In Newham — Victorian terraces across West Ham for the most part — a loft conversion drawings package is the full measured-survey-to-submission drawing set London Borough of Newham needs in order to determine an application: existing and proposed plans, elevations and sections at 1:100 and 1:50, a location and site plan, and the supporting statements the case officer asks for.

Every Newham postcode district we draw in, the stock that dominates it and the authority that validates a loft conversion there. Newham fees below are the statutory England rates for 2026, not loft conversion estimates.
| Postcode | Area | Dominant stock | What it means for a loft conversion |
|---|---|---|---|
| E6 | East Ham / Beckton | Victorian terraces | A loft conversion at an E6 address in East Ham / Beckton is determined by Newham Council under its own Local Plan policies for East Ham / Beckton. |
| E7 | Forest Gate | Victorian terraces | A loft conversion at an E7 address in Forest Gate is determined by Newham Council under its own Local Plan policies for Forest Gate. |
| E12 | Manor Park | Victorian terraces | A loft conversion in Manor Park may land with Newham Council or Redbridge Council — E12 crosses the boundary, and the E12 policies map decides it street by street. |
| E13 | Plaistow | Victorian terraces, post-war flats | E13 covers Plaistow only; Newham Council handles the loft conversion, and Plaistow case officers apply the E13 conservation-area map. |
| E15 | Stratford / West Ham | New-build, post-war estates | A loft conversion at an E15 address in Stratford / West Ham is determined by Newham Council under its own Local Plan policies for Stratford / West Ham. |
| E16 | Canning Town / Royal Docks | Post-war estates, new-build | A loft conversion at an E16 address in Canning Town / Royal Docks is determined by Newham Council under its own Local Plan policies for Canning Town / Royal Docks. |
| E20 | Olympic Park / East Village | Victorian terraces across West Ham | Olympic Park / East Village sits wholly inside E20, so Newham Council validates every loft conversion submitted from an E20 address. |
Roof pitch, wall build-up and plot depth change every few Newham streets, and each one changes what a loft conversion can achieve at that address.
Newham conservation designations: there are 10 across Newham Council, Forest Gate, Plaistow, West Ham among them. Designation costs a Newham owner the permitted-development route: a loft conversion then needs a £548 householder application over 8 weeks, in place of the £249 prior approval route that takes 6 weeks. West Ham is the Newham designation that most often changes a loft conversion design.
What Article 4 removes near Newham: Article 4 Direction requires planning permission for any HMO conversion, plus restrictions on office-to-residential in Stratford and Royal Docks. Before pricing a loft conversion we check whether the E6 address is inside the mapped area, because Newham Council draws the Newham boundary street by street rather than across the whole of Newham.
The building fabric around Newham: Victorian terraces across West Ham, Forest Gate, Plaistow; Olympic-era new-build in Stratford; post-war in Canning Town; substantial ongoing regeneration. High-regeneration borough; Olympic Park and Royal Docks drive major development; heavily HMO-managed borough. A loft conversion in Newham is scoped against that stock first, because it decides whether the scheme runs as permitted development, a £274 Lawful Development Certificate, or a full £548 application to Newham Council.

Of 56 lawful development certificate appeals decided in Newham over the window covering appeals decided 2016-2026, Newham was upheld more often than most London councils — only 16.1% of appeals succeeded, against 37.5% across London. 9 were allowed and 47 dismissed. Most loft conversions run under permitted development and end in a certificate of lawfulness, not a permission. These 56 are the Newham cases where the council disputed that the work was permitted at all.
Half of those Newham appeals took more than 152 days to decide from the day the appeal started — time added on top of the council's own determination period, which is the argument for getting the application right first. 96.4% were decided by written representations rather than a hearing or inquiry, meaning the written case and the drawings were the whole of the evidence.

Direct answers to the questions Newham homeowners ask every week about loft conversion drawings.
Start a free quote →It depends on your exact address in Newham. Most standard loft conversions qualify as Permitted Development (no planning permission needed) if under 40m³ for terraced or 50m³ for semi-detached, with matching materials and 20cm eaves setback. However Newham has Article 4 Directions that may remove these rights — and flats, conservation areas and listed buildings always require full planning. We confirm permitted development eligibility at the free feasibility visit.
Two costs matter for a Newham loft: our architectural package (planning route, building regulations and structural calculations, quoted as one fixed figure) and the builder's construction cost, which varies with loft type — a standard dormer is materially cheaper to build than a mansard. We quote the design fee up front; see our fees.
Mansards in Newham are less common historically — Newham Council considers each application on its merits. Rear mansards on suitable terraced or semi-detached properties, matching the roofscape, have a reasonable approval rate with the right design and supporting heritage commentary where relevant.
2.3m measured from existing ceiling joist to existing ridge is the practical minimum for a standard conversion in Newham. Below 2.2m usually requires dropping the ceiling below (reducing rooms on the floor beneath) or redesigning as a mansard.
Most Newham loft conversions trigger Party Wall Act notices — legal notices to all adjoining owners. Rear dormers can also prompt right-to-light considerations in dense terraced streets, particularly in Manor Park. We handle both processes.
Newham's victorian terraces across West Ham, Forest Gate, Plaistow stock lends itself to rear dormers (most common), hip-to-gable (semi-detached), and mansard (period terraces and conservation contexts). Velux-only conversions are possible where ridge height allows. We recommend the best structural and planning route at survey.
We cover all Newham postcodes — E6, E7, E12, E13, E15, E16 — with surveyors based locally. Survey appointments within 3 working days. Our structural engineer is London-based and attends site when required.
Most Newham loft conversions require Party Wall notices to adjoining neighbours — typically for steel beam installation and/or raising the party wall. We can co-ordinate the notice process; our in-house engineer handles the structural element. The Act gives neighbours 14 days to respond.
