Planning Permission Received - Battlescombe Farm

We are delighted to have receieved planning permission recently for a proposal at Battlescombe Farm in the Cotswolds.

The original property is a set of Grade II Listed residential buildings. The living spaces are disjointed and the family requires a set of larger, contemporary kitchen and dining areas which flow better between the different volumes of Cotswold stone buildings. The concept image below shows the proposal, designed with corten steel roof profiles, natural timber cladding and large glass sliding doors to flood the spaces with natural light.

The original buildings feature a large patio space as shown below, which will be infilled by the proposed works, which will complement the materials and proportions of the original historic property.

Progress on Site - Millhouse

Great progress on site at our contemporary extension and renovation project to a Listed Cotswold stone Millhouse in Stroud.

A rhythm of tall elegant glazed windows are framed by deep timber fins, crafted with an Accoya structure, a highly durable processed timber. These windows provide deep sills both internally and externally at the perfect height to perch on, as informal seating additions to the living spaces.

This project will provide a new light filled kitchen, dining and sheltered al fresco seating options overlooking the trees and stream running through the garden.

Progress on Site - St Mary's

Exciting developments on our contemporary extension and renovation works at St Mary’s in Brownshill, Stroud.

The new built elements replace a small, dark kitchen which was unfit for purpose. The new spaces provide generous open-plan living, kitchen and dining spaces which better serve the original house and orientation to the gardens. The spaces open out with views and sliding glass doors on three sides, allowing direct connections to the flowerbeds, lawns and trees with spectacular views down the hillside. Vast glazed doors on two sides roll back to provide a fully open corner and south facing side of the building. This leads on to the patio for al fresco dining during summer months. The roof and walls have been constructed so far and we can’t wait to see this project develop through the next stages.

Planning Permission Granted - Parkfield House

Planning permission received for an exciting new extension to a Grade-II Listed cottage in Chalford, near Stroud. The design will provide a large glazed extension built into the hillside, offering uninterrupted views across the valley.

The existing cottage will be renovated and repaired to restore its traditional charm and character, complemented by the contemporary extension to create an exciting mix of old and new. The original cottage was recently listed by Historic England, resulting in an eyecatching design which conceals the extension from view to preserve the setting to the cottage, while also maximising natural daylight and providing beautiful views across France Lynch, Chalford.

Pre-Application discussions with Stroud District Council helped shape and develop the design. A new partially subterranean garage will hide vehicles from view and preserve the picturesque setting to the cottage. The extension and garage will both have a green roof, blending into the surrounding field. High performance windows and doors combine with natural Cotswold stone to provide an exciting new open plan living space which connects through to the original cottage. The cottage retains its traditional proportions and features, while renovations throughout will provide a comfortable and restored traditional Cotswold cottage. 

Gransmore Architects project featured as 'Property of the Week'

Gransmore Architects’ project, The Ferns, has been featured as ‘Property of the Week’ by Stroud Times. It also featured in Celebrity Escape to the Country, under consideration by Chesney Hawks!

The property is described as a desirable property in the Chalford area: ‘Tucked away in the heart of Chalford Hill, The Ferns is a striking five-bedroom detached Cotswold stone residence that beautifully blends historic charm with modern living.’

Gransmore Architects completed an extension and full renovation of the property. The extension provides a generous light filled living space which has transformed the property, allowing people to enjoy the quintessentially cosy English garden.

Timbercombe Cottage is a Grade II Listed building, nestled in a picturesque valley of Stroud which was faithfully rebuilt from ruins. The cottage was fully retrofitted in the process and a contemporary timber extension was added to the rear.

The retrofit used natural materials throughout, insulating the internal face of every wall with breathable wood fibre insulation and textured lime plaster. Photo-voltaics disguised as natural roof slates on the south facing elevation provide electricity for the cottage whilst working with the parameters of the Listed building planning requirements. The extension is fully clad in larch grown on site.

Please see our project page and instagram for further details.

Works have started on site at Millhouse, a project to extend and renovate a Listed Cotswold stone mill building.

The new built elements will provide a new kitchen dining space with deep overhanging cantilevered eaves to provide sheltered outdoor space adjacent to the river running through the garden. This overhang provides both shade and shelter during adverse weather and facilitates al fresco dinging during warmer months.

Rows of elegant tall windows are framed by beautiful timber fins which extend up to the ceiling, inside and out. A deep window sill also provides opportunity for in-built perch seating.

Edgeworth House - Planning Permission Granted

SOUTH & WEST ELEVATIONS WITH MATERIAL EXAMPLE SWATCHES

We’re delighted to have achieved planning permission for Edgeworth House. The property will create a new family home complete with outbuildings and multigenerational living areas for family members.

Built on the site of an existing property, the design utilises the existing structure where possible, over-cladding with external wall insulation and new facade materials. Newly built living spaces and roof forms create an entirely new architectural approach to the property which sits on a visually prominent hillside site, at the edge of the beautiful historic village of Edgeworth.

Edgeworth village has a distinctive architectural style of traditional Cotswold stone vernacular buildings with elegant sharp gables, chamfered stone window frames and bold gutter details. The new design will create a home which complements the local style, whilst incorporating crisp contemporary detailing to create a new multi-generational home fit for 21stC living.

We are very excited to see how this project can set an example for high quality contemporary interpretations of a traditional vernacular.

Nodlings House - Works Started on Site and New Visualisation Imagery

Works have begun on site for our project, Nodlings House, which recently gained planning permission after a lengthy and successful engagement process with the local authority. The proposal creates a series of sensitive new build elements adjoining a historic stone cottage, which will be retrofitted internally for vastly improved insulation and building performance.

The contemporary forms take reference from the original cottage volume in design and materiality. Opportunities are also taken for new double height spaces, glazed links to draw light deep into the floorplans and large sliding openings to connect internal living spaces to the landscape beyond. The old building had turned its back on the impressive views and southern light - this new scheme now allows all living and bedroom spaces to face south and fully appreciate the opportunities of the site and its spectacular setting. Circulation spaces have been moved to the rear North side, allowing open plan living and dining spaces to flow into the garden with al fresco dining.

We have also recently been experimenting with a new visualisation software to represent our 3D CAD models. Taking a soft, impressionist approach to the 3D view allows a simple interpretation of the proposal at planning stages; this conveys the scale, materiality and atmosphere of the new dwelling in its Autumnal landscape setting to help understand the design proposals alongside the CAD drawing packages.

Quarry Cottage - Award Winning News!

Quarry House, Chalford, recently won Gold in the National Building and Construction Awards 2025, in the category of Best Contractor up to £5M.

Eleven Builders completed the technically challenging construction project with great efficiency and an exceptional attention to detail. The build required a highly coordinated approach, bringing a range of materials together to create a crisply detailed, elegant and contemporary project.

Works included an extension and internal renovations to a traditional Cotswold cottage. The project added a new entrance hallway and feature staircase with curved glass balustrade and a suspended landing. Natural zinc is formed around a unique curved structure at ground level, with elegant radially placed windows at first floor, all topped with a zinc clad conical roof. Internally the extension creates a double height atrium to the stairs, which is delicately suspended from the roof.

Please see our project page for more photographs and read about it in the local press.

Planning Permission Granted - Nodlings House

We are delighted to have received planning permission for Nodlings, a four bedroom property with connected ancillary and garage volumes in Stroud.

The proposals work with an existing historic stone cottage in the landscape, adding new gabled volumes around it to create a new contemporary family property.

Energy conservation and generation is a key principle in the project, creating a highly insulated new home with solar panels on all south facing rooves. Cotswold stone and zinc metal cladding roots the building to its rural industrial context, complementing the original stone cottage and barns whilst providing crisp contemporary interpretions with the new volumes. These are separated from historic stone volumes with elegant glazed links and zinc detailing. This also allows light to flood deep into the floorplans, illuminating stairwells and double height spaces above the kitchen for example.

The original cottage volume will also be retrofitted with internal wall insulation to provide a property which retains its historic charm whilst serving as a warm, comfortable home fit for 21stC living. Scale models and 3D studies served as a key tool for conveying the design throughout the planning process. It required careful and extensive consultation with the local authority to achieve permission for a design which satisfies all requirements of the brief and local policy.

Approaching Completion - Kingston House

Works are approaching completion on Kingston House in Leonard Stanley near Stroud, providing a new-build contemporary single storey home for our client.

Natural Cotswold stone combines combines with Larch timber cladding and a roughcast textured stone render to provide a beautiful new multi generational home. Large vaulted spaces are created inside to provide a spacious and daylight filled home. Two opening central rooflights bring daylight into the centre of the kitchen / dining space, while also helping to ventilate the property.

Solar panels provide electricity to the house, while also heating hot water and charging the car. This combines with an Air Source Heat Pump which connects to the underfloor heating throughout the property. Highly insulated throughout, Kingston House will provide a comfortable and exciting new home for our client.

Progress on Site - Downs Cottages

Works are progressing on the renovation of 4 Downs Cottages, a three storey traditional Cotswold cottage in Frampton Mansell, near Cirencester and Stroud.

The remodel will renovate the property throughout, including a new open plan kitchen / dining space, together with a living room, two bedrooms, bathroom, cloakroom and utility. A new traditional dormer will provide much needed daylight to the bedrooms, accompanied by a Conservation style rooflight. The works will restore the former worker's cottage to provide a comfortable new family home.

Planning Permission Granted - France Cottage, Chalford

Planning permission has been granted for an extension to a Grade-II Listed traditional Cotswold cottage in the Chalford Conservation Area, Stroud.

Pre-Application consultation with the Local Authority Conservation Officer helped to develop the design of the extension, carefully positioned to the rear of the house and largely screened from view.

The new extension will add essential living space to the cottage, to support multi generational living, providing two new bedrooms and an ensuite. Timber cladding and a natural zinc roof contrast the original stone of the cottage. As natural materials they will weather and soften in appearance to complement the Cotswold stone of the cottage. A feature bay window also provides an elevated view across the Golden Valley to the south. Solar panels are concealed within the valley of the property, providing electricity to the cottage.

Progress on Site - Heath Cottage, Amberley

Works are progressing on site with the full remodel of Heath Cottage in Amberley, Stroud. The original Cotswold cottage is restored and extended to create a double gabled Cotswold property.

A feature zinc roof covers the single storey extension, which has a trapezoidal roof with an accompanying rooflight to bring natural daylight into the new kitchen / dining space. The two Cotswold stone gables are joined by a glazed link which creates the corridor at first floor. Hidden on the flat roof another rooflight draws daylight deep into the centre of the property. 

Planning Permission Granted - Dorval House, Sapperton, Cirencester

Planning Permission has been granted for a substantial extension to Dorval House, Sapperton, near Cirencester, to provide a stunning new gallery and entrance hall. The design also includes carefully considered alterations to the existing property to provide a new utility, larder and cloakroom, together with a feature glazed corner to enjoy the picturesque views across the Golden Valley.

Dorval House is set within a secluded and stunning location to the north of Sapperton. The new extension combines natural Cotswold stone and slates, a feature bay window, and natural metal seamed roof to provide a double height living space with ridge rooflights adding daylight from above. The design is carefully formed to the rear of the property preserving the balance and proportions of the original house which dates from 1818. The extension is sympathetic to the original house while also offering a new and different type of living space which connects to the surrounding natural landscape. In this way our design sensitivity balances old and new, providing a living space filled with natural daylight to complement the more cosy and intimate spaces within the original house.

Planning Permission Granted - Pen House, Box

Planning permission has been granted to provide a new feature single storey storey extension to a traditional Cotswold cottage within the Box Conservation Area, which borders Minchinhampton Common.

The extension will replace an existing conservatory and provide a modern interpretation of a Cotswold Orangery. A glazed corner opens the new garden room to the southern views across Nailsworth. Stone and timber combine with a green roof to provide a design which is sympathetic to the original house.

A number of internal alterations improve the flow through to the house, connecting the property with the garden and the views beyond.

Planning Permission Granted - Mill House, Paganhill, Stroud

Planning permission has been granted for an extension and renovation works to a Grade II Listed 18thCentury Cotswold home. The design features a mono-pitched zinc roof, with elegant framed windows and doors which subtly reference the proportions of the original house.

The design is a contemporary interpretation of a Victorian orangery, offering a carefully considered approach to the conservation of the building and its heritage as a working water mill.

The extension is filled with natural daylight, providing direct access and views to the garden and surrounding treescape. Rooflights bring additional daylight into the new kitchen dining space, drawing light further in to the depth of the house.

Planning Permission Granted - St Mary's, Brownshill, Chalford, Stroud

Planning permission has been granted for a kitchen dining extension to a traditional Cotswold property in Chalford. The property is within the Brownshill Conservation Area and the design is carefully formed on the site to respect the proportions and appearance of the original house.

A glass to glass corner opens to the garden, providing a fresh, light filled living space which celebrates its settings. The contemporary design complements the traditional features, materiality and proportions of the original house.
