Design Guide

Design It. Build It. Own It.

Your step-by-step guide to designing the perfect deck — from understanding your site all the way to ordering materials and breaking ground. Powered by structural intelligence that manufacturers can't offer.

01

Understand Your Site

Before picking any material, understand what you're working with. Your deck's location, elevation, soil type, and local frost line determine everything from footing depth to required engineering.

Deck type: attached, freestanding, multi-level
Ground elevation and height off ground
Soil type — affects footing diameter and depth
Local frost line depth (auto-populated by ZIP code)
Sun exposure and compass orientation
Wind and shade levels for material guidance
02

Choose Your Shape & Size

Square footage drives cost, material quantity, and structural requirements. Think about what you'll use the deck for — a grill station needs different space than a hot tub platform.

Rectangle, L-shape, wraparound, or custom
Length, width, and any extensions
Joist direction (parallel or perpendicular to house)
Cantilever allowance for overhangs
Furniture fit analysis — will your table fit?
Waste optimization for standard board lengths
03

Select Your Decking Material

This is where companies like Trex and TimberTech shine — and where StruKture adds value by letting you compare every brand side by side. We show you real collections, real colors, and real pricing without bias.

Trex: Select, Enhance Naturals, Transcend Lineage
TimberTech: EDGE Prime+, PRO Legacy, AZEK Vintage
Natural wood: Pressure-treated pine, Western Red Cedar
Climate-smart picks based on your orientation
Heat technology: SunComfortable vs Alloy Armour
Warranty comparison across every product line
04

Pick Your Color & Finish

Color choice isn't just aesthetic — it affects heat, maintenance, and how your deck complements your home. Darker colors absorb more heat but create a dramatic look. Lighter tones stay cooler and brighten the space.

14+ Trex colors across 3 collections
15+ TimberTech colors across 4 collections
Board direction: straight, diagonal, picture-frame
Standard (5.5") and wide (7.25") board widths
Color families: brown, gray, tan, red, natural
Climate factor: lighter colors for hot climates
05

Configure Railing & Stairs

Railing isn't just a safety requirement — it defines the look of your deck. From sleek aluminum and cable rail to classic wood balusters, your choice sets the tone. Stairs need proper sizing for code compliance.

Railing types: wood, composite, cable, aluminum, glass
Trex Signature Aluminum & TimberTech RadianceRail
Post style options: 4x4, wrapped, or metal
Height: 36" standard or 42" tall
Stair location, width, and landing requirements
Automatic riser/tread calculations for code
06

Add Structural Intelligence

This is where StruKture leaves manufacturer tools behind. We auto-calculate your beam sizes, post spacing, footing depths, and hardware — all based on IRC span tables and real engineering data.

Automatic joist sizing (2x8, 2x10, 2x12)
Beam recommendations based on span and load
Post sizing: 4x4 vs 6x6 based on height
Footing depth = frost line + code requirements
Simpson Strong-Tie hardware for every connection
Engineering trigger warnings (hot tubs, height, etc.)
07

Review Your Material Takeoff

Once your design is locked, we generate a complete material list — every board, joist, screw, hanger, and bracket with quantities and pricing. Export it for your local lumber yard or order directly.

Itemized material list with real SKUs
Waste factor calculated per component
Export formats: PDF, contractor sheet, lumber yard list
Compare supplier pricing (Home Depot, Lowe's, etc.)
Delivery or in-store pickup options
Running cost total updates in real-time
