Multi-Generational Homes in Langley

Thoughtfully built homes for families who want to live close — with the privacy, dignity, and ease that every generation deserves.

Overview

Three generations under one roof — done well.

Across the Township and City of Langley, more families are choosing to build homes that house parents, grown children, and grandchildren on a single property. Done well, these homes ease the cost of childcare and aging in place, deepen family bonds, and create generational wealth that stays in the family.

Customline Homes specializes in multi-generational builds across Langley — from coach houses and secondary suites to full duplex-style residences with separate entrances, kitchens, and outdoor spaces. We know the local zoning, we know the lots, and we know how to design for households that need both togetherness and privacy.

Why Langley

Langley offers some of the most progressive zoning in the Lower Mainland for multi-family living on a single lot. With provincial small-scale multi-unit housing legislation in force and the Township's secondary suite and coach house programs well-established, the region is uniquely suited to thoughtful multi-generational design.

i.

Lot Sizes That Work

Walnut Grove, Willoughby, Brookswood, Murrayville, and Fort Langley offer the lot depth needed for a primary home plus a detached coach house — without crowding either dwelling.

ii.

Supportive Zoning

Provincial Bill 44 and Langley's small-scale multi-unit housing bylaws allow up to three or four units on most single-family lots, with coach house provisions in many neighbourhoods.

iii.

Family-First Community

Strong schools, parks, transit corridors, and healthcare access — built for families that span generations and want to stay close.

iv.

Long-Term Value

A well-designed multi-gen build retains rental flexibility, accommodates aging in place, and increases resale appeal in one of BC's strongest growth corridors.

Home Types

Every family is different. We build three principal configurations — and combinations of each — to fit your lot, your bylaws, and the rhythms of your household.

01 / Coach House

Detached Coach House

A self-contained second dwelling on the same lot as the primary home. Ideal for adult children, parents, or extended-stay family — with its own entrance, kitchen, and yard space.

  • Up to ~970 sq ft (varies by zone)
  • One or two bedrooms, full kitchen, laundry
  • Optional rental income when not in family use
  • Separate utilities and metering
02 / Secondary Suite

In-Home Suite

A legal secondary suite woven into the primary home — designed with privacy in mind. A favourite for aging parents who want the security of family nearby without sacrificing independence.

  • Ground-level or above-ground walk-out
  • Single-level living for accessibility
  • Separate entrance and laundry
  • Soundproofed party walls and floors
03 / Full Multi-Gen Build

Multi-Gen Residence

A purpose-built home with two or three fully independent wings, often sharing a courtyard, mudroom, or great room. The most ambitious option — and the one that best preserves dignity for every generation.

  • 2–4 independent suites, shared common spaces
  • Universal design principles for aging in place
  • Acoustic and visual separation by design
  • Single architectural language, multiple front doors
Zoning & Bylaws

A quick overview of what's currently permitted across Langley. Final feasibility always depends on lot size, frontage, servicing, and the specific zone — we'll walk you through it on your site.

Township · R-1

Single-Family Lots with Coach House Potential

Many R-1 lots in Willoughby and Walnut Grove permit a primary residence plus a detached coach house, subject to lot size and corner-lot exceptions.

Township · SR-2 / SR-3

Suburban Lots for Multi-Gen

Larger Brookswood and Murrayville lots can often support a primary home, in-home suite, and a coach house — making them ideal for three-generation households.

City · RS / RDS

City of Langley Residential

Most residential lots in the City of Langley now permit secondary suites by right under provincial small-scale multi-unit housing legislation. Duplex and triplex configurations are available on qualifying lots.

Heritage · Fort Langley

Fort Langley Heritage Conservation

Multi-gen builds within the Fort Langley Heritage Conservation Area require additional design review. We've navigated this process before — and we'd happily walk you through what's possible.

Common Questions
How long does a multi-gen build take in Langley? +
From permit application to handover, plan on 14–22 months. Coach houses on existing properties move faster (often 9–12 months once permits are issued); full multi-gen new builds take longer due to the additional design and servicing coordination.
Can the second dwelling be rented when family isn't using it? +
In most Langley zones, yes — legal coach houses and secondary suites can be rented when not occupied by family. This often makes the build financially sustainable across changing family needs.
Do you design for aging in place? +
Always. Zero-threshold showers, wider doors, lever hardware, single-level living, blocking for future grab bars, and considered lighting are built in from the start — without making the home feel clinical.
How do you handle privacy between suites? +
We treat acoustic and visual separation as a first-order design problem: separate entrances, staggered window lines, double-stud party walls with resilient channels, decoupled floor assemblies, and exterior courtyards that give each generation its own outdoor space.
What's a realistic budget? +
Coach houses in Langley typically begin around $450K all-in; full multi-gen residences start in the high seven figures and scale with site, finish, and program. We provide a transparent budget before construction begins.
Can you work with our existing architect? +
Absolutely. We collaborate with your team or recommend trusted partners we've worked alongside on multi-gen builds across the Township and City.
