What Aylesbury homeowners tell us.
"A 7m bifold set across the back of our Chiltern barn conversion. Faultless install, faultless finish. The traffic door is a small detail that we now use every day."
"Their surveyor drove out twice before we'd even signed anything. That's the level of care we hoped for and rarely find."
"Insulated garden studio, fully wired, plastered and finished — six weeks from survey to keys. It reads as an extension of the house, not a shed."
