The first thing a professional will look at is the height. Measure the house width internally and the height from the ceiling joists' top to the ridge's underside, then use the sliders to see how much floor space is usable.
The drawing takes 25 cm off the height for a new floor and insulation, and treats the roof as a plain pitched one. Chimney breasts, purlins and the roof shape change the real figures, so a specialist measures on site. The person is 1.75 m tall.
The shape of the roof decides the options. This shows what is common on each type of house, as a guide and not a promise.

| House | Rooflights | Rear dormer | Hip-to-gable | Mansard |
|---|---|---|---|---|
| Mid-terrace | Often | Often | Rarely | Sometimes |
| End of terrace | Often | Often | Sometimes | Sometimes |
| Semi-detached | Often | Often | Often | Sometimes |
| Detached | Often | Often | Sometimes | Rarely |
| Flat or maisonette | Permitted development rights do not cover flats, so a conversion needs planning permission and the freeholder's agreement. | |||
Windows fitted into the existing roof slope. The most affordable and least intrusive option, but it requires enough existing height.
A structure that extends out from the rear slope, increasing both headroom and floor space. Commonly chosen for terraces.
The sloped side of a hipped roof is converted into a vertical wall, allowing space for a staircase and larger area.
The rear slope is transformed to be nearly vertical with a flat top. Offers the most space and often requires planning permission.
Six steps, in this order. Planning and party wall paperwork can run alongside the drawings.
Check the height, inspect the rafters, chimney positions, and potential stair locations.
Drawings by an architect and structural plans for steel beams and new flooring.
Assess planning needs, or obtain a lawful development certificate if it's under permitted development. Serve party wall notices if walls are shared.
Submit an application or building notice, then the inspector visits during the work.
Start with steelwork and flooring, then the roof structure, followed by stairs, insulation, electrics, and plastering. On-site time is a few weeks.
Get a completion certificate from building control. Keep it safe for any future buyers.
A loft conversion touches the structure of the house and the walls you share. These are the answers worth having in writing.
