More Space, More Possibilities

Your home should have enough room for the people and activities that matter most. Whether you need another bedroom, a larger living area, or a separate space for family, Double P General Corporation helps you explore construction options that fit your property and plans.

Bedroom & Room Additions

Need an extra bedroom or more room for everyday living? A home addition can provide the space your household needs while keeping everything under one roof. We build additions that work with your existing home.

Home Bump-Outs & Expansions

Sometimes a little extra room makes a big difference. A bump-out can extend part of your home to create more usable space in a kitchen, living room, or other area without adding an entirely separate room.

Backyard ADU Construction

Create a separate living space on your property with a backyard accessory dwelling unit (ADU). These smaller homes can offer privacy and independence for family members or guests while keeping everyone close.

Garage Suites

Make better use of your property with a garage conversion designed for additional living space. Whether you're planning accommodations for family or guests, we'll help you explore a layout that fits your goals and property.
WHY BUILD AN ADDITION OR ADU?

Keep Your Address, Expand Your Space

Your needs may change, but that doesn't mean you have to leave the home you love. Building an addition or ADU can give you more options for everyday living, family arrangements, and the years ahead.

Stay Where You Love Living

You shouldn't have to give up your neighborhood just because your house feels too small. Adding space can help you stay in the home you know while making room for the things your family needs.

Give Everyone More Room

Shared rooms and crowded living areas can make everyday life frustrating. Additional space can mean a private bedroom, a larger gathering area, or simply more room for everyone to feel comfortable.

Keep Family Close, With Room to Breathe

A separate living space can help aging parents or adult family members stay nearby while enjoying more independence. An ADU offers another way to support changing family needs without sharing every room.

Spend Less Than You Would Moving

Buying a larger home often comes with selling fees, moving expenses, and a new mortgage. Depending on your project, expanding your current home likely costs less than moving to a bigger property.
PLANNING YOUR NEW SPACE

A Clear Path From Idea to Addition

Adding living space is a major decision, and every property comes with different possibilities. We'll help you understand your options, think through the important details, and prepare for the work involved.

1. Tell Us What You Need

We'll start by discussing why you need more space and how you plan to use it. Whether you're considering an extra bedroom, a larger living area, or a separate ADU, we'll listen to your goals and review your property.

2. Explore What's Possible

We'll look at the available space, your existing home, and the type of construction you're considering. We'll also discuss your budget and any local requirements that could affect the project, including permits and utility connections.

3. Plan the Construction

Once we've established the direction of your project, we'll review the layout, materials, expected schedule, and construction details. We'll also discuss how necessary approvals will be handled before the work begins.

4. Build Your New Space

With the preparations complete, construction can begin. Our team works through the planned building stages and finishing details, keeping you informed along the way. We'll review the completed work with you before wrapping up.
