The brief

A family, and four derelict buildings.

The owners had taken on a late-Georgian ironstone farmhouse on the edge of Barby, listed at Grade II together with the outbuildings attached to it. The group had stood empty for years. One outbuilding had collapsed to a single end wall, and the yard had filled with later steel sheds pressed against the listed stone.

They did not want a museum piece. They wanted the ironstone, the sashes, the inglenook, the cobbled barn floor and the hayloft kept, and the four buildings woven into one family home.

Accommodation
One family home of about 477 sqm, some 5,130 sq ft
Route
Two consents were needed, listed building consent and full planning.
Our role
Architect and lead consultant, RIBA Stages 0 to 4 and the discharge of conditions.
The planning journey

Both granted, five days apart.

Planning journey for Barby Wood Farmhouse: survey and heritage assessment in autumn 2023; listed building consent applied for in November 2023; the council's ecology objection in April 2024; full planning applied for in July 2024; both consents granted in February 2025; and the scheme on site in 2026, with Rickett Architects acting as architect and lead consultant from the first survey through to RIBA Stage 4

Both consents were determined within five days of each other in February 2025. Refs 2024/0221/LBC and 2024/3116/FULL, West Northamptonshire Council.

As we found it

What was worth keeping.

Real heritage tangled up with later clutter. The survey separated the two, and the design followed it. Survey photographs, 2023.

The farmhouse

Empty, and growing over.

Late eighteenth century, coursed ironstone, three bays over two storeys and an attic. Sound in its bones, and empty for years.

The grain barn

A brick arch under corrugated iron.

Cobbled floor, timber hayloft, ventilation slits and a segmental brick arch, all of it swallowed by a later lean-to.

The later sheds

What grew up around it.

Corrugated sheeting and breeze block, built hard against the listed ironstone. No historic value, and assessed as detracting from the group.

The scheme

Four buildings, one house.

The farmhouse repaired and kept, each outbuilding given a use of its own, and the modern sheds cleared away.

The elevation

Four buildings read as one.

The three-bay farmhouse holds the centre, the converted outbuildings step down either side, and the modern sheds are gone. Repairs match the originals; the new work is kept quiet, so a later eye can still tell the two apart.

The consented front elevation. Windows and doors are retained and repaired like for like, by condition.

Scale and massing

What came down.

The grey is the farmstead as it stood. The line drawn over it is what the consents keep, so everything grey standing proud at either end is mass that goes.

Existing against proposed. The scheme is contained within the footprint of the existing farmhouse and outbuildings, and has less impact on its surroundings than what is presently on site.

The site plan

The yard given back.

The farmhouse and its three outbuildings sit around garden courtyards, reached by the existing track off Onley Lane. Clearing the steel sheds opens the group back up to the fields around it.

A hedgerow runs the full length of the access track. The landscaping steps down with the slope, so no safety railing is needed against the listed farmhouse.

Ground floor

Cinema, kitchen, barn.

Each outbuilding takes a use that suits what it already is. The small hipped outbuilding, most likely an old dovecote, becomes a cinema room. The collapsed outbuilding is rebuilt on its own footprint as a kitchen linking farmhouse to barn. The grain barn becomes the living and dining heart of the house.

One connected house rather than a set of rooms behind separate doors.

First floor

Bedrooms, and two mezzanines.

The barn keeps its full height, with a snug on a new mezzanine.

The detail

A floor that can breathe.

New insulated floors with underfloor heating are laid in beneath the converted barns, against underpinned stone walls.

Planning-stage drawing; the structural build-up is confirmed by the engineer at technical design. Condition 6 of both consents requires all new insulated solid floors to be in breathable limecrete.

The challenge

The listing reached the cobbles.

Listed inside as well as out.

The farmhouse and its three outbuildings are listed as one group, so the cobbled floor, the hayloft, the staircase and the windows were all protected. Then the council's ecologist objected.

Discuss your building
The gable end of the listed farmhouse at Barby Wood Farmhouse in 2023: coursed ironstone with a brick chimney stack and sash windows, with a modern steel-framed lean-to structure built hard against it and a concrete yard running away to a corrugated shed beyond

Four things at once: a Grade II listing that reached the interiors, an outbuilding collapsed to a single end wall, bats to survey for in the roof spaces, and great crested newts to assess on a site inside a red impact risk zone.

The full story

The protection ran through everything. The farmhouse and its attached outbuildings are listed at Grade II as a single group, so the listing reached the cobbled floors, the timber hayloft, the open-well staircase and the twelve-pane sashes, not just the front elevation. One outbuilding had already collapsed to little more than a single end wall. All of it sits in open countryside, with the canal conservation area beyond the site to the west.

So before drawing a line, the evidence came first. An independent heritage impact assessment recorded the group element by element and weighed every proposed intervention against what it would touch. Its conclusion, that the scheme would have a neutral to minor positive effect on the significance of the farmstead, became the spine of the planning case. Where the conservation officer wanted more, further written justification was submitted.

Then the ecology. In April 2024 the council's ecologist objected on three counts: the bat survey was not considered fit for purpose, the outbuildings proposed for demolition had not been surveyed for roosting features, and the site sits inside a great crested newt red impact risk zone. Bats can only be surveyed between May and August, so an objection landing in spring is the kind that costs a year. The bat work was extended across that season instead, and the newts were dealt with through the district level licensing scheme the council operates. Both consents were then issued within five days of each other.

What we did

Survey to site, one practice.

The team that recorded the buildings and made the heritage case is the same team that produced the technical design and cleared the conditions.

The heritage case

The survey came before the design.

Evidence
A full heritage impact assessment, recording the group element by element
Approach
Repairs the minimum necessary, in traditional materials to match the originals
Argument
Clearing the modern sheds lets the obscured stone outbuildings be seen in full, and outweighs the loss of one ruin
Kept
The layout of the formal front rooms and the first-floor bedrooms, left as it is
Outcome
Heritage impact assessed as neutral to minor positive across the farmstead

A collapsed outbuilding rebuilt on its own footprint was judged a moderate positive, not a loss.

The ecology

A licence, not a lost year.

Problem
The council's ecologist objected: the bat survey was not fit for purpose and the outbuildings for demolition were unsurveyed
Bats
Seasonal surveys of the roof spaces and lofts, run through the May to August window
Newts
Routed through the district level licensing scheme the council operates, the site being in a red impact risk zone
Outcome
The objection resolved inside the same survey season it landed in

External lighting and a biodiversity plan then came through as conditions of the planning consent.

After consent

Consent, then the conditions.

Conditions
An archaeological watching brief, materials samples, and schedules for the windows and the timbers
Staircase
Dismantled by hand, its components salvaged and reused, and reconstructed with approval
Floors
All new insulated solid floors in breathable limecrete, so the old walls can still dry out
Technical
Stage 4 design alongside the discharge of the heritage conditions
On site
The works are under way, with the farmhouse under repair and the outbuildings stripped back

Our appointment runs to Stage 4 and the discharge of conditions. The build itself is with the contractor.
