Regions we cover
LINX Design & Build takes on architecture, planning, extensions, loft conversions, renovations and new builds across Bristol, Bath and the surrounding area, including South Gloucestershire and North Somerset. One in-house team designs each project, secures approval from the relevant council and builds it, starting with a free survey and a fixed-price quote.

Design & build
Bath is unusual in England: the whole city is a UNESCO World Heritage Site, and a high share of its buildings are listed, so even modest changes often need listed building consent as well as planning permission from Bath and North East Somerset Council. Permitted development for loft conversions and side extensions does not apply anywhere in the World Heritage Site.
Bristol City Council covers a hilly city of Georgian terraces in Clifton and Hotwells, Victorian villas and terraces in Redland, Cotham and Bishopston, and interwar suburbs beyond, while South Gloucestershire and North Somerset councils cover towns such as Thornbury, Yate, Portishead and Clevedon. The Bristol and Bath Green Belt separates the two cities, and the Cotswolds and Mendip Hills National Landscapes lie close by.
Bath is defined by Georgian terraces, crescents and villas built in honey-coloured Bath stone, many of them listed, alongside Victorian suburbs such as Oldfield Park, where terraces suit rear dormers and kitchen extensions with planning permission. Bristol's Clifton and Hotwells have Georgian and Regency terraces, Redland, Cotham and Bishopston have Victorian villas and bay-fronted terraces, and Southville and Bedminster have smaller Victorian terraces. Westbury-on-Trym, Stoke Bishop and the outer suburbs add interwar semis and detached houses suited to larger extensions and hip-to-gable lofts.
Our services
Our architects design for Bath stone terraces, Clifton's Georgian streets and Bristol's Victorian suburbs, where materials and proportions are closely scrutinised.

Find out more 04Rear dormers suit terraces in Bishopston, Southville and Bedminster, often under permitted development; anywhere in the City of Bath, and in Bristol's conservation areas, a loft conversion needs planning permission.

Questions
In most cases, yes. The whole City of Bath is a UNESCO World Heritage Site, which removes permitted development for loft conversions, side extensions and cladding, and many Bath homes are listed, so listed building consent is needed for alterations affecting their character, inside or out. Much of the city is also a conservation area. A single-storey rear extension within the standard limits may still be permitted development on an unlisted house.
Usually, yes. A rear dormer on a terraced house in Bishopston, Southville or Bedminster can often be permitted development, adding up to 40 m³ of roof volume, provided it stays off the front roof slope, uses similar materials and the street is not in a conservation area. Shared walls mean the Party Wall etc. Act 1996 usually applies, and flats need planning permission. We confirm the right route with Bristol City Council first.
Yes, but expect a planning application. Most of Clifton lies within the Clifton and Hotwells conservation area, where side extensions and the larger prior-approval rear extension are not permitted development, and many houses are listed or divided into flats, which need planning permission and, for listed buildings, listed building consent. Bristol City Council will look closely at materials, proportions and views. We design extensions that respect the Georgian and Victorian setting.
We price each Bristol and Bath project individually and give a fixed-price quote after a free survey. The cost depends on the design, the existing structure, access, drainage and the specification. Local factors, such as natural Bath stone, specialist repairs to listed fabric, steeply sloping Bristol plots or limited access to a city terrace, are included in the quote from the start rather than added later.
Householder planning applications and listed building consent applications both have an 8-week statutory determination period from validation, and for listed homes they are usually submitted together. Applications in Bath's World Heritage Site or Bristol's conservation areas can take longer if the council requests design changes. Prior approval for a larger rear extension, where it applies, is decided within 42 days. We confirm the build programme once approvals are in place.
We take on projects across Bristol, Bath and the surrounding area, including Clifton, Redland, Cotham, Bishopston, Southville, Westbury-on-Trym and Stoke Bishop in Bristol; Bath, Keynsham and Midsomer Norton in Bath and North East Somerset; Portishead, Clevedon and Nailsea in North Somerset; and Thornbury and Yate in South Gloucestershire. Every project begins with a free survey and a fixed-price quote.
