Hi Stripyshirt,
I work as a Project Manager for a design and build company in SW London and I have recently worked on a project like that in SW6, although we were only allowed to go 2/3 of the bedroom below. It actually worked out to be a really lovely space and a much needed additional bedroom for a brand new baby boy.
It was one of the smallest jobs we took on (we did design, planning and build), but nevertheless the clients were very happy with the results and it actually worked out financially for them, as the additional bedroom in the area is worth more than the overall cost of works.
I’m happy to advise on any questions you might have and if you’d like to speak to our Design or Pricing team within my company, feel free to drop me a message and I will put you in touch with the right people.
Kind regards,
Karolina
