Help with R Codes R40 2000m

Hi,

Newbie question,

I am trying to understand what can be developed on 2000m of R40 for a unit site. I understand 45% of land is to be open leaving 1100m but what is the min unit size and thus ie range of possible units or do other restrictions clip this further Do car ports reduce your calculation or is there a get around.

Appreciate members help.

 

@db444

2000/average site area ( 220sqm)= 9 lots. Some can be as small as the minimum lot area of 180sqm. And there is a 5% variation that can be applied for.

Councils may have requirements in their tps (town planning scheme) as to requirements to get R40 ie build double story, minimum frontage etc etc

Or for multi dwellings (apartments) use plot ratio of 0.6 so 2000x.6= 1200sqm of build area so for example 17x 70sqm apartments.

Generally anything open on two or more sides doesnt count as build area and instead open space so carport alfresco portico etc.

Hope that helps.

 

that does help, thanks for the quick response. So does the second floor count as floor area since the footprint does not increase?

 

In regards to open space- No. It uses the footprint which would be around 55% of site area . And open space 45%.

 

9 lots may need some wide driveways or private roads

 

This is true. I have heard changes are coming out of WAPC (or are they gazetted yet?). Not sure where they went with this but I heard the access could be much wider?

 

Second floor is counted for apartments/multi units but not for grouped dwellings (villas/townhouses)

 

This is actually a reasonably complex question. For development, you will want to check out the R-Codes, particularly the definitions and also the explanatory guidelines. You will be particularly interested in the definition of Open Space. This is the bit about carports you will be interested in:

That would seem to indicate that carport is not open space. But, anything in bold is further defined, so we would need to work through those definitions to make sure we are on the right track.

Hey @HD_ACE, I seem to recall in a previous version of the R-Codes that carports were included in open space?

@Perthguy

I think The part in the r-codes to look at is

• verandahs, patios or other such roofed structures not more than 0.5m above natural ground level, unenclosed on at least two sides, and covering no more than 10 per cent of the site area or 50m2 whichever is the lesser;

But i agree that the clause

• covered car parking spaces and covered walkways, areas for rubbish disposal, stores, outbuildings or plant rooms.

Does make you wonder. So now im not to sure lol
Hard to read the r-codes on a phone

 

I have a feeling a covered car parking bay is different to a carport. But I'm not sure.

@Aaron Sice has been teaching Rcodes today so he can probably illuminate.

 

Hmm... yes. If someone said covered car parking bay, I would not immediately think "carport", so it certainly raises some questions. To complicate things further, the definition of "Open space" does not have carport in the "includes" or the "but excludes" sections. It only refers to "uncovered car parking spaces" and "covered car parking spaces". At a guess I would say that "covered car parking spaces" would include carports and garages. However, it is not safe to guess when dealing with the R-Codes.

 

Carport

Carport A roofed structure designed to accommodate one or more motor vehicles unenclosed except to the extent that it abuts a dwelling or a property boundary on one side, and being without a door unless that door is visually permeable.

 

Any covered parking space for a vehicle is excluded from open space.

Uncovered spaces are expressly written as being included as open space.

Define 'covered' with Google and you will find a carport and/or garage meets this definition.

Now, if it were using the term 'enclosed' carbay like it used to.....

 

Thanks @HD_ACE and @Aaron Sice. I thought these days that carports were excluded from open space.

 

Yes that's what I'm saying
