Fixed Price Planning Service For Householders and Businesses


 Why choos Plan b Architecture ltd


"After receiving a high quote from another architect, my builder suggested that I use Plan B Architecture instead. The plans for a bathroom/dormer extension were drawn up in less than a week and quickly modified when I changed my ideas. They sorted out the building regulations and the planning application efficiently. They kept me informed of all developments. I would certainly recommend Plan B Architecture and use them again."

-Angela Pryle,Lewisham
