Loft Conversion Design

Designing your loft conversion is a crucial stage – both planning permission and building work are based on these designs, which is why we partner with some of London’s finest architects to ensure that your needs are interpreted and drafted perfectly.

Architect Drawings

Avian works with RIBA qualified architects, with years of experience working on residential and commercial properties throughout London. Some of our architects may create 3D images to walk you through their proposed plans before putting together a detailed specification. If you choose to work with our architects, they will also submit your planning application to the local council and produce full working drawings for our team to follow throughout the project.

Building Control

Our loft conversion designs are based on your brief, but also meet all building control and general standards within building regulations to provide a safe, durable space for your family. Building control will visit the site are various stages throughout your loft conversion build to inspect the work. While they may suggest alterations, we have honed our design process over the past decade to ensure that these are minimal and very rarely required.

While you can choose whether the local council or a private company complete the building control inspections, both will work to the same set of guidelines. Final completion certifications are always required for loft conversions that are being used as living spaces and have permanent staircases.


Loft Design Considerations

While there are essential elements to a loft conversion design (set out by building regulations), there is a huge amount of flexibility meaning that you can create the perfect space for your family.

When working with our team to create or amend your loft conversion design, it’s worth considering:

  • Implications to the rest of the house – in most instances, the biggest change to the rest of the house is the staircase that goes to your new loft. However, if you live in a conservation area alterations to the roof may not be permitted. In that case, we may need to lower the ceilings in the storey below.
  • Sound proofing – building regulations for soundproofing are not very rigorous, so it’s best to add more than necessary to provide privacy and reduce disturbances.
  • Furnishing – loft conversions can have unusual angles which makes furnishing a challenge. A number of clients overcome this with custom furniture that is designed to suit your loft conversion. It’s also important to remember that your furniture needs to travel up the staircase – if you have opted for a narrow staircase, it may be difficult to put a sofa or other large items in your loft conversion.
  • Proportions – getting the most out of your loft conversion means using the space intelligently. While more rooms may seem more functional, larger rooms often provide more comfortable surroundings and a better atmosphere in the loft.
