The Christ's College Library+ scheme: frequently asked questions

Why did residents take Christ's College to the High Court, and what happened?

The Christ's Lane Action Group (CLAG) challenged Cambridge City Council's grant of planning permission for the library scheme by way of judicial review (AC-2025-LON-004656). By an order signed on 6 March 2026 and served on 9 March, Mr Justice Kimblin granted permission to proceed on all four grounds, finding them "strongly arguable". On Tuesday 20 October 2026 the High Court quashed the first permission, 25/02161/FUL, on all four grounds of our claim. The hearing took place in Court 18 at the Royal Courts of Justice, before Mr Justice Kolinsky, in R (Christ's Lane Action Group) v Cambridge City Council, AC-2025-LON-004656, in the Planning Court.

What is Christ's Lane in Cambridge and why does it matter?

Christ's Lane is one of Cambridge's busiest pedestrian routes, used by thousands of people every day. It provides a critical link between Christ's Pieces, the Drummer Street bus station, the historic city core, and the main shopping areas including Lion Yard and Grand Arcade. The Lane has existed in various forms since the 13th century, predating the founding of Christ's College in 1505. It was reopened as a pedestrian-only public highway in 2007 to 2008 and was cited as an inspirational case study in English Heritage's publication Valuing Places: Good Practice in Conservation Areas.

What is Christ's College proposing to build on Christ's Lane?

Christ's College is seeking planning permission to demolish its 1970s library in Bath Court and replace it with a new, much larger library building with social and study spaces. The proposed building rises to over 14 metres along a lane only 6 metres wide, presenting a largely blank, fortress-like wall to the public. The new scheme also includes tall ventilation chimneys projecting from the Christ's Lane frontage. The site lies within the Central Historic Core Conservation Area, adjacent to multiple Grade I listed buildings including the Bodley Library, First Court, and Bath Court.

Did Christ's College fix the errors on which the High Court quashed the first permission?

No. While the first application was still before the High Court, the College resubmitted the same building as application 26/02109/FUL, and the Bursar wrote to all 42 Cambridge City councillors stating the application was unchanged. Errors are repeated, and the very massing Historic England identified as causing heritage harm is presented by the College as a benefit. The Council's report of 28 September 2026 repeats the third error in terms and adds new ones: the ten errors are on The application page.

Where can I find the new Christ's College Library+ planning application?

The resubmitted application (26/02109/FUL) is published on the Greater Cambridge Planning portal. Full documentation, including the court documents, heritage evidence, and a plain-English summary, is available on this website.

What did Historic England say about the Christ's College Library+ scheme?

Historic England formally advised in July 2025 that the building "feels too big, overdominant" in its relationship with Bath Court and the Bodley Library, and that "the increased height towards Christ's Lane feels quite large when seen alongside the relatively modest elevations of the college." Historic England stated that the building was "too large for what is a very domestic setting" and that it would result in harm to the significance of the listed buildings. It strongly encouraged the College to reduce the massing. After revised chimney drawings were submitted, Historic England confirmed in September 2025 that "the overall massing of the building remains unchanged", meaning its concerns about bulk were unresolved. Historic England has since confirmed that this advice applies equally to the resubmitted application (26/02109/FUL): its July 2026 letter records that the proposals "remain unchanged from those previously assessed," so its heritage-harm findings stand.

What did the Victorian Society say about the Christ's College Library+ scheme?

The Victorian Society, a statutory consultee, found the dominant scale of the proposed building harmful to the Grade I listed Bodley Library. Its letter of 22 August 2025 says: "Although the 2016 scheme would not be overtly harmful to the Grade-I Listed Heritage Asset, as the newly proposed scheme has the potential to be, we acknowledge that a structure emphasising light and breathability is preferable to a concrete basement." It suggested a radical reduction in height, "reducing the height by approximately half at each floor". Responding to the resubmitted scheme, 26/02109/FUL, on 6 July 2026, it maintained its objection: "the same submitted scheme cannot improve its level of harm." When the College's planning agent sent the Society a rebuttal on 9 July, the Society replied the same evening, standing by its objection: "Our principal point still stands. Harm is attributed to this scheme, and this has not been mitigated in the resubmitted design." The reply did not appear on the public file until 24 July, two days after the consultation had closed.

What did Cambridge Past, Present & Future say about the resubmitted scheme?

Cambridge Past, Present & Future (CPPF) objected to the resubmitted scheme 26/02109/FUL. In its objection of 9 July 2026, CPPF found "multi-layered harm to highly sensitive designated heritage assets" that "stands in conflict with Policy 61" of the Cambridge Local Plan. It set out three separate breaches: a failure to preserve or enhance the setting of the Grade I Bodley Library; an "inappropriate street profile," with ventilation stacks that would "overwhelm the modest scale of Christ's College's historic streetscape, notably Christ's Lane"; and "unjustified heritage harm," concluding that "the minimal public benefits identified here fail to outweigh these costs." CPPF urges the applicant and Council to negotiate a lower and less bulky design.

Why did independent heritage consultant Alec Forshaw object to the scheme?

Alec Forshaw, a former conservation officer and independent heritage consultant instructed by CLAG, concluded that the proposed building is "a damaging overdevelopment of the site." His appraisal identified heritage harm at four levels: less-than-substantial harm at the upper end of the scale to the Bodley Library; less-than-substantial harm at the middle range to Bath Court; less-than-substantial harm to the Central Historic Core Conservation Area; and harm to historic fabric within the Grade I listed kitchen and Upper Hall. He found that the applicant's claim of improved views of the Bodley Library was a misrepresentation: the increased height of the new building would block or overwhelm the very views it claimed to open up. On 5 October 2026 he answered the Council's report: "No document on the register states a fire requirement for the height of the tower, and no regulation imposes one."

Why is a 14-metre wall on a 6-metre lane such a serious problem?

The proposed building presents a sheer wall of over 14 metres alongside a public lane only 6 metres wide, creating an enclosure ratio of approximately 2.3:1. This far exceeds the ratio of established Cambridge streets such as Trinity Street and Rose Crescent (approximately 1.5:1). The 2002 Joint Planning Brief for the Bradwells Court redevelopment explicitly required that "building heights along Christ's Lane will need to be designed to avoid Christ's Lane becoming canyon-like and oppressive." The 2004 planning approval for Bradwells Court kept the parapet height to a maximum of 11.4 metres precisely to respect the scale of Christ's College's frontage. The current proposal exceeds that limit by over 2.5 metres at pavement level, rising further with the chimneys.

What is wrong with the proposed chimneys on the Christ's Lane frontage?

The scheme includes a series of tall, monolithic ventilation chimneys projecting from the Christ's Lane elevation. Even after the College reduced their height by 900mm, they remain as tall as the Gatehouse towers of Christ's College itself. Independent expert Professor Steve Evans, Director of Research in Industrial Sustainability at the University of Cambridge, confirmed that the chimneys do not need to be as high as proposed to achieve effective passive ventilation. He stated that the building could be transposed downward, starting below ground level, and achieve identical passive ventilation performance, with significantly reduced visual impact on Christ's Lane and the surrounding heritage assets. At the Development Control Forum of 29 July 2026 the Master accepted the point: "That height can begin beneath the ground."

What planning policy breaches does the Christ's College Library+ scheme involve?

The application breaches multiple planning policies, as identified in formal objections by CLAG, planning consultant Roger Hepher (hgh Consulting), and John Preston, former conservation officer for Cambridge City Council. Key failures include: breach of Cambridge Local Plan Policy 10 (failure to enhance the public realm and pedestrian route); Policy 56 (failure to provide human-scaled, comfortable public space); Policy 58 (unreasonable overshadowing and visual domination of the public realm); Policy 60 (tall buildings and the skyline, the proposal breaks the established skyline without justification); Policy 61 (failure to sustain and enhance the significance of Conservation Area heritage assets); and breaches of the Framework's heritage policies: HE4(1)(b), which requires harm to be avoided where that is possible; HE4(2), which requires a clear and convincing justification for harm; HE6(3), on the weight to be given to the conservation of designated heritage assets; and HE6(4), under which harm is weighed against the public benefits resulting from the proposal. The Council's own report finds conflict with Policy 61 and with Policy 10.

How does the 2025 scheme compare to the previously approved 2016 Mather design?

The previously approved 2016 scheme by architect Rick Mather used a basement to accommodate the extra space required, keeping the above-ground building to a human scale. It was modelled to maintain the existing street skyline and was found by the Victorian Society to cause no harm to the Bodley Library. The current 2025 scheme abandons the basement, pushing more mass above ground, resulting in a building that is taller and bulkier in the parts most visible from Christ's Lane and from St Andrews Street. Both independent heritage consultant Alec Forshaw and Historic England confirm that the 2025 scheme involves "greater height and bulk close to the Bodley Library" than the previously consented scheme. The Council's own report of 2016 found that the consented design "would meet the needs of Christ's College".

Will the construction cause economic harm to retailers on Christ's Lane?

Yes. The applicant's own Daylight and Sunlight Study shows that over 25 retail windows along Christ's Lane will suffer reductions in Visual Sky Component exceeding 50%, far beyond BRE standards. For the cafes and restaurants on the Lane, daylight is a policy-protected amenity directly linked to business viability. The applicant's own documents give the construction period as "around 18 months" and as "around two years", with the Lane becoming a construction corridor dominated by scaffolding, welfare units, and service vehicles. The closure of Starbucks on Christ's Lane in 2025 was cited as an early symptom of economic harm. The proposal breaches Local Plan Policy 67 (protection of primary shopping frontages) and the Framework's policy P4(1), under which existing businesses "should not have unreasonable restrictions placed on their current or permitted operation as a result of development being approved after they were established".

What is the status of the new application?

The permission is frozen. On 13 October the Secretary of State directed the Council not to grant permission without her specific authorisation while she considers whether to call the application in. The Planning Casework Unit has told us that the direction has no end date. The identical application had been controversially approved on 7 October (26/02109/FUL). No decision notice has been issued. The register shows the application as "Awaiting decision". On 20 October 2026 the High Court quashed the first approval, 25/02161/FUL, on all four grounds of our claim. Our objection rested on heritage harm identified by Historic England, the Victorian Society, and independent experts; multiple breaches of Cambridge Local Plan policy and the NPPF; the absence of meaningful public benefit to offset that harm; and economic harm to one of Cambridge's busiest pedestrian retail streets. If you would like to support a call in, write to us at residents@christs-lane.com and we will tell you how. Read the direction and the record of the committee.

What happened at the Development Control Forum on 29 July 2026?

A Master laughing at the College's own masterplan, a threat as the chair closed the meeting, and a physics lesson from the floor: the Forum that seventy-five petitioners forced met in the Small Hall of the Guildhall on the morning of 29 July 2026, two hours, on the record and on camera. A Forum exists to consider alternatives, and CLAG presented the College's 2023 masterplan, drawn by MICA: a lower library matching the scale of its setting + a study constellation. The Master offered no rebuttal, only "I give you notice, we will reply in writing." And when he promised "more light pouring into the lane", CLAG's lead petitioner, a physicist, replied from the floor: "The pavement will not be illuminated by a 14 metre high window." That is a taste. Read some highlights from the Forum, then watch the Council's video of the Forum and judge for yourself.

Has the Council decided the resubmitted application?

The permission is frozen. On 13 October the Secretary of State directed the Council not to grant permission without her specific authorisation while she considers whether to call application 26/02109/FUL in. The identical application had been controversially approved on 7 October 2026. We have asked the Secretary of State to call the application in. On Tuesday 20 October 2026 the High Court quashed the first permission, 25/02161/FUL, on all four grounds of our claim.

What is the Secretary of State's direction of 13 October 2026?

It is a holding direction under article 31 of the Town and Country Planning (Development Management Procedure) (England) Order 2015. The Planning Casework Unit issued it on Tuesday 13 October 2026, the day we asked for it. The Council published it on the planning register on 14 October 2026 as document 9554694. It directs the Council "not to grant permission on this application without specific authorisation". It was issued "to enable the Secretary of State to consider whether she should direct under Section 77" of the Town and Country Planning Act 1990 "that the application should be referred to her for determination". It does not prevent the Council from considering the application or refusing it. It is procedural, and it "should not be read as any indication of the Secretary of State's attitude towards the application scheme". Read the direction in full.

What would a call in mean?

If the Secretary of State calls application 26/02109/FUL in under section 77 of the Town and Country Planning Act 1990, she decides it instead of the Council. The Planning Casework Unit has told us that it is "assessing the application against published policy on calling in applications", and that a decision on whether or not to call in an application "is a procedural decision as to who should deal with a planning application". The Secretary of State has not yet decided. Our case for a call in, criterion by criterion, is on The call in page.

What happened at the Planning Committee on 7 October 2026?

The committee voted to approve the identical scheme, 26/02109/FUL, thirteen days before the High Court hearing. Members were told that if the applicant appealed after 16 October the Council would lose the right to determine the application. A motion to defer, proposed and seconded, was never put to the vote.

Members did not have a complete record of our representations

Officers told members they had "a complete record" of our representations. Our letter to the fourteen members of the Committee, sent on 30 September, reached them fifty five hours later, forwarded by the Council's mailbox at 4.44 pm on the Friday; our papers of 25 September were answered in the Amendment Sheet of twenty pages, published on the Monday night, which the Chair gave members ten minutes to read, calling it "only about 10 pages".

The Court was told an order quashes the permission and members that it does not

The Council's own skeleton argument for the hearing, signed the day before, told the Court that an order "quashes the decision granting planning permission on all 4 grounds in the claim"; the report before members said "the Court has not done so". Members were told by the Senior Planning Lawyer that the Council had agreed "a consent order that effectively quashed the planning permission"; no order had quashed the permission at that date (the High Court quashed it on 20 October 2026), and the Chair told the same meeting that the quashing "isn't a decision yet because it hasn't gone to the court".

Members were told the report does not rely on optimum viable use, and it does

They were told by the Delivery Manager that "The current report does not rely upon the concept of optimum viable use in reaching its recommendation"; paragraph 26.25 of the report counts the continued use of the Grade I listed College buildings among the social benefits, with "significant weight", the error the Council conceded in the High Court and the report repeats.

Two officers gave two accounts of the degree of harm

The conservation officer told members that "the balance" of harm and positive effects "is a low level of harm"; the case officer told them: "I set out the level of harm prior to assessing heritage benefits". Two officers gave two accounts of one figure: the conservation officer's comments reach it as a balance, after four positive effects are set against the harm; the report states it before the benefits and gives no reason of its own. No consultee put the harm at "low" before the benefits. The Framework's policy HE5(2)(c) says: "The degree of harm should be identified". The degree before any weighing is on no document. That is the 2025 error again: one figure that is a balance in one officer's account and the harm in the other's. Our speaker told members that the errors the Council conceded in the first decision "have not been corrected. They have recurred." Read the record of the meeting, with the Council's webcast and the documents we placed before members.

What are the ten errors in the Council's report?

Our response to the report and the Amendment Sheet, placed before every member on the morning of 7 October, names ten errors.

The first is that the Council's own skeleton argument describes the report to the Court differently from the report before members. The second is that the continued use of the listed buildings is weighed as a public benefit again, the third ground of the judicial review. The third and fourth are that the harm is neither justified nor avoided: the report calls the stair tower and the scale of the building required where its own paragraphs call both the applicant's choice, and the Amendment Sheet records that the applicant was advised how to avoid the harm and chose to proceed. The fifth is that Historic England's finding of harm from the bulk of the whole building is confined to one stair tower with no reason given.

The sixth is the tall buildings policy declared not engaged on the report's own words. The seventh is that the report never decides whether the proposal accords with the development plan as a whole. The eighth is the shops' daylight, not assessed. The ninth is the temporary building in Second Court, assessed by no one. The tenth is that the report was written before our papers of 25 September reached the Council and the sheet answers them without changing a finding. Each, with the report's words and the document that contradicts them, is on The application page.

What did the High Court decide on 20 October 2026?

The Court quashed the first permission, 25/02161/FUL, on all four grounds of our claim. It also set aside, on our application, its order of 25 August 2026, which had approved the draft consent order we had not signed. What the Court decided is on The hearing page.

What have we asked the Secretary of State for?

On Tuesday 13 October 2026 we asked the Secretary of State for a holding direction and for the application to be called in. The direction was issued that evening. Our case for a call in, against each of the published criteria, is on The call in page.

Who is Christ's Lane Action Group?

A coalition of residents and stakeholders dedicated to safeguarding the heritage, culture and public amenity of Christ's Lane and Cambridge's historic core. We brought the judicial review as residents, without a solicitor, and were represented at the hearing by Emma Dring of Cornerstone Barristers. Our statement of 14 October 2026: "We do not oppose a new library for Christ's College, but this scheme is too big."

What did The Architects' Journal report about the Christ's College Library+ row?

On 29 July 2026 The Architects' Journal took the row national, reporting the judicial review and the court's refusal to let the College hurry it. The College's own planning agent concedes "the material submitted is almost entirely the same". The second application, 26/02109/FUL, "could go before the planning committee in September".
