Licence to Alter Drawings in Clapham

There is no single Clapham planning label that can safely be copied onto every Licence to Alter pack. Lambeth publishes separate conservation-area profiles for Clapham, Clapham High Street, Clapham Park and Northbourne Road, Clapham Road and other nearby areas. Around Clapham Common, the borough boundary also matters. We therefore begin with the full property address and the councils’ current mapping, not a postcode-level assumption.

For a Lambeth address, the council directs applicants to search the property in its planning database and read the Constraints tab. That check can identify the relevant conservation area and other recorded constraints. It does not reveal the private lease, the demise or a landlord’s alteration procedure, so those documents are obtained separately before the drawing brief is fixed.

Clapham Common illustrates why an address check is essential. The adopted Wandsworth appraisal explains that Lambeth owns and manages the Common while Wandsworth administers roughly half of it for planning, licensing and highways. A view toward the Common does not by itself identify the planning authority or conservation designation for a particular flat; the property must be checked on the relevant council system.

Article 4 controls must also be read precisely. Lambeth’s current heritage register does not establish blanket Article 4 coverage for all of Clapham, and the adopted Clapham Park and Northbourne Road statement expressly records no Article 4 direction within that conservation area. That is not permission for a proposed alteration: the address, building type, ownership and scope still determine which approvals are required.

Lambeth has a separate Class MA Article 4 direction covering mapped parts of Clapham High Street town centre. It concerns specified commercial, business and service uses changing to residential use. We do not present that use-class control as a general restriction on replacing windows, moving a bathroom or opening a wall inside an existing flat.

A flat should not be treated as if it had the same permitted-development rights as a single dwellinghouse. Lambeth’s published guidance limits the householder permitted-development route to houses rather than flats or maisonettes. Wandsworth likewise explains that flats and houses converted into flats do not have permitted-development rights for window and door replacement. The exact external proposal therefore needs its own planning check.

The Licence to Alter question is private. The lease and the current landlord or managing agent procedure determine whether consent is required for structure, services, hard flooring, wet-area relocation, windows, common parts or another part of the proposed work. Council planning pages cannot prove those private terms, and a landlord’s consent cannot grant planning permission, listed building consent or Building Regulations approval.

Council-landlord guidance is useful only when the council is actually the landlord. Lambeth tells its own leaseholders that written consent is required for specified layout and structural changes, doors and windows, communal services, wall removal, boiler flues, loft or basement works, extensions and hard flooring. We label that route “Lambeth Council leaseholder” rather than applying it to a private freeholder elsewhere in Clapham.

Wandsworth’s published route is similarly conditional. It says that, under the vast majority of its 125-year council leases, the council retains the structure and exterior, and that structural alterations and windows require permission normally documented through a licence or deed. That supports a Wandsworth Council landlord pack only after the landlord and lease have been confirmed.

The drawing set is then matched to the verified private process and the works. It may include an existing and proposed demise plan, clearly identified wall changes, sections through relevant floor or ceiling build-ups, drainage routes for a wet-area move, and details of any external window, flue or extract alteration. Structural, fire, acoustic and waterproofing information is commissioned where the actual scope requires it.

Planning and heritage material is added only where the address and work engage it. A visible vent, replacement window or other external change may need assessment against the relevant conservation-area character and planning history. Work affecting a listed building needs a separate listed-building check, including internal fabric where applicable. Neither question can be resolved from the words “Clapham flat” alone.

A reliable sequence is: confirm the address and council constraints; read the lease and named landlord procedure; survey the demise and common-part interfaces; define structural, services, fire and acoustic scope; prepare the private-consent drawings; and coordinate any planning, listed-building and Building Regulations submissions that are genuinely required. This keeps each decision with the authority or party that can actually make it.

Before appointment we ask for the full address, lease and plans attached to it, the landlord or managing agent’s current alteration guide, the proposed works list, photographs and any previous approvals for the same property. Previous decisions are evidence about that building, not automatic consent for a new proposal. Missing documents are recorded as open checks rather than replaced with assumptions about Clapham.
