How we work on velux loft conversion drawings
Nine steps from first call to approval.
Enquiry and constraints check
We check the property against conservation areas, listed status, Article 4 directions, tree preservation orders, flood zone and planning history. We choose the right route and send a fixed quote.
Measured survey
We survey the house on one datum: rooms, levels, boundaries, drains, trees and the neighbours' windows that the 45° and 25° tests depend on.
Design options
We model the house in Revit and show you options in 3D and plan, with the planning strategy and the precedents in your street.
Design frozen
You choose an option in writing. Nothing changes after this without your say.
Independent check
A second chartered technologist checks every sheet against the council's validation checklist and the policy. A senior review signs it off before anything is submitted.
Submission
We prepare the forms, certificates, fee and documents and submit through the Planning Portal.
Officer liaison
We answer the planning officer and make any amendments within five working days, at no charge until approval.
Building regulations
Technical drawings are coordinated with the structural engineer's calculations, the drainage and the planning conditions.
Approval and hand-over
Building control approval, then a next-steps pack covering the commencement notice, party wall timing and CIL.
Free redraws until approval. Every drawing set is checked independently, and the checker is never the person who drew it.

Reading Haringey's directions and heritage
Haringey has 25 Article 4 directions and 33 conservation areas, and Historic England lists 289 entries in the borough. A direction or a listing can turn a rooflight that would be permitted development elsewhere into a planning application, and a conservation area brings closer scrutiny.
We treat the heritage check as the first step, not an afterthought. The result tells you whether to expect a certificate or a householder application, and it tells us how conservative the roof drawing needs to be.
Haringey also has a specific local document, the House extensions in South Tottenham SPD (revised). It is aimed at one part of the borough, and we read it for any house that falls near it, because it shows how the council likes roofs and extensions handled in that area.
Where a direction applies, the application is for the roof alteration alone, and the officer looks at it as a roof element: size, position and the effect on the terrace. We keep the written explanation short and lead with the drawing.

Loft enlargement in section: the permitted development limits
A dormer on the rear slope, with the limits that decide whether it needs planning permission.
- A · Extra roof volume allowed
- 40 m³ (terrace house) / 50 m³ (any other house) additional roof volume
- B · Set-back from the eaves
- Original eaves maintained; enlargement set at least 0.2 m from the eaves measured up the roof slope, so far as practicable (not required for hip-to-gable or roofs joining a rear/side extension)
- C · Height limit
- No part higher than the highest part of the existing roof
How Haringey householder decisions look
The council decided 689 householder applications in its latest published year and granted 90.3 per cent, with 94.3 per cent decided in time. That is a healthy record on both counts.
It is a borough-wide record across every householder project, so we use it as a guide to timescale and not as a prediction for any single roof.
Haringey is also a borough where many houses have already been altered. A loft that was converted by a previous owner may have no consent or certificate on file, and buyers often find that out at the conveyancing stage. If that is your situation we can draw what is there and what you intend, so a certificate or retrospective route can follow.
Velux loft conversion drawings in Haringey: the Tottenham and Crouch End terrace
Only 38.9 per cent of households here live in a house or bungalow, and a terraced house averages 803,381 pounds. The terrace is the type we draw most often: a narrow roof, a central ridge and a back addition that interrupts the slope.
That back addition matters. It splits the rear roof into two planes, and the rooflights have to avoid the valley between them. We survey the valley and the party walls, then position each unit so it clears both. Where full stair headroom cannot be achieved the Approved Document accepts: Loft conversions where 2.0 m cannot be achieved: 1.9 m at the centre of the stair, 1.8 m at the side (half width).
Choosing between a certificate and an application
If your roof keeps its rights, the rooflight must meet this limit: Roof alterations (e.g. rooflights) may not protrude more than 0.15 m beyond the roof plane. A Lawful Development Certificate then records the position. If it does not, we submit the same sheets through planning drawings in Haringey.
The building regulations side is separate and always applies. For escape, the guidance says: Escape window: unobstructed openable area at least 0.33 m², at least 450 mm high and 450 mm wide, bottom of opening no more than 1100 mm above floor. Our building regulations drawings in Haringey cover the detail.
The stair is the place to spend design time. On a narrow terrace it usually rises over the existing flight, which means taking floor from the room below, so we try two or three positions on the model and show the effect on the first floor before you choose.
Cost and related pages
Our fee is fixed at £695 including VAT. Every sheet is checked by a second MCIAT chartered technologist, and we redraw without charge if the council asks for changes.
If the slope will not give enough height, compare dormer loft conversion drawings in Haringey or the overview at loft conversion drawings in Haringey. The borough guide is architectural drawings in Haringey; the national page is Velux loft conversion drawings.
The price covers existing and proposed plans, elevations, a roof section and location and block plans, with any measured survey agreed in the quote up front.
