Anthony C Esposito
House Extension Professionals in Philadelphia, PA
Average rating: 5 out of 5 stars6 March 2014
“We hired Anthony to design and renovate our small South Philly basement. He and his team (big shout out to my main man Chuck!) did an amazing job. It required some significant D&E and juggling several different teams. Anthony was on the job and available 24/7, keeping us up to date via text, emails and phone calls. He worked quickly and used his extensive connections to find us quality products on a budget. When issues popped up totally unrelated to his work, Anthony worked with our previous contractors to identify the issue, come up with a solution, and got them to pay 100% of the cost. Without Anthony we would have been out of luck! To this day, we go back to Anthony with questions and requests for recommendations and he always comes through. Like our concierge contractor! Hire Anthony, you'll be happy you did! (Yes I'm a real person and no I'm not a blood relative - have Anthony put me in touch with you if you need a reference)”
Hellings Builders
House Extension Professionals in Philadelphia, PA
Average rating: 5 out of 5 stars11 June 2013
“We purchased a new home from Hellings and have used Hellings to finish the lower level as well as other projects. Ross, Barry and his whole team are very focused on client satisfaction. There are always issues to deal with in large projects and our experience continues to be that Hellings is focused on getting things done the right way. Since buying our home and adding to the original house, we've used Hellings to put in a whole house generator, to install estate fencing and will certainly have them provide a bid on a pool and patio project that we also have on our list. Hellings is not trying to be the low cost option, but they take pride in doing each project the right way.”
Osborne Construction
House Extension Professionals in Philadelphia, PA
Average rating: 5 out of 5 stars29 April 2013
“Brian is great to work with because he has great ideas and is an excellent crafts person. He keeps the client informed about the time frame for a project and does a good job co-ordinating subcontractors. He has drywalled and tiled a basement bathroom for me, completely rebuilt my front porch using mahogany decking and last fall gutted my upstairs bathroom, removed the tub, installed a marble shower, installed two custom walnut cabinets and added an attic fan and an exhaust fan. The job was not cheap, however the quality is top shelf and I have no regrets. Also he is very pleasant and his team is skilled and polite.”

Average rating: 5 out of 5 stars1 August 2023
“I would highly recommend Jack and his team to anyone! And already have! Our neighbors recommended him to us after their bathroom reno and our other neighbors will be using him in the fall for theirs. He’s the best! We renovated 2.5 bathrooms this spring with Jack. His quote came in where we were hoping which was great. But more importantly for us was the quality of the work and ease of working with him and his team. Jack is very responsive, timely, and always follow through, which we have learned is difficult to find. Whenever I got stressed, Jack always remained calm and addressed any concerns right away. Truly Jack and his team were a pleasure to work with. I would not hesitate to use them again for any future projects! (See pics of Northern Liberties bathrooms for our reno)”

Builder FAQs
A house extension is a construction process that involves expanding the footprint of your existing home. This could be extending outwards, either to the side or rear of the house, or upwards by adding another storey. House extensions provide extra living space and can significantly increase the value of your property.

House extensions can be categorised based on direction, structure and function. The main types include rear extensions, side return extensions, wrap-around extensions, and double or single-storey extensions. More specific ones could be kitchen extensions, loft conversions, basement conversions, garage conversions or conservatories. Select the type that best suits your property and meets your space needs, if you are unsure, speaking with a local home extension builder in Philadelphia.

Generally, house extensions are worth the investment. They provide additional living space and can dramatically increase the resale value of your home, often covering the initial investment cost. However, plan carefully and choose a reputable house extension builder to ensure a high-quality build that will add value to your property.

The cost of a house extension can vary significantly based on several factors, such as the size, complexity of the design, quality of materials used, and geographical location. However, as a rough estimate, a single-storey extension can range from £1,000 to £2,000 per square metre, whereas a two-storey extension can start at around £1,500 per square metre.

Planning a house extension involves several stages, including idea generation, design, planning permission, and construction. Consult with a house extension architect to create a design based on your needs and budget. Ensure to check with your local council about planning permissions. Finally, choose a reputable house extension builder to bring your vision to life.
