Pitstone lofts and rear extensions with skylights and rooflights
Pitstone runs from a built-up western edge to quiet, rising farmland. Below, each kind of roof on the way there is matched with the glazing that fits it.
A village of two characters
Pitstone, an east Buckinghamshire village and civil parish, sits at the foot of the Chiltern Hills. The parish is long and narrow. The western end, towards the Grand Union Canal, is built up in a semi-urban way; the rest is rural and climbs gently as you head away from it. A rooflight that makes sense on one side of the village can be the wrong tool on the other, so it helps to think of Pitstone as two settings for the same sky.

Homes out on the rising ground
The village shares its doctors and dentists with nearby Tring, and at this end housing and business units such as the Castlemead area, named after the last owner of the cement works, sit close together. Plots are tight. A back extension or a converted garage can have a window that looks straight at a boundary fence, and the room behind it never quite fills with daylight. Whether it is a flat rooflight over the extension or a roof window set into a loft slope, the light arrives from overhead, the one direction a neighbour cannot block.
Beyond the built-up edge the parish turns to open country, and the village's farming past is still on show at Pitstone Green Museum. Houses out here sit on larger plots, and the older ones can have roofs that have been patched and re-covered over the years. Rooms under the slope can be tall but dark. A roof lantern on a newer rear extension, or a slim roof window set between existing rafters in an older loft, brings in sky without changing the look of the front of the house.
Light for Pitstone lofts and rear extensions
The extension looks at a fence
Boundaries are close on the built-up streets, and a side window only sees them.
Sideways
A rear extension on a tight Pitstone plot is a good way to gain space, but the wall that faces the garden boundary can be only a few metres from a timber fence. Glass in that wall gives a view of panelling. The light that arrives is low, grey and gone early in the afternoon.
The room ends up lit by lamps at lunchtime. The dining table sits in the dimmest part of it, and the family walks to the other end of the house to find a bright seat.
Adding a bigger window to the side wall does not fix this. A larger opening still faces the fence, and it adds a view into the neighbour's garden that neither household wants.
Straight up
Set into a flat roof, a rooflight opens the centre of the room to the sky, beyond the fence's reach. Its glass is set on an insulated upstand and angled to shed rain, and neat plasterwork round the opening inside makes the ceiling look designed rather than cut.
If the extension is wide, a pair of rooflights in a line spreads light along the table. If it is square, a single larger pane over the centre does the same job. A lantern is the other choice when the ceiling has height to spare.
Straight up is clear. That is the whole reason the roof is the right place to put the glass when the walls are hemmed in.
Before any glass is ordered, we look at the existing roof structure, the fall of the roof and what the build-up is made of. Our survey costs nothing, and the quote that comes after it is fixed in writing, so the number you agree is the number you pay. Where the work needs Building Control notification, we handle it.
Planning for an extension roof is a separate question from the rooflight itself, and the rules depend on the house. Our planning guide explains how to work out where you stand, and the Buckinghamshire Council planning team can confirm anything particular to your street.
One thing to decide early is what the room is for. A kitchen extension wants light over the worktop and the table, so the glass moves towards the middle. A family room wants even brightness across the sofas, so a pair of smaller panes can work better than one large one. A home office wants light that does not throw glare onto a screen, which points to glass above and behind where the desk will sit rather than directly over it. We talk these choices through on the day, with the tape measure out, because a drawing can hide how a room really gets used.
Questions to settle at the survey
- How far is the nearest fence or wall?
- Where does the table or worktop sit?
- Is the roof flat or pitched?
- Will the ceiling be re-finished inside?
- Is fresh air from above part of what you need?
A loft in the shade of a tree
A good tree is worth keeping; the daylight can come from higher up.
Sideways
On the rural side of Pitstone, gardens can run to old hedges and tall trees. They are lovely from a distance, but from a dormer or gable window they fill the view and drink the light, especially in summer when the leaves are full.
A loft bedroom behind that kind of window can feel like a green cave. Bare branches in winter let more light through, yet the sun sits low and the room runs cold. The window gives a view, yet little brightness, and the room never feels finished.
Straight up
A roof window is set into the slope above the tree line of the view you actually look at. The line from the room to the sky rises past the branches, and daylight pours over the floor instead of stopping at the glass. Placing the window towards the upper part of the slope improves the angle further.
Roof windows come in opening and fixed forms, and a pair side by side suits a wider room. Both fit between the existing rafters, so the main frame of the roof stays as it is. Sizes are described by a VELUX code, where the letter is the width and the digits are the height, and we work through the right one during the survey.
A loft conversion has its own rules for stairs and escape routes, and those are set by Building Regulations rather than by the window. Installation follows the Building Regulations as they stand, and any notification the work needs is made by us. The Buckinghamshire Council building control team has its own guidance, and we are happy to talk it through with you.
The village sits close to the edge of the Chilterns, though outside the AONB, so a planning check against the council's own information is a sensible first step. If a particular tree is protected, that is a matter for the council, not for the rooflight, and it does not change where the glass should go.
Sun is the other thing to weigh in a loft. A slope that faces the afternoon sun brings warmth as well as light, and a bedroom under it can feel bright at the wrong hour. The glass can be specified to cut some of that heat, and blinds fitted to the frame handle the rest. A slope facing away from the sun gives gentler light all day, which suits a study or a playroom. The tree that shaded the old window may even help in summer, filtering the strongest sun while the new glass still lights the room.
| Setting | Light | Why it suits |
|---|---|---|
| Tight extension, close fence | Flat rooflight | Sky over the middle of the room |
| Taller extension ceiling | Roof lantern | Light from several sides above |
| Loft under a mature tree | Roof window | Clears the branches in the slope |
| Dark landing or hallway | Sun tunnel | Small opening, bright shaft |
Planning in Pitstone and the Chilterns edge
Pitstone falls outside the Chilterns AONB, but its boundary is only about one kilometre away, and Buckinghamshire Council is the authority that decides applications here. Buckinghamshire Council's planners can say whether any local designation applies to your street, including a conservation area or an Article 4 direction, and we would always suggest asking before work is ordered. Conservation status alone leaves the right to alter a roof untouched, whereas an Article 4 direction can withdraw it.
Rather than set out the permitted development rules here, we keep them in one place. Our planning guide explains them, and the council's own planning pages are the authority on the local detail. The building control pages explain how the Building Regulations side works, and a private registered building control approver is the other route.
Listed houses are a different matter again. Any change to the roof of a listed building needs listed building consent, whatever the rooflight is.
If you plan to have the work done as part of a bigger project, such as a new extension or a loft conversion, tell the council's team about the whole scheme and not just the rooflight. The rooflight is the smallest part of the paperwork and the easiest part to fit into a plan that is already approved.
How we reach Pitstone
A 19.9-mile drive from Milton Keynes, roughly 27 minutes, brings us to Pitstone, which lies south of us. That is a comfortable journey for a survey visit. With Cheddington, Tring and Eaton Bray all nearby, one day in the area can cover more than one household, and nobody waits long.
Pitstone has a long memory. The name is Anglo-Saxon, said to mean Picel's thorn tree, and the village was already written down in the Domesday Book of 1086. In 1283 the Earl of Cornwall gave it to the abbey at Ashridge, and the cement works that ran from 1937 to 1991 shaped its twentieth century. A place with that many layers has houses from different periods, and each one is covered and lit in its own way. That is why we look at the roof before we talk about glass.
Inside a Pitstone home: what the survey looks at
The survey starts with the room you want to brighten and works up from there. We note the roof type and covering, the rafter spacing in a pitched roof, the depth of the build-up in a flat one, and what sits on the other side of the ceiling. We look at which way the roof faces and where the sun tracks across it, because that decides how warm and bright the room will feel at different times of day.
Then we go through the choices with you. A flat rooflight suits a low-pitched or flat extension roof. A roof lantern suits a ceiling with some height. For a loft slope, a roof window is the right product. Where the roof is far above a landing or hallway, a sun tunnel carries daylight down to it. We only recommend what suits the roof in front of us.
When a room has a hard problem, a hallway with no window at all being one, we say so plainly and set out the realistic options. A good survey leaves you knowing why one choice beats another, even if you choose to go ahead with someone else.
You then get a fixed written quote that does not change on the day, and a 10-year workmanship guarantee in writing. A typical rooflight is fitted inside two days, and the room is finished and left clean afterwards.

Pitstone homeowners ask
Is Pitstone inside the Chilterns AONB?
No. Pitstone is outside the boundary, about one kilometre from it. For any other designation on your street, ask Buckinghamshire Council; our planning guide shows how to go about checking.
Can a rooflight go in an older house in the village?
Older roofs are built differently, so the survey looks at the covering and the timbers before anything is recommended. On an older house a slim roof window, or a small flat rooflight, is the usual fit; a listed building needs listed building consent before any of it. Your address is one for the council's planning team to confirm.
How long does the drive from Milton Keynes take?
Take the road south from Milton Keynes: 19.9 miles, about 27 minutes. To fix a time, ask for a free quote; the visit sits comfortably inside a morning or an afternoon.
