Building Control 


Building Regulations are minimum standards for design, construction and alterations. The Building Regulations 2010 cover the construction and extension of buildings and these regulations are supported by Approved Documents. Approved Documents set out detailed practical guidance on compliance with the Regulations. 


The Approved Documents cover thermal performance (U Values), fire safety (wall/door/ceiling construction, no. of floor levels, use class etc), structural (size of lintels, roof timbers, foundation depth/design, wall construction), ventilation (passive e.g. windows & mechanical) etc. 


We can provide a service to produce Building Regulations drawings. The drawings will show sections, 1:50 scale plans and construction detailing in compliance to the Approved Documents. 

We can provide a service to act as your agent and submit U-value calculations (dealing with the application, heat loss and gain of the building), integral details such as door sizes, wall build up, floors etc. 


Please see link for more information on the role of Building Control:


Planning permission should be sought if you are planning to carry out the following works: new buildings, major alterations to existing buildings and significant changes to the use of a building or piece of land. 


There are certain minor building works, known as Permitted Development, which do not need planning permission. There are a number of conditions which need to met in order for the works to be deemed Permitted Development. 


For more information please read the guidance on Planning permission on the link below.


We can provide a service to carry out a measurement survey and produce existing plans, elevations and sections. As part of the package we can produce a set of proposed plans which we will review with the client to produce finalised plans to be submitted as part of the Planning application.
