Rooflights and skylights in Hampton

That is not the end of the planning question, though. A house built under a fresh planning permission can carry its own conditions, and some new-build estates have conditions attached that remove or limit permitted development rights on particular plots, quite separately from any conservation designation. Nationally, permitted development for a roof alteration also depends on the alteration not projecting more than 150 millimetres beyond the plane of the existing roof slope, among other conditions, and on nothing having already been added that uses up the allowance. None of that is guesswork on our side. We check the planning history for the address, alongside the roof itself, before a rooflight or skylight goes on a quote.

Building Regulations sit alongside planning permission, not instead of it, and they apply to every rooflight job regardless of conservation status. We install to current Building Regulations and handle the Building Control notification where the work is notifiable, so that part of a Hampton job runs the same way it would anywhere else we cover.

A flat rooflight set on an upstand gives an unbroken pane of glass with no central bar, which suits that lower, seated eyeline well, and the falls built into the upstand keep water moving off the glass rather than sitting on it. Where the ceiling below is deep, because of insulation added to meet current regulations, the reveal needs planning too, since a thick, square-sided lining can turn a generous rooflight into a narrow patch of sky by the time you are looking at it from the table. Our flat roof rooflight installation page covers upstands, falls and glazing options for exactly this kind of extension in more depth.

Where a family wants more than one pane, a lantern raised over a wider kitchen-diner gives sky from several angles rather than one central rectangle, and the hips and glazing bars of a lantern can be arranged to keep the view open from the seats people actually use, rather than from the middle of the room. That is covered on our roof lantern installation page.

Hampton stands on ground the brick industry left behind, and that history now shapes the outlook from many rear-facing rooms that back onto it. The old clay pits between Hampton and Orton have filled and settled into Hampton Nature Reserve, also called Orton Pit, a roughly 300-acre site of undulating ground and around 320 ponds, now a Special Area of Conservation and a Site of Special Scientific Interest, with Haddon Lake sitting alongside it. Around 110,000 trees have been planted through the wider development, and at least half of Hampton's total area is kept as open space, threaded by Peterborough's 50-mile Green Wheel cycling route.

For a rooflight, that open, low-lying land to the south and east means a rear roof slope over the reserve or one of the lakes can frame sky with very little to interrupt it, in the same way the Fens do further out from the city. Placed and lined correctly, a rooflight in a rear extension backing onto that open ground can give a genuinely wide, clean view rather than a narrow slot between neighbouring rooflines. Our frame profiles and sightlines guide explains how the width of the frame and any glazing bar changes how much of that open sky you actually see.

Water nearby also means humidity nearby, and a rooflight close to open ponds and lake edges is tested by damp air as much as by rain. A warm edge spacer and a properly sealed unit keep the pane clear rather than misted between the panes, and where an existing skylight has already gone cloudy, our guide to keeping rooflight glass clear sets out what actually prevents that, alongside the specification choices on our misted and failed rooflight replacement page.

Is Hampton in a conservation area?

No. Peterborough City Council's published list of conservation areas does not include Hampton, so the extra planning controls that apply in an older part of the city, such as an Article 4 direction, do not apply here. Individual plots can still carry their own planning conditions, which we check for the address.

My loft has a trussed roof. Can I still get a rooflight or a proper room up there?

Often, yes, but it depends on the truss type. Some Hampton houses were built with an attic truss already designed to take a room, in which case a roof window can go in much like a rafter roof. A standard truss usually needs an engineer's design for the new opening before any glass is chosen.

We have a flat-roofed kitchen extension. What are our options?

A single flat rooflight on an upstand gives one clear pane with no central bar, which suits a table or a sink view well. For a wider kitchen-diner, a lantern raised over the flat roof brings in sky from more than one direction. Both are planned from the seat you actually use, not the middle of the room.

Do you cover the areas around Hampton as well?

Yes. Nearby, we have pages for Orton and Werrington, two of Peterborough's other new-town neighbourhoods, each with its own roof types and planning notes.
