Kate Middleton and Prince William are currently enjoying quality time with their new baby daughter, Princess Charlotte, and Prince George at their country retreat, Amner Hall, in Norfolk.
And, after spending a cool £1.5 million renovating the country mansion, they now want to add to the 10-bedroom Georgian pad with a new tennis court.
The Duke and Duchess of Cambridge have submitted planning permission for the astroturf court to the local borough council.
According to the Daily Mail, King's Lynn and West Norfolk council received the planning application, by surveyor Andrew Holt, from the Sandringham Estate office.
The proposal says: "The current tennis court needs extensive work to resurface and we have been advised that to resurface we need to remove all the existing court and start again.
"In doing so the landscape designer has recommended that the court is moved away from current position to the proposed position which involves taking a very small area of Parkland to provide sufficient space around the court.
"The area concerned does not form part of the Ancient Monument and will not have any impact on the Agricultural tenant as the land is so small.
According to the Mirror, the proposal adds: "On completion of the new court the garden will be prepared to reinstate the fencing and re-erect the parkland iron fencing.
"The topsoil from the new site will be used to reinstate the existing court area with the old hard surfacing taken off site for recycling."
Council planners are likely to reach a decision by mid-August, and a planning notice is online for the public to submit comments by the end of July.
Anmer Hall was built in 1802 and is set on the Queen's 20,000-acre Sandringham Estate.
It already boasts a swimming pool and acres of beautiful rolling countryside - and, possibly, it will soon have a gleaming new tennis court to add to its impressive list of features.
