The proposal is also located within the Snettisham Conservation Area which was designate in 1978 with Conservation Areas as a concept established in 1967 under the Civic Amenities Act.

​

Snettisham has a rich history that spans several centuries. Archaeological evidence suggests that Snettisham has been inhabited since prehistoric times. The area was settled by Iron Age tribes, and the discovery of the Snettisham Hoard in the late 1940s highlighted the region's significance during the Iron Age. The hoard consists of several hundred gold and silver objects, including torcs (neck rings), bracelets, and coins, dating back to around 70 BCE. During the Middle Ages, Snettisham was an agricultural village, with a focus on farming and fishing. It had a manor house and a small community. The village was mentioned in the Domesday Book of 1086, a survey commissioned by William the Conqueror, where it was recorded as "Snetesham." The Church of St. Mary in Snettisham has medieval origins, with the oldest parts of the church dating back to the 13th century. It underwent various renovations and additions over the centuries. The church played an important role as a religious and social center for the community.  Due to its coastal location, Snettisham had connections to maritime activities. In the 17th and 18th centuries, it was involved in the local fishing industry, with boats venturing out to The Wash for catches. Additionally, the village had a history of smuggling during the 18th and early 19th centuries. In the 19th century, Snettisham witnessed various developments, including the construction of a railway line that connected King's Lynn to Hunstanton. This improved transportation links and facilitated the movement of goods and people. The railway line operated until the mid-20th century.

Today, Snettisham retains its character as a coastal village with a strong sense of community. It attracts visitors due to its natural beauty, including the RSPB Snettisham Nature Reserve, which is renowned for birdwatching and conservation efforts. The village's historical significance, particularly related to the Snettisham Hoard, adds to its cultural heritage.

 

The Planning Appraisal

​

The planing application is for the conversion of an existing outbuilding (part of a range) to use as a studio, including the renovation and repair of the walls and loft access, plus the construction of a small porch on the front of the existing cottage. The ground floor is to comprise a bathroom and utility room with stairs up to a studio at first floor. The accommodation is intended to be used in conjunction with the main modest cottage and not as a separate unit of residential accommodation. This may be controlled via condition.

Given the scale of the main dwelling and the position of the outbuilding in relation to it, with a shared access and garden area to the rear, the proposed ‘studio’ is considered to comply with Policy DM7 of the SADMPP (2016). Conditions are recommended to link the studio to the donor dwelling for the avoidance of doubt.
The porch proposed over the front door will replicate a similar addition to a neighbouring cottage on this road frontage.

This scheme has been the subject of negotiation with the involvement of the Conservation Officer. These alterations to both the outbuilding and new porch are the subjects of an application for Listed Building Consent which were  dealt with separately via a Listed Building Consent Application.

​

The proposal involves the conversion of an existing building and given its location and limited alterations, the proposal is considered unlikely to lead to any adverse impact on the amenity of adjoining properties. The replacement of the loft door with a full height window would not create adverse implications regarding overlooking to neighbours due to existing outbuildings and planting which affords privacy to adjoining cottage yards.

The rear elevation directly abuts the adjoining builders’ merchant stores and buildings. Existing openings are to be re-used and there are no implications regarding amenity issues as there are effectively no changes to the present uses.

Other material impacts: No – as the LHA states, the access width and visibility is limited by the frontage walls allowing restricted levels of visibility onto the Hall Road whilst being of a width unsuitable for two way vehicle movements, which would be considered unsuitable to serve additional units/increased vehicle activity associated with independent occupation/use of the building, separate from the main dwelling. Once again a condition can be used to ensure the building remains ancillary to the main dwelling.
Specific comments or issues:

The proposal is a sensitive repair and use of an existing outbuilding in a manner that respects its listed status and accords with the provisions of the NPPF and Policies CS01, CS06, CS08, CS11 & CS12 of the Core Strategy (2011) and Policies DM1, DM2, DM7, DM15 & DM17 of the SADMPP (2016), plus Policies NP05, NP07 & NP08 of the Neighbourhood Plan. The application

​

En-Plan have worked in conjunction with the District Council's Planning Department to address concerns raised by the Council's Conservation Officer in the planning process as the application  site is also located on the edge of the Snettisham Conservation Area En-Plan need to formulate a sensitive scheme that would not harm the area.  This was done by providing a Heritage Statement which showed the development would have no detrimental impacts on the historic environment, and with this knowledge the Council were able to approve both the planning and listed building consent applications.

En-Plan: Planning & Architecture have been instructed by Mr. Rick Wilson to produce and submit a Planning and Listed Building Consent Application for the extension of an existing outbuilding and its conveersion to a rsidnetial annex. A Heritage Statement was subvmitted with the application to demonstrate how the application is fully planning policy compliant and how the scheme will preserve and enhance the character and setting of the locality.

 

The site forms part the Snettisham Conservation Area and is adjoined on both sides by existing development with Hall Road located to the fore.  To the rear of the site is a builders yard. The applicants are looking to add a new home office and a guest bedroom in order to make the best use of the current outbuilding and add a new storage room in a new extension that partly utilises the existing wooden log store.

 

 The application site is residential in character. The existing outbuilding is located to the rear of the main property and is well screened by existing development. The site has always been a domestic unit. Hall Road is located to the front of No.17 and is accessed off an existing drive to the rear. The houses are all small domestic units and either terraced or semi-detached in nature which front onto Hall Road. The work is to covert and sympathetically extend the existing building so looks to work within the scale and mass of the existing outbuilding, with the addition of a modest extension. The proposed extension will not form an overbearing extension in relation to adjoining units or erode levels of residential amenity in the locality. 

 

With regard to the materials used the applicants will liaise with the Council to ensure the materials used and windows and door frames proposed meet the high standards expected in a Conservation Area, With the above mitigation strategy the proposal will preserve and enhance the setting of the locality. The proposal has been judged to preserve this historic building for future generations and thereby preserves and enhances the Snettisham Conservation Area.
