The types of Loft Conversions that we work in - Cricklewood
Cricklewood sits in that part of North West London where the housing is solid, the streets are established, and moving to something bigger costs a lot more than it used to. For most families here, building up makes more sense than moving out. A dormer is where that process usually starts. We extend the rear roof slope with a flat-roofed box structure, giving you full standing height and a proper room layout. Cricklewood has a strong mix of Victorian terraces and inter-war semis both housing types respond well to this conversion. The front of your house stays as it is. The work happens at the back, and the gain inside is real and immediate. Best for: Victorian terraces, inter-war semis, and Cricklewood homes where the loft has potential but head height is holding it back.
Walk down most streets in Cricklewood and you'll notice something about the rooflines a lot of them slope inward at the sides. That's a hipped roof, and while it looks fine from the outside, it quietly takes a chunk out of your usable loft space. A hip-to-gable conversion puts that right. We replace the sloping side with a straight vertical wall, recovering the width that the hipped roof was eating into. It's a change that makes a real difference to how the loft can be used and when combined with a rear dormer, the result is a layout that feels like a proper floor rather than a converted attic. Best suited for: Semi-detached and end-of-terrace homes in Cricklewood where the hipped roof is quietly limiting what the loft can become.
Not every loft in Cricklewood needs a major structural build. Some of them just need the right finishing and a Velux conversion is exactly that. We fit roof windows into the existing slope, reinforce the floor, upgrade the insulation, and make sure everything meets building regulations. The roof doesn't change. There's no structural work, no external alteration, and no lengthy timeline. What you're left with is a bright, well-finished room that uses the space that was already there. In parts of Cricklewood where planning restrictions apply particularly near conservation zones this is often the most practical and sensible route. Best for: Cricklewood homes with good existing head height, homeowners working to a budget, and properties where external changes need to stay minimal.
Cricklewood has a lot of terraced and semi-detached homes that have been extended at the rear over the decades. If that sounds like yours, there's more potential above your head than a single dormer can capture. An L-shaped conversion uses both roof sections. One dormer on the main roof, one above the rear extension, joined together to form the L shape. The combined floor area is significantly larger than a standard dormer and it's realistic to fit two bedrooms and a bathroom up there without any of the rooms feeling like an afterthought. For Cricklewood families who've outgrown their current layout, this is the conversion that tends to settle the question of whether to stay or move. Best for: Cricklewood homes with rear extensions, families needing multiple new rooms, and terraced properties where a single dormer won't go far enough.
Some Cricklewood homeowners don't just want more space they want to go as far as the roof will allow. A mansard conversion is built for exactly that. We rebuild the entire rear slope at a near-vertical angle with a flat roof running across the top. The loft stops being a loft and starts being a floor. Full ceiling height, maximum usable area, and a finish that sits naturally with the character of the house. It's the most involved conversion we do, and it usually requires planning permission from Brent or Barnet Council depending on where in Cricklewood you are. But for the right property, nothing else comes close to what it delivers. Best for: Larger period homes, properties on the Brent and Barnet border, and Cricklewood homeowners who want the most ambitious and highest-value conversion available.
They're easy to overlook, but Cricklewood has its share of bungalows and most of them are sitting on far more roof space than their owners have ever thought to use. A bungalow roof covers the full footprint of the property. That means a loft conversion here can yield a surprising amount of floor area enough for one or two proper rooms that change the entire dynamic of the home. The ground floor opens up, the household gets more breathing room, and the property itself becomes significantly more valuable. It's one of the more underestimated conversions we carry out in this part of London. The results tend to speak for themselves. Best for: Single-storey Cricklewood homes where the ground floor has nothing left to give, and owners who want a meaningful, lasting improvement without the upheaval of moving.

Not always. Some house loft conversions can qualify for Permitted Development, but the exact property and proposed design must satisfy the applicable conditions and local restrictions.
Cricklewood crosses local-authority boundaries, and conservation-area or Article 4 controls can differ. The responsible council and property-specific planning history should be checked first.
Often, yes. A rear dormer can provide significantly more usable floor area, but the design needs to respect the existing roof and planning context.
Potentially, particularly on suitable semi-detached or end-of-terrace properties with hipped roofs. Structural and planning checks are required first.
Yes. Examples include the Railway Terraces Conservation Area in Barnet and Mapesbury Conservation Area on the Brent side of the wider Cricklewood area.
Yes, where the available floor area, staircase, drainage, ventilation and structural design can accommodate both spaces.
It can be considered for suitable properties, but a mansard is a substantial roof alteration and normally requires a more detailed planning and design assessment.
Different planning rules apply to flats and maisonettes, and freeholder or leaseholder consent may also be required.
It is often less expensive because it involves fewer major external roof alterations, although the actual cost depends on the property and specification.
A broad 2026 London guide places many dormer projects around £45,000–£80,000, with larger or more complex conversions potentially costing more.
Yes. Planning permission and Building Regulations are separate, and the construction must satisfy the relevant technical requirements for habitable accommodation.
Start with a roof survey and planning assessment. This establishes what the property can accommodate and which conversion route is realistic before detailed design begins.
