1. Single-Storey Extensions
A single-storey extension adds light, space and value. It works well for open-plan kitchens and dining rooms. Many Oldbury homes are terraced or semi-detached, so this is a popular choice.
2. Double-Storey Extensions
Need more room upstairs and down? A double-storey extension gives you a bigger living area and extra bedrooms. It can also add a bathroom or study.
3. Rear Extensions
A rear extension opens up your home to the garden. It’s ideal for a larger kitchen or a relaxed family lounge.
4. Side Return Extensions
Got a narrow, unused side passage? A side return extension turns it into useful floor space. It’s a smart fix for terraced homes.
5. Wraparound Extensions
This joins a side and rear extension into one large space. It reshapes your whole ground floor. It suits busy families who want a modern layout.
6. Kitchen Extensions
A kitchen extension gives you room to cook, eat and spend time together. It’s one of the best ways to improve your home without moving.
7. Open-Plan Kitchen and Living Extensions
Remove the walls between rooms and let the light flow. Open-plan living is great for hosting friends and keeping an eye on the children.
8. Utility and Boot Room Extensions
Tired of muddy shoes in the hallway? A utility or boot room keeps clutter out of sight. It also gives you space for laundry and storage.
9. Additional Bedroom Extensions
Growing family or regular guests? An extra bedroom gives everyone breathing space. It also adds long-term value to your property.
10. Home Office Extensions
Working from home is easier with a proper office. A separate extension keeps work quiet and apart from family life.
Not always. Some extensions fall under permitted development rights. Others need approval from Sandwell Council. It depends on your property, the size of the build and any past changes. We help you confirm the right route.
In most cases, yes. These rules cover safety and performance. That includes structure, insulation, ventilation, drainage and fire safety.
Often, yes. If you’re removing a wall or adding steel beams, an engineer will usually be needed. We can coordinate this for you.
Yes. Kitchen and open-plan living spaces are some of our most requested projects. We design the layout around how you cook, eat and relax.
It depends on size and complexity. A small single-storey build is quicker than a double-storey one. We’ll give you a realistic timeline after your site visit.
A smart extension can give you a bigger kitchen, an extra bedroom or a brighter family room. No need to move.
