage.

Captured drainage-related features required for a wrap-around extension design.

Issued a draft drawing pack for review before finalising.

Delivered final CAD and PDF drawing set with supporting site photographs.

The Challenge

The client needed a measured survey and existing drawings for a ground floor maisonette in Wandsworth to support a single-storey wrap-around extension scheme, with drainage information treated as a priority. Early in the brief, we clarified the survey extent because the address presented as more than one unit, and the client confirmed only the ground floor maisonette was required.

The survey also needed to account for drainage-related items typically required at early design stage (such as SVP locations, manholes, and drain runs where visible). During the site visit, our surveyor noted there was no visible manhole in the front or rear gardens, which was recorded for the project file and reflected in the documentation.

Our Solution

We coordinated access and attendance details ahead of the appointment and carried out the on-site measured survey as scheduled. The scope focused on producing reliable base information for design development, including the areas relevant to the proposed wrap-around extension, and noting any visible drainage features that could influence layout and connection assumptions.

Following the site visit, we produced a draft drawings pack and shared it for review. After confirmation, we issued the final drawing set as both CAD (DWG) and PDF files, alongside the site photographs, so the client team could progress with design, coordination, and onward approvals as required.

What We Delivered

Measured existing floor plan (ground floor maisonette)

Roof plan (as part of the existing drawing set)

Existing elevations (front and rear)

One existing section

Drainage-related annotations where visible/confirmable (e.g., SVP locations; manhole visibility noted)

Draft drawings pack for review prior to final issue

Final CAD drawing files (DWG)

Outputs Delivered

DWG

PDF

The Process

Agreeing Scope, Fee and Friday Access

We confirmed the required outputs and clarified the extent of the property to be surveyed, as the address appeared to include more than one unit. The client confirmed the scope was the ground floor maisonette only, with drainage-related information treated as important for the extension design work.

On-Site Survey

We agreed an attendance window and shared surveyor contact details to streamline access on the day. We also requested the on-site contact information so any last-minute coordination could be handled quickly, ensuring the visit proceeded smoothly within the agreed timeframe.

Cross-Checking Before Leaving

Our surveyor completed the measured survey on site, capturing the information required for producing existing drawings. Drainage-related items were checked where possible; during the visit we recorded that there was no visible manhole in the front or rear gardens.

Turning Survey into Plans and Elevations

We converted survey data into a structured set of existing drawings and issued a draft drawing pack for review. This allowed the client team to verify key elements and confirm the drawing set met the needs of the wrap-around extension project before final release.

Draft Review and Final Handover

Following review, we issued the final outputs as CAD (DWG) and PDF drawings, along with the associated site photographs. This ensured the client team had a consistent, survey-based base set ready for onward design coordination and any required submissions.

Results & Impact

The project concluded with a complete existing-drawings package for the ground floor maisonette in Wandsworth, tailored to support a wrap-around extension design. Key scope decisions were confirmed early, drainage-related constraints were recorded (including the absence of visible manholes in the gardens), and the final DWG/PDF outputs plus photographs were issued for the client team’s next steps.
