Home Sellers

One of the simplest yet most effective ways to boost your property's value is by selling it with approved planning permission. This strategic move allows you to unlock the full potential of your property without the need for any construction having to take place.

Research indicates that having approved planning permission alone can increase your property's value by approximately 10%. Showcasing these approved plans to potential buyers enables them to visualise the possibilities and how they can enhance their new home right after purchase, without the typical delays and costs associated with obtaining planning permission.

We recommend speaking with your local real estate agents to gain a more precise understanding of by how much having approved planning permission can significantly elevate the market value of your property.
