About
Kelmarsh Hall is an elegant Palladian country house in rural Northamptonshire, designed by the celebrated architect James Gibbs and completed in 1732. Set within sweeping parkland and surrounded by beautiful gardens, the hall offers visitors an intimate experience of English country house life spanning three centuries, from its Georgian origins through its remarkable 20th-century transformation by the legendary interior decorator Nancy Lancaster.
The house was built for the Hanbury family and passed through several owners before being acquired in 1928 by Ronald and Nancy Tree. Nancy Lancaster, an American-born socialite who became the most influential interior decorator of her generation, transformed Kelmarsh's interiors with her signature style blending English grandeur with American comfort — a look that came to define the English Country House aesthetic adopted by decorators worldwide. Her work at Kelmarsh, alongside her later achievements at Ditchley Park and Haseley Court, established the template for what became known as the 'Colefax and Fowler' style.
The hall's Gibbs-designed architecture features a harmonious Palladian facade with a central portico, elegant reception rooms with fine plasterwork, and a graceful staircase hall. The gardens, restored and developed over decades, include a formal walled garden, herbaceous borders designed in the style of Norah Lindsay, a sunken garden, and extensive parkland with ancient trees. Civil War connections add historical depth — the Battle of Naseby was fought nearby in 1645, and the grounds contain earthworks from this pivotal English Civil War engagement.
Now managed by the Kelmarsh Trust, the hall opens seasonally for guided tours and hosts a popular programme of events including garden festivals, outdoor theatre, and craft fairs.

💡 Visitor Tips
- The hall is open seasonally, typically April to September, Thursday to Sunday. House visits are by guided tour only — check the website for tour times and book in advance for popular dates.
- The gardens can be explored independently and are worth a visit even if you don't take a house tour. The walled garden is at its best in June and July when the herbaceous borders are in full bloom.
- Kelmarsh is in rural Northamptonshire with limited public transport. A car is strongly recommended. The hall is well signposted from the A14, just off Junction 2.
- The Kelmarsh Festival of History and other major events draw large crowds. Book early and expect busier conditions on event days. Regular visiting days are much quieter.
- Free parking is available on the estate. During major events, overflow car parks are opened and stewards direct traffic.
- Allow at least two hours for a comprehensive visit including the house tour and gardens. On a fine day, the parkland walks extend the visit further.
- Bring a camera for the gardens — the walled garden herbaceous borders and Palladian facade are particularly photogenic. Interior photography during guided tours may be restricted.
- The tea room serves light lunches and afternoon teas using local produce. It is a pleasant spot to relax after exploring the house and gardens.
Highlights
James Gibbs Palladian Architecture
Kelmarsh Hall is one of the finest surviving works of James Gibbs, the architect best known for St Martin-in-the-Fields church in London and the Radcliffe Camera in Oxford. Completed in 1732, the hall's Palladian facade features a central portico with Ionic columns, symmetrical wings, and the harmonious proportions that characterise the best Georgian country house design.
The architecture reflects the refined taste of the early 18th century, when English landowners looked to classical antiquity and the work of Andrea Palladio for their ideal of civilised living.
The interior retains fine plasterwork ceilings, elegant reception rooms, and a graceful staircase hall that demonstrate Gibbs's command of both exterior composition and interior spatial design.
Nancy Lancaster's Interior Design
The hall's interiors bear the transformative mark of Nancy Lancaster (1897-1994), the American-born decorator who virtually invented the English Country House style that influenced taste worldwide. After acquiring Kelmarsh in 1928 with her husband Ronald Tree, Nancy created interiors that blended 18th-century English grandeur with American warmth and comfort — a revolutionary approach at a time when English country houses were often cold, dark, and uncomfortable.
Her use of faded chintz fabrics, carefully arranged furniture groupings, fine antiques mixed with comfortable modern pieces, and her genius for colour and atmosphere established the aesthetic later codified by Colefax and Fowler.
Several rooms retain elements of Nancy's decorative schemes, providing a rare opportunity to see her work in situ.
The Walled Garden
The beautifully restored walled garden is a highlight of any visit to Kelmarsh, featuring herbaceous borders designed in the style of the celebrated garden designer Norah Lindsay, who advised Nancy Lancaster on the gardens during the 1930s. The borders are planted with a rich mix of perennials, roses, and seasonal bedding that provide colour from spring through autumn.
Espaliered fruit trees line the walls, and productive beds grow heritage vegetables and cutting flowers.
The walled garden perfectly complements the Palladian elegance of the hall, creating an enclosed world of colour, scent, and beauty that embodies the English gardening tradition at its finest.
The Staircase Hall
The elegant cantilevered staircase is one of the hall's most impressive interior features, rising through the centre of the house with graceful curves and fine wrought-iron balustrading. Natural light falls from windows above, illuminating the plasterwork and creating an effect of spacious grandeur that belies the hall's relatively modest scale.
The staircase hall demonstrates James Gibbs's skill at creating dramatic interior spaces within Palladian proportions, providing a theatrical setting for the guided tour's ascent to the upper floors.
Family portraits and artworks line the walls, adding to the sense of a lived-in country house rather than a sterile museum display.
Collections
Kelmarsh Hall's collections reflect the taste and lifestyle of an English country house across three centuries, with particular emphasis on the influential interior decorating of Nancy Lancaster during the mid-20th century. The hall contains Georgian furniture, family portraits, fine plasterwork, period decorative arts, and elements of Nancy Lancaster's celebrated interior schemes.
The building itself — James Gibbs's Palladian design — is the principal heritage asset.
The gardens, including the Norah Lindsay-influenced walled garden and sunken garden, form an integral part of the visitor experience. Interpretation covers the hall's architectural history, its social history from Georgian origins through the Lancaster era, and connections to the English Civil War.
