From Our Clients

We value our clients and pride ourselves on our relaxed, personal and friendly service. You can hear what it’s like to work with us in the words of some of our clients below.

“I recently commissioned The Structure Studio to carry out some design, planning and structural calculation work for me for a rear and side extension to my 200 year old cottage which included the conversion of a small attached barn into a separate one bedroom studio apartment.

I consulted directly with the Director Gervaise Turbervill who met me on site at the beginning of the planning process and also on two occasions during the building process. Gervaise was very sympathetic to the age of my property and produced appropriate designs and subsequent plans incorporating local building materials.

The build has progressed smoothly, on occasion I have sought some further advice on options for alternatives to lintel structures, in the name of aesthetics, during the building I contacted Gervaise by email and he was very responsive in replying in a timely fashion and with some further advice and discussion.

Building Control and Building Inspectors meetings have gone smoothly without any required alterations to the designs or specifications of building regulations.

Overall, the services provided by The Structure Studio have been very satisfactory and resulted in a smooth planning and building process. Gervaise was very pleasant to work with and happy to incorporate my own ideas while guiding me successfully within the constraints of planning and building regulations.

I would definitely call on The Structure Studio for any further or subsequent design and planning work I require.”

Production of Planning Drawings and Structural Design, Phillip - Leicestershire

“The Structure Studio have been working on the design and engineering of a ground and lower-ground floor extension to my Grade II listed Victorian home in a conservation area since June 2020. The team, led by Gervaise, have developed the drawings from planning stage to Tender. They have carefully considered the effects of the new works on the existing historic structures and clearly explained the design decisions in relation to the structure, aesthetics and heritage.  They have also advised on and successfully obtained a party-wall decision exactly in line with my requirements. As the scope of the work has developed they have advised me on the need to prepare a revised application for Listed Building Consent, and are now also preparing a heritage statement for me.

The Structure Studio, and Gervaise in particular, is responsive and ‘can-do’.  He works efficiently and addresses the issues in a pragmatic way. Importantly he takes the time to explain issues clearly, always recommends a course of action and is a pleasure to work with.

I am very satisfied with their work and would be happy to recommend them to others.”

Basement extension design, Tom - London

Gervaise and his colleague, Oli responded quickly and provided a competitive quote for a structural condition survey. They visited the property promptly and spent a fair amount of time providing additional useful advice on measures required to rectify some of the problems with my building. They acted professionally and their report was very well presented. I would highly recommend The Structure Studio.”
