Hi any window specialist.

I’m having a 2 floor extension on a 1930’s house with original
wooden casements fitted. I’m looking for a wood effect satin finish flush fit white casement, but not sure which company to use? I have seen sash windows on Kings House, a new development on Brighton seafront that look virtually identical to painted sashes, not sure which company fitted them. Any ideas which company
make good quality casements
at a reasonable price?, my preference is for a window that looks from a distance like the original wood painted ones. Mine have lead cross section to front upper openers. I’m
planning on just replacing in the extension until funds permit me to do the whole house. I’m
looking for any independent recommendations on suitable

Can't recommend fitting companies but Residence 9 make the system your after, pretty sure their website will put you in touch with approved installers, it's the dogs but beware it's not cheap

Can't vouch for them but it was probably Pembroke and Nash who fitted them.
And they're Residence 9 windows.
Most window profiles do a ' Flush ' Sash window now ( Rehau, Profile 22 , Decuekinnick , Veka etc ), Residence 9 were the first to bring them to the market , and probably still lead the way. I think you will struggle to replicate the ' arch ' in each sash though.
I got flush sash in my house.

Looked at Residence 9 but got elsewhere, as R9 have a cost premium.

Flush sash is nice, no welded mitres, looks like the original wooden ones they replaced (in form anyway). Still obviously UPVC as I didn't fancy the fake wood foil but really happy with them.
I think these guys may be able to do the arched bits, they can do welded or mitred joints.

looks like they do arch frames , but the arch on OP's windows is considered a ' stick on ' to the glass , tried to get these recently and couldn't find anywhere they does them , seem to be a casualty of the Pandemic. We seem to find that very rarely asked for ' additions' and glass is disappearing form the marketplace
Do not mind no arch top, still look good square, seen a few Residence9 bad reviews online though, jamming up & coming apart, not sure how true that is & I understand their Ali not upvc.
Not seen in a showroom , but
Deceuninck look good with 1930’s
style handles & stays too. I like the idea of satin white finish, not glossy shiny white, do I need a ‘wood effect foil’ for that & can the foil come loose?, also my 1930’s
windows are structural supporting
So the new windows will need to have strong frames, I’ve heard of Rehau but not Veka or Profile22
which would be best out of the 4?
The foil won’t come off. I’ve got Anthracite foil on the outside.

I’ve got Deceuninck and I think it’s a well made system and not mega expensive.

Residence looks a little better, but was much more expensive. Can’t comment on the other profiles.

Mine are Graf welded, which looks like a mitred joint not a weld.
Had a look at the ‘bisonframes’ website, their genesis flush sash
look quite good, very similar to the Decueninck windows with
Graf welded or mechanical joints,
not sure if pricing is similar.
They are Decueninck frames from Bison.

Three sash, all openers, flush casement 1600x1200mm was around £500 foiled on outside.
We fit Decueninck ( though I can never spell it correctly lol) , never had any issue with the actual Flush Sash Frames at all, external glazing bars a different matter but thats down to my supplier not the profile. R9 are more complicated to fit ( dummy sashes in particular !) and imho opinion , overpriced. Rehau , Profile 22 ( now known as Optima ) , decuekinck, Veka all use very similiar systems
