Located near Penrith in North Cumbria and with projects ranging from small scale, luxury barn conversions to large, opulent new builds, CDB are consistent in their pursuit of high quality, sustainable and contextually sensitive architecture.

Supported by a team of 35 highly skilled designers and craftsmen Malcolm Iredale, provides an exclusive level of expertise with regards to the appraisal and alteration of historic buildings and the production of architecturally honest, visually stimulating new builds.                

Whilst CDB hold great value in the conservation and celebration of heritage assets they are certainly not shy of incorporating cutting edge materials and technologies into their designs. Indeed, sustainable technologies are one of the hallmarks of the CDB design approach with modern materials regularly and gainfully employed, often serving to contrast spectacularly with more traditional building elements.

The environmental impact of building design is under constant review at CDB, who lead by example by powering their offices and selected business vehicles using an on-site wind turbine. CDB also have operational biomass boilers, turf roofs and air source heat pumps at their offices, which provides the clients with the opportunity to see and understand the key technologies suitable to their designs.

Energy efficient solutions are investigated at every stage of the design process with clients opting for a range of environmental strategies. Successful design solutions have also included solar/PV technologies, solar gain/thermal massing configurations, inventive building fabrics and locally sourced, salvaged materials.

Along with their ecological credentials, what sets CDB apart from its competitors is the wealth of knowledge and expertise provided to its clients. This level of service ensures that their designs uphold the highest standards of integrity, provides a sure platform upon which they can execute their unquestionable flare for design and live up to their staff motto "Right, first time" - Crafting Cumbria’s Heritage.


Refurbishment of existing listed house and conversion of listed barn...


Carrock D&B have done a fantastic job for us renovating our Grade 2 listed house and converting the adjacent barn. They came up with aesthetically pleasing and innovative solutions to the challenge of an old and semi-derelict building. Their attention to detail and quality of the building work was second to none.

Case Studies

Listed Barn Conversion with Link Extension to 18th Century Farmhouse


FMB REGIONAL AWARD WINNER - 2015 Small Renovation Category

The purpose of this design was to provide the clients with a studio workshop and additional living space. This was achieved by way of a new, single story link between the existing, listed farmhouse and a neighbouring stone barn which was converted.
As the main house is Grade II listed, Carrock were mindful that any alterations or additions to the existing property or the barn within its curtilage were to be sympathetic, low profile and subservient in scale to the existing structures.
The link building was required to be of a scale sufficient enough to provide a spacious sun room and a new biomass boiler serving the adjoining buildings. 
Whilst alterations to the external appearance of the properties are wilfully poised and discrete, the internal space provide its users with a series of characterful living spaces. Arguably the most dramatic of these spaces is the link building which features three animated curved Green Oak blades as part of its dynamic roof structure.  
At first floor level, the necessary raised collar roof truss was beyond the structural engineers limits for a traditionally jointed truss and so Carrock designed and manufactured a flitched steel plate truss which was then clad in 15mm thick Oak. Attention to detail when designing these structural elements avoided the need for unsightly exposed steelwork and ensured the original personality of the property was retained.
The site benefits from attractive rural views which are harnessed by a bespoke Oak bi-fold screens. These screens were designed in order allow the sunroom windows to be fully folded back. This opens the space to the elements, maximising the user experience and encouraging healthy natural light and air movement.
Our clients also commissioned a biomass boiler and wood pellet store. These facilities were successfully introduced within the very tight plan by concealing the boiler behind a curved sound proof wall. This energy efficient boiler now serves the whole main building and extension and replaced an old oil burning boiler.
The finished link extension and barn conversion unites these properties in a seamless and respectful manner. The result is a cohesive property with immense charm which provides the clients with a comfortable, bright and modern space to enjoy throughout the year.
Again this project demonstrates Carrock’s philosophy of “ Right first time “ - Crafting Cumbria’s Heritage.

New Build House in Conservation Area


FMB REGIONAL AWARD WINNER - 2015 New Home Category

Presented with a secluded sloping site in a conservation area in the South West coast of Cumbria. Carrock Design Build were commissioned to design & Build a large executive home where the highest quality of finish was to be achieved.

Planning and conservation area consent took many months of detailed negotiations due to the very tight nature of the site with many trees having TPO’s. The arboricultural report severely restricted site operations and tree protection zones were enforced throughout.

The brief for a five bedroom house with garage; gymnasium and cellar meant constructing a basement to comply with a planning ridge height restriction. The necessary excavations were in hard bedrock and on two separate occasions, these excavations were flooded via the bedrock fissures and the depth of water took two days to pump dry. The depth of dig along one edge of the site meant digging up to two storeys below the adjacent higher building plot and meant health & safety procedures on-site were strictly controlled and good relationship forged with our neighbours.

The space available for site operations was critical throughout with limited parking and space for logistics. A ‘just in time’ methodology was employed with deliveries often arriving to site on the day they were required. Stacked site cabins were used and located on the spare ground within the tree protection zones.

With excavations complete, a stepped reinforced raft foundation was cast and a specialist RIW tanking system commissioned. A heavy reinforced concrete & block retaining wall was built. On a heavily sloping site, we encountered very shallow mains services that had to be deepened. Formation of levels around the building were critical with the sloping driveway intersecting the adjacent sloping access drive and the split level building. Great care had to be taken with the tanking details to ensure the building remains watertight.

Innovative access arrangements were employed to service and allow fuel deliveries to the biomass boiler located in the cellar. This boiler is linked to the AV control system allowing our clients to control and monitor the building from anywhere in the world.

Our client worked abroad during the build and placed a great deal of trust in Carrock Design Build to project manage the job efficiently. We relied heavily on Email communications and occasional site visits when back in the UK.

At all stages of the build, attention to detail was paramount. Throughout the build, our client requested many changes to the design that were enthusiastically incorporated by Carrock Design Build. Some of these requests included a full height mirror wall in the gymnasium or 6'6" interior door heights or bespoke bi-fold Oak garage doors. Even a shadow bead detail to ‘float’ the ceiling plaster 3mm off the adjacent wall plaster.

With a planning restricted ridge height, the building uses a semi ‘room in roof’ design along with exposed local sandstone features and window surrounds and local slate roof completing the highest quality executive home feel. Extensive multi level external works with stone retaining walls completes the build.

Our clients occupied their new home in March 2014 and since then, we are proud to say that no snagging or rework has been required on this build. Not a plaster crack or nail pop. This fact alone vindicates the Carrock philosophy of " Right first time " - Crafting Cumbria’s Heritage.
