Farmhouse 2-Bedroom ADU
Farmhouse ADU Plan: 722 SF, 2-Bed / 1-Bath
This 722 square-foot plan spans a 20×40 footprint on a single story. The open kitchen, dining, and living area opens from the entry with a wood stove anchoring the main living space — the kitchen includes built-in ovens and is designed for real daily use. Two bedrooms and a full bathroom with frosted-glass shower sit toward the rear, with a dedicated laundry room off the hall. The uncovered rear deck on a concrete base adds meaningful outdoor space. Structurally, the unit uses reinforced concrete C40 foundation with pre-routed sewage, 15x5cm wall studs, 15x15cm structural poles, and rockwool insulation throughout. Underfloor heating runs on an electrical heat pump embedded in lightweight concrete — no gas line required. Well suited for multigenerational households, long-term rentals, or as a fully independent primary residence.

Permit-Ready Plans and Construction Details
This design is drawn to permit-ready standards. The reinforced concrete C40 foundation pad (35–40cm) includes pre-routed sewage pipes and a 10–15cm lightweight concrete pour for electrical, water, and underfloor heating systems. The 15-degree pitched roof uses OSB3 sheathing, insulation board, and a choice of asphalt tiles or 5cm metallic sandwich panel with 7.5cm polyurethane — solar panels are integrated into the roof plan. The exterior finish choices are a 5cm metallic sandwich panel with polyurethane or horizontal wood planking with paint; interior walls use OSB, 12mm plasterboard, plaster, and paint over rockwool insulation. MolaADU prepares and submits all permitting documentation on your behalf.

Is This Plan Right for You?
Our curated ADU plans offer several advantages:
• Faster Permitting: These plans are designed to meet local codes, helping reduce approval times.
• Lower cost: Skip custom design fees with professionally designed layouts tailored to local requirements.
• Simplified Process: These plans eliminate much of the uncertainty in the design and permitting stages.
They are a great option for homeowners who want to fast-track the design & permitting process and reduce costs. However, it is important to note that these plans cannot be customized. They are fixed designs intended to simplify and expedite the process, but they do not allow for adjustments such as reconfiguring rooms, resizing, or adding custom features.
If you’re looking for more flexibility, SnapADU offers a variety of semi-custom ADU plans. These designs can be tailored to your property and lifestyle, allowing for adjustments to size, layout, and finishes while still offering the efficiency of a pre-designed structure.
