London House Extensions

House Extensions

The most common alteration work we do is simple extension, supporting upper floors or even entire buildings. Ealing Builders, are building contractors in London specialising in house extensions and loft conversions.

If you want to add an extension to your house think about the purpose of your extension. Is it going to be self-contained area for use as a separate home, an extra space for growing family, a commercial use or an investment to increase the value of your property, you should draw out some plans and list of your ideas.

Our fully qualified architects will draw up plans for submission to the planning department in your local Council. We can negotiate on your behalf with the council and keep you informed on the progress. Applying for planning permission could be a slow process especially if you are refused at first time or there are some objections.

At this stage our fee for architect will start at around £ 750 for a small extension. Our extension designer will explain beforehand what services are required and what is included in their professional fees. Once we obtain planning permission our architect will have to submit detailed technical plans required for the building control authority’s approval. For this stage architect’s fee may be additional £ 750 for small extension.

Ealing Builders will provide you with some quotes and sign the contract. Please note that our estimate can be revised until you have agreed a written quote for work. We can give you fixed quote for your extension providing that extension is detailed, post-planning architectural drawings have been produced and IES Limited builder has visited the property to discuss your requirements and has done survey of the site conditions. Contract between the client and Ealing Builders Limited will be signed by both parties before work commences. Fixed quote will form part of this contract.

London House Extension Prices may range between £ 20,000 and £ 70,000. There is no precise formula for obtaining an accurate cost for your extension (apart from a fixed quote from a builder). We have worked out an indicative price guide for building extension in London. A typical ground floor extension may bear a cost of around £ 30,000 – £ 50,000.

Please note, that price for home extension will vary depending on several factors: location of the house, ground conditions, quality of finishes: electrical, plumbing work, fitting a kitchen, bathroom and type of extension required.

One-storey extensions are more common; however two-storey extension can create additional space without going into the loft. Adding two storeys extension doesn’t mean that it will cost you twice as much. Just multiply the figure for a single storey by two and deduct 20% to get indication cost.

The most common size of extension is 15 to 25 square meters, which may bear a construction cost between £ 21,000 and £ 33,000 (excluding the interior fitting). The cost for interior fitting ranges from £ 10,000 to 20,000 for a small single storey extension.

We also offer complete Peace of Mind with our Guarantee.
