The types of Loft Conversions that we work in -
Dormer loft conversions are one of the most popular choices in Barnet, particularly for semi-detached and detached homes on residential streets. This conversion adds a box-shaped extension to the rear of the roof, giving you more headroom and usable floor space. It's a practical way to create an extra bedroom, home office, or en-suite without changing the front of your property. Barnet homes from the 1930s and 1940s are especially well-suited to this style. Best for: Homes with limited head height, period semi-detached or detached houses, and properties where gaining extra internal space is the main goal.
A lot of homes in Barnet have hipped roofs, the kind where the sides slope inward rather than ending in a flat gable wall. A hip-to-gable conversion replaces that sloping section with a vertical wall, opening up significantly more space inside. This style works especially well when paired with a rear dormer, giving you a large, open loft layout that feels like a proper room rather than an attic. Best suited for: Semi-detached or detached homes in Barnet with hipped roofs, and homeowners looking to make the most of the full roof footprint.
A Velux conversion is the simplest and most affordable route. We don't touch the roof structure; instead, we fit roof windows into the existing slope, reinforce the floor, add insulation, and bring everything up to building regulations. If your loft already has decent head height, this option gets the job done without the cost or complexity of a structural build. Best for: Barnet properties with enough existing loft height, tighter budgets, or where a low-disruption conversion is preferred.
If your Barnet home has a rear extension, an L-shaped dormer is worth considering. We built one dormer over the main roof and another over the back addition, connecting them to form an L shape. The result is a large, flexible loft that can easily fit two bedrooms and a bathroom — without things feeling cramped. Best for: Larger period homes in Barnet with existing rear extensions, or families who need more than one new room.
A mansard conversion rebuilds the rear slope of the roof at a near-vertical angle with a flat top. It's the most involved type of conversion, but it gives you the most space, essentially a full extra floor. Planning permission is usually required, but for the right property in Barnet, the result is worth it. Best for: Larger homes, character properties, and homeowners in Barnet who want to maximise every inch of space with a high-end finish.
Barnet has plenty of bungalows, and many of them are perfect candidates for a loft conversion. Adding one or two rooms upstairs frees up the ground floor for open-plan living or makes the home more accessible for family members who find stairs difficult. The wide roof footprint typical of Barnet bungalows means there's usually plenty of room to work with. Best for: Single-storey homes where ground-floor space is already stretched, and owners are looking to future-proof their property.
