Room Additions

Home additions designed around the way you live

A room addition expands the existing home and connects new space to its floor plan. The goal might be another bedroom, a larger family room or a dedicated office that does not take over the dining table.

A successful plan considers the rooms you already have. A new room needs a useful entrance, sensible circulation and a connection to the house that works from both inside and outside.

Room addition ideas for your Sacramento home

Bright bedroom with clay bedding and garden-facing windows.

Bedroom and primary suite additions

Think through privacy, storage and the relationship to nearby rooms. A suite with a bathroom introduces different plumbing and layout decisions from a bedroom alone.

Family room and home office additions

Separate quiet work from shared activities, or create a larger gathering space. Plan doors, daylight and furniture before deciding that more square footage alone solves the problem.

Kitchen and custom home expansions

An addition can make room for an enlarged kitchen or bathroom. Coordinate the new footprint with the existing layout and the systems serving those rooms.

Designed for everyday living

Home additions that connect with your existing space

An addition can let you remain in the neighborhood you enjoy while changing how the house works. Its value to daily life comes from the layout and use, not simply the size.

Roof connections, exterior finishes and changes to existing rooms can be substantial parts of the project. A design that looks simple from the yard may still involve work inside the house.

Planning your project

Planning your design-build room addition

Describe the problem you want to solve and how you expect to use the room. Photos and an existing floor plan, if available, help explain circulation and possible access points.

Petkus Brothers' design-build capabilities include planning, engineering, permitting and construction. Confirm the responsibilities, existing-condition allowances and included finishes for your proposal. Site constraints and the applicable local review process need to be considered before a schedule is established.

About Petkus Brothers

Find the right fit

Room addition, sunroom or ADU?

Choose the project around the space you need and how it should relate to your existing home.

Expand the existing home

Room additions create more space for daily activities, from gathering to working or sleeping.

Prioritize daylight and views

A sunroom emphasizes a glass-enclosed connection to the outdoors. It is not automatically equivalent to a conventional addition.

Sunrooms

Consider additional living space

An ADU can provide residential living space for family, guests and changing household needs.

Common questions

Room Additions Questions

Should I add a room or remodel the space I already have?

If the existing footprint is sufficient but the layout is awkward, remodeling may address the problem. An addition becomes worth discussing when the home needs more usable space. Start by describing what is missing from your current layout.

Can an addition include a bedroom and bathroom?

Petkus Brothers offers bedroom, primary-suite and bathroom additions. The layout, connections and existing systems need project-specific review before the scope can be confirmed.

What is included in a design-build addition?

The design-build approach coordinates planning and construction. Review your proposal for the actual design, engineering, permit, construction and finish responsibilities rather than assuming every service is included at the same stage.

What makes one room addition cost more than another?

Room size is only one factor. Foundations, roof connections, plumbing, electrical work, finishes and alterations to the existing home can all change the scope and estimate.

Can we stay in the house during an addition?

That depends on how construction connects to the occupied rooms and whether essential spaces remain usable. Discuss access, dust separation, utility interruptions and any temporary living arrangements before work begins.
