“William Honor did 4 large jobs for me. The best part about BluStar is they are 100% honest and do not play games with either your money or your time. That means a quality job without over-runs, and all expectations were met or excided. Billy did 2 bathrooms, a kitchen and a large extension. Oh, and a deck. I know that sounds like a lot and it was, but I never had to sweat the details.”

“Seifert PMC is a terrific small company serving the East End of Long Island. I have worked with Sebastian and his crew on several occasions, fairly big jobs and not so big.

The Seifert team was always dependable and reasonably priced for their excellent work. I would strongly recommend their property mgmt and construction services to anyone. Sumner P”

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 Greenport.

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.
