Engineer your build with precision.

Describe what you want to build or remodel. BuildStack helps you discover the right materials and assemblies for your space.

Architectural Intelligence Platform

Engineered for Precision Construction & Specification

Every material recommendation, acoustic calculation, and multi-tier assembly is strictly grounded in manufacturer technical data and certified European building standards.

Vector Embeddings + BM25

Hybrid Catalog Search & Parametric Filters

Combines high-dimensional dense vector embeddings (pgvector) with lexical keyword matching. Search by conceptual queries (e.g. "moisture-resistant ceiling for walk-in shower") or exact product codes, with instant filtering across fire ratings (EI 30–120) and acoustic decibel ratings.

3-Tier Solution Plan Generator & BOM Builder

Instantly engineers 3 distinct certified system assemblies: Budget Option, Balanced Standard, and Premium High-Performance. Each option delivers a complete bill of materials, estimated cost per m², acoustic ratings, and layer-by-layer specifications.

Tier 1Budget

Essential Compliance

Value-engineered base build-up

Tier 2Balanced

Commercial Standard

Optimal acoustic & moisture balance

Tier 3Premium

Maximum Performance

Heavy acoustic mass & resilience

Deterministic Physics & Math

Deterministic Tools for Dynamic Queries

Rather than relying on speculative LLM estimates, BuildStack invokes deterministic calculation tools for exact framing bills of materials, acoustic mass-air-mass formulas, and certified fire ratings tailored to dynamic room dimensions.
