 House Extension Dulwich SW2  

In most cases, people who need more space in their homes look at the value house extension after they have found out exactly how much it costs to sell, move, and buy a new home.  House Extension in Dulwich is usually a much more cost effective solution because it adds value to the home.  When looking at these home extensions, some rooms and upgrades add a lot more value to the home than others, but most builders say don’t do a room extension thinking that when the home is sold the money spent on the remodeling or the extension will be recuperated. 

 For consumers who want to look at the extensions that can add the most value to the house, the room that generally adds the most value to the home is the kitchen.  Not only does a larger, more modern kitchen, add value to the home, it tends to make it much more attractive to potential buyers.  The one rule of thumb that most builders agree on is to make the amount spent on the extension around 10 percent of the value of the home.  For example if the home is worth £400,000, then the amount of the extension should not exceed £40,000.  And it’s also a good idea to build in a “margin of error” and be prepared to add another 20 percent to the cost of the extension.   

Another area that consumers must remember is that value is generally only added when the actual square feet of the home is expanded.  This could be done by adding a basement, expanding the kitchen and adding space onto the kitchen that is done expanding an outside wall instead of an inside wall.  Even a bathroom extension adds value provided it expands existing space in the home and updates the facility.  

With these extension designs, people may expect to pay to extend the house somewhere around £25,000 for a rear extension, up to £70,000 if the house extension is to convert a small basement, and up to £200,000 if completely adding a basement from scratch.  A new bathroom is generally figured at £8,000, expanding the kitchen can be from £25,000 upwards of £170,000, and a two story extension can be an extension design that costs up to £40,000.  

So now that there is an idea of how much the cost can run for a new house extension, let’s look at how much value that adds to the price of the home.  For example, with the enormous costs of a much larger kitchen, expect it to add four percent to the value, a new bathroom up to five percent, a conservatory up to five percent, and the improvement that adds the most is a loft conversion upwards of 21 percent.  

Sigma Construction can provide the architectural design, the required permits, and the construction to complete the building design that provides that dream expansion to the home.  For a good solution to House Extension Dulwich look at the services Sigma Construction provides.    

SE21  

Dulwich is in the southeastern postal code of London SE21 with the neighboring towns of parts of Sydenham Hill, Tulse Hill, Loughborough Junction, and Herne Hill to eastern Dulwich.  This great area has been documented since King Edgar granted the land to Earl Aelfheah in 967 A.D.   This area has been home to a charitable foundation that was founded in 1619 called Alleyn’s College of God’s Gift that includes the school for girls, the college and Christ’s Chapel.   The beautiful Dulwich Park, a wonderful park for horseback riding, rowing on the pond, a lovely picnic area, bowling green, and tennis court, was actually built in 1890.  Some of the oldest churches include All Saints, built in the late 1880’s and the St. Barnabas Church built in 1894. Dulwich sits on the South Circular road and it’s a 12 minute train ride into London and is serviced by several bus routes.
