SDA Heritage focuses on the recording, restoration, regeneration, and development of historic buildings. We always aspire to have a deep understanding of the places, people, and the context of the buildings we work with to create designs and solutions that are both holistic and sustainable.

 

Our expertise in conservation pairs perfectly with our ability to design conscientiously, as well as our skills in the surveying of heritage structures. SDA is able to offer a full restoration design service from the initial survey and recording of the historic structure, through to the handover of the building to the client post-construction phase.

Doddington Hall Estate
DJI_0049_edited.jpg

Steven Dunn Architects are delighted to have been working with Doddington Hall since 1996 on various projects within the Estate; These range from residential, commercial, to general repairs and conservation work to the Grade II* Listed Hall Building itself. 

 

Doddington Hall was built between 1593 and 1600, and likely designed by Robert Smythson. The Hall is now open to visitors with a vast array of shops, restaurants, and countryside walks.

Ashby Hall

Ashby Hall was originally built in 1595 and has since undergone numerous changes/additions. After the new owner's acquisition of the property in the early part of 2017, Steven Dunn Architects were assigned as the Architects for the project with the intended brief to revitalise and reinvigorate the derelict site and in essence, restore the hall to its former grade listed self.

Prior to the new tenure, the premises have, for a number of years, suffered from a general lack of maintenance, relating in general to a lack of adequate funding being available to meet the (very substantial indeed) costs of maintaining a property of this type. In addition, over the last 30 or 40 years, the property has been subjected to a series of (often very) insensitive alterations which have severely affected both the character and the fabric of the original Listed building.

Steven Dunn Architects' role within this project include:​

  • A complete redesign of the Hall's interior

  • The introduction of a Grand Hall

  • The introduction of an Orangery

  • An overall cleaning (and in some cases reconstruction) of the external stone walls

  • The management of cleaning the entirety of the lake

  • The re-roofing and general refurbishment of the Hall's Stables

  • Oversee and specify demolition and construction works

  • 3D Point Cloud Scanning/ Photogrammetry Surveys

  • 3D Modelling of the entire Hall from Point Cloud survey to produce drawings and visuals

Osberton Hall

Osberton Hall is an 18th Century country house which was substantially remodelled and extended in the 19th Century. SDA were pleased to be engaged on the existing owners in 2013 to survey the existing building and design a new pool building and garage, and we have been re-approached in 2024 to oversee the re-roofing works to the property.

Washingborough Hall

Washingborough Hall is a Grade II listed building and is currently used as a Hotel. In 2016, SDA were approached by the owner to design a sympathetic and in-keeping extension to provide additional function space and facilities.

Harmston Hall

Over a period of some 20 years, SDA were involved in a number of Listed Building Applications for works of improvement to the (then derelict) Hall. Prior to the sale of the property in 2020, SDA were pleased to assist the (then) owner in the preparation of retrospective Planning & Listed building consent applications for a number of alterations which had been carried-out to the property. We were delighted to see the huge improvement in the quality of the building in our 20 year involvement and are thrilled to still be working with the (now) previous owner on his new home for around 5 years.

SDA were pleased to be commissioned to up-to RIBA Stage 4 to provide multiple minor amendments to the internal layout of the 18C Grade II Listed Manor House. At ground floor level, the proposal involved the minor removal of later addition internal walls to create scope for a more appropriately sized utility area and WC to suit the large scale of the home. A garden room was  proposed on the south elevation of the property adjoined to the kitchen. The purpose of this extension was to create a dining area which could be directly linked to the kitchen and suit the demands of modern living. The addition of the garden room required the eaves level of the existing porch to be lifted. At first floor level, an small extension above the existing store room was proposed to create a dressing room and en-suite to one of the family bedrooms. SDA were pleased to obtain a Planning Approval for these works from NKDC in August 2021.
