Structural building plans in Islington
Structural building plans for an Islington home are not the planning drawings: they are the calculations and marked-up plans that show how each new beam, steel or opening is supported, and they go to Building Control. DrawingsDirect's structural calculations start from £745, for a single beam or opening.

Structural plans and building regulations plans are not the same sheet
People searching for structural building plans in London usually mean the engineering part of a Building Regulations submission. It sits beside the construction drawings, which cover insulation, drainage and fire safety, and it answers a narrower question: what holds this up.
Our Building Regulations drawings service prepares the wider package, and the structural calculations explained guide shows where the structural set fits inside it.
Islington's planning record
Islington made 337 householder decisions over the four quarters 2025 Q3 to 2026 Q2, counting prior approvals, and 93% were granted. Excluding prior approvals, 97% were decided within 8 weeks (our analysis of MHCLG planning application statistics, table PS2).
Of 180 householder appeals decided between 2021 and 2026, 25% were allowed (our analysis of the Planning Inspectorate Casework Database, release 2609). That is a record of the past, not a forecast.
The national register holds 41 conservation-area entries for Islington (our analysis of the MHCLG Planning Data Platform conservation-area dataset, snapshot retrieved 14 Aug 2026), so check the council's conservation area map for your street. See planning permission in Islington for the application side.

Shared walls and notice periods
Where a new beam bears into a wall shared with next door, a party structure notice is served at least two months before the proposed work begins (Party Wall etc. Act 1996, section 3(2)(a)). Read it on legislation.gov.uk, or see the party wall agreement guide.
The Building Control side runs on its own clock: the authority must notify the outcome of a full plans application within five weeks of receipt, or a longer period agreed in writing (Building Regulations 2010, regulation 14A(6)).
Fixed fee for the calculations
Structural calculations for a single beam or opening start from £745. Several beams or a new floor are priced as a job; the pricing page lists our other fixed fees. Building Control charges its own fee.
