what it costs

The Planning system has been in place since 1947, applies to buildings as they were on 1st July 1948 when the act came into effect and to buildings constructed since as built. Town Planning regulations control the development of land and if applicable to your project will either permit or not permit what you propose. Permitted development rules changed in 2008 (Some projects not permitted under the old rules may be permitted now) Interactive house

The Building Regulations are concerned with health/safety/structure and increasingly the reduction of fuel consumption/global warming.

Home remodelling building plans prepared for Building regulation and Town Planning compliance only submitted to the Local Authority for their consideration, for your money you get digital "as built" plans sections elevations of building and curtilage proposed plans sections elevations of building and curtilage, the approved drawings will have sufficient information for any competent builder to execute your home remodelling project without any problems.

"Approximate build" prices are for the average dwelling and are  just that, each project is different in complexity and Bronbuild reserves the right to adjust the price, firm offer will only be given after onsite assessment and viewing approved drawings or Bill of Quantities, prices exclude all utility services from the highway to the dwelling (Not normally an issue with existing buildings).

advantages of having plans prepared first and waiting for the necessary consents

Building Regulations and Town Planning Regulations are complex and continually changing, unauthorised building work is a risky business, by working to accurate approved drawings you are more likely to avoid costly mistakes and the possibility of Local Authority enforcement proceedings.

By staying legal, you avoid the surprise of illegal work coming to light by solicitors/local authority searches, you will have the required approval documents to be included with your home information pack when you try to sell, avoiding unnecessary delays, frustration and possibly a lost sale.

Freedom to shop around for the best price from reputable builders by creating a level playing field which conveys the same information to all.
