Understandably people want to know how much a project is going to cost before getting started. It’s a question we always get asked but one that is very difficult to answer. We try to explain by like this, If you wanted buy a car and you asked someone to give you a price for a car you could get quoted £500 or £1 million pounds. The final cost of the car will depend on many factors including make, model, optional extras etc etc. The same is very true of costing up a build project as its very difficult to get an accurate price until you have a detailed specification.

In General there are a number of factors that determine your project budget including:

1. Location
The cost of labour and material in certain parts of the country such as London is higher than the rest of the country 

2. General economic conditions
In difficult times it is worth getting a number of quotes as prices do seem to vary more as some builders price more competitively. The amount of work that a builder has can affect pricing as well as the cost of materials and the VAT rate.

3. Size and complexity of the project
Obviously the scale of the project will be a determining factor in your budget as more materials and time are needed for larger projects however this is not the whole picture. The complexity of the project can also have an impact on the price which is why a good set of drawings are advisable at the outset. Issues such as position of drains, whether a building is listed or is in a conservation area and countless other factors can all have an influence on the final price.

4. Specification and fit out
This is the area that really does vary enormously and one where your budget can really run away with you. The type of materials that you specify in the build and also the materials that you use in the fit out of your project will have a huge impact on your budget so it’s wise to keep this in mind when purchasing bathroom fittings, kitchens etc.

Using an architect will ensure that the correct information is provided and accurate quotes are obtained. Having your architect prepare a schedule of works and detail level drawings will also mean that there is less changes throughout the build phase and therefore less chance of your budget changing.

However if you want to get a ball park figure an approximation of £1500 to £2500 per square metre depending on specification could be used although we would always urge you to get a set of construction drawings before getting any detailed pricing.

Robert offers a very professional service. His vision for the space was aligned with ours, so that is why we wanted to work with him to fully... renovate our house. He advised us that we could reconfigure the loft conversion under permitted development and go down the planning application route for the single story rear extension. He drew up plans, providing various different options, and was open to our suggestions for changes. Robert drew up our plans, submitted our applications and ran our tender process to select an appropriate builder. We were very happy with Robert's more

We decided to engage Urbane to design, submit planning and arrange the tender process with builders after speaking to a number of local architects... and builders. The project involves an internal redesign, extension to rear, side and loft. Robert has come up with amazing design ideas, bearing in mind our budget and focused on how we wanted to use the space. Project is currently in build phase Happy to recommend and provide a more

We used Urbane Designs to renovate and extend our house. From initial consultation to completion, Robert was a pleasure to work with. We'd never... taken on a project like this before, but Robert was great at setting out each stage of the process, with transparent, itemised costs for each. He was also very responsive and helpful with our (many) questions, and of course came up with an excellent design for our more

We've used Rob Speight and Urbane Architects twice over the last 10 years. Once to do a ground floor extension and refurbishment and then once to do... a loft and first floor extension.On both occasions Rob was clear and responsive in communication and thoughtful and adaptable in design. We certainly wouldn't have used Urbane a second time if they had not done a good job the first time round (and we did encounter problems with some of our contractors first time). more

Urbane Design Architects are a wonderful team to work with. Over the course of 18 months they supported us with feasibility, planning permission,... tendering the job, building control approval and contract administration with the builder. Together we carried out a major renovation including a basement, ground floor and 1st floor rear extension. Robert Speight & his team were incredibly responsive throughout, producing exciting and effective designs with lots of detail.I would have no hesitation in recommending Urbane Design Architects to my family & friends, they were a great pleasure to deal with more

Most definitely 5 stars! We had a great experience with Urbane Design Architects and their team when we recently extended and reconfigured the... ground floor of our Georgian terraced house in Chiswick W4. Robert Speight was our project architect. He listened to our brief but then made us consider some alternative, exciting ways of thinking about the spaces and materials. He combined his experience of local planning policies, working relationships with local suppliers and our budget to deliver a new home that we are in love with! When we were going through planning permissions and the tender process, the team walked us through all the requirements step by step with us, which was great. Very highly recommended and sensibley priced!read more
