Which confers a higher value?

[OrangeBloo]

Hello Mumsnetters,

Which of these would you say confers higher value onto a property?

Ground floor currently has one bedroom, family bathroom, living room, dining room and kitchen.
Extension planned to create open plan kitchen-diner-snug, add a utility room, convert family bathroom to smaller shower room.

First floor currently has 2 bedrooms with a sink in one, nothing else. There's a large loft space hence extension is planned to add one bedroom, family bathroom, en-suite and walk in wardrobe to master bedroom.

So ultimately, with the first floor extension the house will have 4 bedrooms; one on ground floor, and 3 on first floor.

Reason I am asking is, we have received quotes for these and can fully fund the first floor extension with current savings however, the ground floor extension costs twice as much. Hence, I was thinking if we did the first floor extension first and then remortgage to fund the ground floor, that might be a good approach. However, I wanted to have some idea of what would confer better value to a house so we might be able to get the most from the bank to fund the intended works.

Thank you for any advice.

IN MY Opinion, the first floor extension will add more value as it is increasing the shared living space, making the home more conducive to entertaining, and improves parts of the home that are utilized by more people.

First floor would add more value. You're adding a bedroom and 2 bathrooms, taking your house from a 3 to a 4 bed, that's a massive change.
Ground floor extension sounds great and kitchens are one of the most important rooms in the house but ultimately no-one would buy a house no matter how lovely the kitchen is if it doesn't have enough bedrooms. And a lot of people would also rule out a house with no upstairs bathroom.
However, I'd do the one that will make the most difference to you and your family in your day to day lives as you are the ones living there. And the one you can afford to fund.

The first floor extension sounds like what more people would want so I would do that with a view to resale.

I suggest having a word with estate agents in your area. They’re usually happy to give their opinion.

Adding a bedroom is usually what adds most value to a property. However you should ask an estate agent in your area.

Thank you everyone for your responses which are all unanimous and also in alignment with my own research.
The plan is to make it our forever home but presently we can only afford the cost of the first floor extension so we'll go ahead with that for now. Hopefully, we can then remortgage to fund the ground floor.

Appreciate you all taking the time to write a response. Have a lovely day.
