This Grasmere estate wouldn’t look out of place in the Hollywood Hills, but wait until you see inside.

A sprawling Hollywood-esque southwestern Sydney estate with 1200 sqm of combined living space has been listed for sale.

The six-bedroom Grasmere property, built by an owner-builder, sits on 2.54 hectares of level ground and even has a two-storey granny flat that sits above the four car garage complete with steam room and Sonos audio system.

The Grasmere property has amazing views.

The covered alfresco area with direct access to the kitchen.

The granny flat has a Smeg pyrolytic oven and convection microwave, stone bench tops and polished concrete floorboards inlaid with glow-in-the-dark stones. There are also sheer and 85 per cent block out curtains.

The main house features a sunken lounge in the middle of the home with an incredible custom-made chandelier.

The lounge area has a Gyro focus suspended fireplace imported from France, lighting salvaged from a shipwreck and programmable curtains and automated louvred windows.

The lounge is custom designed and the floor is made from recycled Oak.

Exposed airconditioning ductwork and steel beams give the living and sitting rooms an industrial feel.

The stylish and functional kitchen.

The kitchen is an exercise in on-trend design. It is built with a huge Calacatta marble and brass bench, handmade concrete sinks and handmade brass tapware.

There is also an internal barbecue area with industrial range hood and indoor woodfire pizza oven with commercial extraction exhaust and gas burner.

The kitche has a built-in woodfire pizza oven.

The subzero fridge, worth an estimated $50,000, was custom made in the US and is housed in Calacatta marble.

The kitchen has three sinks in total, one sink in oversized stainless steel, two custom cooking towers (one next to the internal barbecue) and two semi-commercial Smeg dishwashers.

A butler’s pantry is hidden behind three Fenix automated roller doors complete with two Smeg pyrolytic ovens and one convection microwave and steam oven.

A standout and timeless colour scheme.

Everything from the curtains to the lighting in the home theatre can be controlled by an app.

The property also features a self-contained two-bedroom guest residence, home theatre, gourmet kitchen, master suite with dressing room, billiard room, pool, spa, steam room, fireplace, dining terraces and playroom.

The main home has a fully wired Sonos speaker system and C-Bus lighting system throughout with all security cameras operable through iPads and smartphones.

The heated pool has an automated chemical system as well as internal lighting, large sitting area with feature bubble system and feature moat. All spa jets, lighting and bubble systems are controlled through the dedicated C-Bus operating system.

Uninterrupted views from the master bedroom.

Another bedroom overlooks a wing of the estate.

To keep the lawns looking their best the home features an automatic lawn and garden irrigation system, and 120,000 litre rainwater tank stored under the feature pergola.

The home has a Fronius solar panel system providing a total of 8kw of solar panels with 6kw of battery storage.

The property is large enough to further subdivide into three additional lots sized over one acre, subject to DA approval.

Agent Stuart Davies from Davies Inglis Properties said the expressions of interest campaign will continue to November 20, if the home is not sold prior.
