How we design loft conversions at Salstan
At Salstan Architecture, our approach to loft conversions in London is focused on creating additional space that feels like a natural part of the home, not an afterthought. We start by assessing the existing roof structure, head height, and layout potential to establish what type of loft conversion is most suitable, whether that is a dormer loft conversion, hip to gable, mansard, or a rooflight conversion. From the beginning, we look at how the new stair will sit within the house and how the loft conversion will improve the overall flow and balance of the home.
We then develop a loft conversion design that prioritises usable floor area, natural light, and comfortable room proportions. This includes careful placement of dormers or roof windows, sensible ceiling lines, and practical storage solutions that make the space feel generous and efficient. Externally, we ensure the loft conversion respects the character of the property and the wider street scene through appropriate scale, materials, and detailing, particularly for period homes and conservation sensitive settings.
