DISCOUNT PLANS LTD

No, you cannot merge and build from two separate planning applications. 

 

The council would have received separate applications and reviewed each one individually based on the current house arrangement. They would not be aware of how the second proposal would interlock or join with the other.

 

If you require both proposals to build from, you will need to apply in the following format:

 

1. Apply for the first design. Get the approval.

2. Apply for the second design showing the proposed first design (point 1. above) AS EXISTING, shown shaded in light grey with reference to the previous reference application number. The new proposal will then show how it is joined, merged or interlocked by walls and roof structure to the new existing visual. 

Following the above method, the council will understand the overall concept of design, although it has not been built, and will visually see the proposal on how it would be and the layout displayed to see if there will be any impact on external character or harm on the surrounding properties following the normal protocols each case officer goes through when reviewing applications. 

 

If and when the second design is approved, then the merge of both designs is needed for building control, Thames Water build-over agreements, and structural engineering design so that a final building regulation and structural package is created for the building to take place. 

 

It’s as simple as that.......

 

Thinking outside the box?

 

Don’t assume that one design can be considered ok to build from under permitted development as there will be no justification on when that part of the PD design has been completed. This means that the second proposal could be seen by others as being incorporated with the initial PD design, leading to an unlawful development not just on the first build design but on both. A typical example is when building a loft conversion, such as a hip-to-gable design and a double side or rear extension, in two stages but in one build duration. The permitted volume allowance on the loft conversion element is set to 50 SQM3 on a Semi-detached property. When the shell of the dormer is up and the build kicks in for the double when constructing the roof of the double, this could be added to the 50 of the loft as the build is being seen as one development leading to an unlawful loft or vice versa with the whole development. We understand the logic, but the planners can interpret the scope of works from different perspectives.
