Selling a house, gutting a kitchen, or combining two households before the holidays all lead to the same search: self storage near me, big enough for most of a home. Alliance Storage, at 18104 Sylvester Ford Rd in Lago Vista next to Jonestown, rents two large unit sizes, the 10x15 and the 10x20, with a climate-controlled option on the 10x15. This guide covers what each large unit holds, what it costs per month, how to choose between them, and how access works.

Large storage units in Lago Vista: sizes and prices

Alliance Storage publishes its rates online. Standard monthly rates for the large units:

  • 10x15 non-climate: $145 per month
  • 10x15 climate-controlled: $185 per month
  • 10x20 non-climate: $180 per month

Every standard unit at Alliance Storage has an 8-foot interior height. That gives a 10x15 about 150 square feet of floor space and about 1,200 cubic feet in total, and a 10x20 about 200 square feet and about 1,600 cubic feet.

Units are reserved online with a $10 reservation deposit that is credited to the first invoice. Current availability for each size, including any waiting list, is on the rent storage page.

What fits in a 10x15 storage unit

A 10x15 holds the contents of about three bedrooms, plus the larger pieces that do not fit in smaller units:

  • Three beds with their dressers and nightstands
  • A sofa or sectional, armchairs, and a coffee table
  • A dining table and chairs
  • Large items such as a piano or a large-screen TV
  • Several medium and large boxes

It is the usual choice for a household that is between homes, or for clearing most of a house before it goes on the market.

What fits in a 10x20 storage unit

A 10x20 is the largest standard unit at Alliance Storage. It holds the contents of a multi-bedroom house, including oversized items:

  • Bedroom, living room, and dining room furniture together
  • A refrigerator and a washer and dryer
  • Couches, a dining set, and large boxes
  • Patio furniture, tools, and yard equipment on top of the household contents

It suits a full-house move, a long remodel where several rooms are emptied at once, or two households combining into one.

10x15 or 10x20: how to choose

The 10x20 has a third more floor space than the 10x15 and costs $35 more per month as a non-climate unit. A few questions settle the choice:

  • Are appliances going in? A refrigerator, washer, and dryer together take up a lot of floor space. With appliances plus a full house of furniture, the 10x20 is the safer size.
  • How many rooms are being emptied? Three bedrooms and a living room usually fit a 10x15. A whole house with a garage usually needs a 10x20.
  • Does anything need climate control? The 10x15 is the only large size offered as climate-controlled at Alliance Storage.

Climate-controlled or non-climate in a large unit

A 10x15 climate-controlled unit is $185 per month and a 10x15 non-climate unit is $145 per month, a difference of $40. The climate-controlled 10x15 is the better fit when the unit holds wood furniture, mattresses, electronics, a piano, or boxes of photos and documents, and especially when the stay will run several months.

A non-climate 10x15 or 10x20 works well for appliances, outdoor furniture, tools, and items packed in sealed plastic bins, and for shorter stays around a closing date or a remodel. The post on climate-controlled storage in Lago Vista goes into the climate-controlled sizes in more detail.
