Room addition and home expansion by Loughman Builders and Remodelers in Belleville Illinois

More Space Without Starting Over Somewhere Else

As families grow and needs change, a home that once had plenty of room can begin to feel tight. A room addition gives you the opportunity to expand the house you already know without giving up the neighborhood, property, or location you already enjoy.

Loughman Builders & Remodelers plans additions around the existing home so the new space feels connected both inside and out. From a single-room expansion to a larger living suite, the goal is to create useful square footage that belongs with the original structure.

01 / EXPAND

Add Needed Space

Create additional bedrooms, bathrooms, living areas, offices, guest quarters, or other rooms without moving to a different home.

02 / CONNECT

Blend New With Existing

Roofing, siding, windows, trim, proportions, and interior finishes are planned so the addition works with the existing home.

03 / ADAPT

Plan for Changing Needs

Additions can give growing families, guests, relatives, remote workers, and changing households more usable space.

Types of Room Additions We Build

Every addition begins with the home that is already there. Available space, property layout, existing structure, access, and how the new room will be used all affect the design.

Whether you need one additional room or a larger multi-room expansion, the project is planned around your home and household needs.

✓ Sunrooms and four-season rooms
✓ Additional bedrooms
✓ New bathrooms
✓ Primary suite expansions
✓ Living room extensions
✓ Home offices and studios
✓ In-law suites and guest quarters

A Room Addition Is More Than Four New Walls

A successful addition has to connect structurally and visually with the existing house. Foundation, framing, roofing, insulation, electrical, plumbing, windows, siding, drywall, trim, and interior finishes all have to work together.

● Foundation & Structure
Build the new addition around the structural requirements of the home and project.
● Framing & Exterior Walls
Create the new structure and connect it properly to the existing building.
● Roofing & Siding
Coordinate exterior materials and roof lines so the new space looks connected to the home.
● Windows & Doors
Plan openings around natural light, access, exterior appearance, and the function of the new room.
● Electrical & Plumbing
Extend the systems needed for lighting, outlets, bathrooms, kitchenettes, and other features where included.
● Interior Finishing
Complete the addition with insulation, drywall, flooring, trim, doors, and finish details.

ONE HOME • NOT TWO BUILDINGS

The Addition Should Look Like It Belongs There

The best additions do not look like a separate box attached years later. Exterior proportions, roof lines, siding, trim, windows, and interior transitions all affect whether the new space feels natural.

We plan the connection between old and new construction carefully so the addition works with the existing house instead of fighting against it.

Build the Addition Around What the Space Needs to Do

The purpose of the addition should guide the layout. A guest suite has different needs than a sunroom. A primary suite has different plumbing and privacy requirements than a home office or living room expansion.

Growing Families
Bedrooms, bathrooms, and additional shared living space
Guest Space
Comfortable accommodations for visiting family and friends
Multigenerational Living
More privacy and flexibility for relatives sharing the home
Work & Hobbies
Dedicated office, studio, or creative space

Additions Can Include Bathrooms and Kitchenettes

Guest quarters, primary suites, and larger living additions may include a new bathroom or kitchenette as part of the project. Plumbing, electrical service, ventilation, storage, and room layout all need to be considered during planning.

Add Space Where You Already Live

A room addition can make sense when the home still works for your household but simply does not have enough space. It allows you to adapt the property to changing needs without automatically giving up the location, yard, neighborhood, or parts of the home you already like.

The added space can also make the home more useful over the long term, whether the goal is a larger family area, a private suite, a dedicated workspace, or room for guests.

Experience Matters When You Are Changing the Structure of Your Home

Room additions involve more than interior finish work. The new structure has to connect with the existing foundation, framing, roof, exterior, utilities, and living space.

Room Addition FAQs

How long does a room addition project take?

Room addition timelines vary based on size, design, structural work, permits, inspections, utilities, and finishes. We establish the expected project schedule during planning.

Will the addition match the existing home?

Matching the existing home is an important part of the planning process. Roofing, siding, windows, trim, proportions, and interior finishes are considered so the addition blends as naturally as practical.

Do you build in-law suites or guest quarters?

Yes. Depending on the home and project, additions can include private living space, bathrooms, kitchenettes, bedrooms, and separate-entry layouts.

Can a room addition include a new bathroom?

Yes. Bathrooms can be incorporated into bedroom suites, guest quarters, and other additions when the layout and plumbing requirements support the design.

Do you handle permits and inspections?

Yes. Required permits, code requirements, and inspections are handled as part of the room addition project.

Can you remodel the existing rooms where the addition connects?

Yes. When needed, the project can include remodeling or reconfiguring existing interior areas so the old and new spaces work together.
