Custom Home vs. Spec Home: Which is Right for You?

Written by London Bay Homes | January 19, 2026

A custom home is built entirely around your preferences, while a spec home is built in advance with pre-selected designs and finishes. While custom homes offer unmatched flexibility and personalization, spec homes provide the benefits of faster move-in timelines and more predictable pricing, making them a convenient option for buyers who want a new home without the lengthy design process.


What is a Custom Home?  

A custom home is designed and built specifically for the buyer. Homeowners work closely with the builder throughout the design and construction process to ensure every detail aligns with their vision. This collaborative approach allows for a truly unique home that meets your exact specifications.

Customization typically includes:

  • Lot selection: Choosing the location and setting that fits your lifestyle
  • Floor plans: Bedrooms, ceiling heights, window placement, and spatial flow
  • Exterior materials: Stone, brick, and architectural finishes
  • Interior selections: Flooring, cabinetry, lighting, plumbing fixtures, and finishes


What is a Spec Home? 

A spec home, short for “speculative home,” is built without a specific buyer in mind. Builders design these homes to appeal to a broad audience and often complete them before a buyer is identified.

While some spec homes allow buyers to make a few selections if purchased during construction, the level of customization is generally limited compared to a custom home. The advantage of a spec home lies in its convenience: buyers can often move in sooner, and pricing tends to be more predictable since most design and construction decisions have already been made.

 

WHat is the Difference Between a Custom and Spec Home?

Customization 

With a custom home, home buyers have complete control over its design, whether the architecture, floor plan, material, or finishes. With a spec home, the builder predetermines the home's overall design with minimal chances for the buyer to make changes according to their taste. 

Cost 

Custom homes are usually more expensive since they allow unlimited customization to tailor them according to the buyers' refinement. Though expensive, they're worth every penny, considering they offer your desired lifestyle. For a spec home, costs are more affordable since builders construct them according to their design and usually construct several at once in a single development. 

Timeline

Building a custom home may take longer to complete based on the complexity of the desired design. It also takes longer to acquire the necessary building permits and conduct inspections. With a spec home, developers usually have the necessary licenses, which speed up the construction process.
