I'd encourage anyone to use Betta Buildings if they are considering an outdoor office or studio. Roger and his team are so professional, courteous, and they really do absolutely everything to completely finish the job.
They don't leave until everything is perfect- all the lighting is installed, the heater, all the painting is done, etc. This complete package is what we appreciated most. Apart from us finding an electrician to lay the main electricity and phone line to the building, Betta Buildings did everything else. I highly recommend!
