Building a Raised balcony Deck with Ground level decking below - Dorking, Surrey.

Interesting decking project that required Planning permission AND building regulations control.

 

There are many different interpretations with different local authorities as to what type of deck requires planning permission. Aspect taken into consideration include, the height of the deck, the volume of the deck structure and the rights to privacy to neighbouring properties. Some local authorities have a very relaxed - modern - attitude to deck structures. Others do not! The main consideration for this particular deck, was that - together with other recent building works - it exceeded the 'volume' allowance for 'extensions'.

How we got to this stage! - See below   
 


Building regulations were required for this project. The fact that it was to be constructed at first floor level, involved structural and safety issues that had to fall within the scope of the Building regulations as described in the document K2.  This document/recommendations, lays down criteria for the height of balustrade hand rails, the gaps between spindles, and also the pitch and general construction of the staircase. There is also a construction issue, in that timbers must conform to various standards normally found in British Standards. Foundation holes also fell within the remit of the Building Inspectors - to ensure adequate support for the structure. There were no building regulations control required for the lower deck.

Planning permission was also required, for the simple reason that the balcony deck exceeded the volume allowance whereby planning permission is waived. (Other extension works had eaten into the 'allowance)

 The project prior to our starting Day 1 ground clearance ready for substantial foundation for support posts for the raised deck section  Holes dug through concrete in order to reach the base sub-soil down at 900mm! These two holes for the main support posts for rasised deck.

 12 bags of concrete were required for each hole in order to satisfy the building control regulations in this case
