How to brief your extension architect in Wimbledon
A successful home extension begins with a clear conversation about how you want to live. Before deciding on a larger kitchen, a glazed garden room or a new bedroom, ask what your present home makes difficult. Is the family squeezed around the dining table? Does working from home mean borrowing a corner of the sitting room? Are everyday rooms disconnected from the garden?
For homeowners in Wimbledon and across south-west London, an architectural brief is a practical way to turn those frustrations into priorities. It does not need to be a finished design. It needs to explain the life the design should support.
Start with your daily routine
Write down what happens in your home on a normal weekday and at the weekend. Consider cooking, eating, working, relaxing, welcoming guests and finding somewhere quiet. Describe where activities conflict and where a room is underused.
Then separate needs from preferences. A place to work without interruption may be essential; its exact position may be open to discussion. More storage may matter more than another room. This distinction gives your architect room to explore alternatives rather than simply reproduce a sketch.
Include what you already value. A familiar view, an existing staircase or a quiet corner of the garden may deserve protection. The brief should record what must stay as clearly as what needs to change.
Think about the whole home
An extension is an opportunity to reconsider how existing and new spaces work together. In your brief, ask how the entrance, circulation, storage and garden connection should feel after the work is complete. Avoid treating the additional floor area as a separate box.
Consider what an open-plan arrangement would mean for noise, privacy and daily use. Do you want one shared space, or places that can be closed off? Would a separate utility room make more difference than a larger kitchen? These are useful questions to settle before choosing finishes.
Our refurbishment and extension service includes side and rear extensions, garden room extensions, and loft and basement conversions. The appropriate approach starts with your home and priorities, rather than an assumption that the largest intervention is the best one.
Bring references, with reasons
A small collection of images is more useful when you explain what you like about each. You might be responding to the warmth of a material, the proportions of a window or the relationship between a dining space and a terrace. You may dislike another aspect of the same photograph.
Use references as a language for the conversation, not a promise that another home can be reproduced on your site. Add notes about atmosphere and use: calm, private, easy to maintain, comfortable for visitors. Your architect can then test how those aims might work within the character and constraints of your property.
Be clear about budget and timing
State your overall spending limit early and ask what it needs to cover. Discuss construction, professional services, applications, surveys, tax where applicable, and an allowance for uncertainty. If you have a separate budget for furniture or landscaping, say so. A construction figure and a total project budget are different things.
Explain which dates are fixed and which are preferences. A school move or a change in household circumstances may shape the programme. Tell your architect whether you intend to remain in the home during the work, or whether temporary accommodation is an option. These are decisions to discuss, not commitments to make before the scope is understood.
At Harper Latter Architects, the first stage of our published process is the outline proposal and brief, including your plans and budget. That is the right point to establish the priorities that later design decisions will be measured against.
Identify constraints before fixing the design
Bring any existing drawings, previous planning decisions and information about earlier alterations that you hold. Ask your architect what further surveys or specialist advice may be needed. You do not have to resolve every technical question before the first meeting.
Planning permission and building regulations are separate matters. In England, some house extensions can proceed under permitted development rights, but only within the relevant limits and conditions. Earlier extensions and restrictions on those rights can affect the position. Most extensions also require building regulations approval.
Whether your home is in Merton, Richmond or Kingston, avoid assuming that a neighbour's permission establishes what is possible for yours. Check the property's circumstances and the relevant planning authority's requirements. This article is a starting point for a brief, not a determination of the consents your project needs.
Arrive with a useful first brief
Aim for a short document containing your daily needs, what you want to retain, your priorities, reference images, budget and timing. Add the questions you cannot yet answer. An honest uncertainty is more useful than a decision made too early.
