House Extension Builders in Lambeth



We at APT Renovation have a long history of high end residential basement expansion builds. Projects can vary from partial to full build footprint projects & even to the newly fashionable basements jobs where the build print expands out beneath the garden to gain that much needed natural light via light wells.

We perform kitchen extension builds that extend out into the rear of the house. Most commonly these are performed on Victorian, Edwardian & Georgian houses throughout South West London.



Many of the loft conversions carried out in the last year have greatly increased the square meterage of the properties that they were added to. A current trend in the market are additional bedrooms which feature an en suite bathroom.

How much can my house in Lambeth increase after a Loft Conversion or  Extension?

It is not possible to put an exact figure on this as it varies depending on the type of house, the extension work, the age & location of the property. We can however provide some statistics that give a good indication of what you can expect when it comes to adding value with a house extension.

Research performed by mortgages & banks on the value of improvements to an average three bedroom house found that an extension that creates an additional ensuite bedroom or a kitchen extension can add up to 23% the value of your property. A loft conversion could increase the value of the property over 28% like our Canford Road Project. An extra bedroom can add an easy 12% to the value of the home. So when our clients opt for two or three of the mentioned builds as part of one full house renovation, the reselling value of the increased value of the  home can be well worth it!
