The right attic conversion depends on your roof shape, but every option still works out far cheaper than moving house.
Side dormer conversions suit hipped roofs, creating the headroom needed for a staircase and a larger, more usable room. Hip-to-gable conversions go a step further, replacing a sloped hip roof with a full vertical gable wall for the biggest space gain of any option. Both often start from around €40,000, which is still less than the stamp duty, solicitor fees and estate agent commission that come with a typical Dublin sale.
Whichever roof type you're working with, the case for converting over moving still holds up:
