GENERAL QUESTIONS

If you have a question that’s not listed here please don’t hesitate to contact us, we’re always here to help. We want you to be happy when you choose a company to do your house extension so we’ve complied a list of commonly asked questions.

FAQ's

We have completed many house extension into kitchens, bedrooms, offices, and kid’s playroom, “granny flats” with en suits… the list is endless. We can show you our portfolio and discuss your needs. We will work
with you to get what you want.

It all depends on your requirements, for example a small extension will cost less than a big extension. Cost will increase with extras such as an en-suite bathroom or if you wish to have a kitchen designed
and fitted.

According to property experts, a house extension does not only provide extra living space but can add up to 10% to the value of your home.

A single integral house extension takes on average 2-3 months. A double house extension will take on average 3-4 months. These may change due to your requirements.

In the majority of cases, the work involved in a house extension will be classed as permitted development. However, if you live in a Conservation Area, a location where development can be restricted to protect the appearance of the surroundings, or on a new estate with strict guidelines, it’s worth checking what’s allowed- we will take care of this for you.

You’ll need building regulations consent and sign off for the various elements of your build, as with other home alterations. We will check that your local council is happy with your plans before starting work and organise appointments for each stage of the job. Alternatively we will use the private building control firm we use called Compagna.

We take a deposit in the region of 15% to 20% of the overall job value. We will then advise you of a payment schedule where you pay a certain percent at different stages through the job. We will provide the breakdown before the contracts are signed. We take the final payment once you are 100% satisfied with our work.

Once you have agreed to a start date we will send over a copy of the terms and conditions and a contract. Both parties will sign and both have a copy.

We provide a 10 year guarantee on all our work. A certificate will be provided on completion of the job, along with any other certificates such as electrical certificate or gas certificate.

We will always have an ongoing job which may be local to yourselves. We highly recommend you go and speak with our past clients.

Yes, if it is still in production (or remaining stock can be sourced from somewhere). If not we will get you the very best alternative match. We use a professional brick matcher, who will come to site prior to us starting the job. They will provide a few brick samples for you to choose from.

We put down a visqueen sheet and cover the drive with plywood to protect the drive from skips and general building work. We protect the internal by using dust sheets. We guarantee to keeping the mess on site to a minimum and leave the in the condition it was when we first arrived. We understand this is your home so will cause as little disruption as possible.

Our Customer reviews

“We would highly recommend Matt at No 1 House Extensions, from start to finish we were really very pleased with the standard of work. Matt is a perfectionist and made sure that we were happy with the work every step of the way. He
was also really helpful and suggested some brilliant ideas that we would never have thought of and they ended up looking fantastic. On the day that the bricks arrived Matt was not happy with the colour match so he sent them away and
went to a different supplier to get a better match, the result is that the conversion looks like it has always been there. Matt is a very genuine, trustworthy and conscientious person and we are very happy we decided to go with his
company”.

We would 100% recommend no 1 extensions & conversions. The team, especially Paul and James, have worked exceptionally hard on our garage conversion into a bedroom and bathroom. They’ve listened to us and come up with options and guided us in making decisions based on their expertise. They were always on time, sometimes staying late too get the work done. Matt kept us informed throughout. The team were all courteous and professional at all times. The quality and finish is to a very high standard and everything we had hoped for.
We’re really happy with the conversion, and that we chose Matt and his team to do the work.

Matt and his team did a great job on our extension despite a big structural issue causing them problems / delays. We lived in the house the whole time so it really helped that the team are a lovely set of lads who kept the place as tidy as possible. The house now is exactly how we wanted and Matt and team have made awkward spaces usable. Their attention to detail, such as reusing old bricks and purchasing bricks to match the existing exterior, have made all the difference.
We would recommend Matt and his team !!

Highly recommend No1 extensions if you’re looking for a reliable team for your extension. Everyone in the team are so friendly and all the work were completed in high standard! I was a little dubious when looking for trade as there are many cow boy builders out there, but No 1 extensions have given me hope that there are good builders out there. The price was reasonable and Matt even went over and beyond to carry out extra work for me. Thank you again.

Hi I would like to thank Matt and his fantastic work force for doing my extension. They were very professional and would help you in anyway they could. The house looks great now. I would definitely recommend these guys for doing your extension I have full confidence they will do a good professional job for you. If you have any issues speak to Matt or Nick they will give you great advice.

We had a fantastic experience with No1 Extensions. They were quick and professional and our final conversion exceeded our expectation. It only took them 5 -7 days from start to finish which was amazing. Paul and James were professional, on time and easy going and respectful. And Chandra was really informative and helpful over the phone. Thanks!

The team at no1 extensions and conversions were amazing from start to finish. They were professional throughout and made sure we were involved from start to finish. Would definitely recommend to anyone thinking of having a conversion at a very competitive price.

Very very pleased with our garage conversion.
We now have a lovely double bedroom with a beautiful en-suite.
It is better than we envisaged.
Particular thanks to Paul, and James who had a great work ethic, and delivered a very high standard of workmanship.
They were respectful, and involved us in decision making consistently.
Other builders and trades are not always so respectful.
Paul, and James had music playing, but at a low acceptable level, and we never heard any expletives.
The other trades involved, electricians, brickies, plumber/heating engineer. roofers etc also were very good, and respectful.
Would recommend No.1 Extensions, and Garage Conversions unreservedly.
