Top 6 Luxury Basement Conversion Ideas: Builder’s Guide

Basement extensions have been a popular response to the lack of living space for decades in areas like Kensington, Chelsea or Fulham. Getting a conversion done allows property owners to add any new functional room. Many West London residents use this new space to have an extra bedroom for guest, a spacious family room or a bespoke kitchen, but if you are not in a need of these rooms, you can think about more luxurious solutions. Here are Nu Projects’ top tips on high-end basement fit-outs!

1. Pool

The past year has taught us a good lesson about healthcare and wellness. With the temporary closure of wellness centres and the lack of beach holidays, our desire to escape the world and relax has increased. Getting a double-height basement done in West London has multiple benefits; it will allow you to have a basement pool, so you can go for a swim in the comfort of your home and it will increase the resale value of your property.
