Introduction

Construction is the oldest of the Xha'Ruun engineering disciplines: settlements appear 11,500 years before the present (→ see [Volume II, Ch.01, "The Prehistoric Era"]). Over twelve millennia it was not the scale that changed but the method: the modern builder does not lay stone upon stone but grows the structure from living material (→ see [Volume VI, Ch.07, "Materials Science"]). The change looks cosmetic, but it changed everything — from the design to the service life, from the profession to the aesthetics. This chapter describes the methods, stages, and typology of modern construction, as well as its hard limits.


9.1 From Masonry to Growing

Era Method Material Duration Characteristic Form
Ancient (−12,000 – −9,200) Masonry Stone, bone Years Megaliths
Imperial (−6,200 – −2,150) Masonry, arch Basalt, marble Years Colonnades
Industrial (−1,200 – +850) Assembly, casting Steel, concrete Months Frames, towers
Transitional (+850 – +1,812) Assembly + planting Composites, titanium Months Hybrid forms
Modern (+1,812 – present) Growing Silicon-organic Months–years Organic forms

The turning point is considered +1,812 Y.E., when a load-bearing beam was first grown in Khar-Vexar (→ see [Volume VI, Ch.07, §7.9]). Within three decades growing had displaced masonry from mass construction; by +1,900 Y.E. the share of "planted" structures exceeded 80%.


9.2 Stages of Construction

The modern construction cycle resembles a gardening cycle more than a factory process:

Stage Name Duration Essence
1 Planting 1–6 days Laying the "seed" — a container with the embryo of the structure
2 Feeding 90–432 days Growth; supply of silicon-salt solution and H₂S
3 Shaping Parallel with 2 Directing growth with matrices and light stimuli
4 Awakening 30–90 days Activation of self-healing and life-support systems
5 Settlement A day Installation of equipment, Xha-Ven interfaces
6 Rejuvenation Continuous Periodic "feeding" of the living layers

The seed. Construction begins with a 2×1×0.6 m container holding the embryo of the future building — a cellular matrix, a genetic growth program, and a supply of nutrients. The seed is grown on specialized farms over 6–12 months before planting and can be stored in anabiosis for up to 20 years.

Shaping. Growth is directed in two ways: rigid matrices (frame forms around which the material spreads) and light stimuli (colonies grow toward a source of a certain spectrum, like plants toward the sun). Modern projects have almost entirely abandoned matrices: light shaping makes possible forms impossible in masonry — curved, folded, branching surfaces (→ see [Volume V, Ch.02, "Architecture"]).


9.3 Typology of Structures

9.3.1 Residential Structures

Type Floors Material Feature
Clan house 1–2 Thar-Vex-1/6 Ancestral hive, 30–80 individuals
Urban cell 3–6 Thar-Vex-6 Individual nests
Nest-tower 8–24 Thar-Vex-6/12 High-rise clusters
Underground nest −1…−12 levels Thar-Vex + mycelium Thermal stability

The clan house preserves the archaic nest structure: a central common core and six branch-sectors — a reflection of the senary organization of society (→ see [Volume III, Ch.06, "Social Structure"]). The modern cell grew out of this prototype but lost the clan rigidity.

9.3.2 Public Structures

Type Example Feature
Resonator (temple) Khar-Vexar Resonator Crystalline core, acoustic cone
Academy Academy of Khar-Vexar Multi-layered "hive of knowledge"
Hospital Hospital of the Three Species Six wings for three paradigms
Stadium Rass-Ur Arena Living amphitheater stands

The resonator is a special class of structure: a building designed as a musical instrument. Its form amplifies certain frequencies for ritual choral practices (→ see [Volume V, Ch.04, "Music"], → see [Volume I, Ch.10, "Mythology and Religion"]). The interior volume of a resonator is an exact acoustic function, not an arbitrary layout.

9.3.3 Industrial Structures

Type Material Condition
Thermonuclear station Dead materials + Rass-Thar-F Internal circuits up to 2,700 °C
Crystal farm Ven-Khal + dead frame Stable temperature gradient
Computational colony Living film The-Ven Atmosphere, radiation protection
Orbital shipyard Thar-Vex + bio-membranes Vacuum outside, life inside

Industrial structures remain the only domain where "dead" class-3 materials keep a key role — where temperatures exclude life (→ see [Volume VI, Ch.07, §7.10]).


9.4 Construction in Different Environments

9.4.1 Surface Construction

Surface construction proceeds on three continents with allowance for climate zones (→ see [Volume I, Ch.15, "Atmosphere and Climate"], → see [Volume VIII, Ch.07, "Climate Zones"]):

Zone Problem Solution
Equatorial Heat, precipitation, humidity Living ventilation, fungal roofs
Tropical Seasonal monsoons Streamlined forms, wind protection
Temperate Temperature swings Thermo-skin, geothermal circuits
Subpolar Frost, polar night Underground dwellings, stored and geothermal heat
Polar −48 °C, permafrost Fully underground construction

9.4.2 Mountain Construction

In the highlands of Kharak, Rhuval, and Vexar (up to 7,820 m, the peak of Verxan — → see [Volume I, Ch.13, "Continents"]) construction uses chiefly local stone and silicon-organic material adapted to pressure swings. The deep nests of Rhuval — settlements carved into the mass of the Raal plateau — serve simultaneously as housing, as sources of geothermal heat for thermonuclear stations, and as shelter from dust storms.

9.4.3 Marine Construction

The Moryn do not build in the terrestrial sense: their "structures" are bioluminescent colonies grown at depths down to 9,847 m (→ see [Volume VI, Ch.10, "Infrastructure"], → see [Volume I, Ch.39, "The Sentient Species Moryn"]). Joint structures at the land-sea boundary (ports, piers, Xha-Ven relays) are designed as symbiotic constructions: the carbon part grows from the land, the biophotonic part from the water, joining at a single point.

9.4.4 Space Construction

Orbital stations (24 symbiotic, → see [Volume VI, Ch.06, §6.2]) are living structures grown in vacuum from dormant embryos. Their construction is the slowest kind: the station "Khar-Oko," the largest in the Orbital Forest, grew for 240 years. Xha'Ruun crews live in conditions of partial weightlessness, so the interior volumes of stations are designed with no "up" and "down" — a unique task that never faced surface builders.


9.5 Engineering Systems

9.5.1 Foundations

The foundation of a modern building is not a concrete slab but a living root node: silicon-organic "roots" grow into the ground to a depth of 6–60 m, distributing the load on the principle of a tree's root system. In seismic zones (subduction zones along the continent margins — → see [Volume I, Ch.12, "Geological Evolution"]) the foundation is reinforced with mobile joints that damp vibrations.

9.5.2 Ventilation and Climate

System Principle Energy
Living ventilation Membrane "lung" walls Metabolism
Geothermal circuits Heat exchange with the subsurface Passive
Thermo-skin Heliothermy of pigments Solar
Photosynthetic facades Energy collection + oxygen Solar

9.5.3 Communication and Data

Every modern building is connected to the planetary Xha-Ven network through the feeding channels of the mycelium (→ see [Volume VI, Ch.03, "Xha-Ven — The Biospheric Network"]). The channels are laid simultaneously with the growth of the foundation and form part of the building's "nervous system": through them flows not only information but also nutrient solutions, making the network both a communication system and the circulatory system of the structure.


9.6 Timelines and Life Cycle

Parameter Traditional Masonry Modern Growing
Design Years Days (with the help of The-Ven)
Erection 2–10 years 90–432 days
Service life 50–100 years 400–1,200 years
Self-healing No Yes
Repair Dismantling and replacement Feeding and shaping
Disposal Demolition, waste Return to the biosphere (standard ≥96%)

Design. In the era of The-Ven (the planetary computer, → see [Volume VI, Ch.04, "Living Computation"]) the design of a building is not a drawing but a genetic growth program, computed by a computational colony within hours. The architect (→ see [Volume V, Ch.02]) describes not the form but the behavior: how the building should grow, breathe, age.

Rejuvenation. Once every 30–60 years a living building is "rejuvenated": feeding is intensified, dead sections removed, the growth of new layers directed. With proper care the service life can exceed 1,200 years; the oldest modern building — the Hospital of the Three Species in Khar-Vexar (+2,010 Y.E.) — has been in active service for more than two thousand years (→ see [Volume VI, Ch.08, "Medicine"]).


9.7 The Lost and the Forbidden

History has preserved the experience of loss as well. The Crisis Era (−2,150 – −750) destroyed the imperial construction tradition: the secrets of masonry of large spans and hydraulic structures were lost (→ see [Volume II, Ch.04, "The Era of Crisis"]). Restoration took centuries.

Modern construction prohibitions:

Prohibition Reason
Buildings above 24 floors (surface) The honesty-of-material standard, aerodynamics
Construction in active seismic zones Risk to life
"Dead" monoliths in residential areas Lack of self-healing
Structures with nervous tissue Ethical code of the Guild of Engineers
Growing structures for biological weapons The Treaty of the Three Species

Surface height limits reflect strength, access and rescue capacity. Gradual material change can warn of structural damage; fire and sudden impact require independent escape routes. The 24-floor rule belongs to surface construction standards, not to a universal evacuation countdown.


9.8 The Aesthetics of Living Construction

The aesthetics of modern construction is shaped not by architectural fashion but by technology (→ see [Volume V, Ch.02, "Architecture"]):

Critics of the direction point to the other side: living buildings require constant care, are sensitive to temperature swings, and "fall ill" — and the illness of a building is literally visible in its color. Maintaining a structure has become a profession known as the building keeper — a hybrid of architect, gardener, and physician.


Chapter Summary

  1. Modern construction is not masonry but growing: a building is "planted" as a seed, grown for 90–432 days, and maintained as a living organism.
  2. Form is set by light shaping and a genetic growth program, not by drawings; the architect describes behavior, not form.
  3. Living buildings self-heal, serve 400–1,200 years, and return ≥96% of their mass to the biosphere upon disposal.
  4. Construction is bounded by the "honesty of material" standards and the ethical code: a maximum of 24 floors on the ground, a ban on structures with nervous tissue.
  5. The aesthetics of living construction — organic forms and senary symmetry — gave rise to the profession of the "building keeper."
