Key Works to Unlock the Potential of Your Garage

For a successful garage conversion project, DevArt8 Construction takes care of the key elements that will transform this underutilized space into a functional and inviting part of your living area.


Garage Door Infilling

The process involves removing the garage door mechanism and filling the opening with brickwork or appropriate construction materials. This step is essential for structural integrity and aesthetics, seamlessly integrating the new living space with the rest of the house.


Floor Slab Levelling

If the existing garage floor is uneven, it may need leveling to ensure a smooth and stable surface. This will involve using a self-leveling compound or screed to create a flat base for further work.


Damp-Proofing the Floor

Inspecting the garage floor for moisture issues, addressing any cracks or gaps, and applying a high-quality damp-proof membrane to prevent moisture from seeping into the new living space. This is crucial to maintain a dry and comfortable environment.


Floor and Wall Insulation

Insulating the floor and walls to maintain a comfortable interior temperature. Depending on the type of flooring and walls (single-skin or cavity), we use suitable insulation materials to meet building regulations and maximize energy efficiency.


Windows and Doors

Choose high-quality windows and doors that complement the design and functionality of the converted space. Installing double-glazed windows helps with insulation and soundproofing, ensuring a comfortable and quiet environment.


First-Fix Services

This involves installing electrical wiring, plumbing, and joinery work. It involves planning the layout carefully ensuring adequate power outlets, lighting points, and plumbing connections for the intended use of the space.


Plasterboarding and Plastering

Applying plasterboard to the walls and ceilings, providing a smooth and even surface for paint or wallpaper. Plaster over the boards to create a polished finish, paying attention to corners and joints for a seamless look.


Finishing Touches

Installing new internal doors that match the overall aesthetic of the converted space. Adding moldings like skirting boards and architraves for a polished appearance. Choosing the final floor covering, whether it’s hardwood, laminate, tile, or carpet, and install the selected lighting fixtures for both functionality and ambiance.

Different Types of Garage Conversion Projects

Whether your garage is attached, integrated, or detached, we've got you covered. Here's a breakdown of the different types of garage conversion in Bay Area:

Types Of Garage Conversion
  • Full Integral Single Garage Conversion: This is the most common and cost-effective option. An integral garage is seamlessly attached to your property within the main walls. Access is typically via an area of your home, often leading to a utility room or through the kitchen.
  • Partial Garage Conversion: A partial conversion is ideal if you’re looking to balance the need for living space with garage storage and budget constraints. Typically, the rear portion of your existing garage becomes the new living area, allowing you to maintain front space for traditional garage use. A partition wall divides these areas.
  • Double Garage Conversion: Need more room? A double garage conversion is as straightforward as it sounds – you will double your available space. Many homeowners allocate half the area for parking and storage while converting the other half for living space.
  • Detached Garage Conversion: If your garage is separate from your main property, you’re looking at a detached garage conversion. This option involves more planning, including garage insulation, and may require planning permission. While it can be more costly, the results can be exceptional. Additionally, if it’s close enough to your house, you might consider adding an integrated passageway for convenient access.

No matter the type of garage conversion you’re considering, we’re here to guide you through the process and bring your vision to life.

Garage Conversion Regulations and Permits in Bay Area

Whether your garage is attached, integrated, or detached, we’ve got you covered. Here’s a breakdown of the different types of garage conversion in Bay Area:

A Converted Kitchen Space
  • Fire Safety: Ensure proper escape routes and fireproofing measures are in place.
  • Ventilation: Implement moisture-proofing and efficient ventilation systems for safety and comfort.
  • Thermal Performance: Insulate the floor, walls, and loft to meet energy efficiency standards.
  • Acoustics: Incorporate soundproofing to maintain a peaceful environment.
  • Electrics: Entrust electrical work to a qualified electrician to meet safety standards.
  • Structural Concerns: Assess and reinforce beams, columns, foundations and other structural members as needed for structural integrity.
  • Slab-on-Grade Caution: Before any saw cutting or breaking of a slab-on-grade, it’s essential to determine if it’s a post-tension slab. Cutting a tendon in these slabs can be hazardous and costly to repair.
  • Homeowners Association (HOA): If your property falls under the jurisdiction of a Homeowners Association, exterior work, including garage conversions, requires approval from the Association. It’s the responsibility of the property owner to obtain this approval.
  • Architectural Plans: Following architectural plan requirements is crucial, including: Site (Plot) Plan: Display existing buildings, structures, property lines, and nearby streets or alleys.Indicate distances between existing garage walls and property lines. Show the true North direction.Highlight existing and proposed parking spaces. Note that planning regulations typically mandate specific off-street parking requirements based on the number of bedrooms.
  • Floor Plan: The Floor Plan should outline the existing rooms within the house and the new rooms resulting from the garage conversion. Clearly label the intended use of each room and provide comprehensive information to describe the scope and approach of the work.
