Loft Conversion

Raising the roof Vs Building up the walls

Anonymous user 09/03/2024 - 2.42 PM

I am looking into loft conversions and unfortunately I am just below the minimum amount needed for regular conversion (2.04m at highest) in a 20 x 20 foot roof space. My only options seems to be building upwards by either raising the roof or adding more bricks. I understand that raising the roof would mean putting it at a steeper pitch, and building up the walls would have the roof at a shallower pitch but you would gain more floor space. What I would like to know is the cost difference between these 2 options. I understand both can be costly. Are there any pros and cons to the two different methods apart from the cost that would make you choose one over the other? Thank you in advance. Edited to say thanks for your answer Gary. I do have an Architect and we are drawing plans which involve raising the roof. He doesn't seem to know much about the cost differences though. Luckily for us, we have a split roof where one is higher than the other so we will only be raising it to match the level of the main roof. Hopefully this won't be an issue with planners.
