Home extensions: What every family needs to know

Does this sound familiar? Your home office has taken over the dining room, the children need more space to play, and you’re constantly tripping over each other.

You’re not alone – many families are feeling the squeeze and wondering whether it’s time to expand.

But here’s the big question: should you go for a traditional brick extension or opt for one of those trendy modern sunrooms?

What will it actually cost you?

Let’s be honest about budgets. According to Claude McKirby from Lew Geffen Sotheby’s International Realty in the southern suburbs, home extensions are smart investments — if you do them right.

“It’s all about balancing what you need now with what makes financial sense long-term,” says McKirby.

Sunrooms: the quick and affordable option

Remember those old-school conservatories that were freezing in winter and boiling in summer? Today’s sunrooms are nothing like that. They’re properly insulated, designed for our climate, and won’t leave you sweating or shivering.

The numbers? You’re looking at anywhere from R80 000 for a basic small sunroom up to R350 000 for a decent medium-sized one. Want all the bells and whistles — automated louvers, solid roofs, the works? That could push you towards R800 000.

The best part? Once you’ve sorted out municipal approvals (if you need them), your new room could be ready in just three to eight weeks.

“Most sunrooms come as kits that are put together on-site, so there’s way less mess and disruption for your family,” McKirby explains.

Brick extensions: the traditional route

Want a room that looks like it’s always been part of your house? Brick is still king for bedrooms, home theatres, or kitchen expansions.

But it comes with a bigger price tag. Basic single-storey extensions start around R250 000, with most projects falling between R400 000 and R800 000. Go fancy with high-end finishes or complex structural work, and you could easily hit R1,2 million or more.

Time-wise, you’re looking at minimum three months from start to finish — often longer. And yes, there will be noise, dust, and general chaos.

“It’s definitely more invasive, so you need patience,” warns McKirby.

Which option gives you the best bang for your buck?

Right now, McKirby reckons sunrooms are winning the investment game.

“South Africans love that indoor-outdoor lifestyle, and a well-done sunroom really captures that. For a family room that brings in lots of light and connects you to your garden, it’s often the smart choice.”

But if you absolutely need a room that seamlessly blends with your existing house — think matching bricks, integrated design — then traditional brick building is your only option.

Making your new space work for everyone

Whatever you choose, how you design the interior will make or break the space. Nobody wants another room that just collects clutter.

Smart design tips:

• Zone it right: Use rugs and furniture to create different areas — lounging here, dining there, maybe a work corner.
• Storage is everything: Built-ins, storage ottomans, banquette seating with hidden storage — anything to keep the mess under control.
• Keep it comfortable: For sunrooms especially, invest in proper blinds and make sure you’ve got enough ventilation.

The bottom line

“A good extension improves your family’s daily life while adding real value to your property,” says McKirby. “Take time to think through your options and design something flexible that works now and will still make sense if you sell down the line.”
