Client reviews
The project included adding a carport, extending the front of the house, and enlarging a bedroom to the front of the property. Everything was completed to a high standard, and the craftsmanship speaks for itself. The team was professional and friendly and kept the site clean throughout. Communication was excellent, we were always kept in the loop.

How it works
Simple, start to finish
Most of the stress in building work comes from not knowing what happens next. Pick a stage below and see exactly what happens, what we need from you, and how long it takes.
Hover or tap a stage

First visit
We walk round the property with you, take a proper look at what you have got, and talk through what you want to do. If something will not work, or there is a cheaper way to get most of what you are after, this is when we say so. We measure up and take photographs so we can price the job accurately.
- What we need from you
- Nothing to prepare. Show us round and tell us what you have in mind, even if it is only a rough idea.
- How long it takes
- About an hour, usually within a week of you calling.

Drawings and approvals
We check the constraints on your specific address, conservation area, listing, green belt, protected trees, and tell you whether the job is permitted development, prior approval or a full application. We work alongside your architect and structural engineer, or introduce you to people we have used for years. We handle the building control side.
- What we need from you
- Decide how far you want to take the scheme, then sign off the drawings once you are happy.
- How long it takes
- Permitted development can be a few weeks. A full application usually takes around eight weeks from validation, longer in a conservation area.

A written quote
You get a written, itemised quote setting out what each part of the job costs, so you can see where the money goes and decide what matters to you. No vague day rates, and no single lump sum with nothing behind it. If we can see a genuine unknown, a wall we cannot look behind or ground we have not dug, we tell you and we agree how it will be handled rather than burying it.
- What we need from you
- Read it, ask about anything that is not clear, and tell us what you would like adjusted.
- How long it takes
- Usually within a week or two of the drawings being finalised.

The build
The same team is on your job from the first day to the last, with one person you can ring. We set up properly, protect your drive and garden, and keep the site swept and safe each evening. You always know what is happening the following week, and where we are building near a boundary we serve the party wall notices in good time.
- What we need from you
- Choose kitchens, tiles, sanitaryware and finishes when we ask. We flag each decision deadline well in advance so nothing holds the job up.
- How long it takes
- Roughly 12 to 16 weeks on site for a typical single storey rear extension. Loft conversions are usually 8 to 12 weeks.

Sign off and handover
Building control inspects at the right stages and issues the completion certificate, which we hand to you. Keep it safe, because your buyer's solicitor will ask for it one day. We walk round the finished work with you, write down anything that needs putting right, and come back and do it.
- What we need from you
- Walk round with us and point out anything you are not happy with. We would much rather hear it now than a year later.
- How long it takes
- A few days at the end, with the certificate following afterwards.

Good to know
Questions we get asked a lot
If the answer you need is not here, call us. We would rather spend ten minutes on the phone than have you guess.
We are based on Sheepfold Road in Guildford and work across the borough and the villages around it, including Merrow, Burpham, East Horsley, Godalming, Bramley and Albury. If you are within about half an hour of Guildford, ask us.
Yes. We come out, look at the property, talk through what you want and what is realistic, and then send a written itemised quote. There is no charge and no obligation, and we do not do the sit down sales visit.
We keep the core trades in house, so the same team is on your job from start to finish. Where a job needs a specialist, for example a structural engineer or a specialist roofing detail, we bring in someone we have worked with for years rather than whoever is cheapest that week.
Yes. We will tell you at the first visit which route your job needs, whether that is permitted development, prior approval or a full application, and we work alongside your architect and engineer. We handle the building control side and the sign off at the end.
For a single storey rear extension, plan on roughly 12 to 16 weeks on site once approvals are in place. A loft conversion is usually 8 to 12 weeks. A full house renovation or a new build is a longer programme and we will give you a realistic one before you commit.
Yes, we carry public liability insurance and we are happy to send the certificate before you appoint us. Bell & Collier Construction Ltd is registered in England and Wales, company number 14131831.
