Not Sure Which Loft Conversion Is Right for You?
Every property has a different roof structure, layout and planning context, which means there’s no one-size-fits-all solution when it comes to loft conversions. At Art & Build Ltd, we help homeowners in Croydon and across London choose the most suitable loft conversion based on their space, budget and long-term goals.

If you are comparing different options, our guide to dormer vs Velux loft conversions explains how the two popular choices differ in cost, structure, space and suitability.
Common Types of Loft Conversions
We design and build all major types of loft conversions to suit different roof structures, planning requirements and property styles commonly found in Croydon and London. Below is an overview of the most popular loft conversion options and how they are typically used.
These figures are general guide prices. For a fuller breakdown of typical costs, hidden extras and what affects the final quotation, read our guide to loft conversion cost in Croydon.
Dormer Loft Conversion
A dormer loft conversion is one of the most popular and versatile options. It involves extending the existing roof to create additional head height and usable floor space, making it suitable for most pitched roofs.
Best suited for:
- Additional bedrooms with an en-suite bathroom.
- Home offices or guest rooms.
- Maximising head height and usable floor space.
Dormer conversions often fall under permitted development and work especially well for terraced and semi-detached homes in Croydon and across London.
If you are comparing dormer and rooflight options, read our guide to dormer vs Velux loft conversions.
Typical loft conversion cost in Croydon and London: £35,000 – £60,000+ depending on layout, specification and level of finish.
L-Shaped Dormer Conversion
An L-shaped dormer is commonly used on period homes where the rear roof forms an “L” shape. It creates a large continuous loft area and is ideal when you want maximum space at the back of the property.
Best suited for:
- Victorian and Edwardian terraced houses
- Large master bedrooms with an en-suite and storage
- Creating a spacious full-width loft layout
This option is popular across South London where traditional property styles allow for a bigger rear conversion.
For a more detailed breakdown, see our guide to L-shaped loft conversions in Croydon, including layout ideas, costs and project considerations.
Typical cost in Croydon and London: £65,000 – £85,000+ depending on layout, specification and level of finish.
Hip-to-Gable Loft Conversion
A hip-to-gable loft conversion extends the sloping side of a hipped roof to form a vertical gable wall, increasing internal space and making the loft easier to layout.
Best suited for:
- Semi-detached and detached homes
- Properties with hipped roofs
- Lofts that need more width for a practical room layout
Hip-to-gable conversions are often combined with a rear dormer to further improve space and head height.
Typical cost in Croydon and London: £40,000 – £65,000+ depending on roof structure, specification and planning requirements.
Mansard Loft Conversion
A mansard loft conversion involves major roof alteration to create a near-vertical rear wall and a flat roof, delivering the maximum possible internal space and a high-end finish.
Best suited for:
- Homes where maximum additional space is the priority
- Full-width loft conversions with premium layouts
- Properties where planning permission is achievable
Mansard loft conversions usually require planning permission for loft conversions in London and are a strong option when you want a significant transformation.
Typical cost in Croydon and London: £55,000 – £95,000+ depending on complexity, specification and approvals.
Velux (Rooflight) Loft Conversion
A Velux loft conversion uses roof windows to bring in natural light without altering the roof shape. It’s typically the quickest and least disruptive option, ideal where there is already sufficient head height within the loft.
Best suited for:
- Lofts with good existing head height
- Home offices, guest rooms or hobby spaces
- Projects where minimal structural work is preferred
This option is popular with homeowners looking for a cost-effective conversion that improves light, comfort and usability without major construction works.
Even with a simpler rooflight conversion, good insulation is essential for comfort. Read our guide to loft insulation explained before planning the build-up.
Typical cost in Croydon and London: £20,000 – £30,000+ depending on insulation, electrics and internal fit-out.
Bungalow Loft Conversion
A bungalow loft conversion is designed for single-storey homes, creating a full additional level of living space. Thanks to generous roof volume, this type of conversion can deliver a significant transformation.
Best suited for:
- Bungalows and chalet-style homes
- Creating a new floor with bedrooms and an en-suite
- Major space increases without extending outwards
This type of project usually involves structural upgrades such as new floor joists, stair positioning and roof strengthening.
Typical cost in London: £50,000 – £90,000+ depending on structure, layout and level of finish.
