A Guide to your Survey

An accurate measured survey of the area in which works are proposed is essential at an early stage. As well as providing the dimensions required in order to prepare designs, the survey also reveals potential problems and opportunities. The earlier such information is known, the easier it is to design out problems and make the most of opportunities.

Pre-application advice

It is often a good idea to meet a planning officer for an informal discussion before you submit an application. Some local planning authorities charge for this service so it’s a good idea to check first. It is also a question you have to answer in the application form and can assist the LPA in dealing with your application.

 

Pre-application advice is encouraged as it can:

 

  • Verify the list of local requirements each planning authority can require.

  • Reduce the likelihood of submitting invalid applications

  • Help you understand how planning policies and other requirements affect your proposals

    If you are meeting a planning of officer you should be fully prepared to describe your proposals and show plans. You can:

  • ask for an assessment of whether there seems a reasonable chance of getting permission;

  • discuss site problems such as roads, footpaths, power cables, watercourses, sewers and telephone lines; and

  • ask about potential problems such as noise and traffic and whether the council might impose conditions to overcome these problems rather than refuse planning permission.

    The level of preparation required depends on what you propose to do. In simple cases it should be sufficient to look at the main issues governing the grant of permission and decide which of these are relevant to your application. Say why you think your proposed development should be allowed to go ahead.

  • Because planning applications will normally be decided in accordance with the development plan you will need to justify any proposals which would constitute an exception to the plan.

Planning

We work with you to develop designs that meet your requirements. Once you are happy with the proposals, we prepare drawings for applications for Planning Permission, Listed Building Consent, and Conservation Area Consent, as required. We also prepare supporting documentation, (including the Design and Access Statement that is often required), complete the application forms on your behalf, and liase with the Local Authority.

 Extensions & Loft Conversions

Building Regulations/ Building Control

We prepare more detailed drawings and information to demonstrate that the design complies with the Building Regulations. We complete the required forms and submit these on your behalf with the drawings.

Energy calculations are often required, and we are able to undertake these for domestic projects.

Class A

1. On designated land extensions of more than one storey are not permitted development.

 

*Designated land includes national parks and the broads, Areas of outstanding natural beauty,conservation areas and world heritage sites.

 

2.Extensions (including previous extensions) and other buildings must not exceed 50% of the totalarea of land around the original house. The term “original house” means the house as it was first built or as it stood on 1st July 1948 (if it was built before that date).Although you may not have built an extension to the house, a previous owner may have done so.

The enlargement, improvment or other alteration of a dwelling house.

Summary:

Two-storey rear extension ( extensions of more than on storey )

*Sheds and other outbuildings must be included when calculating the above 50% limit.

3.Maximum eaves and ridge height of extension no higher than the existing house. If extension is within two meters of a boundary maximum eaves height should be no higher than three meters to be permitted development.

 

 

4.Extensions of more than one storey should must not extend beyond the rear wall of the original house by more than three meters or be within seven meters of any boundary opposite the rear wall of the house.

5.Pitch roof extensions higher than one story to match that of the existing house, as far as is practicable.

 

 

6.Meterials used in exterior work to be similar in appearance to those of the exterior of the existing house.

 

 

7.Any upper-floor window in the wall or roof slope in a side elevation must be obscure-glazed and non-opening unless the parts which can be opened are more than 1.7 meters above the floor of the room in which it is installed.

 

 

8.No balconies or verandas are permitted development .

 

 

 

Class B

The enlargement of a dwelling house consisting of an addition or alteration of to its roof.

Summary:

Loft Conversion (roof extension)

A loft conversion for your house is considered to be permitted development, not requiring an application for planning permission, provided Certain limits and conditions are met.

1. Roof extensions are NOT permitted development for houses on designated land.

 

2. To be permitted development any additional roof space created must not exceed these volume allowances:

 

   *40 cubic metres for terraced houses.

   *50 cubic metres for detached and semi-  detached houses.

 

Bear in mind that any previous roof space additions must be included within this volume allowance. Although you may not have created additional space a previous owner may have done so.

 3. An extension beyond the plane of the existing roof slope of the principle elevation that fronts a highway is NOT permitted development.

 

 4. Materials to be similar in appearance to the existing house.

 

 5. No part of the extension to be higher than the highest part of the existing roof.

 

 6. Verandas, balconies or raised platforms are NOT permitted development.

 

 7. Any side-facing windows must be obscure-glazed and non-opening unless the parts which can be opened are more than 1.7meters above the floor of the room which it is installed.

 

 8. Roof extensions, apart from hip to gable ones, to be set back, as far as is practicable, at least 20cms from the eves.The 20cm distance is measured along the roof plane.

 

 9. Work on a loft may effect bats.You need to consider protected species when planning work of this type. A survey may be needed , and if bats are using the building, a licence may be required.
