House extensions and home additions in Cape Town
Extending your home is a major project that needs careful planning, realistic budgeting, proper coordination and the right professional input from the start.
BOMO Renovations helps Cape Town homeowners plan and manage house extensions, room additions, second-storey extensions and related renovation work with clear communication, practical design guidance and careful coordination of the relevant trades.
Whether you are adding a bedroom, expanding a living area, creating a home office or improving the connection between your home and outdoor space, we help bring structure to the process from early scope review through to renovation and handover.
Planning a house extension in Cape Town
A house extension is not only about adding extra space. It can affect the layout, structure, roofline, foundations, drainage, natural light, access, finishes and municipal approval requirements.
Before starting, it is important to understand:
- What space you want to add
- How the extension will connect to the existing home
- Whether structural work is required
- Whether building plans or approvals may be needed
- How the extension will affect light, ventilation and flow
- What level of finish is expected
- What budget range is realistic for the project
House extension and addition services
BOMO can assist with different types of house extensions and related renovation work, depending on the property, scope and approval requirements.
Room additions
Additional bedrooms, home offices, guest rooms, living areas or utility spaces designed to work with the existing layout of the home.
Living area extensions
Extensions that improve kitchens, dining areas, lounges or indoor-outdoor flow, especially where the existing home feels too small or disconnected.
Second-storey extensions
Where suitable, second-storey additions can create extra living space without using more outdoor area. These projects usually require careful structural input, planning and approval.
Outdoor-connected extensions
Extensions linked to patios, courtyards, braai areas, pool areas or garden spaces, helping the home connect better to outdoor living.
Structural and finishing coordination
House extensions may involve demolition, foundations, structural work, roofing, windows, doors, flooring, painting, electrical, plumbing and finishing details. BOMO can help coordinate the broader renovation scope.
Building plans and professional input
Many house extensions require architects, engineers or municipal approvals. BOMO can help identify where additional professional input may be required and coordinate with the relevant professionals where needed.
Our house extension process
Every house extension starts with understanding the property, the intended use of the new space and the likely approval or professional requirements.
1
Send project details
Send us photos, videos, measurements where available, the property location, current layout and any reference images or ideas for the extension.
2
Scope review & design guidance
We review the information and may follow up with questions about layout, structure, access, approvals, finishes, budget range and timeline.
3
Professional input and estimate
Depending on the scope, a house extension may require input from an architect, architectural technologist, structural engineer or other professional. Where possible, we prepare an estimated quotation so you can understand the likely cost before arranging a site visit.
4
Site visit and final quote
If the estimate is aligned with your expectations, we visit the property, confirm practical details and refine the quotation.
5
Coordination & renovation
Once approved, and once the required plans or permissions are in place where needed, BOMO coordinates the relevant trades, suppliers, site work and communication throughout the renovation.
6
Finishing & handover
We review the final details, manage snagging where needed and hand over the completed work as cleanly and professionally as possible.

I couldn’t be happier with the work Clara did on my apartment! From start to finish, she was professional, attentive, and incredibly creative. She took the time to understand my vision and then elevated it with her own design expertise, turning my space into something far more beautiful and functional than I imagined. What impressed me most was her attention to detail—every finish, every corner, every choice felt intentional and perfectly executed. Clara managed the project seamlessly, keeping me updated throughout and making the whole process stress-free. Now, my apartment feels brighter, more spacious, and truly like home. Friends and family can’t stop complimenting the transformation, and I owe it all to Clara’s talent and dedication. If you’re considering a renovation, I wholeheartedly recommend Clara. She doesn’t just remodel spaces—she reimagines them with style, warmth, and precision.Posted on Google CS A2025-07-30Trustindex verifies that the original source of the review is Google.
