We added a kitchen across the back of the house some years ago. Access is from the dining room through a doorway which was created by taking out a window and the wall below it.
This left the dining room a little dark so we're now thinking of widening said ex window by around a metre. Hence the need for a longer lintel.
I'm not sure if this is a d-i-y job - I really don't want a complete double-leaf gable end falling on the dining room table (it's glass!).
Anyone got any views/ideas?
Anyone got any idea of ball park cost if I got the local builder in (Leeds)?
TIA
