Overview
I am converting an existing shed + open carport into a hobby room.
The existing structure consists of:
- an insulated shed,
- an attached open carport,
- an existing brick wall connected to the house,
- and an existing door to the garden.
The goal is to:
- fully enclose the current carport area,
- create a insulated indoor space,
- and make the space weatherproof and suitable for all-season use.
I will complete some interior work myself (insulation, finishes, etc.), but I would like professionals to complete the exterior shell and openings.

Requested Professional Scope
1. Construct New East Exterior Facade with Window and Door
Build and fully weatherproof a new exterior east facade where the current carport opening exists. Install window and door to the facade. I plan to install interior insulation and interior finishes myself afterward.
The facade should include:
- structural framing (which fits the door and window)
- weatherproof layer,
- ventilated rainscreen if suitable,
- installation-ready cavity for future insulation by owner,
- install the window and door (I will purchase the window and door myself).
2. Replace Door to Yard
Take down the exisitng door to the yard, and install a new door (I will purchase the door myself).
Requirements:
- weatherproof installation,
- airtight sealing,
- proper flashing and threshold detailing,
- suitable for year-round heated use.
Position approximately as shown in attached drawings/sketches.
3. Add New South-Facing Window in Existing Shed Wall
The current south-facing shed wall is already insulated. I need a window to be added to the wall for better lighting.
Requirements:
- cut and frame new opening correctly,
- install window (I will purchase the window myself),
- proper flashing/weatherproofing,
- maintain structural integrity and weather protection,
- suitable for heated studio use.
DIY Work by Owner
I plan to complete some work myself after the shell/openings are completed, including:
- insulation,
- interior wall finishes,
- some floor finishing.
Therefore I would like the contractor scope focused primarily on:
- framing,
- exterior envelope,
- openings,
- weatherproofing,
- structural work,
- window/door installation.
Request
Please kindly provide:
- any concerns to the idea mentioned above,
- approximate timeline,
- and quotation estimate.
I made a rough floorplan showing the existing structure and intended layout. Photos of the existing structure is also included for your reference.
