Corsham Loft Conversions is a family run team with more than 50 years of combined experience delivering loft conversions, attic conversions, and wider house renovation work across Chippenham, Bristol, and the surrounding towns and villages. Our team handles everything in house: design and planning, manufacture, and final fit, covering hip to gable extensions, dormer builds, and Velux installations, alongside general house conversion projects for homeowners looking to add space without moving.

Our Services
When it comes to loft conversions, Corsham Loft Conversions knows the process inside out. With over 50 years of combined experience, our team turns unused loft space into a functional room with ease. Whatever the project, our focus is on getting the design right from the outset and delivering seamless project completion for every house renovation we take on, not just a quick fit-and-forget job. The services we provide include:
- Bespoke Carpentry and Joinery
- Bespoke Staircases
- Deluxe Conversions
- Hip-to-Gable Attic Conversions
- L-Shaped Dormer Conversions
- Mansard Conversions
- Modular Loft Conversions
- New-Build Work
- Property Surveys
- Rooflight Conversions
- Skirting and Architraves
- Windows and Doors
- Wood Flooring
As your local loft conversion company, we also handle building regulations approval and, where needed, full planning permission applications for larger loft extensions such as mansard or dormer designs. These approvals ensure your new room meets current safety and structural standards, giving homeowners and commercial clients confidence that the finished house conversion is fully compliant.
Design-Led Loft Conversions, Planned and Built In House
At Corsham Loft Conversions, we manage every loft conversion as a full design and build project. That means the same team who draws up your plans also carries out the first and second fix carpentry, joinery, staircases, and finishing work, so nothing gets lost between different subcontractors partway through the job.
Every quotation comes with a guarantee agreed upfront, so you know exactly what’s included before work begins. We’re fully qualified and insured, with City & Guilds and NVQ Level 3 carpentry qualifications within the team, and we’re proud to say a large share of our work comes through recommendations from homeowners we’ve already helped across Bristol and the surrounding villages.
A loft conversion can create a new bedroom, a playroom, a home gym, a hobby room, a home cinema room, a music room, or a master bedroom with an en-suite and extra bathroom, depending on what your household actually needs. We talk through the options during the design stage, so the finished room gets used properly rather than becoming an expensive storage space, and every attic conversion is planned around how your family actually lives.




Fully Qualified, Insured, and Customer Focused
Our team is City & Guilds qualified and NVQ Level 3 trained, with every trade, carpentry, joinery, staircases, and flooring, carried out in house rather than passed on to subcontractors. We’re fully insured, customer focused, and proud to be highly recommended by past clients across the area, thanks to a straightforward approach and a strong standard of finish on every project.
Keeping every trade in house also means fewer delays. There’s no waiting around for a separate joiner, plasterer, or flooring contractor to become available, since the same team that starts the job carries it through to completion. For domestic clients this usually means a shorter time between the first survey and moving into the finished room, and for commercial clients it means less disruption to a working building while the project is underway.
