30x46 Modern Cottage House Plan with Loft, 3 Bed, 2 Bath, 1,800 Sq Ft

This 30x46 modern cottage floor plan delivers 1,800 sq ft of heated living space across a main level and a full loft second floor, combining an open-concept layout with a cabin-style exterior that works equally well as a full-time residence or a getaway build. The design pairs a spacious central living and dining area with three bedrooms and two full baths plus a powder room, giving a growing household or group of guests real separation without sacrificing the open feel on the main floor.

On the ground level, the layout opens into a 189 sq ft living room and 113 sq ft dining area anchored by an 88 sq ft kitchen, with a private main-level bedroom at 163 sq ft and a full 68 sq ft bathroom just off the hall, along with a 21 sq ft powder room for guests. A 65 sq ft foyer and 9 sq ft laundry nook keep the entry and utility functions tucked out of the main living space. Upstairs, the loft holds two additional bedrooms at 156 sq ft each, a shared 72 sq ft bath, a 111 sq ft loft foyer, and four dedicated storage rooms, so the upper level functions as a real second floor rather than an open sleeping loft. Covered porches front and back, each 240 sq ft, extend the living space outdoors.

Structurally, the home sits on a pier and footing foundation, well suited to sloped or uneven lots, with wood stud wall framing and 2x6 roof rafter construction under a gable roofline. The drawing set specifies insulated exterior walls and energy-efficient windows throughout, along with durable roofing materials built to handle a range of climates. Framing and connection details follow the 2022 California Residential Code (IRC 2021 with amendments), with wind loads calculated to ASCE 7-16.

This plan fits owner-builders who want a proper multi-bedroom cottage rather than a single-story cabin, as well as buyers looking for a vacation home, a rental property, or a year-round residence with room for family or guests. The two-story layout also suits anyone wanting bedrooms separated from the main living area for privacy and noise control.

As with all our plans, this design is not engineer-stamped or pre-approved for any specific jurisdiction. Local building departments vary in what they require, and many areas call for a licensed architect or engineer to review and seal the plans before a permit is issued. We recommend checking with your local building department before purchasing to confirm what's needed in your area.
