Tip 1: Estimate your Budget
Work out your budget: how much can you borrow? Speak to your bank about how to release cash flow for your project. Don’t over-borrow as you would not want to put pressure on yourself. If you can only borrow a small amount, it may be better to wait a year or two before starting, and plan other strategies to arrange the finance. Call us to discuss basic shell prices as quoted by our builders.
Tip 2: A Family affair
Speak to your family. Work out what the priorities are, e.g. another bedroom, a larger kitchen / living space, a second bathroom, storage, cloakroom, downstairs loo or utility area. Which ones can be lived without, if not all are feasible? If there are precedents in the area, a basement could be feasible; or if it is a games room you would like, a garden room could fit the bill.
Tip 3: Consult a Planner
Speak to a planning consultant. They can help regarding feasibility assessment for prospective scenarios. Get a couple of quotes for planning services so you can be aware of good value. They will indicate their architect fees for extension plans.
Tip 4: Build Estimates
Speak to a project manager. If your planning consultant works under the same roof as architectural designers and construction support services, you could ask for assistance to plan your budget as part of their free consultation. They will know build estimates for a 2 storey extension cost, kitchen extensions, a bungalow extension or a side extension.
Tip 5: Your Site Survey
Prepare to be at home for the site survey. The technician will spend about 2 hours carefully documenting your home and garden via laser measurements and strategic photographs. They are there in a technical capacity so whilst you can talk to them a little about your ideas, although these are best saved for the briefing. From their measurements, their extension drawings services can be started.
Tip 6: Bring things you like
Prepare some mood shots or a Pinterest folder in advance of your first briefing meeting with the architectural designers. (That way they will design for what you like). It may likely take place in their offices, to avoid a further site consultation fee. This is when you will create a brief, together with the design team. At this point, you may wish to instruct 3D renders to immerse yourself in the prospective change. At this point, changes can be made if you are not sure, as these are – by nature – less exacting than planning drawings. They are also useful to show the planning officer as supportive material, since it is nice for them to see 3D work rather than 2D plans all day.
Tip 7: List your Priorities
Prepare a wish list for your project. Whereas no. 6 can be towards your aesthetic preferences and style, it is also important to list your practical requirements in order of priority, e.g. utility, storage, additional bedroom, double storey etc.
Tip 8: Be slightly Flexible
Be prepared to downscale your proposal slightly if necessary. Your planning consultant will push for the maximum of what you would like to achieve, within the realms of feasibility. A good planning consultant should know the maximum feasible development, so you can choose according to your budget, and which of the various planning routes is the most advisable for your proposal.
Tip 9: What to be Savvy About
It is good to be in the loop about relevant cost indications, for example: have an idea of what structural engineers charge. A good architectural company will commission one for you, as Building Control will want structural calculations & drawings along with your building regulations drawings. A good technical architect will be able to create your Building Regs, as they are more detailed and on a tighter scale than Planning Application drawings. After drawing up plans for an extension application to the planning department, you will need to make an application to Building Control. (For the Building Regulations drawings London architects Extension Architecture have technical staff and vast experience in creating these.)
Tip 10: Consider Tender Packs
Have an idea also of builders’ quotes for your size of project so you can be aware of good value. If your planning / architectural company offer construction support, they will ask their vetted builders to tender for your project. This will ensure your specified materials are used, and not cheaper, inferior ones. You can save 10-15% of your build cost if the architect passes on trade discounts for your materials. (Therefore Tender Packs are like a ‘paper truncheon’ for you.) Your architect may offer Project Management also, which takes the headache out of builder disputes – and puts you in the driving seat – by paying them in arrears.
