New Loft Version (NLV)

Revolutionising the Design of Loft Conversions

Simplified Explanation of Innovative Loft Conversion Design

Making Loft Conversions Easier for Homes with Low Roofs.


Turning your loft into a usable room can be difficult, especially if your house has a low roof. Many homeowners run into problems with building rules and planning permission. Traditional methods often can't solve these issues, especially if you want to have a loft conversion with limited height or add height to your loft.


Our new design changes this. It lets homeowners create loft conversions even when the roof is quite low (as low as 1.4m, depending on the survey). Thanks to recent rule changes by the government, our approach is now even more helpful. It even helps homeowners keep the storage space that is often lost in regular loft conversions and have a full loft conversion.


One big advantage is that our system usually avoids the need to apply for planning permission. Instead of raising the roof ridge (which often requires planning), our design gets extra height without changing the ridge. For ridge heights of 1.8m or more, there’s no need to lower the ceiling on the floor below. This isn’t magic—it’s the result of over 35 years of experience in loft conversions and carpentry, combined with a specially registered design.


Key Features of the NLV Design

  • Works with Most Roofs: Our design fits almost all pitched roofs (except mono-pitched roofs), so more homeowners can use it.
  • Low Roofs Welcome: The system works even for roofs with very low ridges, starting at 1.4m (subject to survey).
  • Adaptable for Larger Spaces: For gable roofs up to 2.3m ridge height, homeowners can make the most of their permitted space without needing garden extensions.
  • Planning Permission Not Needed: Because we don’t raise the ridge, our method usually stays within permitted development rules, speeding up the process.
  • More Room, More Height: When adding a rear dormer, our design gives much more usable height at the back than typical methods, all while staying within the rules.
  • Flexible Licensing: The design’s license is linked to both your home and you as the homeowner, with options for ease of use, subject to our licencing agreement.
