A house extension is a significant home improvement project that involves adding extra space to your existing property. This can be achieved by extending the structure outwards or upwards, creating additional rooms or expanding existing ones. House extensions can range from small single-room additions to large multi-room projects that completely transform the layout and functionality of your home. Common types of extensions include:
The cost of a house extension varies widely based on several factors, including the size and type of extension, the materials used, and the complexity of the project. Here are some general cost estimates to help you plan your budget:
These estimates include basic construction costs but may not cover additional expenses such as planning permission, architectural fees, and interior finishes.
A successful house extension project requires the expertise of various tradespeople. Here are the key professionals you will likely need:
In many cases, house extensions require planning permission from your local council. However, some extensions may fall under Permitted Development Rights, which allow for certain types of extensions without the need for formal permission. It’s essential to check with your local planning authority to determine the requirements for your project.
A well-designed and executed extension can significantly increase the value of your home. Extensions that add additional bedrooms, bathrooms, or improve the overall functionality and aesthetics of the property tend to offer the highest return on investment.
The duration of a house extension project depends on the size and complexity of the work. On average, a single-storey extension might take around 3 to 6 months to complete, while more extensive projects, such as double-storey extensions or loft conversions, can take 6 to 12 months or longer. This timeline includes planning, design, construction, and finishing phases

My name it’s Cris. I am a person with many qualities in handyman.What a handyman means? A handyman, also known as a handyperson or handyworker, is a person skilled at a wide range of repairs, typically around the home. These tasks include trade skills, repair work, maintenance work, are both interior and exterior, and are sometimes described as "side work", "odd jobs" or "fix-up tasks". For me a handyman means the person who helps the people who are in need or not having the necessary training for that thing and at the same time the one who later gives a smile to the people's face. For this, please contact me in any need you have

Initial service was great. But grass that was laid hasn’t last a year with a lot of patches and bits that have died. I watered and cut the grass regularly as I trusted but the grass just hasn’t lasted. Unfortunately, after several requests for help, Christian hasn’t been very responsive and showing no signs of helping.
