Eccentric and surprising house and museum of architect Sir John Soane. Mostly unchanged since his death over 180 years ago, it is full of atmosphere. Also have spotlit, late night openings.  

Some places are better to be left a secret. This one e.g.

The oldest surviving fire station in Peckham, converted and restored by 6a architects, is now an annexe to the South London Gallery.

Let your imagination run wild in this surreal London Park. Crystal Palace is a great place to walk around dinosaurs and get introduced in prehistoric vibes.  Sculptor Benjamin Waterhouse Hawkins was commissioned to make lifesized models of newly discovered dinosaurs back in 1952. They were the first dinosaur sculptures in the world, pre-dating the publication of Charles Darwin's On the Origin of Species. They have been recently remodelled in 2002. Note: family and children friendly over the weekends

The most amazing little shop selling natural, organic preserves by the wonderful Lillie O’Brien (ex St John Bread & Wine pastry chef). Super friendly staff and insane jam doughnuts!
