🌿 The quiet before the house fills up again…

Fresh flowers on the table, the last few touches being done, and Glansevin is nearly ready to welcome today’s guests through the doors.

There’s something lovely about these few quiet hours before a new stay begins. Soon there’ll be bags in the hallway, voices carrying through the house, people finding their rooms and everyone settling in for a few summer days together.

August at Glansevin has been a busy one — exactly how we like to see the house: full of people, celebrations, family and friends making the most of summer in the Carmarthenshire countryside.

For now though, everything is ready and waiting. 💛

🍂 Just one September weekend is left at Glansevin… and it comes with a special 10% off.

September has filled up beautifully, and we now have just one full weekend remaining — 25th–27th September 2026.

So if you’ve been looking for an excuse to gather everyone together for a countryside break in Wales, this might be it.

Come for the weekend, arrive a little earlier or stay a little longer, and make the most of a September escape in the Carmarthenshire countryside.

Glansevin is an exclusive-use country house in Wales with 20 bedrooms sleeping up to 42 adults, so it’s perfect for getting everyone under one roof. Whether it’s a family gathering, milestone birthday, reunion with friends, anniversary, or simply a good excuse to get away together, you’ll have the whole house and grounds to yourselves.

Think pool time, long evenings, cosy corners, shared meals, and time to properly relax with your favourite people.

For our remaining September 2026 dates, we’re offering a special 10% off new direct bookings 🌿

If 25th–27th September happens to be sitting empty in everyone’s diary, this could be your sign.

Get in touch and we’d be very happy to talk through the different stay options.

Another summer stay is about to begin at Glansevin 🌿

Fresh flowers on the table, a little Welsh welcome waiting, the doors open onto the garden… and one more family about to make the house their own for a few days.

August in the Carmarthenshire countryside is looking rather lovely from here. Long summer evenings, garden lunches, dips in the pool, exploring the Bannau Brycheiniog and plenty of space to simply switch off and spend time together.

That’s what we love about family stays at Glansevin. Whether it’s a birthday, an anniversary, a family reunion or simply an excuse to gather everyone in one place, you have the whole house and grounds exclusively to yourselves.

A country house in Wales, full of character, surrounded by countryside — and ready for the next set of memories to begin.

Welcome to Glansevin 💛

How gorgeous is this personalised travel-themed wedding cake by Ivy Cottage Cakes? 🌍✈️

Such a thoughtful surprise for the couple, and it looked perfectly at home here at Glansevin. We’re so pleased to have Ivy Cottage Cakes as one of our recommended suppliers — and even more delighted that they’ll be back with us again next year 🥰

Last weekend I had the pleasure of making and delivering this travel themed wedding cake to
This cake was a surprise for them from Mum, the bride & groom love exploring the world, so a travel themed cake, including a world map and mini suitcases. I also pin pointed in the map (by using edible pearls) countries they had visited together.
Glansevin is such a beautiful venue and I’m so pleased to be a recommended supplier for them. I’ve already booked another wedding cake for there for next year! I can’t wait to visit again 🥰
