DREAM HOME DESIGN ARCH
 

INTRODUCTION
 

        The interiors' home design arch is 'in' hereabouts.  Arch design solutions find their way into most of Before The Architect's unique home designs. Estates and not-so-estate-sized. Outside and inside. Few limits prevail beyond design style propriety, design preference, and header or beam height.
 

        This e-article is about interior dream home design arch design solutions generally for arch designers and arch design builders. Arch design options, arch design vocabulary, and arch design latitude all form the basics for getting the best out of home designing with arches
 

BASICS

There are interior home arch designs galore in size and style and layout.
 

Modifying arches to style or adding them to dream home plans can present major boosts to home designing in most Traditional home designs and some Modern home designs, too.
 

Before The Architect is increasingly involved in interiors and exteriors designing with arches in various manners of home designing - confirming the correctness of arches included in a plans set done by others, finishing the job of accurately defining arch metrics in home plans set done by others, or adding arches to a design of others or our own.
 

Most of those arches are
 

bullet

Flattened ellipse arch
 

bullet

Segmental arch

Selected Parts of an Arch, Section in Elevation

     Comment: The parts selected are more commonly addressed in application. Going further with identification moves us into the rigors of the Classical Orders and of more formal elaboration only occasionally engaged in the last few years – while distinctive, such detail is neither for everyone, nor for every style.

     Comment: This is a better place than most to introduce considerations of regularity – proportion, harmony, regulating lines – in arches which necessarily include regularity of their attendant parts.

     While there is intolerance with any of the Order’s rules in regard to a module’s derivatives, there are at least two offsets to help us on our proportioned way – the column pedestal variously formed which can act as a kind of vertical filler between column base and a lower, usually functional level such as patios, porches, or interiors' floor level; an overriding sense to the Orders overall that the Romans and, to a lesser extent, the Greeks would have found the dicta of Vitruvius, Palladio, et al. pedantic, lacking in permission for artistic latitude.

     So one comes to the major axis itself and realizes that most of the proportion is already set by intercolumniation, or functional imperatives including lines of sight, or artfulness. To the extent that an arch’s major axis can be directly related by proportion to either subordinate columns or their spacing or both, all the better.
 
     It’s the minor axis where – less constraints of both terminal height as in an eave or ceiling and structure as in a beam – proportion can play out happily.

ARCHES NOT IN SERIES

Interiors' Arches Not in Series, Drawn Detail - Section in Elevation


 

 This resolution of interiors' arches works, in this dream home designer’s opinion, not only because
 

bullet

It mimics the exterior arches in segmental form and shallow minor axis, but also because
 

bullet

These interiors' portals are not close together physically. Finally,
 

bullet

In the style of design of the instant project,
bullet

Header height had no stylistic basis for variation and, indeed,

bullet

The regularity of interior door header height benefited desirable openness in-between larger spaces.
 

     Comment: In this instance, this dream home designer draws to-scale the basic metrics of interior arches to a home design that has substantial exterior arching. The proportions of the exterior arches – based on the dominant set at Front Of House – he takes inside.
 

bullet

Of interest, these sections were not the first drawn, which first drawn were more rounded [read: marginally longer minor axis] and regarded by the clients as in need of flattening, which flattening extended to all arches both interiors and exteriors, considering that the exterior Front Of House arch across the wide Front Porch formed the basis for all other arch proportions.
 

ARCHES IN SERIES

Interior Arches in Series, Drawn Detail, Sections in Elevation

bullet

It is the experience of Before The Architect’s designers that when arches get closer together, as in a series, as in a colonnade, it’s more salutary design to hold to the math of major:minor axes across the series.
 

bullet

Before The Architect is fond of a segmental arch at major axis:minor axis::9:1, when window heads are segmental, which is almost all the time [as opposed to the semi-circular, or Roman arch, of which clients are less fond, leaving elliptical somewhere in the middle by popular demand hereabouts].
 

bullet

If sequenced, as in a porch or arcade, segmental arches appear most regular when each is set at a given major-to-minor axis ratio, say 9:1, and all the springlines are held to a singular level, thereby offering marginally different crown heights when intercolumn distances vary.
 

bullet

The Interiors' Arches In Series pic presents the stripped-down version of layouts recently done to be sure about the preferential appearance of arches in series.
 

bullet

The context is
bullet

An 8'x38' Gallery interiors facing a 20'x38' Dining and Living area.

bullet

Front entrance is on-center.

bullet

The wider middle wall opening is set to permit full view out the far-side window wall immediately upon entrance.

bullet

The flanking openings are equal in width and the piers and abutments are equal in width.

bullet

Note that header height is less important in this instance as the 38' length will be taken up with beams above Gallery ceiling level, the Gallery height being 10' and the Dining-Living area being twice that.

bullet

The tight series of openings requires more discipline in laying out the arches. While some disproportion from the Gallery view could be tolerated, the substantially wider visual perspective from the Dining-Living area would put the lie to bad judgment.
bullet

#1 conforms both springline and minor axis based on the center arch.

bullet

#2 conforms springlines, but holds major:minor axes proportions hard to the center arch, thereby slightly lowering the flankers heights.

bullet

#3 conforms proportions as in #2, but levels the arches' apices, thereby lifting the flankers' springlines over the center's.
 

bullet

#1 and #3 fail for the same reasons - disproportion, particularly from the Dining/Living viewpoint, and understatement of the central, arched opening.
 

SUMMING UP
 

bullet

Arch's overall consequences can be
bullet

Favorable: incremental formality

bullet

Favorable: the pleasant perspective of design latitude in lieu of dogma

bullet

Favorable: unobligated opportunity for accessories and

bullet

Favorable: pleasing proportion and regularity (unless you’re clueless about proportion and regularity, in which case find someone who is not clueless to help you)
 

NAILING DOWN THE ARCH DESIGN DETAILS

Exteriors and Interiors - Arches Design Detail Table, Alphameric 


 

     Comment: The AG goes to such extents as the Arches Table, so as to provide an orderly presentation of similar features – arches – without relying on the good spirits of construction to see through to the designer’s intent and vision. Note, for example,
 

bullet

Discrete treatment of the front door arch in order to distinguish it from all other arches
 

bullet

Identical treatment of similar, lesser passage at Front Of House and Back Of House
 

bullet

Cross-reference to the Elevations as further guide to application
 

bullet

The attention even to the arching of Courtyard wall doors
 

bullet

Same springline and minor axis to the Front Porch LOH and ROH as the Front Porch FOH, even though the two sets of arches have widely dissimilar major axes, in order to provide a symmetrical frame of visual reference both from and toward the house, particularly from the house Front Porch
 

bullet

Note also, please the references to the interior doors drawn in the above Figure.
