Home Additions 

Need that Extra Room 
For most homeowners a day comes that their family outgrows their current interior space. The debate of moving or adding additional square footage to their existing home structure  starts to be an evening diner discussion. Most homeowners think that a room addition involve too much red tape or simply is too expensive to built.
​

Adding additional square footage to your home is more cost effective than buying a new home especially with the current  rising home market prices, and bidding wars, which is the current landscape for much of Southern California housing market. CentrePoint's years of experience in home additions ensure that our streamlined process of building an addition will be as smooth as possible from consultation, blueprints, obtaining  city permits, and construction. CentrePoint Construction is  focused and committed to delivering the best customer service and workmanship for  that kitchen extension, new home office space or master bedroom. 

​

The process of a home addition from A to Z:

 

Planning and design process

During our initial meeting the design-build team and client will meet to get a clear understanding of what the owner wants to achieve in the project’s scope and budget guidelines. The team will also conduct site evaluations and feasibility studies. A detailed plan for your home additions keeping within your budget. Your plans will include floor plan, elevations, engineering specification, Low Impact Development (LID) and Title 24. Once your plans are ready to issue and permits are pulled we will mobilize to start your project.

​

Breaking ground on your project

Before we start digging for the new foundation for safe excavation, we will obtain all utility clearance from 811 DigAlert. Once we have an approval and marketing of all utilities, we are ready to clear the site and remove any obstruction that could affect the foundation's stability. The site may need to be graded or leveled to ensure proper drainage. The area for the foundation will be excavated, rebars will be placed, dowelling will be installed to connect existing to new foundation, are a few of the steps before pouring concrete. Finally, the foundation will be inspected by deputy inspector, engineer and city inspector to ensure that it meets all building codes and regulations. Once approved we proceed to pour concrete.

​

Framing your home addition

We start with lay out the sill plate made out of treated wood, secured to the top of the foundation wall using bolts and hold-down rods that were already placed during foundation. This is essentially the base of the home's framework. Referring to the framing plans we start to build the house. Rim joists, floor joist and first-floor 2x4 or 2x6 walls with post are built using high grade lumber yard wood. Once we’re ready we install structural beam composite lumber like LVL, PSL, Glulam or steel I-beam just depends what the engineer calls for. It’s time to put the roof structure on with either pre-manufactured trusses or built-up rafters, depending on the design. Once we have the walls and roof up, we start with installing plywood sheathing for the roof and shear walling the walls. The shear walls are structural support element that resists racking shear forces, from heavy winds and seismic activity. Hardware installation like CMST12 straps, Simpson strong tie Hold-Down and other engineered specified hardware will be installed. will be inspected by deputy inspector, engineer and city inspector to ensure that framing meets all building codes and regulations. Once approved we proceed to drywall, exterior application and installing all finishes.

​

Installing HVAC, plumbing and electrical systems

While foundation and framing are being constructed, in parallel to those stages in the construction, is the essential services to a building, which are mechanical (HVAC), Electrical, and Plumbing. All three systems are known as the (MEP). The MEP is planned during the design phase. The Engineers work with Architects to ensure that these systems integrate into the dwelling design. Once we breakground on the project all three trades work together with our team to provide a seamless process to make sure everything is installed according to approved plans. The city inspector will be called at different stages of MEP installing leading ensuring that  all building codes and regulations are met.
