Updates in Brief
Up-to-date Specifications for Home Extension, New Build, Flat Conversion, Loft, Basement & Garage Conversion, New Build Flats and Garage Build Plans
The Construction Notes & Specifications form an essential component of a Building Regulations plans submission for Building Control or for an Approved Inspector.
Building Regulations Guidance Notes and Approved Documents are an aid to compiling Construction Notes for drawings but preparing a clear and concise specification for an Application can prove to be an arduous task.
Our categorised pre-prepared Building Regulations Construction Notes can be added within the App with a few clicks of the mouse into a specification that is custom-designed to meet the requirements of your Building Project.
Many of our construction notes are very specific, so please select the correct one for your situation (ie correct dimensions, type of insulation) and type of plans (ie house extensions, loft, flat, garage conversions or garage builds)
This is where our innovative and easy-to-use App for producing Building Regulations Specifications for Home Extension, Loft, Flat, Basement and Garage Conversion, Garage Build and New Build Plans comes into its own, offering more than standard construction guidance.

Withing the many of the Specifications and Detail Drawings on BuildingRegs4Plans, the Approved Documents are referenced. Even where one of the Approved Documents isn't directly referenced, much of the information within the specifications does relate to one or more of them. Since this is the case, it would generally be too cumbersome to explicity mention every Approved Document reference.
In the list of approved documents below, we've provided some references to our specifications in order to demonstrate the relevance of the specifications and drawings. However, the examples provided represent only a tiny proportion of the references made, serving only as small sample.
Our specifications are primarily categorised under project types e.g. House Extensions, Flat Conversions, New Builds etc. Within each of the Build-Types, the specifications are further subcategorised by areas of the build e.g. Externals Walls, Roofs etc.
In some cases, a subcategory is directly related to a particular Approved Document e.g. Part M (Access & Use), Part O (overheating), Part P (Electrical Safety), where a single aspect of a particular Approved Document is the main focus of the specification. However, many of the specifications may relate to several aspects of Building Regulations and multiple Approved Documents, in which case the physical area of the build constitutes the category e.g. External Walls, Internal Works, Floors etc.
When building a specification, in addition to the specifications and drawings related directly to the relevant section, additional specifications may need to be included to provide information on other aspects e.g for a stairway or corridor, it may be necessary to include additional specifications relating to fire and escape routes.

Specifications for Home Extension, New Build, Flat Conversion, Loft, Basement & Garage Conversion, New Build Flats and Garage Build Plans
The Construction Notes & Specifications form an essential component of a Building Regulations Application for Building Control or for an Approved Inspector.
Building Regulations Guidance Notes and Approved Documents are an aid to compiling Construction Notes for drawings but preparing a clear and concise specification for an Application can prove to be an arduous task.
This is where our innovative and easy-to-use App for producing Building Regulations Specifications for Home Extension, Loft, Flat and Garage Conversion, Garage Build and New Build Plans comes into its own, offering more than standard construction guidance.
Here's a screenshot of the Building Regulations Specification App (for house extensions):
Our categorised pre-prepared Building Regulations Construction Notes can be added within the App with a few clicks of the mouse into a specification that is custom-designed to meet the requirements of your Building Project.
Many of our construction notes are very specific, so please select the correct one for your situation (ie correct dimensions, type of insulation) and type of plans (ie house extensions, loft, flat, garage conversions or garage builds), eg

To tryout our Building Regulations Specification App, you can begin straightaway by clicking one of the main category buttons above, House Extensions, Loft Conversions, Flat Conversions, Garage Conversions, New Build or Garage Build. To access the Loft Conversion, Garage Conversion, Flat Conversion, New Build or Garage Build Specifications you'll need to register for an account. But you can see our House Extension specifications on the app (although the 'copy' function has been disabled for non-registered users.)
If you want some help and guidance before getting started please look at our Quick Start Guide or watch the Introductory Quick Start Video. There are also information pages that you should read for New Builds and Flat Conversions as well as an FAQ page.
We believe that Building Regs 4 Plans can take the hard work out of manually creating a Construction specification from Building Regulations Guidance Notes and the Approved Documents.
Lastly, we hope that you enjoy using our website and app!
