Adding extra space to your home can be a game-changer. Loft conversions are a smart way to increase living space without moving. They bring new life to unused attic areas, turning them into functional rooms. Whether you want a bedroom, office, or playroom, there’s a loft conversion to suit your needs.
In this article, we’ll guide you through the popular loft conversion types, helping you understand which might work best for your home in Cardiff or South Wales.
Discover Popular Loft Conversion Types
When considering a loft conversion, it’s important to know the options available. Each type has its own benefits, costs, and suitability depending on your home’s structure.
Here are some of the most popular loft conversion types you might want to explore:
Dormer Loft Conversion

Dormer conversions are one of the most common choices. They involve building a box-like structure that extends out from the roof. This creates more headroom and floor space, making the loft feel larger and more usable.
Benefits: Adds significant space, simple design, and often does not require planning permission.
Ideal for: Homes with a pitched roof and limited loft height.
Uses: Bedrooms, bathrooms, or home offices.
Dormer conversions are especially popular in South Wales because they maximise space without altering the roofline too drastically.
Velux Loft Conversion

A Velux conversion is a simpler option. Instead of changing the roof shape, it involves fitting skylight windows flush with the roof slope. This lets in natural light and makes the loft feel airy.
Benefits: Lower cost, quicker to install, and usually no planning permission needed.
Ideal for: Lofts with enough head height but limited space for structural changes.
Uses: Small bedrooms, study areas, or storage.
This type is perfect if you want to brighten your loft without major construction work.
Hip-to-Gable Loft Conversion

This conversion changes the sloping side of a hip roof into a vertical wall, creating more space inside. It’s common in semi-detached or detached homes with hip roofs.
Benefits: Creates a large, square room, increases head height, and adds value.
Ideal for: Homes with a hip roof looking for a spacious loft.
Uses: Master bedrooms, large playrooms, or studios.
Hip to gable conversions are a great way to maximise space in homes typical of Cardiff and surrounding areas.
Mansard Loft Conversion

A Mansard loft conversion is one of the most transformative options available. It involves reshaping the roof to create a near-vertical rear wall and a flat roof, maximising headroom and usable floor space. This style blends beautifully with many property types.
Benefits: Significantly increases usable space, adds substantial property value, and allows for greater design
flexibility.
Ideal for: Homes where a larger, full-height living area or
extra bedrooms are desired.
Uses: Spacious master suites, multiple bedrooms, or open-plan living areas.
A Mansard conversion is perfect if you’re looking to add major living space and transform your loft into a fully functional part of your home.
What are the different attic conversions?
Attic conversions are similar to loft conversions but often refer to smaller or less extensive projects.
Here are some common "attic conversion" types you might find useful:
Basic Attic Conversion: Simply finishing the existing space with insulation, flooring, and lighting.
Room-in-Roof Conversion: Utilises the existing roof space without major structural changes.
Mansard Conversion: Involves altering the roof to create a flat roof with steep sides, adding a lot of space.
Each attic conversion type varies in cost and complexity. Choosing the right one depends on your home’s structure and your goals for the space.
How to Choose the Right Loft Conversion for Your Home
Choosing the right loft conversion depends on several factors.
Here’s what we recommend considering:
Roof Type: Check if your home has a pitched, hip, or flat roof. This affects which conversions are possible.
Head Height: You need at least 2.2 metres of head height for a comfortable loft conversion.
Planning Permission: Some conversions need permission, others don’t. Always check local regulations.
Budget: Costs vary widely. Velux conversions are cheaper, while hip to gable or mansard conversions typically cost more.
Purpose: Think about how you want to use the space. A bedroom needs different features than an office or bathroom.
Consulting with a professional builder can help you understand what’s feasible and get the best value for your investment.
