Frequently Asked Questions

Which type of extension is right for my home?

It depends on your property and how much space you need. We build side, rear and wraparound extensions to add space on the ground floor, as well as two-storey and over-structure extensions when you need extra room upstairs too. Our team will talk you through the options that suit your home before anything is decided.

What can I include in a single-storey extension?

That's up to you. Our single-storey rear extension in Hoddesdon has a fully tiled pitched roof with rooflights, black-framed bifold doors and a smooth plastered finish with recessed lighting. In Hertford, a rear extension made room for a new kitchen, a utility room and a WC, all under one roof.

Do you finish the inside of the extension too?

We do. As well as the building work, we take care of the interior fixtures and decoration, so your new space is ready to use as soon as we hand it over, without you having to bring in anyone else.

Does a kitchen extension add value to a home?

A kitchen extension can add value to your home as well as giving you more space to cook, eat and relax. How much it adds depends on your property and the finished space, and we explore the subject in more detail in our blog post on kitchen extensions.

Can I live at home while my extension is being built?

You can. Much of the work on an extension takes place outside, and wherever possible we put up temporary walls inside your home to keep dust to a minimum while we carry on with the build.

How long does a ground floor extension take?

Most ground floor extensions take around 8 to 10 weeks. Your project plan will set out the timescales before we start, and we'll keep you updated as the work progresses.
