Loft conversions vs basement conversions: which should you choose?

Loft or basement conversions are the ideal solution when you are looking to upgrade or expand your house without moving to a new home. There are perks and downsides to both, and we have outlined them all so you can choose which version is best for your lifestyle. 



Basement conversion: 


  • Having a basement improves the value of your property, as more customers will be attracted to a house with a luxurious underground pool or second living room. 
  • Basements are a flexible space which can be made into a family den, home cinema, media room, or gym. The downside to this is that it is unusual to add an underground bedroom, and the other sorts of rooms are usually more expensive to build. 
  • If you are looking to create a rented space for guests, then basements can have separate access, which is particularly useful. 
  • You can make your basement quite large, as it depends how deep you dig, and it can be as long as your garden is. 


  • On average basements are more expensive to create than lofts; a lot of them need to be made from scratch, which means extra costs for excavation.   
  • Basements are not an option for every property, they are usually only possible for detached or semi-detached houses. 
  • An obvious con would be that basements don’t have windows, and so can feel quite closed in. 
  • Unlike lofts, basements always need planning permission.
  • The time it takes to create the basement will increase when it needs excavation.
  • In some cases you have to move out of your house while conversion is under way, as it can be quite disruptive. 
  • It is more difficult to protect a basement from damp.

Loft conversion:


  • Converting your loft adds about 20% onto the value of your home.
  • A loft can become another bedroom, or another living area, and this makes your house more appealing to buyers.
  • There are several options for what you can turn the loft into, such as a studio, a recreation room, an office, or a bedroom.
  • There is a much easier process for development rights when you choose to convert your loft. It is quite simple to get it approved and you don’t always need planning permission.
  • Nearly every type of house can have the loft converted into a functional extra room, including attached or detached houses. 
  • If you live in a suburban area without significant views, then a loft can add extra height to your building so you can enjoy a nicer view. 
  • Lofts are bright, open and airy, which makes them a lovely space to relax in.
  • The construction process of converting a loft is usually simple and so is completed quite quickly.


  • There are some restrictions to the height of a loft, but you can always raise the roof, lower the ceiling below, or utilise the pitch in the roof. 
  • The size of the room will also be limited by the size of your loft, but by adding large windows, the views and light can make any space feel bigger. 
  • You can turn a loft into less types of rooms.
