Architectural Design Guidelines – Specific RecommendationsElevation design plans involving NEWCONSTRUCTION should incorporate thefollowing design recommendations, asapplicable:Additions to Historic Buildings• Minimize the loss of historic fabric and ensure thatcharacter-defining features of the historic building arenot destroyed, damaged, or obscured.• Retain the overall character of the site, sitetopography, character-defining site features, trees,and significant district vistas and views.• Protect large trees and other significant site featuresfrom immediate and delayed construction damage.• Limit the size and scale of an addition to avoiddiminishing or visually overpowering the historicbuilding.• Design to be compatible with the historic building inmass, materials, color, and the relationship of solidsand voids to exterior walls, yet make the additiondiscernible from the original.Actions that are inconsistent with establishedpreservation goals and should be avoided include:²²Constructing an addition that detracts from theoverall historic character of the principal buildingand the site, or requires the removal of a significantelement or site feature.²²Constructing an addition that significantly changesthe proportion of built mass to open space on anindividual site.New Construction• Site new construction to be compatible with theoverall character of surrounding buildings and thehistoric district in terms of setback, orientation,spacing, and distance from adjacent buildings.• Preserve the overall character of the site, sitetopography, character-defining site features, trees,and significant vistas and views.• Protect large trees and other significant site featuresfrom immediate and delayed construction damage,such as loss of root area and compaction of the soilby heavy equipment.• Design the height, form, size, scale, massing,proportion, and roof shape to be compatible with theoverall character of surrounding buildings and thehistoric district.• Design the proportion of the proposed new building’sfront façade to approximate the front façadeproportion of surrounding historic buildings.• Design the spacing, placement, scale, orientation,proportion, and size of window and door openingsto be compatible with the overall character ofsurrounding buildings and the historic district.• Select windows and doors with material, subdivision,proportion, pattern, and detail compatible with thewindows and doors of surrounding buildings and thatcontribute to the character of the historic district.• Select materials and finishes compatible with thematerials and finishes of surrounding buildings interms of composition, scale, module, pattern, detail,texture, finish, color, and sheen to contribute to thecharacter of the historic district.• Design new buildings to be compatible with, butdiscernible from, historic buildings in the district.Elevation design plans involving REPAIRAND REPLACEMENT of exterior buildingfeatures should incorporate the followingrecommendations, as applicable:Wooden Architectural Features• Retain and preserve wooden features that contributeto the overall historic character of a building andits site, including such functional and decorativeelements as siding, shingles, cornices, architraves,brackets, pediments, columns, balustrades, andarchitectural trim.• Use recognized preservation methods for patching,consolidating, splicing, and reinforcing.24 Section 3: ARCHITECTURAL DESIGN GUIDELINES Mississippi Development Authority ELEVATION DESIGN GUIDELINES
• Replace only deteriorated details or elements inkind, rather than replacing entire features. Matchthe original detail or element in design, dimension,texture, and material. Consider compatible substitutematerials only if using the original material is nottechnically feasible.• Replace missing features with equivalent features,based on accurate documentation of the originalfeature, or a new design compatible in scale, size,material, texture, and color with the overall characterof the building and historic district.• Repaint wooden surfaces and features in colors thatare appropriate to the historic building and district.• Clean wooden architectural features using gentlemethods such as low-pressure washes with detergentsand natural bristle brushes. Chemical stripping maybe used only if gentler methods are ineffective.Actions that are inconsistent with establishedpreservation goals and should be avoided include:²²Cleaning wooden features and surfaces withdestructive methods such as sandblasting and powerwashing, or using propane or butane torches.²²Stripping painted surfaces down to bare wood andapplying clear stains or finishes to create a naturalwood appearance.²²Replacing sound, painted wooden siding with newsiding to achieve a uniformly smooth wooden surface.²²Replacing or covering wooden siding, trim, or windowsashes with contemporary substitute materials suchas aluminum or vinyl.²²Introducing wooden features or details to an historicbuilding in an attempt to create a false sense ofhistorical appearance.Masonry• Retain and preserve, as practicable, masonry featuresthat contribute to the overall historic character ofa building and a site, including walls, foundations,roofing materials, chimneys, cornices, quoins, steps,buttresses, piers, columns, lintels, arches, and sills.• Protect and maintain historic masonry materials,such as brick, terra-cotta, limestone, granite, stucco,slate, concrete, cement block, and clay time, andtheir distinctive construction features, includingbond patterns, corbels, water tables, and unpaintedsurfaces.• Use recognized preservation methods for piecing-in,consolidating, or patching damaged or deterioratedmasonry surfaces.• Repoint masonry mortar joints if the mortar iscracked, crumbling, or missing, or if damp walls ordamaged plaster indicate moisture penetration.Before repointing, carefully remove deterioratedmortar using hand tools. Replace the mortar with newmortar that duplicates the original in strength, color,texture, and composition. Match the original mortarjoints in width and profile.• Replace only the deteriorated portion of a detail,module, or element of a masonry surface or featurein kind rather than replacing the entire surface orfeature. Consider compatible substitute materialsonly if using the original material is not technicallyfeasible.• Replace large masonry surfaces or entire features, ifnecessary, in kind, matching the original in design,detail, dimension, color, pattern, texture and material.Consider compatible substitute materials only if usingthe original material is not technically feasible.• Replace missing masonry features with equivalentfeatures, based on accurate documentation of theoriginal feature, or a new design compatible in scale,size, material, and color with the overall character ofthe building and historic district.• Test any cleaning technique, including chemicalsolutions, on an inconspicuous sample area well inadvance of the proposed cleaning to evaluate itseffects. Cleaning masonry features with destructivemethods, including sandblasting, high-pressure waterblasting, and power washing is not appropriate.• Repaint previously painted masonry surfaces in colorsthat are appropriate to the historic material, building,and district.Actions that are inconsistent with establishedpreservation goals and should be avoided include:²²Applying a waterproof coating to exposed masonryrather than repairing it.²²Painting previously unpainted masonry surfaces.Mississippi Development Authority ELEVATION DESIGN GUIDELINESSection 3: ARCHITECTURAL DESIGN GUIDELINES25
