Extension vs. Outbuilding vs. Loft Conversion

When we dream about having extra space in our home it is best to consider maximising functionality, and investment potential. Whether you want to use the extra space for a bedroom, a living space, a home office or a home gym, there are the pros and cons 

associated with them:


Loft Conversion

I will only consider doing this if I am thinking of an extra bedroom, but you have to be sure that you have enough headroom in the loft.

  • Pros:
    • This space is private
    • You will be able to make use of an empty space
    • Will bump up the value of your home considerably
  • Cons:
    • This is probably the most expensive of the three because ideally you would want a room with a bathroom in there and it will set you back above £35,000
    • Definitely not for a home gym due to vibration
    • Stairs could take up some space on the floor below

  • Pros:
    • This is best if you are thinking of expanding your living space. You can definitely spill out if you are hosting a big party
    • Easy reach of the front door if you often expect someone to come to knock on your door
    • The close proximity to the kitchen means you have extra amenities available for you during your working hours if you want the extension as your home office
    • Services are easy to tap into. Radiator/s can be connected to your existing boiler.
    • Will bump up the value of your home considerably
    • This can work well if you want to move your kitchen in the new extension. If you want to know more about refurbishing kitchen click here
  • Cons:
    • Not the best option if you would like to use it for your home office as it does not create the separation
    • It can be distracting if you have someone watching TV in the Living Room, whilst you are working or reading a book in the extension



To me, this is probably the best option if I want a home gym. You can also use this for office, and also a living space as your summer house.

  • Pros:
    • Will not disturb other occupants in the house if you are “pumping iron”
    • Quick to build. Order from the brochure and pay. The building can be erected in a day or two
    • Cheapest
  • Cons:
    • Can potentially get too cold in the winter, hence extra electric heating and extra insulation required.
    • Being totally disconnected, you may need a few things if you want to use it as an office i.e. coffee machine, fridge.
    • You need to invest in services to connect to the main house
    • You have to go back to the main house if you want to use the loo.
    • Will not bump up the value of your home as much as the other two. There are some gains, but not as much compared to other options.
