Loft Conversions Question

Can i replace and raise this support beam?

Ok we have converted the 2nd floor of a coach house. Problem is the support beams are too low, see: http://i1204.photobucket.com/albums/bb419/phoenixbrighton/beam.jpg

Can we replace and raise these beams so we dont walk into them?
What do we need to do/buy?
Expensive?

Thanks everyone!

Yes you usually can raise collar beams.To really get it right, get a structural surveyor to give you a job specification. i.e. timber/steel to replace existing collar beam.Although a competent carpenter will be able to provide advice or solution to this, it will hold no water if a subsequent buyer picks up on this and wants to see building control paperwork. It will cost about 150.00- 250.00 to get this but I would advise
it.
Sorry I cannot assess job cost without seeing it .

You can raise collars, but I don't think that you will gain enough height with this truss before the tie stops carrying out its job (of lateral restrait). Do not get any builder/ carpenter to offer any quotes on carrying out work until a structural engineer has been contacted (as they will be a waste of time/ inaccurate).

The 'A frame truss' is a major structural element to the whole roof. First port of call is to get a structural engineer to come up with a scheme. From there you can have quotes provided. You will also need building regulations approval to validate all works carried out.

Define 'expensive', but yes it will cost alot of money to carry out correctly. £1000's

I carry out structural calculations for this sort of work. It isnt too expensive but you have peace of mind to know it has been designed properly.
