Listed building consent drawings for Darley Abbey — measured as existing, proposed in the same detail, and supported by a heritage statement that answers Derby City Council's conservation officer on the terms the 1990 Act actually sets.
Derby City Council granted 93% of the householder planning decisions it made in its latest published year — 6 points above the 87% England-wide householder average. Darley Abbey lies within the Derwent Valley Mills World Heritage Site, so alterations are tested against WHS Outstanding Universal Value and its setting, not ordinary householder policy alone, which is where a policy-literate drawing pack earns its keep. Its dominant Georgian (1714–1837), Victorian (1837–1901) and interwar (1918–1939) housing stock sets the design brief on most streets.
Before permission is required, Class B allows 40m³ of added loft volume on a terrace and 50m³ on a semi or detached house, and Class A allows a 3m single-storey rear extension on a terrace or 4m on a detached house. In conservation areas such as Darley Abbey, Allestree and Strutts Park those rights are removed, so we confirm your exact address before a line is drawn. A validated householder application in Darley Abbey is determined against an 8-week statutory target.
Darley Abbey village (the most complete 18th-century mill village in the world, built around the Boar's Head Mills), Darley Abbey Mills (the restored Evans cotton-mill complex, now workspace and event venues, dating 1782-1830), Darley Park (riverside parkland and larger houses on the west bank of the Derwent), Old Lane (terraced and detached mill-era cottages climbing from the river), Abbey Lane (the historic approach past St Matthew's Church) and Broadway (interwar and later houses on the northern edge of the village) — these are the Darley Abbey pockets our drawings cover most. Heritage designations here include Darley Abbey, Allestree and Strutts Park. Derby City Council weighs each proposal against the Derby City Local Plan Part 1 (Core Strategy) and Part 2, where the village holds a dense concentration of listed mill and cottage buildings, so many works need listed building consent alongside planning permission. On roofs the borough is steep gabled roofs on the Georgian mill cottages and pitched roofs on the later village houses, over late-18th and early-19th-century mill-workers' housing built by the Evans family, the Boar's Head cotton mill complex and associated buildings and later Victorian and interwar houses on the village fringe.
Listing protects the whole building, not the front elevation. Removing a partition, replacing a staircase balustrade, changing a floor finish, or lining a wall with insulation are all alterations to special interest, and all can require consent. That surprises owners far more often than the external rules do — and it is why the first deliverable on a listed project is an accurate record of what is there, not a proposal for what replaces it.
Darley Abbey sits within an area of late-18th and early-19th-century mill-workers' housing built by the Evans family, the Boar's Head cotton mill complex and associated buildings and later Victorian and interwar houses on the village fringe, and its designated heritage includes Darley Abbey, Allestree and Strutts Park. Conservation-area designation and listing are different things and frequently overlap: a listed house inside a conservation area needs consent for internal work under the listing, and is judged on its contribution to the wider area under the designation. We establish both before proposing anything.
Section 16(2) of the 1990 Act requires Derby City Council to have special regard to the desirability of preserving the building, its setting and any features of special architectural or historic interest. In practice that means the drawings must show what is being lost as clearly as what is being gained, and the case for the intervention must be made on heritage terms rather than on convenience.
Consent from Derby City Council is required for works affecting special interest. That commonly includes:
We survey the building as existing at a level of detail that lets a conservation officer see the fabric, then draw the proposal in the same detail alongside a heritage statement — so the decision is made on evidence rather than on assumption.
Below is Derby City Council's real decision record, drawn from official planning statistics and refreshed as new data lands. Derby approves most applications it determines, but in Darley Abbey World Heritage Site status, listed mill-village buildings and conservation detail make design and heritage justification the decisive factors. Listed applications are decided on the quality of the record and the justification, which is where most refusals actually originate.

Across Darley Abbey village, Darley Abbey Mills and Darley Park, the schemes that get consent tend to be reversible, legible and honest: new work that reads as new rather than as imitation, services routed in existing chases rather than cut into original fabric, and interventions concentrated in later or lower-significance parts of the building. Rear additions in a contemporary idiom are often accepted where a pastiche extension is refused.
Darley Abbey lies within the Derwent Valley Mills World Heritage Site, so alterations are tested against WHS Outstanding Universal Value and its setting, not ordinary householder policy alone. Where planning permission is needed as well — for an extension, say — the two applications run in parallel and are usually determined together. We prepare them as a single coordinated set so the heritage case and the planning case do not contradict each other, which is a surprisingly common reason for a refusal on an otherwise sound scheme.
We prepare listed building consent packs across Darley Abbey. A few of the areas where heritage work comes up most often:
Listed building consent drawings for Darley Abbey village — the most complete 18th-century mill village in the world, built around the Boar's Head Mills — surveyed as existing and drawn to the detail Derby City Council's conservation officer needs.
Listed building consent drawings for Darley Abbey Mills — the restored Evans cotton-mill complex, now workspace and event venues, dating 1782-1830 — surveyed as existing and drawn to the detail Derby City Council's conservation officer needs.
Listed building consent drawings for Darley Park — riverside parkland and larger houses on the west bank of the Derwent — surveyed as existing and drawn to the detail Derby City Council's conservation officer needs.
Listed building consent drawings for Old Lane — terraced and detached mill-era cottages climbing from the river — surveyed as existing and drawn to the detail Derby City Council's conservation officer needs.
Listed building consent drawings for Abbey Lane — the historic approach past St Matthew's Church — surveyed as existing and drawn to the detail Derby City Council's conservation officer needs.
Listed building consent drawings for Broadway — interwar and later houses on the northern edge of the village — surveyed as existing and drawn to the detail Derby City Council's conservation officer needs.
They are separate consents with different tests, and many projects need both.
| Consent | What it covers | Fee | Consequence of proceeding without it |
|---|---|---|---|
| Listed building consent | Works affecting special interest, internal and external | None | Criminal offence under section 9 of the 1990 Act |
| Planning permission | Development — extensions, outbuildings, use changes | Payable | Enforcement action; may become immune after 10 years |
| Conservation area consent context | Demolition and character in a designated area | Varies | Enforcement; prosecution for unauthorised demolition |
| Building regulations | Structure, fire, insulation, ventilation | Payable | Enforcement notice; problems on sale |

A process built around what a conservation officer actually assesses.
Send us the address and the listing entry. We confirm grade, what the listing covers, whether curtilage structures are caught, and how Derby City Council has treated comparable schemes.
We survey as existing in real detail — plans, elevations, sections and the features that carry the significance — because a proposal cannot be assessed against a record that does not exist.
We draw the proposal in matching detail and write the heritage statement that identifies significance, impact and justification in the terms section 16(2) requires.
We submit to Derby City Council, engage with the conservation officer, and revise the drawings free until the decision is issued.
Frequently, yes. Listing covers the whole building, so removing a partition, altering a staircase, replacing joinery or re-plastering historic surfaces can all require consent from Derby City Council. There is no internal exemption and no size threshold. The safe route is to establish what is significant before work is designed, which is what the measured survey is for. This applies to your Darley Abbey address specifically.
Carrying out unauthorised works to a listed building is a criminal offence under section 9 of the Planning (Listed Buildings and Conservation Areas) Act 1990, and it does not become lawful with the passage of time the way some planning breaches do. Derby City Council can require reinstatement. Where work has already happened, an application for retrospective consent is usually the right first step, and we can advise on it. This applies to your Darley Abbey address specifically.
No. Listed building consent applications carry no application fee, which sometimes leads owners to assume the process is lighter than a planning application. It is not — the evidence expected is greater, because the decision rests on the effect on special interest rather than on amenity, and an under-documented submission is the most common cause of delay. This applies to your Darley Abbey address specifically. Derby City Council is the decision-maker.
If the work is also development — an extension, an outbuilding, a change of use — then yes, and the two applications run in parallel to Derby City Council. Internal alterations usually need only listed building consent. Where both are required we prepare them as one coordinated set, because inconsistencies between the two submissions are a recurring reason for delay. This applies to your Darley Abbey address specifically.
Sometimes, but rarely with modern units. Historic windows are often the single most significant surviving feature, and replacement is judged on the condition of the existing joinery and the accuracy of what replaces it — glazing bar profile, glass type, opening method and reveal depth all matter. Repair and secondary glazing are usually the route that gains consent, particularly inside designated areas such as Darley Abbey and Allestree. Derby City Council is the decision-maker.
The statutory target is eight weeks from validation for most applications, and thirteen for larger schemes. In practice the timetable is set by how complete the submission is: a conservation officer who has to ask what the existing fabric looks like will take longer than one who can see it. We submit a record that answers those questions upfront. This applies to your Darley Abbey address specifically. Derby City Council is the decision-maker.
