Architectural barn conversion with pool, annexe and fast commuter access to London King’s Cross.

Description
Architectural barn conversion with pool, annexe and fast commuter access to London King’s Cross.

Set behind electric gates within beautifully landscaped gardens, this exceptional 17th-century barn conversion combines contemporary architectural living with outstanding London connectivity. Welwyn North station is approximately five minutes away by car, with frequent fast commuter services reaching London King’s Cross in approximately 19 minutes during peak hours.

Extensively redesigned and refurbished throughout, the property offers over 3,500 sq ft of highly flexible accommodation across the principal barn and detached self-contained annexe. The interiors have been thoughtfully curated to create a calm, design-led environment ideally suited to modern hybrid working, entertaining and flexible family living.

The principal reception space is particularly striking, featuring dramatic double-height vaulted ceilings, full-height glazing overlooking the gardens and heated pool, and a double-sided log-burning fireplace connecting seamlessly to a more intimate snug area. Natural light floods the space throughout the day, creating a relaxed yet highly sociable atmosphere. A galleried mezzanine, currently arranged as a dedicated home office, further enhances the architectural feel of the home and creates an inspiring hybrid-working environment.

The contemporary kitchen by 1909 features waterfall granite worktops, Quooker tap, chef’s pantry, dual dishwashers and integrated high-specification appliances, designed equally for everyday family life and large-scale entertaining.

The main barn provides three bedrooms arranged across two levels, including a beautifully appointed principal suite with freestanding bath, dressing area and air conditioning. A further ground-floor bedroom suite offers additional flexibility for guests, live-in support, visiting family or alternative principal accommodation.

The detached annexe provides exceptional versatility and is ideally suited as guest accommodation, executive workspace, creative studio, wellness suite or semi-independent living for older children or extended family. The annexe includes two en suite bedrooms, air conditioning, utility/laundry room and an open-plan kitchen/living space.

Externally, the grounds have been designed for both relaxation and entertaining, centred around a heated swimming pool with electric safety cover and landscaped gardens offering a high degree of privacy. A newly designed terrace creates seamless indoor-outdoor flow during the warmer months, while extensive exterior lighting transforms the gardens in the evening.

Location
Datchworth is one of Hertfordshire’s most desirable village settings, combining countryside surroundings with excellent access into London. The property is particularly well suited to buyers connected to the King’s Cross technology, life sciences and knowledge corridor, offering the ability to balance fast London access with a more relaxed architectural lifestyle setting.

Fast commuter services from Welwyn North to King’s Cross operate approximately every 30 minutes during peak commuter periods, with journey times of around 19 minutes. Frequent services continue throughout the day with typical journey times of approximately 34 minutes.
