Adding an internal window can be a great way to ensure natural light reaches dark areas of a home.
Our original plan to lighten our dark hallway was to add a skylight when we removed the lift. We’d originally planned to lighten our dark hallway by adding a skylight when we remove the lift. But that does not work with our chosen layout. The next option is to put an internal window between the hall and the south facing dining room next door. The question is how to do it so it looks intentional and not out of place.
Internal window ideas
Thanks to significant internet browsing, I now know there are many choices. Although these will vary depending on the rooms either side of the window (look at my Pinterest board for inspiration). The most relevant for us are:
- plain window – these can vary in size and shape to fit around the staircase
- patterned window – either stained glass or a frosted pattern
- row of shallow windows
- tall windows
Internal windows for our house
As well as wanting to add an internal window, or two, we want to rotate the staircase. The half turn landing will be on the wall between the hall and dining room (the wall on the left in the photo below). This is an added complication as it is hard to picture what it will look like when we don’t have the actual wall yet.

Our first idea was to put a window across the width of the half turn landing. However we decided it would look like an after thought rather than a planned addition.
Our second thought was to add detailing to the window such as stained glass and match it with detailing in the front door when it is replaced. However this wouldn’t change the fact that the window would be floor to hip height on the stairs and a high window in the dining room.
Our next thought was a row of windows. But decided no as they would probably be too high for the children comfortably to look through.
This left narrow windows. They would be great for the children to look though, but may not give enough light into the hall. So we added two taller windows on either side of the staircase, and hoped this would also make the windows look more ‘normal’ from the dining room.

Window size
We like how these windows look from both the hallway and dining room. But aren’t sure about the length of the tall windows. My initial thought was to have shorter windows so we could put furniture underneath them e.g. a sideboard in the dining room.
But as the point of having an internal window is to increase the light flow full length windows make more sense. I’m not sure they are practical, but there is certainly something special about them. What do you think?

Potential issues
Seeing our finished hall in 3D* has really helped us understand how it will look when we fit the internal windows. However it has also raised some questions. For example the staircase in the current plan overlaps the lounge doorway:
- Will this make it difficult to access the lounge?
- Does this mean the first step of the staircase should be further back by adding steps on the turn?
- How will impact on our window plan as the half landing floor height may not be level?
We don’t know when we’ll start the work as the lift removal needs careful planning, but the prospect is very exciting. In the meantime I’m looking forward to modelling our kitchen / dining room and see if we can resolve the issue of whether the kitchen should be at the front or back of the house.
*Disclaimer: I’ve created the 3D images in RoomSketcher and was given a free VIP account to try. They also offer a free access level which will enable you to create floor plans, see them in 3D and take 3D snapshots (but you won’t be able to take premium photos as I’ve used here).
Edit: Since publishing this post I’ve been told RoomSketcher can produce 360° views of of floor plans, so here is our hallway (note the central point is not the same as the video because there would be a a very boring section of just wall).

Crikey it’s so much work. Loving the 3d images though – technology does help envisage what things look like.
I love the full length windows, but they will make that space inflexible. In our house we’ve got windows both end of our kitchen, and on 3 sides of our living room – means serious lack of space for storage.
Must be very exciting planning it all! I’d echo Emma’s comment re strorage/furniture along that wall, but having the two half height windows may be enough to solve that. Secondly, you will need to be careful of that overlap of the stairs with the door and the distance that you offset the stairs, although it may just be a visual issue. It also might be worth adding your banister into the visualisations, it may look quite different with it in place. (sorry, the building engineer in me just took over…!). Back to my starting point, very exciting!
I think that the full length windows would work really well. I especially like the decorative window in the first selection, too.
Wow – what a lot to think about! Roomsketcher looks like a really helpful tool!
Good luck making your decisions – they seem very ambitious to me.
Ooh, I love planning house alterations! I think your hall will be totally transformed and will really open up your entire house. As regards windows, personally I think the 3/4 length windows look better as I feel they give a more balanced look, the full length ones make the area look smaller to me. Also in practice full length windows will end up being covered with fingerprints!
Good luck making your decisions, I love the 3D drawings, so much easier to picture the final product.
Did yo decide on the internal window. We are currently building a new house and have a similar idea but was thinking of having a frosted window and some method of lighting it in the evenings. Have you come across any such designs.
