Swimming Pool Turned Pond Renovation at Buckhurst Estate, Sussex

A Remarkable Pond Restoration at Buckhurst Estate

Buckhurst Estate is one of Sussex’s most distinguished historic estates, set within extensive landscaped grounds shaped over generations. The gardens combine formal stonework, mature planting, and carefully positioned water features, all of which contribute to a setting rich in character and heritage.

Working within historic estate grounds requires a different level of care. Access is often restricted, existing stonework must be protected, and every intervention must respect the character of the landscape. This was not simply a pond refurbishment. It was a restoration within a historically sensitive setting.

At the heart of these grounds sits a substantial pond that appears, at first glance, to be a traditional estate water feature. However, as is often the case with historic landscapes, the true story lay beneath the surface.

This project quickly became far more than a routine refurbishment. It evolved into a careful and considered restoration requiring investigation, structural understanding, and a respectful approach to both the landscape and its hidden past.

Project Overview

Location: Buckhurst Estate, Sussex
Original Structure: Historic swimming pool converted to pond
Maximum Depth Discovered: Approximately 2.2 metres
Material Removed: Around 45 cubic metres of compacted infill
Access: Restricted estate access requiring partial manual removal
Final Finish: Full fibreglass lining with restored York stone edging

 What Looked Like a Simple Pond

At first inspection, the pond appeared to be a relatively straightforward refurbishment. It presented as a large estate pond with a visible maximum depth of around 1.2 metres and showed the typical signs of age associated with long established water features.

Surface discolouration, uneven sediment levels, and inconsistent depth readings suggested that alterations may have taken place at some point in its history. However, nothing visible from above indicated the scale of what lay beneath.

The initial plan was simple: drain the pond, remove accumulated silt and debris, inspect the structure, and prepare it for refurbishment.

As is often the case with older ponds, appearances proved misleading.

 A Discovery No One Alive Knew About

Once the pond was fully drained, it became immediately clear that this was not simply a pond. Beneath the visible base lay the remains of a former swimming pool that had been partially filled in and converted more than a century ago.

When working within historic estates, it is not uncommon to encounter undocumented alterations. However, uncovering an entirely intact swimming pool structure was exceptional.

As sediment and infill were removed, the original structure revealed itself. A sloping ramp led down into a fully formed deep end measuring approximately 2.2 metres. What had been assumed to be a modest 1.2 metre deep pond was in fact concealing a substantial historic swimming pool beneath decades of compacted material.

A visible white marking on the pond walls showed the original depth line, clearly illustrating how much of the structure had been hidden over time. This discovery fundamentally changed the scope and approach of the project.

Removing 45 Cubic Metres of Hidden Material

Before any restoration work could begin, the pond had to be completely cleared back to its original structure. In total, approximately 45 cubic metres of compacted mud, stone, and historic infill were removed.

Much of this material had effectively become structural through years of compression, masking the original geometry of the pool entirely. The removal process had to be controlled carefully to avoid destabilising the original structure. Material was taken out in stages rather than aggressively excavated, ensuring the integrity of the pool walls remained intact.

Although machinery was used to break up the compacted layers, strict access restrictions within the estate gardens meant that removal had to be carried out manually.

Bucket by bucket, the material was lifted from the pond and transported to a dumper beyond the immediate garden area. Over four demanding days on site, thousands of buckets were moved to fully expose the historic structure beneath.

It was a physically intensive stage of the project and a real testament to the team’s persistence and professionalism.

Structural Preparation and Full Fibreglass Lining

With the full extent of the original swimming pool now uncovered, we were able to assess the structure properly and prepare it for long term refurbishment.

Given the age and complexity of the structure, alternative lining systems would not have provided the same level of long term reliability. A full Fibreglass lining was therefore installed to create a seamless, structural waterproof membrane across the entire interior.

This system provides a durable, low maintenance finish capable of accommodating minor movement while protecting the integrity of the underlying structure. For large estate ponds, particularly those within historic settings, fibreglass offers reliability and longevity without compromising visual character.

Restoring the Surroundings and Water Feature

Once the interior was secured, attention turned to restoring the surrounding features.

The existing York stone edging was carefully lifted and relaid to retain the original aesthetic of the gardens while ensuring a clean, stable perimeter around the pond. The intention was not to modernise the pond, but to return it to a clean, structurally sound condition that sat naturally within the established landscape.

The water feature was rebuilt to suit the newly revealed depth and proportions of the pond. Because the pond was significantly deeper than originally believed, internal supports were installed to allow planting baskets and water lilies to sit at the correct height within the water column.

This ensured that planting could be reintroduced safely and proportionately, without compromising stability or visual balance.

A Stunning Result in a Historic Setting

Once refilled, the transformation was immediate. What began as a misleading, silt filled pond concealing a forgotten swimming pool was restored as a striking and elegant estate feature, entirely in keeping with its historic surroundings.

Large scale historic pond restorations demand a combination of structural understanding, careful planning, and physical resilience. This project brought all three together while respecting the heritage of the site.

From uncovering a long forgotten swimming pool to delivering a fully restored pond ready for its next chapter, this renovation stands as a memorable and genuinely special achievement.
