What affects the number

Three things move price.

Most variation in our quotes comes from these — not from us padding the margin.

1

Size and layout

A bigger footprint costs more — but so does a complex layout in a small one. Vaulted ceilings, lofts and oversized windows all add real cost.

2

Finish level

The kitchen, bathroom and floors are where finish dollars actually show up. Our packages bundle the most-common upgrades so you can compare on like-for-like.

3

Site & services

Slopes, mature trees, narrow side-yards, and how far we need to run water, sewer and electric all affect price. We assess this on the first visit.

Financing

Most clients
refinance to build.

A garden suite typically raises your home's appraised value by 18–28%. That uplift is usually enough to finance the build via a refinance or HELOC against the main home. We can introduce you to lenders we work with regularly.

HELOC

Line of credit

Draw funds as construction progresses. Interest-only payments during the build.

Refinance

Mortgage top-up

Roll the construction cost into a new first mortgage at today's rates.

Construction loan

Draw schedule

A purpose-built loan that converts to a mortgage on completion.
