From rebar installation to moisture protection and utility placement, every detail needs to be checked before moving forward. Getting this stage right helps create a strong foundation for everything built above it.

The right choice depends on your goals, space, and long-term plans.

Thinking about expanding your home but not sure which direction makes more sense?

An ADU and a room addition can both add value โ€” but they serve very different purposes.

An ADU works best if you want:
โœ” Rental income
โœ” Guest space
โœ” A separate living unit

A room addition may make more sense if you need:
โœ” More living space
โœ” Extra bedrooms
โœ” A seamless extension of your current home

The right choice depends on your goals, property layout, budget, and long-term plans.

Hereโ€™s a quick breakdown to help simplify the decision.

Save this for future planning and follow for more homeowner construction insights.

A closer look at the utility work powering future development.

A lot of the most important work on a construction site happens below the surface.

Hereโ€™s a closer look at the manhole and utility installation work currently taking place at Montecito Drive as progress continues on-site.

Infrastructure and utility planning play a critical role in every development project โ€” helping support drainage, access, and long-term functionality from the ground up.

At ATP, we believe strong projects start with strong foundations, careful planning, and attention to every detail behind the scenes.

Follow along for more construction updates and behind-the-build progress from the field.

Some rooms just feel different.

The NHCA-LA Mixer brought together builders, leaders, and problem-solvers who are shaping what Los Angeles looks like โ€” one project at a time.

Grateful to be in the room. See you at the next one.

The NHCA-LA Mixer brought together some of the best in the industry โ€” and we were glad to be part of it.

Events like this are why community matters in construction. Real conversations, real connections, and a reminder that the work we do in Los Angeles is bigger than any single project.

Thanks to for having us. Already looking forward to the next one.

Framing complete.

This is one of our active Altadena projects on Saint James Place. Weโ€™re past the frame and now working through rough utilities: electrical, plumbing, HVAC rough-in.

This stage is where a build gets its nervous system. Everything thatโ€™s hidden behind your walls starts here.

ATP handles architecture, structural engineering, permitting, and construction under one roof. This is what that looks like in the field.

Altadena is being rebuilt. We're proud to be part of it.

This Modern Contemporary single-story is currently under construction in Altadena โ€” 1,648 sq ft, 3 bed / 3 bath. Designed from the ground up for the family coming home.

Every one of our Altadena projects is built with the same level of care: tight timelines, clean work, and full transparency with the homeowner every step of the way.

DM us if you want to tour any of our active rebuild sites.
