MARK Wright has revealed the stunning staircase transformation at the mansion he shares with wife Michelle Keegan ahead of the arrival of their first child.

Coronation Street alum Michelle, 37, revealed she is expecting her first baby with TOWIE favourite Mark, 38, in December.

The Sun has since revealed the TV favourite is "weeks" from giving birth.

Michelle previously captured herself hunkering down at the pair's stunning £3.5million Essex home during her pregnancy as freezing cold temperatures hit.

Now the couple's home Instagram account details the "mind blowing" transformation of their spiral staircase, which now sits pride of place in the middle of their home.

Images show the spiralling white marble steps adorned with elegant black railings leading to the upstairs floors.

A chandelier with white glass baubles hanging down from the high ceilings adds extra glam and draws the eyes down the centre of the staircase back down to floor level.

In their latest upload, the couple also shared never-before-seen snaps of how the staircase looked prior to the work.

In the caption, they wrote: "Still mind blowing how the staircase ended up. Swipe for before’s. Designed & built by @escalier_uk."

Their followers were quick to respond, with one writing: "What a beautiful staircase. What’s that lovely flooring I see on the landings."

Another put: "This is how I want my stairs but I just remembered I’m not rich," as a third commented: "Sooo beautiful."

A fan then posed: "Like a 5 star hotel, money well spent!!"

One then advised: "Lovely x but please make sure your baby will be safe when they start walking."

Last month, Michelle opened up on her "self care January" which included snaps at her Essex pad.

Previously, she gave a glimpse into the pair's cinema room.
