What Affects the Price?

The final price of your kitchen extension may vary depending on a number of factors. You may make wise selections and manage your spending by being aware of these.

Complexity of Design

Compared to a wraparound or side-return extension, a basic rear extension will be less expensive. The cost will increase if your plan calls for structural modifications, such as eliminating load-bearing walls or adding bi-fold doors.

Materials Used

Basic materials are inexpensive, but high-end finishes like custom cabinets, granite countertops, or opulent tiling will cost more.

Permissions and Planning

There can be extra costs if your House extension needs planning approval. Kitchen additions often come under allowed development, but you should always check with your local government or let our staff take care of it for you.

Employees and Contractors

Selecting a skilled group such as Denham Crescent Ltd. guarantees high-quality work. Even if you could discover quotations that are less expensive, hiring qualified experts helps you avoid costly errors down the road.

Appliances and Utilities

The cost is increased by installing appliances, lights, gas lines, plumbing, and electrical systems. A high-end oven, underfloor heating, or a new boiler may add thousands to the budget.
