Concrete slab for 6x6 double garage

[Dedwards]

Hi all,

 

I'm going to be building a 6x6 concrete block garage with a low pitched roof.

 

As it will be going in the front garden and due to it being over 30sqm i know i will need planning approval.

 

Question is do i also need building regs? And what are they?

 

I was planning on putting it on a concrete slab sat on 100mm of compacted mot type 1. Will this be OK and are there any regs for the slab?

 

Cannot find anything!

 

Thanks peeps

Planning is needed for it because of it's location, not size.

 

Building regs is needed on > 30 square metres, might even be a smaller amount.

You will need Planning Permission but possibly not Building Control Approval..

 

Planning permission for outbuildings (inc garages)..

Quote

Outbuildings are considered to be permitted development, not needing planning permission, subject to the following limits and conditions:

 

* No outbuilding on land forward of a wall forming the principal elevation.

* Outbuildings and garages to be single storey with maximum eaves height of 2.5 metres and maximum overall height of four metres with a dual pitched roof or three metres for any other roof.
* Maximum height of 2.5 metres in the case of a building, enclosure or container within two metres of a boundary of the curtilage of the dwellinghouse.
* No verandas, balconies or raised platforms (a platform must not exceed 0.3 metres in height)
* No more than half the area of land around the "original house"* would be covered by additions or other buildings.
* In National Parks, the Broads, Areas of Outstanding Natural Beauty and World Heritage Sites the maximum area to be covered by buildings, enclosures, containers and pools more than 20 metres from the house to be limited to 10 square metres.
* On designated land* buildings, enclosures, containers and pools at the side of properties will require planning permission.
* Within the curtilage of listed buildings any outbuilding will require planning permission.
 

 

Building Regulations

If the floor area of the building is between 15 square metres and 30 square metres, you will not normally be required to apply for building regulations approval providing that the building contains NO sleeping accommodation and is either at least one metre from any boundary or it is constructed substantially of non-combustible materials.

 

If you are putting in power or lighting that will need Building Control involvement but if you get an electrician to do it they should sort that for yo and  notify Building Control. Offer to do the digging to reduce cost. Typically they would install a "Garage CU" with an RCD and 2 MCB plus an earth rod, sockets and lights.

^^^ But 6 by 6 metres is over 30 square metres so will need building control.

Oops yes. Sorry. Bit distracted. I have my son here trying to ask me questions on subjects I last studied 40 years ago.

Is the rule not internal floor area, so if the internal floor area is kept below 5.4x5.4 you just sneak in below the rules.
