Velux Loft Conversions
Roof windows fitted into the existing slope bring in daylight and fresh air with minimal change to the outside of your home. A good choice where the loft already has enough headroom.

Loft & roof conversion specialists
Newcastle Roof Conversions designs and builds roof and loft conversions for homeowners across Newcastle upon Tyne who need more space but would rather stay put. We turn unused attics into bedrooms, home offices, en-suites and family rooms, with every design shaped around the roof you already have.
Our team works on terraced, semi-detached and detached houses, as well as bungalows. Each project starts with an honest look at your roof height, structure and staircase options, so you know early on which conversion will work and what it involves.

More space, same address
Moving home to gain one extra bedroom brings stamp duty, legal fees and the upheaval of leaving an area you like. A loft conversion uses space your home already has, which makes it a practical way to get the room you need.
Newcastle Roof Conversions handles the work from first survey and design through to construction and the finished room. Depending on your roof, we might fit roof windows into the existing slope, extend part of the roof with a dormer or rebuild the roof to a new shape. Whichever route suits your property, you deal with one company that understands each type of conversion.
View all servicesOur services
We offer six types of roof conversion, so our advice is based on your property rather than a single design.

Roof windows fitted into the existing slope bring in daylight and fresh air with minimal change to the outside of your home. A good choice where the loft already has enough headroom.
Explore Velux conversions
A dormer extends out from the roof slope to create vertical walls, more standing room and space for a double bedroom or en-suite.
Explore Dormer conversions
We replace a sloping side roof with a vertical gable wall, opening up the cramped loft space common in semi-detached and detached houses.
Explore Hip-to-Gable conversions
A mansard rebuilds the roof with a steep outer face and a flatter top, giving the largest internal floor area of any standard loft conversion.
Explore Mansard conversions
Two connected dormers, or a dormer on the side slope, make use of more of the roof on period terraces with rear outriggers.
Explore L-Shaped & Side Dormer conversions
When the existing loft is too low to convert, we raise the roof to create proper headroom for a new storey.
Explore Piggyback conversionsWho it's for
Most of our customers want an extra room without losing garden space or moving away from their area. Typical projects fall into a few groups.
A new bedroom in the roof frees up space on the floors below, and an en-suite takes pressure off the family bathroom at busy times of day.
A loft office sits away from the main living areas, giving you a quiet room with good daylight and a door you can close at the end of the day.
Rear dormers suit many terraces, while hip-to-gable conversions often work well on semi-detached homes with hipped roofs.
Some bungalows have enough roof height for one or two new rooms. Others need a raised or reshaped roof, which we can assess for you.
Costs & quotes
The cost of a loft conversion depends on the design you choose, the condition of the existing roof and how you want the finished room fitted out. A rooflight conversion usually involves less building work than a dormer, mansard or roof lift, so it generally costs less.
We price every project individually after looking at the property, so your quote reflects the work your home needs.

Approvals
Many loft conversions in England fall under permitted development, which means you won't need a full planning application if the design stays within the national limits. A Velux rooflight conversion or a modest rear dormer often qualifies, while larger roof extensions, changes to the roof height and homes in conservation areas usually need planning permission from the local council.
Building regulations approval applies to every habitable loft conversion. It covers the structure, fire safety and escape routes, the staircase, insulation and ventilation. On terraced and semi-detached houses, work that affects a shared wall may also fall under the Party Wall etc. Act 1996.
We check the planning position for your property at the start, so the design we propose is one you can build. Our step-by-step guide to the roof conversion process explains each stage in more detail.
Our process
We visit your home, measure the loft and talk through how you want to use the space. You'll find out which conversion types suit your roof.
We prepare the drawings and structural calculations, then deal with the planning and building control applications your project needs.
The build covers the structural work, roof alterations and windows, followed by insulation, the staircase, services and plastering.
Building control inspects the work at the required stages, and your new room is ready to use once it passes final inspection.
Areas covered
Newcastle Roof Conversions works throughout Newcastle upon Tyne and the surrounding area, including Gosforth, Jesmond, Heaton, Fenham, Kingston Park, Gateshead and Wallsend.
Housing varies a great deal across these neighbourhoods. Victorian terraces in Heaton and Jesmond often suit rear or L-shaped dormers, while many semi-detached homes in Gosforth have hipped roofs that lend themselves to a hip-to-gable conversion. We design each project around the individual building rather than the postcode.

Why us
Because we offer every main type of roof conversion, we can recommend the design that suits your loft and budget instead of steering you towards a single option. If a simpler conversion will give you the room you need, we'll say so.
You'll get clear advice on what your roof can and can't accommodate, a detailed quotation and regular updates once work starts. We take care of design, approvals and construction, which saves you coordinating separate trades and consultants.
Our team also understands the local housing stock and the planning considerations that apply across Newcastle, Gateshead and North Tyneside. Find out more about Newcastle Roof Conversions.
