1 Day Survey & 3 Days Drafting


Esher, London, United Kingdom

The Project Brief

THS Concepts undertook the project for L+Architects who are a multinational architecture company with offices in London, Exeter and Spain. They are well known for their exquisite designs and attention to detail.

Having been recently purchased, THS Concepts were commissioned by an L+Architects to undertake a full measured survey of one of the spectacular properties within the estate. This was so that the new owner could reinstate the home to its former glory with a much-needed renovation.

The measured survey work involved a precision survey of the property and then producing a range of CAD drawings.

For our client to propose a design scheme, we were contracted to CAD drawings showing:

  • Floor plans
  • Elevations
  • Sections

Our Approach

This measured survey was completed using a Leica TS15 total station and handheld Leica Disto laser measurer. The combination of the instrument data and handheld notes allowed for an accurate but efficient site visit, which was particularly important to our client who required a high level of precision to assist their interior refit.
The existing interior fit out featured the original maple wood panelling and exposed brickwork, with a heavy focus on the lake views via large floor to ceiling windows. It was critical that our survey drawings distinguished between the exposed structural walls and the decorative panels in order to provide our client with an accurate representation of what could and couldn’t be altered.

Starting centrally, where the main feature stairs and skylight are located, a total station we used to pick up key wall lines to ensure any slight angular discrepancies were illustrated. This information was accompanied by hand measurements of items such as door widths, balustrade details and any areas which could be referenced back to an observed wall line. When undertaking a measured survey, we balance accuracy with efficiency, and this will decide on which equipment is suitable, whether that be a total station, 3D scanner, laser disto or a good old-fashioned measuring tape.

It was a large house and a long day, not to mention in the heat of high summer! However, as scheduled, we were able to complete the survey in a single visit as promised to our clients.

Because a total station was used, the drafting process was relatively straight forward, as the key wall lines were pre-determined using coding and line work within the instrument. Our drawings included aesthetic details such as hatching to illustrate the materiality of the design, and the section drawings were produced to include as much detail as possible using survey data obtained from the small loft spaces in the building.


L+Architects used our measured survey CAD drawings to produce their design proposals.

It was a pleasure to experience this inspirational design and based on our client’s proposals we believe this will once again become a piece of awe-inspiring architecture befitting of its beautiful surroundings. We often undertake projects in buildings and locations that are in a poor condition. This project was great to work on due to the existing condition and location of the property.
