Types of Loft Conversions in Northampton
At Swiss Build, we specialise in loft conversions in Northampton, helping homeowners transform unused attic space into beautiful, practical living areas. Depending on your roof structure, budget and space requirements, there are several types of loft conversions to choose from.
Roof Light (Velux) Loft Conversion
A roof light loft conversion is the most straightforward and cost-effective option. This type uses the existing roof structure, with Velux windows installed into the roof slope to bring in natural light. Because there are no major structural changes, it is often quicker to complete and ideal for lofts with sufficient head height. This is a popular choice for homeowners looking for a simple bedroom, office or hobby room.
Dormer Loft Conversion
Dormer loft conversions are the most common type in Northampton. A dormer extends vertically from the existing roof slope, creating additional headroom and usable floor space. This option significantly increases room size and allows for standard windows, making it perfect for bedrooms with en-suites or larger living areas. Dormer conversions suit most property types, including terraced, semi-detached and detached homes.
Hip-to-Gable Loft Conversion
A hip-to-gable loft conversion is ideal for semi-detached or end-of-terrace properties with a sloping side roof. This conversion extends the sloped “hip” roof into a vertical “gable” wall, dramatically increasing internal space. It is often combined with a rear dormer to maximise room size and functionality.
Mansard Loft Conversion
A mansard loft conversion involves altering one or both roof slopes to create near-vertical walls and a flat roof section. Although this is a more extensive structural change, it delivers the greatest increase in space and can completely transform your home. Mansard conversions are common on terraced properties and in urban areas.

Great service from Neil, he went out of his way to fit a Hive thermostat on a Sunday, we were very impressed with his workmanship and how clean and tidy he was. I would definitely recommend Swiss Build and use them in the future.

I cannot recommend Swiss Build in Northampton highly enough. I recently had some building work completed, and the entire team was respectful, professional. Everything was exactly as agreed, with no hidden costs, and the project was completed within the stated timeframe. I would happily recommend Swiss Build to anyone looking for reliable and skilled builders.
