Nine ambitious British conservation projects

Caring for hundreds of historic houses and gardens requires constant effort to make sure everything stays in tip top condition. This year we're once again working hard to secure the future of our special places with a bold programme of restoration and conservation projects. Here are nine of our most ambitious projects.

Trees at Dyffryn Gardens

Dyffryn Arboretum, Glamorgan 

We've begun a five-year project to protect the beautiful plants in our arboretum. Our plan is to focus on one section of the Arboretum each year, opening up overgrown spaces, clearing areas around our important trees and propagating from those that are reaching the end of their lifetime.

Hermitage on the Long Walk at Kedleston Hall as it looks today

Kedleston Hall, Derbyshire 

We're busy restoring the Hermitage on Kedleston's Long Walk. There are very few surviving hermitages. We want to ensure that visitors can experience this one as an 18th-century visitor might have and use it as a place for quiet relaxation and contemplation. We also hope to restore the Long Walk as well.

Lindisfarne Castle on Holy Island off the Northumberland Coast

Lindisfarne Castle, Northumberland 

The exposed location of Lindisfarne Castle means that the fabric of the building is under constant pressure from the elements. Over the years this has caused penetrating damp, deterioration of the stonework and pointing, as well as damaging windows and letting in water. Right now we're working to fix these problems and secure Lindisfarne Castle for future generations.

Quarry Bank, Cheshire 

We're hard at work restoring our highly unusual curvilinear glasshouse to its former glory. The work is guided by information we've gathered from the archives including photographs, letters, diaries, maps and garden plant orders. Where possible, we are using original materials in the rebuilding process to ensure an authentic restoration.

Seaton Delaval Hall, Northumberland 

This major conservation project will be beginning a key phase in 2017 as we work to tackle important conservation issues across the site. We will be working to stabilise buildings, walls and structures in the landscape and around the main hall. As well as reinstating the designed gardens, re-roofing the West Wing and completing important masonry and timber repairs.

South Cottage Garden at Sissinghurst Castle Garden, Kent

Sissinghurst Castle Garden, Kent 

The magical creation of Vita Sackville-West and Harold Nicolson, Sissinghurst Castle Garden is renowned the world over. Vita’s loose, romantic style of gardening has been compromised over the years by high horticultural standards and, whilst these standards remain, work is underway to gently return the garden to her more amateur, profuse, experimental planting and a refuge dedicated to beauty.

Before restoration: early days working on the swimming pond

Standen House and Garden, West Sussex 

About 10 years ago a group of volunteers discovered an abandoned swimming pond whilst clearing out some overgrown bamboo. It was part of the Arts and Crafts-inspired garden created by Margaret Beale at the end of the 19th century and early 20th century. The discovery sparked a major restoration and conservation project that aims to reinstate the splendour of the original garden.

Scaffolders at work in the courtyard at Tredegar House

Tredegar House, Newport 

We're embarking on a programme of conservation projects to safeguard the future of our beloved 17th-century mansion house and its surrounding gardens and parkland. 'Lifting the Lid' will see the repair and redevelopment of a number of areas of the property, including the mansion house roof, chimneys and windows, with possible developments to the glasshouses and bothies and the stable block, among many other areas.

North side to The Vyne mansion during roof conservation works

The Vyne, Hampshire 

We've got big things planned for the Vyne. This magnificent building is currently in the middle of a major roof restoration and conservation project. Although the first floor is closed for the duration of the work, the ground floor has an exciting new layout. In early 2017 we will have a rooftop walkway with a 360 degree view that is accessible to all.
