Frequently Asked Questions


Q. Do I always need planning permission?

A. It isn't always necessary to get planning permission, we can assess whether it's required in your initial free consultation.


Q. When requesting a consultation on extending our home do both partners need to be there?

A. Due to the complexity of the job, it makes sense for everyone living in the home to be involved. It lets us answer all of your questions right there, as well as explain in detail the entire process without wasting time and money on extra visits.


Q. How long does it take to build a house extension? 

A. It's very dependent on the size of the extension, the number of storeys, as well as obtaining planning permission, designs and so forth. Our experience ensures that everything goes to plan and we complete the work in an efficient and timely manner without delays.


Q. What guarantees do we have?

A. We provide an insurance backed guarantee (also known as an IBG), that not only covers any deposits paid but also the workmanship should we cease trading, meaning our guarantees on your house extension are much more than a piece of paper, giving you complete peace of mind and the confidence for Hillrose Property Services to complete the work for you.


Q. We don’t know where to start planning our house extension, can you help?

Our expert team have years of experience when it comes to planning a house extension, and are able to help with the entire process from start to finish.


Q. Will a house extension add value to my home?

A. In most cases, yes. A quality house extension can add up to to 23% to the overall value of your property (based on a study by Nationwide in 2015). However, the housing market is constantly changing so nothing is guaranteed.
