I am currently working on a walled park for a city display. It is on 6x4 of the 32x32 baseplates.
I started out with allowing 4 studs deep LBG tile around the whole park, that will act as the footpath. And then tan brick to form the wall of the park.
I then added some corner turrets, and gold fencing above the brick.
I then added some gates around the 4 entrances to the park.
Here is a close up of the unfinished gate.
Pathways added to the centre
Lampost's to light the pathway at night
I nice tree stump and some flowers
Even some dogs playing in the park
I have added some trees, minfigs and benches
And here is the completed build. I will probably add more details, but for now, it is done.
