If your loft feels cramped or lacks usable headroom, a dormer loft conversion could be the perfect solution. By extending the existing roof vertically, dormers create a full-height room with plenty of natural light—making them ideal for a master bedroom, home office, or stylish living space.
At Loft Conversions Newcastle (LCN), we specialise in tailored dormer conversions that maximise both space and value. Whether you’re in a terraced house in Jesmond or a semi in Gateshead, our expert team will guide you through every step—from planning and design to build and finish.
Here’s why homeowners across the North East choose LCN for their dormer loft conversions:
More headroom – perfect for taller furniture and comfortable movement
More space – great for larger bedrooms, bathrooms, or even open-plan living
Natural light – large windows or Juliet balconies flood the space with daylight
Versatile design – available with flat, gabled, or hipped roofs to match your home
Planning-friendly – often classed as permitted development
We manage the entire process—including all planning permissions if required—ensuring your project is smooth, stress-free, and built to the highest standards.

A single dormer conversion adds a box-shaped extension to one side of your existing sloped roof, instantly increasing headroom and usable space. It’s a popular choice for homeowners looking to add a small bedroom, home office, or en-suite without a full roof restructure.
This style is ideal for smaller homes and can often be built under permitted development, making it a simple and cost-effective upgrade.
A double dormer conversion features two dormers—one on each side of the pitched roof—creating a more balanced, spacious layout. This design allows for greater natural light, enhanced ventilation, and significantly more floor area.
Perfect for larger homes or families needing two new rooms (e.g. bedroom and bathroom), double dormers offer flexibility, space, and strong return on investment.
An L-shaped dormer combines two connected dormers at a right angle, typically extending over both the main roof and rear extension. This layout is especially suited to Victorian and Edwardian terraced homes or semis with rear outrigger structures.
It’s one of the most space-generous conversions, often large enough to accommodate multiple rooms—such as a bedroom, bathroom, and walk-in wardrobe—all in one build.

Understanding permitted development rights is key if you're planning a loft conversion without applying for full planning permission. In many cases, homeowners can extend their roof space under these rights making loft conversions quicker, easier, and more cost-effective to carry out.
For most detached and semi-detached homes, permitted development allows you to add up to 50 cubic metres of roof space. This means that popular options like dormer or hip-to-gable loft conversions often don’t require planning permission, provided certain conditions are met.
However, it’s important to note:
-
Flats and maisonettes do not have permitted development rights
-
Properties in conservation areas or with previous extensions may have restrictions
-
You’ll still need to meet building regulations and may require a Lawful Development Certificate for peace of mind
-
At Loft Conversions Newcastle (LCN), we’ll assess your property and handle all planning checks on your behalf—so you can move forward with confidence.
