Whilst on a trip to Wales recently I was taken to this amazing oak tree by a young girl. She told me that an oak tree with two trunks was actually a fairy doorway, wow!. I like to learn something new every day, though my skeptical mind made me question the validity of her claim!
My variation of the fairy doorway is this link frame just completed with Verve Architects of Cambridge.
It was really hard to get a picture showing the whole frame as is compressed into a tight corner. The design was quite a challenge, given there are two 45° corners, with curved rafters to match the new extension.
