Description

Occupying a stunning south facing plot of approximately 7.5 acres in one of the area's most sought-after private woodland settings, The Old Tower is a truly exceptional detached residence combining distinctive architecture, extensive leisure facilities and beautifully established grounds.

Originally commissioned by an architect as his own home, the property is centred around a striking circular tower which gives the house its unique identity and enduring appeal. Over the years the house has been carefully enhanced and extended to create a substantial family home that effortlessly combines architectural character with modern comfort and outstanding leisure facilities.

The welcoming reception hall sets the tone for the property, leading to a magnificent drawing room with multi-fuel stove and views across the gardens, a handsome study, dining room and a characterful sitting room with exposed timbers and an impressive inglenook fireplace. At the heart of the home is a luxury Martin Moore bespoke kitchen and breakfast room featuring handcrafted cabinetry, an Aga and generous entertaining space, complemented by a bar and entertaining hall opening into the spectacular conservatory.

Stretching across much of the rear elevation, the conservatory enjoys wonderful views over the grounds and provides direct access to one of the home's most impressive features – a luxurious indoor leisure complex.
This outstanding space includes a heated 12-metre swimming pool, jacuzzi, gymnasium, sauna, 'his and hers' changing and showering facilities and entertaining areas, creating a private wellness retreat rarely found in residential property. The leisure complex also benefits from a ground source heat pump and an electrically operated pool cover, helping to enhance energy efficiency and reduce day-to-day running costs.

The bedroom accommodation is equally impressive. The principal suite enjoys a private balcony overlooking the grounds, together with a walk-in wardrobe and luxurious en-suite bathroom. Four further bedrooms provide generous family accommodation, including a guest suite accessed via its own staircase, offering excellent privacy and flexibility.

A self-contained annexe above the double garage provides independent living space with its own sitting room which is currently set-up as a smart cinema room, kitchen/dining room, bedroom and bathroom, ideal for extended family, guests, live-in staff or multi-generational living.

The grounds are a defining feature of The Old Tower. Extending to approximately 7.5 acres, they provide an exceptional sense of space and seclusion, with sweeping lawns, mature woodland boundaries, pond, terraces and established planting all enjoying a desirable southerly aspect. Beyond the formal gardens lie paddocks and a stable complex with tack rooms and hay store, making the property equally appealing to those with equestrian interests.

Despite its wonderfully private setting, Tewin Wood remains exceptionally well-connected. Welwyn North station provides fast services into London King's Cross, whilst Hertford, Welwyn Garden City and the A1(M) are all within easy reach.

The Old Tower represents a rare opportunity to acquire one of Hertfordshire's most distinctive country homes; a property offering architectural significance, exceptional leisure facilities, ancillary accommodation and magnificent grounds in an enviable woodland setting.

Firs Walk is a highly sought after private road in a location of high quality detached homes set in the fantastic setting of Tewin Wood. This property enjoys an elevated position and large plot well detached from its neighbours. Despite the semi rural situation the house enjoys easy access to Welwyn Garden City and its extensive shopping and leisure facilities, including John Lewis, Waitrose and the Howard Shopping Centre. It is an ideal location for those wishing to commute as Junction 6 of the A1(M) is just 3 miles away and Welwyn North, Welwyn Garden City and Hertford mainline stations all within a few minutes' drive, offering fast and frequent rail services to London Kings Cross (21 minutes).

Service Charge: £150 pa approx. (to Tewin Wood Roads Ltd).
