Double Storey House Extension in Clapham
Proficiency embarked on an ambitious Design & Build house extension project in Clapham for Laura Macara, featuring a comprehensive transformation of her property. This extensive undertaking involved demolishing an outdated rear extension, constructing a new two-storey extension, and completing a full garage conversion. The extension project also included a thorough internal remodel of the house, involving extensive re-plastering, rewiring, and replumbing.
Double Storey Extension
This Clapham home was transformed through a bespoke double-storey extension designed to enhance space, light, and modern family living. Featuring elegant Crittall style doors and a striking French Juliet balcony, the project seamlessly connected the interior with the garden while introducing a refined architectural character throughout the property.
Customer Testimonial
We undertook a big project – demolition of an old extension, double floor extension, garage conversion, internal remodelling and full refurbishment including re-plaster, re-wire and re-plumb. We were complete novices so spoke to 6+ different building firms to get quotes, and Proficiency were the most impressive from the start. Their dedicated contract manager Phil worked with us in detail which is what we wanted, always giving quick responses and never pushing us to just get started and worry about the details later, which is what we experienced with some other firms. Having Phil manage the quoting stage is a real bonus....
Proficiency really care about the final result – they want it to look amazing too, and that really comes across in the detail they go into and the advice they offered as we worked through the project. They are also really great about coming back to sort anything that isn’t quite right – they are not the sort of firm to just do the job and never be in touch again.
