Velux loft conversion drawings in Bromley

Why Bromley needs a careful address check

The borough has 108 Article 4 directions and 47 conservation areas, and its 412 listed entries add to that. A direction may withdraw rights on part of a house, so the front slope can need an application while the rear does not. We read the direction for each road, not just the map.

The borough is also partly rural. Green Belt covers 51 per cent of the borough, and although a rooflight is not a new building, a house in the Green Belt can have its own history of extensions that has to be added up before more work is done.

Whatever the planning route, one building regulations rule shapes the stair and the doors: New storey above 4.5 m by loft conversion: protect the full escape route with fire-resisting doors (min E 20) and partitions (min REI 30). It applies in every borough.

Appeals and the householder record

Bromley decided 1,609 householder applications in its latest year. It granted 78.6 per cent and decided 89.1 per cent in time.

Refusals are tested here. The Planning Inspectorate decided 502 householder appeals in the borough and allowed 37.6 per cent. That does not tell you how your own rooflights will fare, but it shows that applicants do challenge decisions, and that a clear record of the roof, the neighbours and the design helps a case on appeal as much as at the first stage.

For a Velux scheme that means sending the application with a roof section, photographs of each slope and a plain statement of the rooflight sizes. There is then little for an officer to resolve.

Houses, prices and why the loft gets used

Bromley is a borough of houses: 68.6 per cent of households live in one, and the average terraced house sold for £483,699 in the latest figures. The share of owner-occupiers is 68.5 per cent. Owners with a settled home and a spare roof void are the ones who ask for lofts.

We do not make claims about what a conversion adds in value, because the sales data does not show it. What we can show is the room: a measured section, a stair that works and a bed that clears the slope.

Designing the roof room around the rooflights

On a Bromley roof we place the stair first and the units second. The stair needs its head clear of the slope, so it lands under the ridge; the rooflights then go where the floor will be used, one over the stair and one or two over the sleeping area. If the slope is shallow, a larger unit can replace two small ones, which keeps the roof calmer from the street.

We also show how the new floor is carried. Most loft floors begin as ceiling joists sized for a plaster ceiling, and they rarely suit a bed and wardrobe without help. The structural note on the section tells the builder where to add timber or steel, and a structural engineer can supply the calculations when the spans are long.

Finally, the roof void often holds a water tank, flues and wiring that must be moved. We list them on the existing plan, so the quote you receive from a builder includes them.

Certificate or application, and what comes in the set

Where rights hold, a lawful development certificate confirms the work without a planning application. Bromley dealt with 512 certificate applications of all kinds in its latest return. If the address fails the check, a householder application follows instead.

The set holds existing and proposed plans, a roof section dimensioned for stair headroom, elevations of each slope and the location and block plans. Velux loft conversion drawings start at £695 including VAT, fixed before you commit. A second chartered technologist checks every sheet and we redraw at no charge if the council asks for changes.
