Hello Compton Terrace Gardens are actually gardens, they happen to be used like a park. That's why they are called and signed as gardens. Originally they were for the private use of people living in the terrace's, please see :- http://www.londongardensonline.org.uk/gardens-online-record.asp?ID=ISL023

Adjustments to area, add/amend service and foot access, remove unnecessary tags, remove POI

No problem, need any help just ask!

I don't think there is a footpath goes through the houses just there.

All change-sets to and including this one are reverted to remove fiction.

Not the proper place to do testing (testing can be done without uploading fiction to the live database). Can I help you with mapping anything.
Your addition has been removed.

Your silly fiction has been removed. If you need help adding genuine features to OSM please just ask.

Removed residential area as it was mapped inside of a residential area, duplication.

Removed paths drawn over established housing.

I have reverted these silly changes.
You show you have a good idea how to map map properly, this is the best map in the world please don't spoil it. And we would welcome some real additions to help us and your good self

It's an informal path through the woods not a of the status you tagged it. The house is not a park. The gardens are not a park. Tagging reversed/removed.

This is actually a service road maintained by the council. Giving vehicle access to properties along it as well as access on foot.

Hello and Welcome to OpenStreetMap.
This footway is already mapped in that the existing cycleway is designated as segregated foot and cycle use. So I have removed the duplication.

Supporting chilly's decision and calm response.

Removed fictional park placed atop existing buildings and private parking area.

Removed fictional park placed atop existing buildings.

Adding made up places is not very helpful to a live worldwide database. Your changes are reverted.
Even so Welcome to OpenStreetMap and if I can help you make a positive contribution please just ask.

With respect I think you will find that under the tree cover is a large area of water. If you haven't actually been there then please look at other maps and aerial imagery.
