Description
Blackmore Mill House is a fantastic opportunity to purchase a gated, family estate, sitting on a spacious plot of around 3.421 acres (stls) and with accommodation which totals around 5075 of sq.ft. Consisting of a large, three-bedroom detached house, with en-suites to two of the bedrooms and three spacious reception rooms which include a fabulous kitchen/family room, in addition to three separate self-contained, detached annexes, a gym/summer house and a double garage, all set in well-tended grounds and being surrounded by open countryside to all aspects. Whilst the property is considered to be in rural location, viewers will note that it is just a short drive of around 4 miles into Brentwood Town Centre as well as being only 5 miles to Shenfield Town Centre where both offer a good selection of high street shops and well-regarded schooling . Both also benefit from Mainline Railway Stations which operate the recently opened Elizabeth Line in to London and Heathrow Airport. Viewers are urged to view at their earliest convenience to fully appreciate all that this wonderful property has to offer.
The main house has a large entrance hall with flagstone flooring which extends to all rooms on the ground floor. There is a large understairs storage cupboard and doors into all rooms. The living room benefits from having three sets of French doors, to two aspects taking in views of the gardens and having direct access onto the patio areas. There is a further siting room, again with French doors to the garden. The heart of the main house is most definitely the kitchen / family room which has a lovely bespoke kitchen, fitted with wooden wall and base units with polished granite worksurfaces and there is also a central island unit. Integrated appliances include double ovens, gas hob with extractor above and there is ample space for freestanding appliances. Rising to the first floor there are three double bedrooms, all with built-in storage. Bedrooms one and two have en-suite shower rooms, and bedroom one further benefits from a lovely balcony with views over the gardens. There is also a separate family bathroom on this level. It is also worth noting that planning permission has been passed to extend the main residence adding a reception room to the ground floor and further bedroom with en suite to the first floor.
As previously mentioned, included in this sale are three, self-contained, detached annexes. Each annex is of a good size, and each has as a minimum, bedroom space, living area and shower room, both en-suite and separate. Two have separate laundry rooms and there is a separate fully fitted kitchen in one of the others. The largest annexe features a fantastic family room of almost 60’ in length where you will find a fabulous bar area with extensive seating, there is also space for a pool table, whilst to one end of the room there is a media wall with ample space for seating. This annex also features a separate sauna and separate w.c with wash hand basin. A spacious gym/summer house of some 25’ in length has two sets of French doors to the exterior and features a fully fitted kitchen area, plus a free-standing bath.
As previously mentioned, this fabulous family estate sits in grounds of around 3.421 acres (stls) which includes extensive parking to the front, including a double garage all set behind double wooden gates.
