Modify stairs

[Bahco]

Hi fellas
I have a standard straight 13 tread staircase that I would like to modify and move to another room creating another opening in the ceiling.

I would like to have an open plan staircase in the living room with a quarter turn.

Can anyone advise me on the best way and can these stairs be modified etc or do I need to purchase a new one.

I am in Wolverhampton so if anyone can sign post me to a good supplier or a link I would be grateful.

Much obliged B

You will have to have a new one manufactured.... cannot point you in the direction of a manufacturer

Have bought some Burbidge parts off them and intend fitting their glass panels - very helpful.

Showroom only open weekdays.

My opinion FWIW, if the overall height and run of these stairs will be the same as required in the new position, and assuming that they can be removed without damage, there's no reason, that I can see, why they should not be re-used.
Asssuming also that they conform to regulations.

Can they be cut / modified and a quarter turn added?

Not a joiner but the string of a straight run is the wrong shape to handle a corner.

Do you want a quarter turn landing (may be wrong term) or winders?

 

[RedHerring2]

If it's a quarter turn you want and you intend to construct a self-supporting stable landing, then there's a real possibility of modifying the stairs to meet the new landing.

If you construct the landing about 50mm wider (from the quarter turn flight) or longer ( from the main run flight), then the stringers may be modifyable. By notching out a 50mm wide piece from the bottom of the stringers where it will sit on the new landing, and ensuring the new landing is not going to move anywhere, the stairs should be perfectly stable.

Alternatively a 75mm X 50mm piece of timber across the back of the new landing to support the bottom of the stairs.

The benefit of the notch in the stringers is the support from underneath and the prevention of any travel.

If you have a look in the My Projects forum and my post about Renovating a House in France, http://www.diynot.com/forums/viewtopic.php?t=237971 you'll see the stairs that I constructed last year.
I made the landing from 100mm X 50mm, covered with 18mm ply.
I put 2 additional joists underneath the landing, after constructing the landing framework.

and you cannot do it....
look at the original reply.

Some explanation to support your argument would help me and, possibly, the OP.
A simple "No, it can't be done." is just not enough.

All he's doing is shortening the overall height and the run of the stairs by constructing a new landing for the quarter turn.

well if no is not enough... just do it..... then you will find NO

and he is not shortening the height... the rise is the same... and trying to extend the going... impossible...

 

[RedHerring2]

As I see it, he is shortening the overall height of the stairs, by creating a landing for the quarter turn. This landing will take the place of one of the treads, therefore the going (of that flight) will remain the same.

How can he insert a landing without reducing the overall height or reducing the going of that flight? And certainly not extending the going.

I think one of us have misinterpreted the OP.

I think he can re-use this flight in another area, if the height and going is the same, or he can modify the stairs to include a quarter turn landing.

What I don't think he could do is to modify the stairs to allow an open riser style, because the treads would need some "beefing up".
Also depending on his stringers, he might have the empty "housing" on show.

Having thought about this I would go with RedHerring2

If you look at this

http://www.stairplan.com/staircases.htm

Which I guess is something like what the OP is looking to achieve

It could be done by shortening an existing run to form the upper part and building the landing and lower run from scratch. There may be a short newel at the far side where the string meets the landing but can't see in the picture.

 

[RedHerring2]

Precisely IJWS15.
A couple of points on the stairs in that picture:
1. It looks as though they have done what I talked about, notching out a lower bit at the bottom of the upper stringers to sit on the landing. they've also done the same with the first short flight, ie. notched out a bit at the top of the short stringers.
2. The landing sub-structure looks a little feeble, IMO.

all depends if the outer edge off the treads carry on being the exact same on the winders
if its any longer then you have the groove for the riser and part off the groove for the next tread showing

have you thought about a newel post and connecting the stringers to the landing....
