Building forms and adjoining fabric in Morden
Merton’s Upper Morden assessment describes the late-1930s pair at 12a and 14 Green Lane, including a flat-roofed single-storey bay. The account notes an arch through the terrace providing rear-garden access. Its cover records copyright November 2007, rather than an adoption decision.
Preserve the assessment’s approximate dating where applicable. Present access rights and condition need the building’s own evidence.
Existing condition and the evidence for Morden works
For a Morden semi with a lower projecting bay, outline that covering apart from the main house roof. Identify the room below and the outlet or junction mentioned in any leak account. Ask for the date and scope of earlier work to the projection.
Keep interior ceiling treatment with its own date. State where the outer covering can be viewed from the garden or front space, including obstructions that may limit that view.
For a proposal that changes the flat-roofed bay described in the Green Lane example, distinguish enlargement of the bay from work to the principal house wall behind it. Mark the retained opening and the new support arrangement on the proposed section. If the work also changes the floor or external level, show that separately; a plan labelled simply as a bay extension may leave the relationship to the adjoining building unclear.
The pre-works photographs should make the connection between bay, wall and main roof understandable. Include an orientation or drawing reference so an image of a crack or patched junction can be placed later. Record whether the surface was viewed directly, photographed from a distance or described in an older report. Those limits remain relevant even where a recent decoration makes the finishes appear uniform.
If the scheme includes a new opening through the house, provide the structural drawing for that opening in addition to the room layout. A drawing concerned only with the bay covering may not show the loads or support positions needed to understand a separate internal intervention. Keep any change between the architect's layout and the engineer's current scheme identifiable by date and revision.
Planning records and earlier alterations in Morden
Where a Morden terrace has a passage through the building, mark its entrance, exit and the rooms above or beside it. Identify who can open any gates during an agreed visit. Put the route on the current plot plan rather than relying on a historic description of rear access.
Ask the solicitor to examine the title documents for the route’s rights and responsibilities. Attach papers for an enclosure or changed opening to that particular passage. The technical enquiry can then locate the relevant walls and supported rooms without assuming legal access from the building form.
Where the proposed inspection route passes through an arch, explain what lies beyond it and which adjoining surface is to be recorded. A route suitable for a person carrying a camera may differ from a proposed construction route. Keep those arrangements distinct and identify the current contact for each interest; the assessment's historical access description should not be used as a substitute for that enquiry.
For a roof project at another named Morden group, start again with its actual roof form rather than importing the Green Lane bay detail. Show the relevant slope, ridge and connection to the neighbouring structure. If earlier loft work is reported, ask which drawings concern the changed floor and stair, and which concern only reroofing. The present work description should make clear which of those components will change again.
Keep the council assessment's publication date attached to its architectural account. The document can help identify the local example, but the property file must establish subsequent alterations. An undated photograph or a copied plan should be labelled as such in the evidence list until its relationship to the present building is established.
Access, drawings and the Morden instruction
Show the hip, ridge and adjoining covering on the available roof drawing. Match an invoice to the slope, tile work or rainwater component it names.
If the loft layout has changed, request the stair and roof-alteration plans separately from decoration records. Identify which void can be entered from the home and whether another contact is needed.
A Morden proposal should distinguish the particular Green Lane house or Rhodes Moorhouse Court range before using the local examples. The assessment records different roofs and arrangements, and its estimated date for one group should retain that qualification. Show the actual structural intervention, adjoining accommodation and relevant external levels on current drawings.
For work beside a flat-roofed bay, keep that covering and support separately named from the main roof. A repair schedule for the upper hipped slopes may leave the bay outside its scope. Identify the junction and accessible surfaces relevant to the condition record, retaining dates for earlier leaks or repairs without assuming they all concern the same component.
Where access follows an arch through a terrace, show the route and current arrangement and identify who can organise the adjoining views. The historical description of garden access does not grant a right of entry or establish permission for construction. Keep property documents, practical arrangements and proposed structural work separately identified so the instruction is based on this address rather than a general estate pattern.
Morden party wall questions
Does the Upper Morden assessment establish an adoption decision?
Its cover records a copyright date of November 2007. Do not turn that into a planning adoption or permission claim; check the present address-specific position separately for the proposed work.
What should a Green Lane bay proposal show?
Locate the flat covering, wall and support being changed, with adjoining rooms or structures identified. Keep the bay’s history and new intervention distinct from work to the main roof.
Can the terrace arch establish access for the works?
Confirm the actual route and relevant property information, with practical inspection arrangements recorded separately. The appraisal’s description does not authorise access to every garden or adjoining surface.
How should hipped-roof repairs be described?
Name the slope, house position and component concerned, with dates and scope for earlier work. A report for one part of a roof group should not be treated as evidence of concealed condition throughout the terrace.
