Thinking of a Porch Extension? Here’s Everything You Need to Know

Quick Summary

A porch extension is an affordable way to enhance kerb appeal, improve insulation, and add security to your home. With UK costs typically starting from around £3,000, a well-designed porch offers great value and a stylish, practical upgrade. 

Have you ever thought about the fact that the front part of your home leaves a long-lasting impression on the one who is visiting for the first time or just passing by? Moreover, it also leaves an impact on potential buyers who want to buy the property. 

If the front of your home is not welcoming enough, then you are missing that outdoor spark. And it can be achieved with a porch extension. A porch extension is one of the simplest and cost-effective ways to enhance the front of the house. It not only adds character and aesthetic, but also adds functionality and value to the overall property. 

If we look at some stats for the recent research and findings on value and returns:

• Home extension projects, including porches, can improve property value by 10 – 25 % on average when done well. 
• Some experts report that a well-designed porch could deliver up to an 80 % return on investment (ROI) by increasing curb appeal and resale interest, especially relative to its lower cost.

Why Porch Extension Only? 

There are tons of other options that you can have for home extensions, but for starters front porch extension goes a long way. It not only improves the general appearance of your home but also makes it look much bigger and more functional in terms of usage.

It also provides plenty of advantages, like a short stay period when you enter the house to settle in before meeting the homeowner, and a place to hang coats or leave an umbrella. 

You can also have a shoe storage area to maintain shoe hygiene. For rainy or stormy days, this place also adds a layer of protection. If we consider closed porches, they keep the heat in, saving energy, with the added layer of protection to prevent heat loss through the front door.
