A construction-ready drawing package compliant with every Approved Document — Part A structure, Part B fire, Part L thermal, Part M accessibility — submitted to LABC or your approved inspector with structural calculations coordinated.
For Haringey homeowners in Edwardian terraces in Crouch End, a building regulations drawings package is the full measured-survey-to-submission drawing set London Borough of Haringey 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.

A construction-ready drawing package compliant with every Approved Document — Part A structure, Part B fire, Part L thermal, Part M accessibility — submitted to LABC or your approved inspector with structural calculations coordinated.
Housing stock in Haringey: Edwardian terraces in Crouch End, Muswell Hill; Victorian two-up-two-downs in Harringay Ladder; 1930s semi-detached in Muswell Hill; post-war in Tottenham.
Character: Muswell Hill and Crouch End have strong conservation coverage with clear loft/mansard precedents; Tottenham generally permissive.
Article 4: Borough-wide Article 4 for HMO conversions.
Everything drawn at 1:50 — plans, sections, elevations — and annotated throughout, so materials and build-ups are specified rather than left for the builder to interpret.
Every element gets a U-value: walls, roof, floor and glazing. SAP or SBEM is run where the project calls for it, and the compliance statement written up to accompany the figures.
Chartered engineer sign-off on beams, pad foundations, lintels, roof structure.
Escape routes, compartmentation, smoke alarms, fire-rated construction detail.
Soil and vent pipe routes, MVHR coordination, EV charging (Part S).
We lodge a Full Plans application, at Haringey's own Building Control department or with a private inspector, then book and chase the inspections until the completion certificate is issued.

Single planning or regs submission.
Planning + building regs + structural.
Listed, conservation, complex sites.

Each Haringey postcode district is set out below with the housing that dominates it and the authority that validates a regulations package at an address there. Fees listed there are 2026 statutory rates for England, owed to the council, and they say nothing about the price of a drawing package.
| Postcode | Area | Dominant stock | What it means for a building regulations package |
|---|---|---|---|
| N4 | Finsbury Park / Stroud Green | Victorian terraces, post-war estates | Three councils have a claim on N4. Finsbury Park and Stroud Green addresses can sit in Haringey, in Islington or in Hackney, so establish which authority validates the regulations package before N4 drawings are submitted. |
| N8 | Crouch End / Hornsey | Edwardian terraces, Victorian villas | N8 covers Crouch End and Hornsey and sits wholly inside the borough. Haringey handles the regulations submission here, on stock that is overwhelmingly late Victorian. |
| N10 | Muswell Hill | Edwardian villas, 1930s semi-detached | Muswell Hill is cut by the N10 boundary. Haringey or Barnet may determine a regulations package there, so we check an N10 address against both authorities' mapping before anything is lodged. |
| N15 | Seven Sisters / South Tottenham | Victorian terraces, post-war estates | Seven Sisters and South Tottenham share N15, which lies entirely in the borough. The council takes the regulations package, and conversion work to flats is a large part of what it sees from these streets. |
| N17 | Tottenham | Victorian terraces, post-war estates | N17 is Tottenham, inside the borough throughout, so Haringey Council handles the regulations submission without any boundary question arising. |
| N22 | Wood Green / Alexandra Palace | Edwardian terraces, post-war flats | N22 is Wood Green and Alexandra Palace, entirely within Haringey. The council determines the regulations package, and the Alexandra Park designation is what most often affects work visible from outside. |
| N6 | Highgate | Georgian villas, Victorian and Edwardian semis | Highgate straddles N6. Camden and Haringey each determine work on their own side of the line, so an N6 address is tested against both before the package goes in. |
Haringey does not build to one pattern. Ridge heights, wall build-ups and back-garden depths shift from street to street, and each shift changes what a regulations package has to solve at that address.
Conservation areas covering Haringey: Haringey Council runs 29, and Crouch End, Tottenham Green, Bruce Castle are the ones Haringey owners meet most. A building regulations package inside a Haringey conservation area loses permitted development, so the Haringey submission is a householder application at £548 decided in 8 weeks — not a £249 prior approval decided in 6 weeks. In Muswell Hill a building regulations package is judged on the street elevation first.
What Article 4 removes near Haringey: Borough-wide Article 4 for HMO conversions. Before pricing a building regulations package we check whether the N4 address is inside the mapped area, because Haringey Council draws the Haringey boundary street by street rather than across the whole of Haringey.
Haringey housing stock: Edwardian terraces in Crouch End, Muswell Hill; Victorian two-up-two-downs in Harringay Ladder; 1930s semi-detached in Muswell Hill; post-war in Tottenham. Muswell Hill and Crouch End have strong conservation coverage with clear loft/mansard precedents; Tottenham generally permissive. Read that before choosing a building regulations package route in Haringey — construction, not postcode, sets what is achievable. Haringey Council charges £548 for a householder application and has 8 weeks to determine it.

Straight answers to the questions Haringey owners bring us about building regulations drawings.
Start a free quote →You have a choice in Haringey. Either the borough's in-house Building Control takes it, which is the LABC route, or a private approved inspector does. Neither route produces a weaker certificate; the law treats the two as identical. We submit wherever suits the project and the builder, which in practice often comes down to how quickly each can inspect.
What we charge for a Haringey regulations package follows the scope. The baseline is an extension or an uncomplicated loft. Above that sit HMOs, flat splits and basement conversions, all of which take considerably more detailing and more coordination between disciplines. Structural calculations are priced by the intervention, so a single beam across a knocked-through wall is a small item next to a whole loft, or next to underpinning. Current figures are on our fees page.
Yes. Any loft conversion in Haringey that creates habitable space requires Building Regulations approval, and that is true across England. Fire escape, the structure of the new floor, insulation and the staircase are all in scope. None of that has any bearing on planning permission, which runs on its own track: you can need one, the other, or both, and approval under one says nothing about the other.
Part L sets the minimum energy standard: insulation, glazing U-values, air permeability and the efficiency of the heating system. The 2021 amendments raised it substantially as a step towards the Future Homes Standard, and a new extension in Haringey is designed to what is in force at the date of submission. Every Complete package carries the Part L calculations and the compliance statement.
Haringey Council Building Control takes five to eight weeks to review a Full Plans submission. An approved inspector usually turns it around in two to four. Inspections then run through the build, typically six to ten visits depending on what is being done.
Building regulations approval is needed in Haringey for loft conversions, extensions, structural alterations, replacing a roof covering, forming any new opening in a wall, and effectively all work to a flat. A handful of things stay exempt, among them like-for-like replacement and a small porch. The free site visit is where we establish which of those two lists your job belongs on. Worth knowing before you assume the planning half is the harder one: of 287 larger householder extensions Haringey determined under the neighbour consultation scheme, 188 came back as prior approval not required, 32 were granted and 67 refused. A 23.3% refusal rate is a little below the 24.9% recorded across the 33 boroughs pooled, and note what the biggest number means — two thirds of those applicants were told to go ahead. Building regulations, by contrast, apply to all of them. Source: MHCLG live planning statistics
Compliance of the finished work is evidenced by one document, the completion certificate. It comes from Haringey Council Building Control, or from the approved inspector if you went that way. You will need it to sell or to remortgage, because conveyancers ask for it and lenders will not proceed without it. Booking the inspections in the right order and getting that certificate issued sits inside every Complete package.
An extension or loft conversion in Haringey that alters the building's energy performance needs the EPC updating, and the SAP or SBEM calculation behind Part L compliance is what supports it. We build those calculations into the Complete and Bespoke packages instead of invoicing them on their own.
