Hello, I was hoping someone may be able to assist

Hello, I was hoping someone may be able to assist with sourcing a company who specialise in doors and windows in Solento, Puglia. We have been slowly improving the holiday property and now is the time to change shutter doors. Our issue is the main stream DIY chains, such as Tecnomat, do not hold the specific size required 250H x 105W (ours is slightly different - by my measurements) than what appears to be the standard 220H x 120W.

If anyone has any advice or has used anyone in this region, I would appreciate any tips, headers please?

Thank you

Marco
