Residential Design and Construction
The Great Room Company presents a regional residential design-and-build practice with contact locations in Newburyport, Massachusetts, and Portsmouth, New Hampshire. Its portfolio spans new houses and changes to existing homes, with separate galleries for waterfront properties, featured homes and additions or renovations.
The published projects give prospective clients a way to assess architectural character and the relationship between a house and its surroundings. Examples range from cottage and shingle-style homes to more contemporary forms. The gallery is useful evidence of the company’s presented work; it does not establish the scope or price of a future commission.
Design Visualisation and Project Examples
The official CAD to Finished Home collection places design images alongside finished photographs. Dramatic Arches and Shingle Style are two named examples. This lets a visitor compare the proposed building form with the completed result rather than relying on drawings alone.
For alteration work, the company states that it has in-house design staff and framing crews. Its renovation gallery includes Island View, The Wave Addition and Traditional Revisited. These examples help homeowners explore how additional living space can relate to the existing building. Staff numbers, facilities and construction licences have not been independently established in this Phase 1 review.

Siachen Reader Note
Business information naturally evolves over time as organisations introduce new products, services, facilities, technologies, certifications, leadership changes and operational improvements.
This Business Knowledge Profile begins with information submitted by the business owner or representative. Siachen then reviews, verifies where possible, and enhances that information using the company’s official website, where available, and other reliable public sources before publishing the revised profile.
As business information may change after publication, readers are encouraged to visit the company's official website, where available, or contact the business directly to obtain the latest information regarding products, services, pricing, operating hours, admissions, appointments, certifications, contact details, locations and other important updates before making business decisions.
Siachen Business Knowledge Platform periodically reviews Business Knowledge Profiles wherever practical. However, the official website, where available, and authorised representatives of the business remain the most reliable sources of current information.

Services
Custom-home design and construction
For homeowners planning an individual residence. The official portfolio includes waterfront houses and featured homes in traditional, coastal and contemporary forms. The published examples provide a starting point for discussing the site, layout and architectural approach.
Residential additions
For owners who want to extend an existing home. The company’s addition gallery and stated in-house design and framing capability are relevant to creating new space that connects with the existing structure.
Home renovations
For substantial changes to an existing property. The renovation portfolio shows reworked homes, including Traditional Revisited and Island View, rather than a menu of standard refurbishment packages.
Design images and pre-construction visualisation
The CAD galleries communicate proposed building form, while CAD to Finished Home comparisons show selected designs beside completed photographs. Ask the company which drawings and visualisations are included in a proposed commission.
