Update! According to Scotsman, J. K. Rowling has won planning permission to build the tree houses.

Look what J.K. Rowling is having built for her children!  This is so incredibly awesome, I need to figure out how I can get someone to build one for me!

When the creator of Harry Potter decides to build an adventure playground for her children, you expect something magical.
But even by JK Rowling’s standards the 40ft high, two-storey tree houses planned for the back garden of her Edinburgh mansion are something spectacular.
The Hogwarts-style towers – estimated to cost around £150,000 – are so big that they need planning permission.

Each wooden tree house is to be built on stilts and boasts balconies, carvings and turrets that wouldn’t look out of place in a Potter adventure.
The towers are linked by a rope bridge and can be approached by a secret tunnel hidden underneath a raised wooden walkway.
Plans lodged with the City of Edinburgh Council reveal the houses are intended for Miss Rowling’s two youngest children David, nine, and his sister Mackenzie, seven.

According to the drawings ‘David’s Tree House’ is closest to the secret tunnel and has a specially designed trap door and fireman’s pole escape into the garden
Meanwhile ‘Kenzie’s Tree House’ has its own spiral staircase and a stainless steel playground slide leading to a double set of swings.
A wooden walkway connected to the giant structure leads to a giant trampoline deck that is shielded from public view by a row of extra tall conifers.

There is nothing not cool about this, right?
