Project Overview

A Grade II listed Georgian property on the outskirts of Sevenoaks. Owners in residence for sixteen years, having inherited a 1990s pine kitchen the previous occupants had installed in the 1990s — functional, not unkind, but recognisably late-twentieth-century in a room that wanted to look as though it had always been there. The brief was period authenticity, not pastiche. Materials that age the way the rest of the house has aged. Nothing visibly modern unless modernity served the room.

The property's listed status set the rules. Listed Building Consent (LBC) was required for any works affecting character — cabinetry, flooring, fixed fittings, the wiring runs visible at chimney breasts. We took the project from first survey through full LBC application before any tool went near the property. The local conservation officer reviewed and consented twelve weeks after submission, with two minor requested amendments around lighting fittings and a request for the original lath-and-plaster ceiling to be retained. Both were agreed without issue.

Site programme on the build itself ran four weeks. Short, because there was no structural work to do — no walls to remove, no partitions to add, no extension to coordinate. Long-feeling, because the four weeks were dense: every cabinet hand-painted on site, every reclaimed brick laid individually in lime mortar, every brass fitting hand-aged before installation. Handover took place at the end of the fourth week. The clients hosted a lunch the following Saturday for the previous owners, who had stayed in touch. The previous owners said the kitchen looked like it had always been there. The clients felt that was the only review that mattered.

The Client Brief

The brief came from both owners over four design meetings. Their priorities were unusually clear and unusually specific:

The Challenge

A four-week period kitchen on a Grade II listed building has a small number of large constraints, most of them set before the build itself begins.

Listed Building Consent

LBC was required for cabinetry, flooring, fixed fittings, lighting, and any wall finishes affecting character. We led the application: scaled drawings, materials schedule with samples, heritage statement justifying material choices, lighting plan, and ceiling preservation strategy. Submitted to the local planning authority, twelve weeks of determination, two minor amendments requested and agreed, consent issued. Build started the following Monday.

Hand-Painting On Site

Spray-finished factory paintwork was rejected. The clients wanted brush texture, the subtle visual unevenness of an on-site hand-applied finish that ages the way old paint ages. The cabinetmaker delivered carcasses primed only. Three coats of eggshell were brushed by hand on site over four days, with sanding between coats. Four times slower than spray. The right answer for the room.

Reclaimed Brick Floor in Lime Mortar

The reclaimed brick was sourced from a Kent farm building demolition: 600 hand-cleaned bricks, individually selected for colour, wear pattern and edge condition. Laid in herringbone over a UFH-compatible screed, pointed with traditional lime mortar (not modern cement), allowed to cure for ten days before sealing with a breathable wax. A cement mortar would have been faster and entirely wrong for the building.

Exposed Firebox Restoration

The original chimney breast firebox had been boxed in behind plywood by previous occupants in the 1990s. We removed the box and discovered intact period brickwork inside, soot-blackened, with the original iron range hooks still in place. The brickwork was carefully cleaned with soft brushes only (no chemicals), repointed in lime mortar where loose, and the original hooks left in situ as a heritage feature. The new electric AGA was set in front of, not into, the chimney breast.

Electric AGA Wiring Through a Listed Building

An electric AGA needs a 32A dedicated circuit. The route from the consumer unit was constrained by the listing — no chasing into original walls, no surface-mounted plastic conduit, no obvious modern intrusions. We routed the supply through the existing voids behind the skirting and dressed it with brass-finish surface conduit at the visible drop to the AGA position. Visible run, just under three metres, no chase damage to original fabric.

Copper Sink in an Oak Worktop

An apron-front copper sink in an oak butcher-block on the island is a specific assembly. Copper expands and contracts with hot water; oak is a natural material that moves seasonally. The sink was rebated into the oak with an EPDM expansion gasket, sealed with a colour-matched neutral-cure silicone, and the oak was treated four times with food-safe oil before installation to slow moisture transfer. Tested at install with a full-bowl boiling water immersion. No movement, no leak.

Our Approach

Period kitchens on listed buildings succeed or fail on three things that most contractors don't even start: leading the LBC application properly, sourcing materials that age right rather than materials that look good when new, and tradespeople who know the difference between cement and lime mortar without having to look it up.

Owning the LBC application from day one. Most contractors will tell you the LBC application is the homeowner's job, or the architect's. We led ours: scaled drawings, materials schedule with samples, heritage statement, lighting plan, ceiling-retention strategy. Submitted in our name, conservation officer questions answered by us in writing within 48 hours, two minor amendments agreed without delay. Twelve-week determination, no extensions, no resubmissions.

Materials that age into the building, not against it. Every material on this build was chosen for what it would look like in twenty years, not at handover. Unlacquered brass is bright at install and warmly tarnished at year five; copper sink develops a complex bronze-and-verdigris patina; oak butcher-block stains and marks with use; lime-mortared reclaimed brick gradually loses dust and softens; honed Welsh limestone develops a soft sheen across the high-traffic zones. The room was designed to peak at year ten, not at handover.

Heritage trades who know the work, not generalists with a YouTube tutorial. The cabinetmaker is a single bench joiner who works alone and produces twelve to fifteen kitchens a year. The brick-layer for the floor is a mason who works on listed buildings exclusively and mixes lime mortar by hand to traditional ratios. The painter spent four days on site brushing eggshell. None of these are general-build trades. We schedule them as named individuals, not as "the joiner" or "the painter".

The lath-and-plaster ceiling stayed. The original ceiling was repaired, not replaced. The hairline crackle is part of the room. We covered it carefully through the build, repaired three small loss areas with horsehair plaster from a heritage supplier, and left the rest exactly as found. The conservation officer's site visit at handover commented specifically that the ceiling was the most-correctly-handled element of the project.

The Build Process

Twenty working days from strip-out to handover. Four weeks of dense, slow, period-appropriate craft work. The 12-week LBC determination period sat before week 1 and is not counted in the on-site programme.

00
Pre-Site

Listed Building Consent (12 weeks)

Survey, design, materials schedule, scaled drawings, heritage statement, lighting plan and ceiling-retention strategy prepared by us. LBC application submitted to local planning authority. Twelve-week determination. Two minor conservation officer amendments agreed (lighting fittings spec, ceiling repair methodology). Consent issued. Site start date set for the following Monday.

01
Week 1

Strip-Out, Survey & Discovery

Existing 1990s pine kitchen carefully removed. Plywood-boxed chimney breast removed, original firebox brickwork discovered intact with period iron range hooks. Floor lifted: existing concrete subfloor noted, suitable for UFH overlay. Original lath-and-plaster ceiling protected and minor loss areas marked for repair. Cabinetmaker on site for site-measure of bespoke cabinetry. Brick supplier confirmed 600 reclaimed bricks available from Kent farm demolition.

02
Week 2

First Fix, UFH & Firebox Restoration

Electrical first fix: 32A dedicated AGA circuit routed through skirting voids with visible drop in brass conduit, no chasing of original walls. Plumbing first fix: hot/cold to copper sink position on island, brass-fitted bridge mixer. UFH manifold positioned, pipework laid across the room over insulation board, screed poured Friday. Firebox brickwork hand-cleaned, repointed in lime mortar, original iron range hooks left in situ. Ceiling loss areas repaired in horsehair plaster.

03
Week 3

Brick Floor Laid & Cabinetry Delivered

Reclaimed brick floor laid Monday-Wednesday in herringbone pattern over the cured screed, pointed in traditional lime mortar with raked finish. Lime mortar left to cure undisturbed for the rest of the week. Bespoke handmade cabinetry delivered Friday morning — primed only, no paint applied. Carcasses installed against perimeter walls Friday afternoon, ready for hand-painting in week 4.

04
Week 4

Hand-Painting, AGA, Worktops & Handover

Cabinetry hand-painted on site Monday-Thursday: three coats of eggshell brushed by hand, sanding between coats, brass cup handles and bar pulls hand-aged and fitted. Honed Welsh limestone perimeter worktops templated Tuesday and fitted Thursday. Oak butcher-block island top fitted Wednesday with copper sink rebated and EPDM-gasketed. Electric AGA delivered and commissioned Friday morning. Lighting circuits commissioned, brass pendants hung, snag walkthrough Friday afternoon. Handover at the end of week 4, conservation officer site-visit signed off the following Tuesday.

Project Specifications

The technical detail behind a kitchen built to age into a Georgian listed building rather than away from it.

Cabinetry

Handmade in-frame Shaker by single bench joiner. Solid timber face frames, 22mm carcasses, hardwood drawer boxes with hand-cut dovetails. Delivered primed only. Three coats of brushed eggshell hand-applied on site in soft heritage white, sanding between coats. Solid unlacquered brass cup handles and bar pulls, hand-aged before fitting.

Perimeter Worktops

Honed Welsh limestone, 30mm thick, soft matte finish, double bullnose front edge. Allowed to mark and patina with use. Sealed only with traditional limestone wax (no resin sealer) to maintain the soft hand of the surface.

Island Worktop

Solid oak butcher-block, 60mm thick, finger-jointed strips, food-safe oiled finish (four oilings before installation, monthly oiling thereafter for first six months). Will stain and mark with use as intended. Sink rebated and EPDM-gasketed for thermal expansion.

Sink & Tap

Apron-front antiqued copper farmhouse sink, single deep bowl. Unlacquered — allowed to develop natural verdigris-and-bronze patina. Brass period-style bridge mixer with porcelain lever handles. No boiling-water tap (the AGA boils water on the hob faster than a Quooker, per the clients' preference).

Range Cooker

Electric AGA-style four-oven range. 32A dedicated circuit. Continuous-warmth design (always on, low background temperature with zone-by-zone boost), giving the room ambient heat and reading visually as the heart of the kitchen. Set in front of, not into, the original chimney breast.

Flooring

600 reclaimed Kent stock bricks, hand-cleaned, individually selected for colour and wear. Laid in herringbone pattern over UFH-compatible screed. Pointed in traditional lime mortar with raked joints. Sealed with breathable carnauba wax. Period-correct, breathable, UFH-compatible.

Underfloor Heating

Wet UFH system, 16mm pipe at 200mm centres, 65mm screed cover under the brick. Single-zone control via Heatmiser Neo Smart thermostat tied into existing oil-fired boiler. Surface temperature limited to 26°C to protect the lime-mortared brick from thermal stress.

Lighting

No recessed downlights (LBC condition). Three brass pendant fittings over the central island, two brass surface-mounted spotlights at the cooking and prep zones, plus brass picture lights above the dresser-style perimeter cabinets. Three switched and dimmable circuits. Brass switchplates throughout with porcelain rocker switches.

The Finished Result

What was delivered

A period country kitchen on a Grade II listed Georgian property, delivered against a four-week fixed-price contract on site (preceded by twelve weeks of LBC determination), with no variation orders, no conservation officer pushback, the original lath-and-plaster ceiling intact, the original chimney breast firebox restored to a feature rather than concealed behind plywood, and a reclaimed brick floor that reads as if it has always been there. Every material chosen will look better at year ten than it does at handover — the brass will tarnish, the copper will patina, the oak will stain, the limestone will soften.

The previous owners of the property visited the following week, and their comment — that the kitchen looked as though it had always been part of the house — was the brief landed in a sentence. The conservation officer's sign-off four days after handover, citing the ceiling preservation specifically, closed the LBC file. The clients reported six months later that they had spilled red wine on the oak butcher-block within the first fortnight, were initially horrified, and now consider the resulting darker mark to be the room's first piece of patina.

What the Client Said

We've owned the house for sixteen years and we wanted a kitchen that looked like it had always been here. The previous kitchen was lovely but not us. We had three contractors quote. Two of them treated the listed status as something the homeowner needed to sort out before they showed up. Building Group treated it as their job. They wrote the LBC application, answered the conservation officer in writing, and only then started ordering materials. Once on site they brought in a single bench joiner who works alone, a brick mason who only does listed buildings, and a painter who spent four days on the cabinets with a brush. The pine kitchen was gone in a morning. The new one took four weeks. We've spilled red wine on the oak island, scratched the limestone with a saucepan, and the copper sink already has a darker rim around the tap that we're delighted with. The room is doing exactly what we asked it to do, which is to age slowly and warmly. We'd use them again without hesitation.
