Rooflight Loft Conversion

[AJC]

Hello

 

I'd like to make better use of the loft space in a semidetached 4 bedroom house, built 1906. Objectives are to:

 

1. Create a better insulated "warm loft" space

2. Improve access with larger loft hatch and e.g. foldable loft ladder

3. Velux windows

4. Remain within existing roofline with no plans for dormer extension 

5. Include built in storage/cabinetry and overall result to resemble something like the screen shot below. 

6. Would be used for storage and perhaps as a hobby/exercise space, to house an exercise bike and rowing machine etc. 

 

We don't want to pursue a formal dormer loft conversion, as feel the expense will not add sufficient value to the house. We're also likely to move within next 5 years. I'm aware that this means the space will not be considered habitable and could not be considered an extra bedroom etc. 

 

Initial advice conflicts and I'd be grateful for guidance. A reputable structural engineer advises that for a modest loft conversion such as this timber reinforcement of existing ceiling joists is sufficient. Subsequently, any builder I ask to quote advises that formal input from an architect & structural engineer is necessary. 

 

Grateful for any advice!

 

Thanks, 

Anthony
