Thanks for your response. I will consider this when getting quotations for sub contractors

Hi All, Its been exciting to read so much detailed stuff on this website. I am planning on a large rear single storey extension which I intend to self manage with separate contractors such as ground works, brick layers, roofers, plumbers, electricians, plasters. I intend to let the contractors buy the material and only manage the interfaces Is their any guide or reference where I can learn on key interfaces so that I can know which trade required when. Thanks in advance for your suggestions.
