Case study  /  Leamington Spa

A Regency terrace, two consents won.

A Grade II listed home. A rebuilt garden wall, and an orangery off the music room.

The facts

Listed building consent in Leamington Spa.

Two linked consents on one Grade II listed Regency home, run back to back: a garden wall, then an orangery.

The project

Two consents, one listed home.

2consents, both granted
Building
One half of a Grade II listed Regency terrace, built 1828 to 1836
Setting
A Leamington Spa conservation area
Client
A private homeowner, and a returning client
Consents
Warwick District Council, April 2024 and December 2024
Status
Wall built. Orangery consented, owners taking it forward

On a listed building the protection reaches the curtilage, so even the garden wall needed consent.

The brief

A bigger garden, and more light.

The owners live in one half of a handsome Regency house, divided into two homes a century ago. They had bought part of the garden next door and wanted to make the most of it: first by enclosing the enlarged garden with a wall in keeping with the house, then by opening the ground floor to it.

Both ideas sat on a listed building, so nothing could happen without consent, and on a house of this quality the bar for protecting historic fabric is high.

Phase one
A reclaimed-brick boundary wall, an extended outbuilding and a new pedestrian access
Phase two
An orangery of about 8.5 sqm off the music room, a new ground-floor WC and a re-planned cellar stair

The planning journey

A wall, then an orangery.

Planning journey for a Grade II listed Regency house in Royal Leamington Spa: Rickett Architects instructed again by a returning client in 2023; the garden wall application made in early 2024; listed building consent for the wall granted on 25 April 2024; the wall built over the summer of 2024; the orangery application made in August 2024; and consent for the orangery and internal alterations granted on 11 December 2024

About a year, and two separate listed building processes run back to back on the same house, each with its own heritage justification and drawings.

The drawings

Nothing changes from the street.

The work happens at the rear and along the boundary, in materials and proportions taken from the house itself.

The section

Where new meets old.

The glazed room and its lantern set against the rear wall, with the opening into the music room kept to double-door width.

A double-door opening removes less historic fabric than a wide aperture, and keeps the alteration reversible. That detail is the heritage case.

The ground floor

A better connected plan.

Three moves on one floor: the orangery off the music room, a new WC by the stair, and the cellar stair re-handed to make room for it.

The site

A long garden, newly enlarged.

Shown on its side to fit the page. The house sits at one end and the garden runs away from it, with the new wall closing the far boundary.

The challenge

Even the garden wall was listed.

Listing reaches all the way to the garden wall.

A listed building's protection extends to its curtilage, so a new boundary wall needed consent in its own right. One misjudged detail could have turned a domestic project into a refusal on a protected home.

Three things had to hold at once: historic fabric protected, the alteration kept reversible, and a new wall with foundations designed around mature trees and agreed with the neighbour.

The full story

Because the house is Grade II listed, the protection extends to its curtilage, so even a new boundary wall needed its own listed building consent. It also needed brick piers and foundations designed around the mature trees on the plot, and an agreement with the neighbour whose garden land had been bought. None of that is unusual work in isolation. On a protected building it all becomes a heritage matter, because the council will treat it as one.

The orangery was more delicate again. Adding a garden room to the back of a listed Regency house means opening the wall between the existing room and the new space, and that is where historic fabric is lost. An opening too wide, or a material out of character, could have drawn an objection and turned a straightforward domestic project into a refusal.

The conservation authority asked that the new opening be kept to double-door width, so that less original fabric was removed and the change stayed reversible. We refined the design to suit and made the heritage case for it, aligning the opening with the doors of the orangery itself. Consent followed. The wall was granted in April 2024 and built over the summer; the orangery and the internal alterations were granted that December. The garden is enclosed and in use, and the consent for a brighter ground floor is in hand for the owners to build out.

What we did

Three applications, back to back.

One practice designed both phases and ran both consents on the same protected house, so the heritage argument stayed consistent across them.

The wall

We started at the boundary.

Scheme
A reclaimed-brick wall with piers, an extended outbuilding and a new pedestrian access
Technical
A topographical survey, and structural piers and foundations designed around mature trees
Neighbour
Notice served on the adjoining owner as part of the application
Outcome
Consent granted April 2024, the materials condition discharged, and the wall built that summer

Reclaimed brick, coping and a timber door, all secured by condition and signed off.

The orangery

Then we opened up the house.

Room
A single-storey glazed garden room of about 8.5 sqm off the music room, with a roof lantern
Inside
A new ground-floor WC, and the cellar stair re-handed and re-accessed from the dining room
Applications
A householder application and a listed building application, prepared and run together
Outcome
Both granted December 2024, and the owners are taking the build forward themselves

Traditionally detailed, so a new room reads quietly against a Regency rear elevation.

The heritage case

We argued it on the fabric.

Statements
We wrote the Heritage Statement for each phase and made the case to the authority
The opening
Kept to double-door width, so less original fabric is lost and the change stays reversible
Materials
Reclaimed brick and traditional detailing, taken from the house rather than added to it
The street
The front elevation untouched, so the terrace and its neighbours see no change at all

The conservation authority was on side at each step, and neither application drew an objection.
