This is Vincent the House Truck by HouseBox in Southwest England.
It was built for a customer, Imogen, who shared a testimony on the HouseBox website:
I love my truck conversion – there’s so much attention to detail & it’s really tailor made, from the snake tank for my corn snake to the fox door-knocker. I was consulted throughout the whole process & really enjoyed being able to pick out the exact look i wanted, from the hinges to the brass kitchen sink. I’ve never loved living anywhere as much as my House-Box & have had so many compliments on it – a security man at Glastonbury Festival called it the prettiest truck he’d ever seen!
It really is a beautiful build! You can take a video tour to get all the details about the inside and find the builder’s contact information on the last page.
