A sumptuously stylish transformation at 1 Bishop Court, Sefton

Case Studies, General

Architect Nick Serridge and chartered surveyor Paul Ennis have helped to refurbish and extend a traditional Elizabethan style house located in an upmarket area of Formby. The stunning results of this transformation show how innovative design can successfully combine architecture from two different eras.1 Bishop Court, Sefton

Owner Mr Dorrity’s ambitious vision for this large two-storey property included replacing the roof, creating a luxurious master bedroom and bathroom and adding ensuites to the existing bedrooms. He also wanted to alter the property’s layout on both levels and add two ground floor extensions. The rear extension would increase the size of the lounge, while the side extension would become a light and airy orangery.1 Bishop Court, Sefton

Mr Dorrity appointed architect Nick Serridge to design his dream home and chartered surveyor Paul Ennis to construct it. An approved LABC partner, Paul built on his excellent relationship with Sefton Building Control by submitting detailed plans early on. This proved very useful when there was an issue with the approved fire regulations.

Complying with the regulations would have meant fitting glazed doors to the property’s lounge and kitchen diner. However, Mr Dorrity was strongly against this, as he was keen for the entire building to have a light, spacious feel.

To find a solution that would meet safety requirements and please his client, Paul Ennis held early talks with Sefton Building Control. These resulted in a fire detection and alarm system being installed throughout the property, as well as fire doors on the new first and second storey rooms opening onto the stairwell. Every room was also fitted with an escape window or door.

The interior of this impressive property reflects its owner’s focus on top quality materials and excellent workmanship. Oak is used throughout, linking the old and new parts of the building and providing a striking contrast with the crisp white walls and white marbled floors.

The oak glazed façade to the entrance hall and landing matches the oak framed rear extension and the internal woodwork is also oak. Then there’s the star of the show; a stunning floating oak staircase.

An equally luxurious feel has been given to the new master bedroom and its adjoining bathroom, which features its own balcony. According to Mr Ennis, “lying in the bath with the peaked window to the front, balcony doors to the rear and sleek white décor must provide the occupant with the sense that they are in a high end exclusive hotel.”

Sustainability was an important consideration when it came to extending 1 Bishop Court. Early on in the process, Paul Ennis submitted structural and carbon emission calculations to Sefton Building Control and these were passed.

As the side extension would feature a large glazed area, owner Mr Dorrity agreed to install a new heating system and to add new double glazing to all existing rooms. The insulation in some of the walls also needed upgrading and the thickness of the roof insulation had to be increased. The new rear extension already included cavity wall insulation and a stylish roof light allowed natural light to flood into the room.1 Bishop Court, Sefton

The transformation of 1 Bishop’s court was certainly a challenge, but the excellent relationship between Paul Ennis, his client and Sefton Building Control has resulted in a stunning property that stands out from the crowd.

According to Mr Ennis: “I can well imagine that there are some envious neighbours now looking at their properties in a different way and secretly hating what has been created!”1 Bishop Court, Sefton
