Many Dudley properties benefit from loft conversions — Victorian terraces, 1960s semi-detached homes, and modern estates all have different requirements, and we've tackled them all.
Dudley has a diverse mix of property types — from Victorian terraces in town centre areas to modern estates on the outskirts. Each conversion type suits different homes and budgets. Here's what we typically recommend for Dudley properties:
Flat roof dormers are the most popular choice for Dudley homeowners who want maximum usable space and full head height. If your property has a traditional pitched roof structure, a rear dormer can add 100+ sq ft of living space while creating a contemporary extension aesthetic.
Common in: Victorian terraces and semi-detached properties across Dudley town centre and Bilston
Ideal for: Master bedrooms, home offices, guest rooms, or playrooms
Benefit: Creates rooms you can stand up in fully; modern exterior appearance
Hip-to-gable conversions are ideal for properties with a hip roof (sloped on all four sides). We remove the hip structure on one or both ends and replace it with a vertical gable wall, instantly creating additional headroom and usable floor space.
Common in: Semi-detached and detached homes across Gornal, Sedgley, and outlying Dudley areas
Ideal for: Creating full bedrooms without external extensions; maximizing existing roof space
Benefit: Cost-effective way to add significant space; no external footprint change
If you prefer a lighter-touch approach without major structural changes, roof window conversions add light and character to your attic space. We install premium Keylite and Velux roof windows to create bright, airy rooms.
Common in: Properties where planning permission might be restricted; listed properties
Ideal for: Home offices, studies, guest bedrooms, playrooms
Benefit: Rapid installation; no planning permission required in most cases; natural light and ventilation
Our portfolio speaks for itself. Here are some recent transformations we've completed for Dudley homeowners:
This Victorian semi benefited from a spacious rear dormer extension, creating a luxury master bedroom with an en-suite bathroom. The contemporary flat roof design complements the original property perfectly.

Every area has unique planning requirements and building control standards. We're fully accredited to work in all Dudley Council jurisdictions and maintain excellent relationships with local planning and building control teams.
From your first contact to moving into your new room, here's exactly how we work:
We visit your Dudley property to assess your loft space, discuss your vision, and explain your options. We review planning requirements, building regulations, and structural considerations specific to your property type.
We'll handle all the details. Most roof window conversions don't need permission, but dormers and hip-to-gable conversions often do. We prepare the plans and submit to Dudley Council on your behalf.
You'll receive a transparent, fixed-price quote with no hidden costs. We break down every element: materials, labour, timelines, and warranties.
Once you approve, we submit to Dudley Council's Building Control team and manage all compliance documentation.
Our skilled team handles the entire build, coordinating roofing, structural work, insulation, electrical, and finishing. Most conversions take 6-12 weeks depending on complexity.
We complete a full inspection, obtain your Building Control Completion Certificate, and provide ongoing support. Your new room is ready to enjoy.
