Bespoke loft conversions in Chislehurst, designed and built by our own in-house team. One fixed price, a ten-year guarantee, and a free design survey on your doorstep.
Chislehurst is mostly period detached houses on larger plots, with significant conservation area coverage, and that is what decides which conversion your roof will take. We have spent over twenty-five years working on exactly this kind of property across London, so we know what these roofs allow before we get the tape measure out.
Chislehurst has large conservation areas and a number of listed buildings. Designs need to be sympathetic and a full planning application is common.
Chislehurst has large conservation areas and a number of listed buildings, so the planning route is the first thing to establish rather than the last. Designs need to be sympathetic to the street, and a full application is common rather than exceptional.
The houses are mostly period detached properties on larger plots, which means the roofs are big and the potential is real. What limits the job is usually what the conservation area will accept on the visible elevations, not what the structure will take.
Whether you need an extra bedroom, an en-suite or a home office, a loft conversion adds the space without the cost and upheaval of moving out of Chislehurst, and it can add up to twenty percent to your property's value.
Given the housing in Chislehurst, these are the conversions we build here most often. On your free survey we confirm exactly which one your roof allows.
The most popular conversion in London. A dormer extends out from your sloping roof to add full head height and real floor space, ideal for a terrace or a semi.
Explore dormer conversions →The answer for homes with a sloping, hipped side roof. We build the hip up into a vertical gable wall, squaring off the roof and unlocking a full-size room.
Explore hip to gable conversions →Building the end wall of your home straight up to the roof ridge gives you a tall, square room with real presence, and the height for a striking window.
Explore gable conversions →Where a standard loft falls short on height, reshaping the roofline itself unlocks the headroom and floor space a plain conversion cannot reach.
Explore roofline conversions →Where your roof already has the height, a Velux conversion is the most cost-effective way to gain a bright new room, with roof windows set neatly into the existing slope.
Explore velux conversions →The largest conversion we build. Two dormers combined over the main roof and the rear addition, giving you the space for more than one room.
Explore l-shape conversions →Planning a new build, or want the loft designed in from day one? We build the space in from the start, or convert an existing new-build roof into a proper room.
Explore new build conversions →It depends on the type of conversion and the shape of your roof. A Velux conversion, where the head height already exists, costs less than a full dormer or an L-shape that adds a whole floor of space. Because Chislehurst homes are mostly period detached houses on larger plots, with significant conservation area coverage, most conversions here are dormer or hip to gable builds, which sit in the middle to upper part of that range. You can see indicative ranges on our costs page.
