Running out of space? Tired of bumping your head in that cramped loft area?

A dormer loft conversion might just be the perfect solution you’ve been searching for.

Unlike simple Velux installations, dormers create proper rooms. Real headroom. Usable floor space that actually feels like… well, a proper room.

What is a Dormer Loft Conversion?

Think of a dormer as a box that pops out from your roof. It’s a structural extension that creates a vertical wall where your sloped roof used to be.

The result? Instant headroom and dramatically more floor space.

Dormer conversions work by building a box-like structure that projects from the main roof plane. This creates a vertical wall with windows, giving you proper standing height throughout most of the converted space.

Most dormer conversions feature a flat roof or pitched roof design, depending on your property type and local planning requirements. The vertical wall typically includes one or more windows, flooding the space with natural light.

Why Choose a Dormer Over Other Conversion Types?

Simple question: do you want a cramped space where you can barely stand up, or a proper room?

Dormer conversions offer several key advantages over Velux or simple roof light conversions:

Maximum usable space. Where Velux conversions leave you with awkward angled walls, dormers create proper rectangular rooms with full headroom.

Better furniture placement. Try positioning a wardrobe against a sloped wall. Not happening. Dormers give you vertical walls that actually work for furniture.

Enhanced natural light. Vertical windows in the dormer wall provide better light distribution than roof-mounted Velux windows.

Improved ventilation. Vertical windows open more effectively than roof lights, creating better airflow.

Are you currently using your loft as storage because it’s too cramped for anything else? A dormer conversion transforms unusable space into a room you’ll actually want to spend time in.

Types of Dormer Conversions

Not all dormers are created equal. The type you choose depends on your property, budget, and space requirements.

Shed Dormers feature a flat roof and extend across most of the rear roof slope. These create maximum internal space and work brilliantly for larger properties.

Gable Dormers have a triangular, pitched roof that matches your main house roof. They’re smaller than shed dormers but often integrate better with traditional property styles.

Hip-to-Gable Conversions extend the roof to create a vertical gable wall. Technically not a dormer, but often grouped with dormer projects due to similar complexity and planning requirements.

Combination Approaches might include a dormer on one side and Velux windows on another, maximizing both space and cost-effectiveness.

North East Loft Conversions specialises in all dormer types, with Oliver and Steve’s team bringing decades of experience to each project design.

Planning Permission: What You Need to Know

Here’s where dormer conversions get a bit more complex than simple Velux installations.

Most dormer conversions require planning permission. The structure extends beyond your existing roof line, which takes it outside permitted development rights in many cases.

When planning permission is definitely required:

• Dormers facing the front of your property
• Dormers extending beyond certain size limits
• Properties in conservation areas or with Article 4 directions
• Listed buildings or buildings in Areas of Outstanding Natural Beauty

The planning process typically involves:

• Detailed architectural drawings
• Structural calculations
• Planning application submission
• 8-week determination period for most applications
• Building regulations approval (separate from planning)

Worried about planning permission or building regs? North East Loft Conversions handles all planning and building regulation applications, removing the stress and ensuring compliance with local requirements.

The company’s 20+ years of experience means they understand which designs get approved and how to navigate potential planning challenges.

The Dormer Conversion Process: Step by Step

Wondering what actually happens during a dormer conversion? Here’s the realistic timeline:

Weeks 1-2: Design and Planning Initial site survey and detailed design work. This includes structural calculations and architectural drawings for planning applications.

Weeks 3-10: Planning Permission Planning application submission and determination period. Complex projects might take up to 13 weeks, while simpler designs often get approved in 8 weeks.

Weeks 11-12: Pre-Construction Building regulations submission and approval. Material ordering and project scheduling.

Weeks 13-24: Construction Phase The actual building work typically takes 10-12 weeks for dormer conversions, depending on size and complexity.

Construction phases include:

• Roof opening and structural work
• Dormer frame construction and weatherproofing
• Internal insulation and plasterboard installation
• Electrical and plumbing first fix
• Flooring installation
• Second fix electrical and plumbing
• Decoration and final finishing

Is your growing family starting to outgrow your current home? The construction timeline might seem long, but the transformation is remarkable.
