Case study  /  Ashlawn Road, Rugby

Your home, opened to the valley.

A dated house on the edge of Rugby, turned to face its own valley.

The brief

Modern, but not competing with the house.

The owners came to us with a house they meant to keep for good, and a clear ambition: turn a dated, compartmented dwelling on the edge of Rugby into a modern family home that made the most of an unusual asset, open views across the valley from the back of the plot.

Their brief was specific about restraint. They wanted something modern but not too contemporary, a design that would sit comfortably with the existing house rather than compete with it. Not a new build and not a replacement dwelling: an existing home reworked to live better and open up to its setting.

Form
Single-storey side and rear extension, full internal remodel.
Route
Householder planning application.
The planning journey

A protected roost and a design objection, both navigated to consent.

Planning journey: a bat roost was confirmed in spring 2024; three nocturnal surveys ran that summer; the householder application was submitted in September 2024; the planning officer objected to the front windows in November; the windows were reworked over three rounds; planning permission was granted on 18 December 2024; the ecology condition was discharged on 1 April 2025, 23 days ahead of the council's target; and the home is now under construction.

The planning milestones, from the first bat assessment to consent and conditions discharged.

The scheme

What the house was, and what it becomes.

A dated brick house with conservatories, reworked into a single calm move that faces the owners' own land rather than the neighbours.

Before

The house as we found it.

A compartmented plan, two conservatories, and a rear elevation that turned its back on the best view on the plot.

Black and white photograph of the existing house before the works: a two-storey brick dwelling with a first-floor balcony and two conservatories across the rear elevation, with lawn and mature trees around it
Proposal

The same house, opened up.

The dated rear elevation gives way to a low glazed extension running the width of the garden front. Visualisation of the consented design.

Site plan

Angled off the boundary, open to the valley.

The rear vehicle access, closed off by the earliest concept, is kept clear in the consented layout.

Floor plans

A courtyard through the middle.

An internal courtyard brings daylight into the middle of what had been a long, narrow plan.

The opportunity

Two obstacles. One application.

A bat roost in the roof. An objection to the windows.

Either could have cost a refusal and a resubmission. Surveys confirmed a brown long-eared bat using the roof, so the work could not lawfully proceed without a Natural England licence. The officer then objected to the replacement front windows. Both were resolved inside the same application, and consent was granted in December 2024.

Discuss your project
Rickett Architects study of the proposed rear elevation at Ashlawn Road, Rugby, drawn as a pale massing model: the low single-storey extension running across the garden front of the retained two-storey house, with glazing opening to the lawn

Three fixed constraints on one plot: a protected species in the roof, a close boundary with the nearest neighbour, and the only vehicle access to the rear running down one side of the house.

The full story

Two things made this more than a routine extension. The first was the setting. The plot sits in a countryside location on the edge of town, alongside a small group of neighbouring homes, with the only vehicle access to the rear running down one side. The earliest concept opened up the rear beautifully but closed off that access, and the owners caught it straight away. A close boundary with the nearest neighbour also limited how far any rear element could project. The design had to reach for the view without overstepping the plot's real limits.

The second was a protected species. An initial roost assessment of the existing house found a high likelihood of bats, which triggered a full sequence of nocturnal emergence surveys. Those confirmed a brown long-eared bat using the roof as an occasional roost. From that point the work could not lawfully proceed without a European Protected Species Licence from Natural England, and the planning application had to carry a mitigation scheme the county ecologist would accept.

The planning officer supported the scheme in principle: the countryside location, the extension design and the cladding to the subservient elements were all judged acceptable. The objection was to the proposed replacement windows on the front elevation, felt to be out of keeping with the house and its neighbours. Rather than dig in, we treated it as a design conversation. Over three rounds of revised sketches we brought the window proportions back closer to the originals, matched the existing pane pattern, added brick soldier-course detailing, and moved to a black aluminium frame that picked up on a neighbouring property. The objection fell away.

What we did

Concept, consent, and a set that could be built.

We led the project from the first concept sketches to a fully detailed, consented design, and ran the ecology process end to end.

The design

Four moves that made it work.

Orientation
The extension angled so living spaces open down the owners' own land, not towards the neighbours
Access
Reworked so the rear vehicle access stays clear
Daylight
An internal courtyard lighting the centre of a long, narrow plan
Material
Largely the existing red brick, with composite timber-effect cladding on the smaller subservient elements

South-facing glazing was shaded to manage solar gain. The cladding was chosen to avoid the upkeep of real timber.

The ecology route

A protected roost, cleared on the fast route.

Assessment
Preliminary roost assessment found high roosting potential
Surveys
Nocturnal emergence surveys confirmed a brown long-eared bat occasional roost
Mitigation
Bat boxes on retained mature trees, works timed around the roosting calendar
Licence
Natural England licence secured via the accelerated earned-recognition route

We commissioned the surveys, coordinated the mitigation scheme with the county ecologist, and steered the licence down the faster route the owners chose to save time.

Technical delivery

Detailed to be built.

Fabric
Cavity wall build-ups detailed to the target U-value
Scope
RIBA Stages 0 to 4, ending at technical design
