We had a few "guidelines" to follow with our DEvelopers. Most of us complied apart from my neighbour who has a fully rendered house, black decorative wrought iron on the windows and a sandstone driveway. It sticks out like you know what and most of the neighbourhood isn't happy about it. Lawyers were involved but it didn't get anywhere because it is a "guideline" and apparently cannot be inforced, beats me how a house can be approved by Counil and Developers but is not built according to the approved design

We had -
Roof Pitch
Woodland Grey Colorbond Fencing
No front fences
Mid Grey coloured driveways
Garage setback
Double storey (for our land release)
Colorbond Palette colours for render
Aerials not visible from street - most are (we hung our in our roof space)
Bins behind gates
No tap allowed in front garden
No federation/heritage facades
No mirrored windows
Nice letterboxes - not allowed the plain tin style although some still have these.
No planter boxes in front yard
Clothesline/Utilites behind a fence and not seen from street
20% render to front facade
Facade to have 2 different types of material - brick and render okay
Low profile roof tiles
Facade to be visually interesting.......

Increased ceiling heigh for single storey homes
Porch had a to be certain sqm, can't remember the min. requirement
No carports
No car wrecks out front
No caravans/trailers in view
Cannot build the same house and have same facade within 3 blocks in any direction.
Can't think of anymore at the moment.
We actually like the fact that our Estate had these guidelines in place. Unfortunately for us our neighbour broke alot of them. All the other houses look nice though and seeing as this house is next to me I don't have to look at it.
Some nearby Estates don't have any guideline and you can tell, shocking facade colours, same design built side by side using same colours etc
Another nearby Estate had a release where all windows had to be painted timber with a colorbond roof. Timber windows are expensive and they weren't even allowed to stain them. I just don't get that.
