What Client’s Say

Hi Neil, Spent the afternoon there this afternoon and would like to offer my praise for the fantastic building you have created – having not seen progress for a month or so, the wow factor was huge – a massive well done from me!
Simon, Park Leisure
The new extension has changed how we use our Cornish home, and has released space elsewhere in the house – so the impact is considerable. There is more sunshine, better views and the place feels warmer. We are pleased we managed to work closely with Catchfrench Design, your team and the Contractor, to end up with a scheme that was exactly what we wanted – only more so!
Upper Dobbin House
Just a quick email to say thank you so much for my new extension, I never thought this much space could be made available from such a small extension.
Hi Neil, Just been to site and I love those last changes, it really makes all the difference, thanks for the extra time you have given to this!
Hi Chris I would like to add my thanks to Jeff’s for the extraordinary lengths you and your team went to, to enable us to spend some time at St Pirans after Xmas!
